A field of biology concerned with the development of techniques for the collection and manipulation of biological data, and the use of such data to make biological discoveries or predictions. This field encompasses all computational methods and theories for solving biological problems including manipulation of models and datasets.
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
Gene Expression Profiling
Embryonic Stem Cells
Stem Cell Transplantation
The transfer of STEM CELLS from one individual to another within the same species (TRANSPLANTATION, HOMOLOGOUS) or between species (XENOTRANSPLANTATION), or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). The source and location of the stem cells determines their potency or pluripotency to differentiate into various cell types.
Neoplastic Stem Cells
Allergy and Immunology
Critical and exhaustive investigation or experimentation, having for its aim the discovery of new facts and their correct interpretation, the revision of accepted conclusions, theories, or laws in the light of newly discovered facts, or the practical application of such new or revised conclusions, theories, or laws. (Webster, 3d ed)
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Gene Expression Regulation
Linear POLYPEPTIDES that are synthesized on RIBOSOMES and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein.
The use of instrumentation and techniques for visualizing material and details that cannot be seen by the unaided eye. It is usually done by enlarging images, transmitted by light or electron beams, with optical or magnetic lenses that magnify the entire image field. With scanning microscopy, images are generated by collecting output from the specimen in a point-by-point fashion, on a magnified scale, as it is scanned by a narrow beam of light or electrons, a laser, a conductive probe, or a topographical probe.
Gene Regulatory Networks
Interacting DNA-encoded regulatory subsystems in the GENOME that coordinate input from activator and repressor TRANSCRIPTION FACTORS during development, cell differentiation, or in response to environmental cues. The networks function to ultimately specify expression of particular sets of GENES for specific conditions, times, or locations.
Green Fluorescent Proteins
Microfluidic Analytical Techniques
Stem Cell Niche
Body of knowledge related to the use of organisms, cells or cell-derived constituents for the purpose of developing products which are technically, scientifically and clinically useful. Alteration of biologic function at the molecular level (i.e., GENETIC ENGINEERING) is a central focus; laboratory methods used include TRANSFECTION and CLONING technologies, sequence and structure analysis algorithms, computer databases, and gene and protein structure function analysis and prediction.
Oligonucleotide Array Sequence Analysis
Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.
The process that reverts CELL NUCLEI of fully differentiated somatic cells to a pluripotent or totipotent state. This process can be achieved to a certain extent by NUCLEAR TRANSFER TECHNIQUES, such as fusing somatic cell nuclei with enucleated pluripotent embryonic stem cells or enucleated totipotent oocytes. GENE EXPRESSION PROFILING of the fused hybrid cells is used to determine the degree of reprogramming. Dramatic results of nuclear reprogramming include the generation of cloned mammals, such as Dolly the sheep in 1997.
Metabolic Networks and Pathways
Amino Acid Sequence
The complex series of phenomena, occurring between the end of one CELL DIVISION and the end of the next, by which cellular material is duplicated and then divided between two daughter cells. The cell cycle includes INTERPHASE, which includes G0 PHASE; G1 PHASE; S PHASE; and G2 PHASE, and CELL DIVISION PHASE.
Manufacturing technology for making microscopic devices in the micrometer range (typically 1-100 micrometers), such as integrated circuits or MEMS. The process usually involves replication and parallel fabrication of hundreds or millions of identical structures using various thin film deposition techniques and carried out in environmentally-controlled clean rooms.
Gene Expression Regulation, Developmental
Multicellular, eukaryotic life forms of kingdom Plantae (sensu lato), comprising the VIRIDIPLANTAE; RHODOPHYTA; and GLAUCOPHYTA; all of which acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations.
Small double-stranded, non-protein coding RNAs, 21-25 nucleotides in length generated from single-stranded microRNA gene transcripts by the same RIBONUCLEASE III, Dicer, that produces small interfering RNAs (RNA, SMALL INTERFERING). They become part of the RNA-INDUCED SILENCING COMPLEX and repress the translation (TRANSLATION, GENETIC) of target RNA by binding to homologous 3'UTR region as an imperfect match. The small temporal RNAs (stRNAs), let-7 and lin-4, from C. elegans, are the first 2 miRNAs discovered, and are from a class of miRNAs involved in developmental timing.
A gene silencing phenomenon whereby specific dsRNAs (RNA, DOUBLE-STRANDED) trigger the degradation of homologous mRNA (RNA, MESSENGER). The specific dsRNAs are processed into SMALL INTERFERING RNA (siRNA) which serves as a guide for cleavage of the homologous mRNA in the RNA-INDUCED SILENCING COMPLEX. DNA METHYLATION may also be triggered during this process.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
A genetic process by which the adult organism is realized via mechanisms that lead to the restriction in the possible fates of cells, eventually leading to their differentiated state. Mechanisms involved cause heritable changes to cells without changes to DNA sequence such as DNA METHYLATION; HISTONE modification; DNA REPLICATION TIMING; NUCLEOSOME positioning; and heterochromatization which result in selective gene expression or repression.
Autobiography as Topic
Silicone polymers which consist of silicon atoms substituted with methyl groups and linked by oxygen atoms. They comprise a series of biocompatible materials used as liquids, gels or solids; as film for artificial membranes, gels for implants, and liquids for drug vehicles; and as antifoaming agents.
One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.
The molecular designing of drugs for specific purposes (such as DNA-binding, enzyme inhibition, anti-cancer efficacy, etc.) based on knowledge of molecular properties such as activity of functional groups, molecular geometry, and electronic structure, and also on information cataloged on analogous molecules. Drug design is generally computer-assisted molecular modeling and does not include pharmacokinetics, dosage analysis, or drug administration analysis.
Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.

Protein Structure, Tertiary
The level of protein structure in which combinations of secondary protein structures (alpha helices, beta sheets, loop regions, and motifs) pack together to form folded shapes called domains. Disulfide bridges between cysteines in two different parts of the polypeptide chain along with other interactions between the chains play a role in the formation and stabilization of tertiary structure. Small proteins usually consist of only one domain but larger proteins may contain a number of domains connected by segments of polypeptide chain which lack regular secondary structure.
Translational Medical Research
Filamentous proteins that are the main constituent of the thin filaments of muscle fibers. The filaments (known also as filamentous or F-actin) can be dissociated into their globular subunits; each subunit is composed of a single polypeptide 375 amino acids long. This is known as globular or G-actin. In conjunction with MYOSINS, actin is responsible for the contraction and relaxation of muscle.
Reverse Transcriptase Polymerase Chain Reaction
Measurable and quantifiable biological parameters (e.g., specific enzyme concentration, specific hormone concentration, specific gene phenotype distribution in a population, presence of biological substances) which serve as indices for health- and physiology-related assessments, such as disease risk, psychiatric disorders, environmental exposure and its effects, disease diagnosis, metabolic processes, substance abuse, pregnancy, cell line development, epidemiologic studies, etc.
Gene Expression Regulation, Neoplastic
The science and application of a double-beam transmission interference microscope in which the illuminating light beam is split into two paths. One beam passes through the specimen while the other beam reflects off a reference mirror before joining and interfering with the other. The observed optical path difference between the two beams can be measured and used to discriminate minute differences in thickness and refraction of non-stained transparent specimens, such as living cells in culture.
Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)
Satellite Cells, Skeletal Muscle
The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
Sequence Analysis, DNA
A tube-like invagination of the EPIDERMIS from which the hair shaft develops and into which SEBACEOUS GLANDS open. The hair follicle is lined by a cellular inner and outer root sheath of epidermal origin and is invested with a fibrous sheath derived from the dermis. (Stedman, 26th ed) Follicles of very long hairs extend into the subcutaneous layer of tissue under the SKIN.
Cell Transformation, Neoplastic
Highly specialized EPITHELIAL CELLS that line the HEART; BLOOD VESSELS; and lymph vessels, forming the ENDOTHELIUM. They are polygonal in shape and joined together by TIGHT JUNCTIONS. The tight junctions allow for variable permeability to specific macromolecules that are transported across the endothelial layer.
Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.
RNA, Small Interfering
Small double-stranded, non-protein coding RNAs (21-31 nucleotides) involved in GENE SILENCING functions, especially RNA INTERFERENCE (RNAi). Endogenously, siRNAs are generated from dsRNAs (RNA, DOUBLE-STRANDED) by the same ribonuclease, Dicer, that generates miRNAs (MICRORNAS). The perfect match of the siRNAs' antisense strand to their target RNAs mediates RNAi by siRNA-guided RNA cleavage. siRNAs fall into different classes including trans-acting siRNA (tasiRNA), repeat-associated RNA (rasiRNA), small-scan RNA (scnRNA), and Piwi protein-interacting RNA (piRNA) and have different specific gene silencing functions.
One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.
One of the three domains of life (the others being BACTERIA and ARCHAEA), also called Eukarya. These are organisms whose cells are enclosed in membranes and possess a nucleus. They comprise almost all multicellular and many unicellular organisms, and are traditionally divided into groups (sometimes called kingdoms) including ANIMALS; PLANTS; FUNGI; and various algae and other taxa that were previously part of the old kingdom Protista.
A kingdom of eukaryotic, heterotrophic organisms that live parasitically as saprobes, including MUSHROOMS; YEASTS; smuts, molds, etc. They reproduce either sexually or asexually, and have life cycles that range from simple to complex. Filamentous fungi, commonly known as molds, refer to those that grow as multicellular colonies.
Image Processing, Computer-Assisted
How cells (might) sense microgravity. (1/414)This article is a summary of a lecture presented at an ESA/NASA Workshop on Cell and Molecular Biology Research in Space that convened in Leuven, Belgium, in June 1998. Recent studies are reviewed which suggest that cells may sense mechanical stresses, including those due to gravity, through changes in the balance of forces that are transmitted across transmembrane adhesion receptors that link the cytoskeleton to the extracellular matrix and to other cells (e.g., integrins, cadherins, selectins). The mechanism by which these mechanical signals are transduced and converted into a biochemical response appears to be based, in part, on the finding that living cells use a tension-dependent form of architecture, known as tensegrity, to organize and stabilize their cytoskeleton. Because of tensegrity, the cellular response to stress differs depending on the level of pre-stress (pre-existing tension) in the cytoskeleton and it involves all three cytoskeletal filament systems as well as nuclear scaffolds. Recent studies confirm that alterations in the cellular force balance can influence intracellular biochemistry within focal adhesion complexes that form at the site of integrin binding as well as gene expression in the nucleus. These results suggest that gravity sensation may not result from direct activation of any single gravioreceptor molecule. Instead, gravitational forces may be experienced by individual cells in the living organism as a result of stress-dependent changes in cell, tissue, or organ structure that, in turn, alter extracellular matrix mechanics, cell shape, cytoskeletal organization, or internal pre-stress in the cell-tissue matrix.--Ingber, D. How cells (might) sense microgravity. (+info)
Mapping the literature of cytotechnology. (2/414)The major purpose of this study was to identify and assess indexing coverage of core journals in cytotechnology. It was part of a larger project sponsored by the Nursing and Allied Health Resources Section of the Medical Library Association to map the literature of allied health. Three representative journals in cytotechnology were selected and subjected to citation analysis to determine what journals, other publication types, and years were cited and how often. Bradford's Law of Scattering was applied to the resulting list of cited journals to identify core titles in the discipline, and five indexes were searched to assess coverage of these core titles. Results indicated that the cytotechnology journal literature had a small core but wide dispersion: one third of the 21,021 journal citations appeared in only 3 titles; another third appeared in an additional 26 titles; the remaining third were scattered in 1,069 different titles. Science Citation Index Expanded rated highest in indexing coverage of the core titles, followed by MEDLINE, EMBASE/Excerpta Medica, HealthSTAR, and Cumulative Index to Nursing and Allied Health Literature (CINAHL). The study's results also showed that journals were the predominantly cited format and that citing authors relied strongly on more recent literature. (+info)
Antibodies and sperm survival in the female tract of the mouse and rabbit. (3/414)Rabbit and mouse spermatozoa from male and female tracts have been examined for their species-antigenic surface character, and for adherent antibodies, by double immunofluorescence techniques. Mouse spermatozoa from the ductus deferens showed an area over the acrosome which was positive to anti-mouse serum that had been absorbed with some male mouse somatic tissues including blood, but those from the uterus and oviduct were not stained. Spermatozoa from the uterus were shown to have an antibody coat on the acrosome, with anti-mouse IgG, but those from the ductus deferens and oviduct did not. Rabbit spermatozoa were more variable but their activity was similar: ejaculated spermatozoa sometimes already had antibody of male origin; the majority of the spermatozoa arriving early in the uterus were coated, but in general those that attained the oviducts were not coated. The results are interpreted as evidence for selection by the female tract of a small antigenically different population; the majority of spermatozoa are rejected and/or destroyed. (+info)
A new miniature hydrostatic pressure chamber for microscopy. Strain-free optical glass windows facilitate phase-contrast and polarized-light microscopy of living cells. Optional fixture permits simultaneous control of pressure and temperature. (4/414)This paper describes the development of a miniature, temperature-controlled, stainless steel pressure chamber which uses strain-free optical glass for windows. It is directly adaptable to standard phase-contrast and polarized-light microscopes and requires a minimum amount of equipment to generate and measure pressure. Birefringence retardation (BR) og 0.1 nm up to 3,000 psi, 0.4 nm up to 5,000 psi and 1.0 nm up to 10,000 psi can be detected over a 0.75-mm central field with two strain-free Leitz 20 times UM objectives, one used as a condenser. In phase-contrast studies a Nikon DML 40 times phase objective and Zeiss model IS long working-distance phase condenser were used, with little deterioration of image quality or contrast at pressures as high as 12,000 psi. The actual design process required a synthesis of various criteria which may be categorized under four main areas of consideration: (a) specimen physiology; (b) constraints imposed by available optical equipment and standard microscope systems; (c) mechanical strength and methods for generating pressure; and (d) optical requirements of the chamber windows. Procedures for using the chambers, as well as methods for shifting and controlling the temperature within the chamber, are included. (+info)
A brief history of the Japan Society for Cell Biology. (6/414)The Japan Society for Cell Biology (JSCB) was first founded in 1950 as the Japan Society for Cellular Chemistry under the vigorous leadership of Seizo Katsunuma, in collaboration with Shigeyasu Amano and Satimaru Seno. The Society was provisionally named as above simply because cell biology had not yet been coined at that time in Japan, although in prospect and reality the Society was in fact for the purpose of pursuing cell biology. Later in 1964, the Society was properly renamed as the Japan Society for Cell Biology. After this renaming, the JSCB made great efforts to adapt itself to the rapid progress being made in cell biology. For this purpose the Society's constitution was created in 1966 and revised in 1969. According to the revised constitution, the President, Executive Committee and Councils were to be determined by ballot vote. The style of the annual meetings was gradually modified to incorporate general oral and poster presentations in addition to Symposia (1969-1974). The publication of annual periodicals in Japanese called Symposia of the Japan Society for Cellular Chemistry (1951-1967) and later Symposia of the Japan Society for Cell Biology (1968-1974) was replaced by a new international journal called Cell Structure and Function initiated in 1975. This reformation made it possible for the Society to participate in the Science Council of Japan in 1975 and finally in 1993 to acquire its own study section of Cell Biology with grants-in-aid from the Ministry of Education and Science, Japan. The JSCB hosted the 3rd International Congress on Cell Biology (ICCB) in 1984 and the 3rd Asian-Pacific Organization for Cell Biology (APOCB) Congress in 1998, thus contributing to the international advancement of cell biology. Now the membership of JSCB stands at approximately 1,800 and the number of presentations per meeting is 300 to 400 annually. Although a good number of interesting and important findings in cell biology have been reported from Japan, the general academic activity of the JSCB is far less than one might expect. This is simply due the fact that academic activity in the field of cell biology in Japan is divided among several other related societies such as the Japan Society for Molecular Biology and the Japan Society for Developmental Biology, among others.

Myocardial lysis in acute rheumatic fever followed by regeneration of cardiac muscle and origin of Aschoff bodies. (7/414)In acute rheumatic heart disease, lysis of cardiac muscle fibres with or without retention of sarcolemma is found to be the most damaging feature in many cases. In deeper myocardium the cellular lysis often forms anastomosing clefts or sinus-like spaces between surviving muscle bundles and in the outer portion of myocardium cellular lysis may leave the sarcolemma more or less intact. From lysing cardiac muscle fibres there arise dedifferentiated cells with remarkable potentiality for regeneration. For the origin of these dedifferentiated cells, which are often indistinguishable from lymphocytes, no mitosis is seen in cardiac muscle cells. The successive stages of development of muscle cell from these dedifferentiated cells within the remaining or newly formed sarcolemma have been observed in this study. This study infers that the increased number of fibrous septa, when seen, denotes the tracks of previous muscle degeneration and subsequent replacement of it with incomplete muscle regeneration and fibrous tissue formation. In an area of muscle lysis the origin of Aschoff bodies from these dedifferentiated cells has been followed. Ashoff bodies arising in this was behave as an abortive and atypical growth of muscle fibres in a nodular fashion specific to rheumatic fever. (+info)
Papanicolaou tests diagnosed as atypical by a cytotechnologist and downgraded to benign by a pathologist: a measure of laboratory quality. (8/414)Follow-up of Papanicolaou (Pap) tests diagnosed as atypical squamous cells of undetermined significance (ASCUS) or atypical glandular cells of undetermined significance (AGUS) by a cytotechnologist and downgraded to benign by a pathologist has not been measured. Squamous intraepithelial lesion (SIL) follow-up rates were obtained for Pap tests diagnosed as ASCUS (288) or AGUS (94) and downgraded to benign and for Pap tests diagnosed as repair (231). Statistically significant associations were seen between 7 cytotechnologists and between 7 pathologists and ASCUS, AGUS, downgraded ASCUS, and downgraded AGUS rates. The percentage of downgraded ASCUS cases compared with all ASCUS cases per pathologist ranged from 4.8% to 43.7%. Statistically significant associations between pathologists and SIL follow-up rates for downgraded ASCUS diagnoses were seen. The SIL follow-up rate for repair (7.9%) was similar to that for a downgraded ASCUS (11.0%) or AGUS (7.3%). The parameters of downgraded ASCU and AGUS Pap test interpretations are good quality indicators of individual performance and overall laboratory quality. (+info)

Sunday « 58th Annual Scientific Meeting
Cytologists and cell biologists are both focused on cancer cells, yet there is very little cross-talk between these two fields. This session aims to create common ground through an in-depth description of the cell biology basis of cytologists criteria of malignancy. This session will be useful for cytologists who wish to collaborate or work in cancer research, and for educators who want to stay abreast of the rapid developments in research related to cytology. In addition to facilitating communication and collaboration, it is our experience that an understanding of the cell biology basis for morphologic changes helps reinforce a thorough understanding of the criteria of malignancy. This session therefore should have appeal for cytologists at all levels of experience-from beginners who want to learn or reinforce diagnostic concepts to senior cytologists who want to know the latest developments in the histone code or anoikis mechanisms. The session would also be useful for cell biologists who may ...

Cellular and Micro Biology - Seattle University
Because cell biologists seek to understand how cells function both under normal conditions and in disease states such as cancer, cystic fibrosis, diabetes and muscular dystrophy, the CDB emphasis constitutes a middle road for those planning medical careers. In addition to the standard techniques of biochemistry and molecular biology, cell biologists employ a powerful array of optical and physiological techniques to measure and manipulate the location and concentration of ions and molecules within living cells and subcellular organelles, and even the forces exerted by cells on their surroundings ...

Yeast becomes a cell biologist | JCB
The two went to Woods Hole to see if Bob and Anne Goldmans antibodies to mammalian cytoskeletal proteins would recognize yeast proteins. By chance, Kilmartin was there with his new monoclonal antitubulin antibody, which he had already managed to get into spheroplasts. The spheroplasts showed good IF, but had lost the original cells shape and organization. We decided to try to fix the cells before removing the cell wall, Adams recalls. It worked. It was exciting to see cytoplasmic microtubules in yeast that are hard to see by EM, but by IF they really stood out.. IF tools now in hand, Adams and Pringle returned to the University of Michigan (Ann Arbor, MI), and Kilmartin to the MRC Laboratory of Molecular Biology (Cambridge, UK) to delve further into the roles of actin and microtubules. Kilmartin examined actin by IF while Adams stained it with the newly available fluorescent phalloidin.. In two papers, they described the distribution of actin in cortical patches and cytoplasmic cables that ...

How Cell Biologists Work: Valentina Greco on cultivating a passionate research team - ASCB
I believe that as a society, we see heroes as individuals who are extremely bright and special, but who go solo and owe little to the majority of people around them. I believe we also perceive dependence on teamwork as a vulnerability instead of an enhancement of any single individual capacity to reach a goal. Thus, the quality I admire in my scientific heroes is the genuine recognition of their dependence on their team members as well as their projected perception that their incredible discoveries and (scientific) accomplishments are the result of an interdependent community.. What do you like to read, learn, or think about outside of lab?. I think a lot about biases and how they can affect my thinking and behaviors. I also love playing or listening to music and have Pandora to inform me of new bands/songs.. Are there any causes or initiatives in or outside of science that you are particularly passionate about?. Being both an immigrant and a woman I tend to think a lot about diversity. It has ...

The Cell Cycle and Division Laboratory of the Department of Biology, University of Crete is interested in understanding the mechanisms of cell cycle checkpoints triggered by DNA damage, inhibition of DNA replication and spindle poisons (Zachos et al, EMBOJ 22: 713-723, 2003- Zachos et al, Mol. Cell. Biol. 25: 563-574, 2005). Recently, we were the first to show that Chk1 protein kinase, a well-established component of the DNA damage checkpoint, is also required for the mitotic spindle checkpoint (Zachos et al, Dev Cell 12: 247-260, 2007). We are seeking a highly motivated and dedicated postdoctoral research scientist to further explore this novel role of Chk1 in mitosis by investigating ...
Research | Department of Cell Biology at Johns Hopkins University School of Medicine
Many adult tissues are renewed from small populations of stem cells, which continually replace differentiated cells lost to damage or age. Since tissue stem cells are highly dependent on signals from their local microenvironments, or niches, understanding how niches work is important for manipulating regeneration. To answer this question, the Matunis lab combines genetics, live imaging, and genome-wide approaches to understand how the germline and somatic cells in the testis that create and reside in the testis niche cooperatively ensure a lifetime supply of sperm. ...
Computational cell biology at the home of the helix | EMBO Reports
An area that has seen the successful integration of theory and experiment is the cell cycle. Many of the discoveries in cell‐cycle research have been made by studying unicellular yeast species in which the cell cycle is controlled by a complex network that integrates signals both from within the cell and from the surrounding environment. The giant African frog Xenopus laevis, which lacks genetics tools and must choreograph mitosis with the development of a metazoan body plan, would at first glance appear to be an unpromising organism for gaining quantitative insight into the cell cycle. However, it is in this system that Ferrell and colleagues have produced fascinating work on the key components of the eukaryotic cell‐cycle network.. A feature of X. laevis that makes it particularly amenable to quantitative studies is that the first 12 cleavages of the early embryo occur synchronously and at regular intervals of around half an hour. These blastomere cells seem to lack most, if not all, of ...

VIDEO: Newly discovered form of cell division may help ward off cancer : Spoonful of Medicine
Cell biologists have long thought that cytokinesis, the final step of cell division in which the cytoplasm and its contents are split, is necessary for the proper assortment of chromosomes. Disrupt this process, the prevailing wisdom held, and aneuploidy will result, with cancerous implications. But a team led by Mark Burkard at the University of Wisconsin-Madison has discovered a new type of cell division, dubbed klerokinesis, that protects cells from failed cytokinesis.. Using live-cell imaging, the researchers watched retinal pigment epithelial cells for five days after they had chemically inhibited cytokinesis. Reporting today at the American Society for Cell Biologys annual meeting in San Francisco, they showed that many cells managed to split into two during the first growth phase of the next cell cycle-not during mitosis-allowing each to recover a normal chromosome set. Burkard says that therapeutic strategies that boost this type of nonmitotic cell fission could prevent cancer in ...

Learning biology | Statistical Biophysics Blog
Youre a quantitative person and you want to learn biology. My friend, you are in a difficult situation. If you really want to learn how biology works in a big-picture sense, as opposed to cutting yourself a very narrow slice of the great biological pie, then you have a challenging road ahead of you. Fortunately, many have walked it before you, and I want to give you some advice based on my own experiences. I should say at the outset that my own learning has focused mostly on the cell-biology part of the pie - not physiology, zoology, ecology, … and so my comments here refer to learning cell biology.. The scary thing is that I have been at this for almost 20 years (very part-time admittedly) and I would never dare to call myself a cell biologist. But I think its fair to say that by now I have a decent sense of what I know and what I dont know. I will never be able to draw out the Krebs cycle, but I have a qualitative sense of its purpose and importance, as well as of general principles of ...

Beyond the Identification of Transcribed Sequences: Functional and Expression Analysis
2Institute of Protein Research, Russian Academy of Sciences, Pushchino, Russia. Alternative splicing is an important regulatory mechanism in higher eukaryotes. By recent estimates, at least 30% of human genes are spliced alternatively (1). Alternative splicing plays a major role in sex determination in Drosophila, antibody response in humans and other tissue or developmental stage specific processes. The database of alternatively spliced genes can be of potential use for molecular biologists studying splicing, developmental biologists, geneticists, and cell biologists. We have created a public Alternative Splicing Database (ASDB) (2) for the biological community as a repository of data on alternatively spliced genes. ASDB is currently available at the URL http://hazelton.lbl.gov/~teplitski/alt/. The administrator of the database can be contacted by Email: [email protected] Our original set of 1663 proteins was generated by selecting all SwissProt entries containing the words alternative splicing. ...

Spinning-disk microscope offers window into the center of a cell
A new method of imaging cells is allowing scientists to see tiny structures inside the control centre of the cell for the first time.. The microscopic technique, developed by researchers at Queen Mary University of London, represents a major advance for cell biologists as it will allow them to investigate structures deep inside the cell, such as viruses, bacteria and parts of the nucleus in depth.. Recent advances in optical physics have made it possible to use fluorescent microscopy to study complex structures smaller than 200 nanometres (nm) - around 500 times smaller than the width of a human hair. These methodologies are called super-resolution microscopy.. The drawback of such techniques is that they can only produce very clear images of structures that are at the bottom of the cell. Since the nucleus - the cells control centre - is in the middle of the cell and bacterial and viral infections can happen anywhere in the cell, this technique has considerable limitations for ...

August 2016 - Weeding the Gems
The conference opened with a key note lecture delivered by Professor Jen Sheen, who began in contrast to the typical fashion of justifying why plant science is important, by displaying some of her own craftsmanship of photography and horticulture, to instead remind us how diverse and beautiful plants really are. Professor Sheen has spent much of her career delving into the world of how sugars, mainly glucose and also nitrates, act as a signalling molecules in plants. Dissecting this process is truly an interesting topic for a cell biologist, these processes are important to organisms at a multitude of levels, and critically they are not static, and are among a tangle of interconnections. Professor Sheens description of these processes made for an excellent talk at the cutting edge of molecular biology.. In organellar biology I was excited to meet Dr. Jesse Woodson, who presented the findings of his recent Science paper (Woodson JD, et al. 2015. Science 350:450-4) together with some previously ...

This perspective tackles the issues facing developmental biologists and cell biologists regarding how the molecular mechanisms for specifying cell fate are defined. This perspective focuses on members of the Wnt family. The author proposes that Wnt proteins may act as stabilizing signals for earlier inductive events in certain systems, for example, in Caenorhabditis elegans during the migration of two neurons and in Drosophila melanogaster during the patterning of the wing.

It has been unclear thus far how the two bacterial effectors Tir and EspFU enter into contact with one another in the host cell, says Theresia Stradal. Her research group has now found the missing link: The molecule comes from the host cell, is called IRSp53 and gathers on the cell surface, directly beneath the bacteria sitting on it, explains cell biologist Markus Ladwein, who is also involved in the project. IRSp53, then, establishes the connection between Tir and EspFU. It ensures that actin conversion is concentrated locally. Together with the biochemist Dr. Stefanie Weiß, a former post-graduate student with the research group, Markus Ladwein also provided the counter evidence: Cells in which IRSp53 is lacking are no longer able to form pedestals for the bacteria ...
Anniversary paper on Billingham (1956) | Philosophical Transactions of the Royal Society B: Biological Sciences
At NIMR Medawar turned his attention to investigating the immunosuppressive qualities of ALS, as mentioned in the previous section. He encouraged and supported scientists at the Institute and recruited an additional number working in disciplines caught up in the spin-out of immunological ideas and questions. It was a heady time. I joined at the end of 1968, and started collaborative experiments contributing to the definition of phenotypically and functionally different subpopulations of T cells [39-41]. I was caught up in the ferment in which microbiologists, cell biologists, physiologists, biochemists, as well as research clinicians in various specialities, moved in and out of each others laboratories talking about ideas and results. These conversations continued during lunch and coffee breaks, and in the bar at the end of the day. I was encouraged to try new in vitro approaches to cell-mediated immunity. I went to the National Institutes of Health (NIH) where I gained experience of growing ...
VR app gives students a new way to see inner workings of cells | Folio
An educational app created at the University of Alberta is giving cell biology students a brand new perspective on their subject and may also offer a glimpse into the not-so-distant future of post-secondary education.. The Cell 101 VR App shows students a virtual reality perspective of the inner workings of cells and their interactions, allowing them to visualize cell biology in a way they never could before.. Everything that cells do is because of their internal machinery, but how this machinery is constructed from proteins and other biomolecules is very hard for students to conceptualize, said Paul LaPointe, an associate professor of cell biology at the U of A who helped create the application. He said its a difficult concept to illustrate and contextualize, making it difficult for students to understand that when a drug does something in the cell, its because it fits in the recesses of the proteins inside, preventing them from taking a mechanical action. If you can tap into their ...

Quantification of Cell Edge Velocities and Traction Forces Reveals Distinct Motility Modules during Cell Spreading | Academic...
Actin-based cell motility and force generation are central to immune response, tissue development, and cancer metastasis, and understanding actin cytoskeleton regulation is a major goal of cell biologists. Cell spreading is a commonly used model system for motility experiments - spreading fibroblasts exhibit stereotypic, spatially-isotropic edge dynamics during a reproducible sequence of functional phases: 1) During early spreading, cells form initial contacts with the surface. 2) The middle spreading phase exhibits rapidly increasing attachment area. 3) Late spreading is characterized by periodic contractions and stable adhesions formation. While differences in cytoskeletal regulation between phases are known, a global analysis of the spatial and temporal coordination of motility and force generation is missing. Implementing improved algorithms for analyzing edge dynamics over the entire cell periphery, we observed that a single domain of homogeneous cytoskeletal dynamics dominated each of the three

UAB - Magazine - UAB Magazine Online Features
In cell biology, as in love, you often dont know what youve got till its gone. For more than a century, scientists have known that most cells in the human body come equipped with an odd projection on their outer surfaces called the primary cilium. Unlike the wavy, hairlike cilia you may remember from biology class-the ones that sweep mucus out of the airways-the primary cilia are rigid and didnt seem to have any useful function. They were written off as vestigial, like tonsils or the appendix.. But 10 years ago, a handful of cell biologists including UABs Bradley Yoder, Ph.D., began to unravel the secrets of this obscure organelle. Starting in green algae and only lately moving up to humans, they made a startling discovery: If a cell loses its cilium, bad things begin to happen. Their investigations have revealed that, far from being an artifact, the primary cilium is actually an important communications device-and a major player in human growth and development, kidney disease, obesity, ...

ECHO, the executable CHOndrocyte - Research - Aarhus University
Computational modeling can be used to investigate complex signaling networks in biology. However, most modeling tools are not suitable for molecular cell biologists with little background in mathematics. We have built a visual-based modeling tool for the investigation of dynamic networks. Here, we describe the development of computational models of cartilage development and osteoarthritis, in which a panel of relevant signaling pathways are integrated. In silico experiments give insight in the role of each of the pathway components and reveal which perturbations may deregulate the basal healthy state of cells and tissues. We used a previously developed computational modeling tool Analysis of Networks with Interactive Modeling (ANIMO) to generate an activity network integrating 7 signal transduction pathways resulting in a network containing over 50 nodes and 200 interactions. We performed in silico experiments to characterize molecular mechanisms of cell fate decisions. The model was used to ...

Image analysis in fluorescence microscopy: bacterial dynamics as a case study. | Lewis-Sigler Institute
Fluorescence microscopy is the primary tool for studying complex processes inside individual living cells. Technical advances in both molecular biology and microscopy have made it possible to image cells from many genetic and environmental backgrounds. These images contain a vast amount of information, which is often hidden behind various sources of noise, convoluted with other information and stochastic in nature. Accessing the desired biological information therefore requires new tools of computational image analysis and modeling. Here, we review some of the recent advances in computational analysis of images obtained from fluorescence microscopy, focusing on bacterial systems. We emphasize techniques that are readily available to molecular and cell biologists but also point out examples where problem-specific image analyses are necessary. Thus, image analysis is not only a toolkit to be applied to new images but also an integral part of the design and implementation of a microscopy experiment. ...

Researchers Recreate Genetic Disorder In The Lab - Redorbit
When neurons started dying in Clive Svendsens lab dishes, he couldnt have been more pleased.. The dying cells the same type lost in patients with the devastating neurological disease spinal muscular atrophy confirmed that the University of Wisconsin-Madison stem cell biologist had recreated the hallmarks of a genetic disorder in the lab, using stem cells derived from a patient. By allowing scientists the unparalleled opportunity to watch the course of a disease unfold in a lab dish, the work marks an enormous step forward in being able to study and develop new therapies for genetic diseases.. As reported this week in the journal Nature, Svendsen and colleagues at UW-Madison and the University of Missouri-Columbia created disease-specific stem cells by genetically reprogramming skin cells from a patient with spinal muscular atrophy, or SMA. In this inherited disease, the most common genetic cause of infant mortality, a mutation leads to the death of the nerves that control skeletal ...

Monolithic PDMS passband filters for fluorescence detection
Many areas of biological research increasingly perform large-scale analyses. In genomics the entire gene repertoire of an organism is analyzed. Proteomics attempts to understand the function and expression patterns of all proteins in a cell or organism. Cell biologists study large numbers of single cells to understand the heterogeneity of cell populations. In biotechnology and synthetic biology researchers search for new functional biomolecules in large libraries of biomolecular diversity e.g. for uses in medicine or bioprocessing. More and more all of these fields employ high throughput methods to achieve the scale of analysis necessary.. Miniaturization and parallelization provide routes towards high throughput analysis, which have proven successful for microelectronics as well as for DNA sequencing. For the analysis of cells and biomolecules, native to an aqueous environment, miniaturization and parallelization hinges on the handling and parallel processing of very small amounts of water. ...

The Mini Lungs and Other Organoids Helping to Beat COVID - - Medtelligence
Photo: Salahudeen, A. A. nature.com Shuibing Chen spent close to two months tending to her mini lungs — some half a million of them. Each one looked like a tiny storm cloud, ensconced in a warm dish and protected by a jelly-like dome. Chen, a stem-cell biologist at Weill Cornell Medicine in New York City, and her team had nurtured them from clumps of human cells, adding nutrients every few days as they grew into 3D air sacs. These lung organoids matured until they reached the size of a lentil. Then, the team packed them up and transported them just a few blocks away, to a laboratory authorized to work with SARS-CoV-2, the virus responsible for the COVID-19 pandemic. There, the organoids were drowned in virus and each was doused with one of 15,000 drugs. Almost all of the mini lungs died, but a few of the drugs stemmed from the infection — representing a handful of possible treatments for COVID-19. Chen is one of many cell biologists who have been driven by the pandemic to push the boundaries

AANS Neurosurgeon Mice on Wheels Show Scientists How Exercise Benefits Their Brains - AANS Neurosurgeon
Running rodents make more of a Miracle-Gro chemical for the brain. A protein called brain-derived neurotrophic factor, or BDNF, has been labeled as the Miracle-Gro protein in the brain based on its role in enhancing memory and the growth of nerve cells. Researchers found in a study using mice that BDNF levels increase within the brain when the mice exercise on the wheel. We believe that our study shows a precise biological mechanism behind increased BDNF production in mammals due to exercise, says study senior investigator and cell biologist Moses Chao, PhD. Unraveling the mysteries of BDNF is important as we seek more ways to naturally keep mammalian brains healthy, including those or people, said Chao, a professor at NYU Langone and its Skirball Institute of Biomolecular Medicine.

A simple and accurate rule-based modeling framework for simulation of autocrine/paracrine stimulation of glioblastoma cell...
Glioblastoma multiforme (GBM) is a devastating brain cancer for which there is no known cure. Its malignancy is due to rapid cell division along with high motility and invasiveness of cells into the brain tissue. Simple 2-dimensional laboratory assays (e.g., a scratch assay) commonly are used to measure the effects of various experimental perturbations, such as treatment with chemical inhibitors. Several mathematical models have been developed to aid the understanding of the motile behavior and proliferation of GBM cells. However, many are mathematically complicated, look at multiple interdependent phenomena, and/or use modeling software not freely available to the research community. These attributes make the adoption of models and simulations of even simple 2-dimensional cell behavior an uncommon practice by cancer cell biologists. Herein, we developed an accurate, yet simple, rule-based modeling framework to describe the in vitro behavior of GBM cells that are stimulated by the L1CAM protein using

We seek to develop new approaches to manipulate and assay processes in living cells, using microscopy, genetics, and micro-fabricated devices ...
Under the skin and out in the world
When Fuchs started working on skin-derived stem cells during the fields nascency in 1978, the cells went by a different name.. Human epidermal keratinocytes. A very boring name, she said. We now, of course, know that virtually every tissue of our body has long-lived stem cells that are able to regenerate tissue, both to repair dying cells and also to repair wounds, so its virtually a universal property of the tissues of our body. But back then, there was very little known about it.. At that time, Fuchs was a postdoctoral fellow at the Massachusetts Institute of Technology in the lab of Howard Green, a cell biologist who pioneered skin grafting by growing human cells in culture. When Fuchs was a graduate student at Princeton working on bacterial sporulation, she had attended a guest seminar by Green about culturing cells from human skin.. I just immediately thought, Thats what I want to work on for my postdoctoral work, Fuchs said. It was at the time where a few people were starting ...

Systematics (ref. ID; 4926)
The Infusoria or Ciliophora, as they are now called have long been recognized as a monophyletic assemblages. The composition of the group has remained largely unchanged since Faure-Fremiet (1950) included among holotrich ciliates, the suctorians, which had often not been included with the other ciliates by the specialists of the day (Corliss 1979). The classification of the group remained largely unchanged in the 20th century after Corliss (1961) formalized Faure-Fremiets conceptual vision, based primarily on the morphostatic morphology of the cells, derived from observation of the silver-stained ciliate cortex, and coupled with ontogenetic characters revealed through observation of division morphogenesis, and particularly stomatogenesis. Electron microscopy was just beginning as Corliss (1961) went to press. In the ensuing decades exploration of this new level of organization revealed a wealth of new characters for both cell biologists and systematists. These new data, accompanied by new ...
Mind Your Head!: What Makes You Uniquely You?
A physician and cell biologist who won a 1972 Nobel Prize for his work describing the structure of antibodies, Edelman is now obsessed with the enigma of human consciousness-except that he does not see it as an enigma. In Edelmans grand theory of the mind, consciousness is a biological phenomenon and the brain develops through a process similar to natural selection. Neurons proliferate and form connections in infancy; then experience weeds out the useless from the useful, molding the adult brain in sync with its environment. Edelman first put this model on paper in the Zurich airport in 1977 as he was killing time waiting for a flight. Since then he has written eight books on the subject, the most recent being Second Nature: Brain Science and Human Knowledge. He is chairman of neurobiology at the Scripps Research Institute in San Diego and the founder and director of the Neurosciences Institute, a research center in La Jolla, California, dedicated to unconventional high risk, high payoff ...
Myocyte - Wikipedia
Individual muscles tend to be a mixture of various fiber types, but their proportions vary depending on the actions of that muscle and the species. For instance, in humans, the quadriceps muscles contain ~52% type I fibers, while the soleus is ~80% type I. The orbicularis oculi muscle of the eye is only ~15% type I. Motor units within the muscle, however, have minimal variation between the fibers of that unit. It is this fact that makes the size principal of motor unit recruitment viable. The total number of skeletal muscle fibers has traditionally been thought not to change. It is believed there are no sex or age differences in fiber distribution; however, proportions of fiber types vary considerably from muscle to muscle and person to person. Sedentary men and women (as well as young children) have 45% type II and 55% type I fibers. People at the higher end of any sport tend to demonstrate patterns of fiber distribution e.g. endurance athletes show a higher level of ...
Immune cells gobble out-of-control fibroblasts when dont-eat-me signal is blocked - Scope
Idiopathic pulmonary fibrosis, scleroderma and liver cirrhosis are just a few of a pantheon of confusingly named, difficult-to-treat and sometimes life-threatening diseases caused by the malfunction of a single cell type. But until now its not been clear whether the disorders shared a deeper root cause.. Now Stanford pathologist Gerlinde Wernig, MD, and stem cell biologist Irving Weissman, MD, have identified a cell signaling pathway that, when mutated, causes widespread fibrosis in laboratory mice. Whats more, they showed that an antibody currently in trials as an anti-cancer treatment can reverse the condition. They published their results this week in the Proceedings of the National Academies of Science.. From our release:. ...
Wear your science - or a cross-section of it - bioephemera
So I had the pleasure of meeting the awesome Dr. Isis a few weeks ago. It turns out she is even more awesome in person than she is in pseudonymity. And she brought me a fabulous thing: a scarf from A Slice of Life Scarves. Creator Eve Reaven, a Bay Area cell biologist, has continuously marveled at the intricacy and beauty of the natural patterns found inside cells. She shares what she has seen with others through designs for scarves and other textiles. In the current selection, she captures the essence of structures related to cell movement, cell traffic, energy and performance. Many of the cell structures represented in these patterns are magnified 50,000 to 1,000,000 times their original size, allowing us to experience the amazing designs created by nature. It doesnt really sound that attractive - honestly, when I think of microtomes, I always think of a horrifically bloody accident I saw as an undergrad - but the patterns are gorgeous. I was wearing gray (which is very big this year), so I ...
