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.

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)

Prototype Web-based continuing medical education using FlashPix images. (5/414)

Continuing Medical Education (CME) is a requirement among practicing physicians to promote continuous enhancement of clinical knowledge to reflect new developments in medical care. Previous research has harnessed the Web to disseminate complete pathology CME case studies including history, images, diagnoses, and discussions to the medical community. Users submit real-time diagnoses and receive instantaneous feedback, eliminating the need for hard copies of case material and case evaluation forms. This project extends the Web-based CME paradigm with the incorporation of multi-resolution FlashPix images and an intuitive, interactive user interface. The FlashPix file format combines a high-resolution version of an image with a hierarchy of several lower resolution copies, providing real-time magnification via a single image file. The Web interface was designed specifically to simulate microscopic analysis, using the latest Javascript, Java and Common Gateway Interface tools. As the project progresses to the evaluation stage, it is hoped that this active learning format will provide a practical and efficacious environment for continuing medical education with additional application potential in classroom demonstrations, proficiency testing, and telepathology. Using Microsoft Internet Explorer 4.0 and above, the working prototype Web-based CME environment is accessible at http://telepathology.upmc.edu/WebInterface/NewInterface/welcome.html.  (+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.  (+info)

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)

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 ...

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 ...
Box 1. Determining the quality of a TIRF set up. The test samples described below can be used to check the quality of any TIRF set up. They should always be prepared using a cover slip with the correct thickness and refractive index for the objective.. Test samples. Fluorescent microbeads. These can be purchased from many sources, including Invitrogen (Carlsbad, CA) and Bangs Laboratories (Fishers, IN). The beads should be of subresolution size (100 nm diameter or less), and selected to have excitation and emission spectra that match typical experimental conditions. The beads should be diluted in water and applied to the cover slip. PBS can be added to increase the number of beads that adhere to the surface.. DiI. A convenient, uniform, fluorescent film can be easily made on a cover slip surface with the lipophilic fluorophore DiI (Invitrogen, Carlsbad, CA). Dissolve the DiI at 0.5 mg/ml in ethanol and place a single droplet of the solution on a glass cover slip. Then, before the solution dries, ...
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 ...

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 ...

Originally From: George Zachos ,gzachos at biology.uoc.gr, Job Vacancy: Postdoctoral Research Scientist Genetic and molecular analysis of Chk1 functions in the mitotic spindle checkpoint and cytokinesis Prof George Zachos Starting date: 1 October 2008. 3-year fixed-term contract. Salary will depend on experience. 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 ...
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 ...

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 ...

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 ...

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". ...
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 ...

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 ...
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 ...

PHILADELPHIA (October 3, 2019) - Newly discovered chemical-sensing cells in the gums protect the mouth by standing guard against infections that damage soft tissue and destroy the bone that supports the teeth, report researchers from the Monell Chemical Senses Center in an animal study published this week in Nature Communications. With the help of bitter taste receptors that also detect byproducts from harmful bacteria, these special gum cells trigger the immune system to control the amount and type of bacteria in the mouth and could one day lead to personalized dental treatments against gum disease. Periodontitis is a serious gum disorder induced by an imbalance in the bacteria and other microorganisms of the mouth (the oral microbiome). It is the sixth-most prevalent infectious disease and the most common cause of tooth loss worldwide. Monell Center Director and President Robert Margolskee, MD, PhD and cell biologist Marco Tizzano, PhD, along with colleagues from Sichuan University, found that ...
Organs-on-Chip - Mimicking the in-vivo cellular microenvironment During more than 100 years cell biologists have been culturing cells on flat and hard substrates, called Petri dishes. Plastics replaced glass, but the plates Julius Richard Petri invented in 1887 havent changed and are still widely used today. Although an instrumental tool for life-saving medical breakthroughs, like Sir Alexander Flemings discovery of penicillin, the in-vitro environment provided by Petri dishes widely differs from the native environments the cells are accustomed to in the body. As a result, they often lose their original functions and are no longer suitable to be used as models to test for instance drug candidates. The pharmaceutical industry increasingly recognized this fact and turns more and more to new in-vitro models, such as organs-on-chip, that more accurately represent the milieu in the human body. Organs-on-chip are advanced in-vitro models that mimic the smallest functional unit of an organ. These ...
Content MathML is the part of the language particularly concerned with the semantics of the constructs of mathematics. For that reason it has appealed to other scientific communities engaged in semantic markup for their disciplines. For example, it is currently incorporated by reference as a part of CML (Chemical Markup Language) for chemistry and CellML for molecular and cell biologists. In addition it has proved attractive to the e-learning community. In its current form, Content MathML comprises about 120 elements taking about a dozen attributes. It is planned to add about ten new elements that for completeness in the fundamental areas of mathematical usage, particularly in connection with statistics.. One of the intended strengths of Content MathML was to be the extension mechanism it provided for introduction of new specialized notations, which are being developed all the time. An important, long-standing and well-developed approach to formal specification of the meaning of mathematics is ...
16.07.2013 Researchers at Johannes Gutenberg University Mainz (JGU) have discovered a new form of communication between different cell types in the brain. Nerve cells interact with neighboring glial cells, which results in a transfer of protein and genetic information. Nerve cells are thus protected against stressful growth conditions. The study undertaken by the Mainz-based cell biologists shows how reciprocal communication between the different cell types contributes to neuronal integrity. Their results have been recently published in the journal PLOS Biology. Brain function is determined by the communication between electrically excitable neurons and the surrounding glial cells, which perform many tasks in the brain. Oligodendrocytes are a type of glial cell and these form an insulating myelin sheath around the axons of neurons. In addition to providing this protective insulation, oligodendrocytes also help sustain neurons in other ways that are not yet fully understood. If this support ...
lines differ from cell strains in that they have escaped the Hayflick limit and become immortalised. Some species, particularly rodents, give rise to lines relatively easily, whereas other species do not. No cell lines have been produced from avian tissues and the establishment of cell lines from human tissue is difficult. Many cell biologists would consider that a cell line is by definition already abnormal and that it is on the way towards becoming the culture equivalent of a neoplastic cell. ...

This popular book, written by a biochemist and cell biologist, got its start when Gottschalls daughter was diagnosed with Crohns Disease at a young age. She developed the Specific Carbohydrate Diet, a strict grain-free, lactose-free, and sucrose-free regimen, as an alternative to medication and surgery. The diet is intended to starve anaerobic bacteria in the intestinal tract, similar to the use of antibiotics for Crohns. No clinical trials have been conducted on its effectiveness for IBD as far as I know, but if you are looking for alternative approaches you might try this dietary approach.. ...

Chiara Zurzolo, MD PhD, is head of the Membrane Trafficking and Pathogenesis Unit and head of the Department of Cell Biology and Infection.. In 1995, started her lab as professor of Cell Biology at Naples University Federico II, where she graduated, focusing on protein trafficking and specifically on the mechanisms of apical sorting of GPI-proteins (GPI-AP) in polarized epithelia. In 2003 she moved to the Pasteur Institute where she pioniered studies on the role of protein trafficking in prion diseases. She has made seminal discoveries in both protein trafficking and neurodegeneration. Her group has shown that the mechanism of sorting of GPI-APs (cholesterol dependent oligomerization) in the Golgi of polarized cells controls the protein function at the apical plasma membrane (2008, 2014). They uncovered the intracellular site of prion conversion and showed that prion dissemination occurs by Tunneling Nanotubes, a new mechanisms of direct intercellular communication (2009). She proposes that TNTs ...

In a beautifully orchestrated chain of events that is fundamental to life and health, our bodies continually undergo mitosis-a process by which a "parent" cell divides, producing two identical "daughter" cells, which in turn also divide, and so on. When we are in good health, mitosis is carefully regulated to ensure fidelity and allows new cells to be produced as needed for both growth and repair of aging or damaged tissues.. But when genetic mutations occur, they can lead to unchecked cell growth and proliferation-a hallmark of many cancers and birth defects. Understanding the molecular mechanisms that underlie these changes is the work of Arminja Kettenbach, PhD, an assistant professor of Biochemistry and Cell Biology at the Geisel School of Medicine.. In the following Q&A, Kettenbach talks about two high-profile grant awards that she recently received, and the focus of the Kettenbach Lab, located in Dartmouth-Hitchcocks Norris Cotton Cancer Center.. Q: Can you tell us about the two grants ...

The first and most obvious use would be to develop a therapy that signals myofibroblasts to convert into adipocytes - helping wounds heal without scarring.. "Its highly desirable from a clinical standpoint, but right now its an unmet need," Cotsarelis said.. But the increase of fat cells in tissue can also be helpful for more than just wounds. Adipocyte loss is a common complication of other conditions, especially treatments for HIV, and right now there is no ...
I am programme director for anatomy at the University of Liverpool. My research is centred on understanding the development and evolution of the vertebrate nervous system. In particular, we work on the cerebellum, on sensory neurons, and on adult neurogenesis. Deep in the annals of evolutionary history, I read Cell Biology at the University of Durham and subsequently received my PhD from the University of Oxford in the evolution of homeobox genes in animals. Following this, I moved to Kings College, London where my interest in the nervous system was honed, and before Liverpool was a lecturer in neurobiology at Queen Mary, University of London ...
Author: press release provided by University of Connecticut. Modern genetic testing can predict your risk of contracting particular diseases based on predispositions discovered in your DNA. But what if similar biotechnology could tell you that youve got a disease before you notice any symptoms? What if it could even tell you, before any signs of a tumor, that you have cancer?. Jim Rusling, professor of chemistry at UConn and professor of cell biology at the UConn Health Center, ponders these questions on a daily basis. Since 2006, he and colleagues at the University and the National Institutes of Health (NIH) have been developing techniques to detect biomarker proteins - the physiological traits that indicate that a person has a specific disease - for prostate and oral cancer. Because these biomarkers are often present in the blood in a diseases early stages, they can be used for early detection and prevention.. "DNA predicts which proteins can be made, but it cant predict which proteins are ...

Differences between cells in different species - posted in Cell Biology: Hi guys Im no biologist, so Im sorry if these questions sound stupid. But I was wondering what are the differences between cells from different species ? For example, I have fibroblasts or osteoblasts from human and from mice. How are they different from each other ? The same question goes to proteins. If I have fibronectin from human, how is it different from bovine fibronectin ?

A major step in the development of the vertebrate embryo - the establishment of a back that morphs into a brain, spinal cord and muscles - turns out to be so important that the body uses at least three signals to make sure it happens properly. The discovery, reported this month in the journal Developmental Cell by researchers at the University of California, Berkeley, finally explains an 80-year-old observation that revolutionized the way biologists think about embryonic and fetal development and set the stage for the stem cell debate. ...

Well, this week has been rather unmotivated. I dont really feel that I have done a lot. But the thing about my work is that all I need to do is spend a couple of hours on the electron microscope and already I have a brand new, never been seen before result. And I at least think that my work and results are very interesting and even rather exciting so I would like to share such things. Which is a little pointless as many people know nothing of cells and their features. So today I am going to explain for you, very briefly, what this all means, so that I can show you some of my beautiful micrographs (aka photos taken with the microscope - see you are learning already!) If you do not need to be given an incredibly simple tutorial of a cell, why not just look at all my pretty pictures ...

Dear friends, collaborators, relatives and other potential partners in my misery, HEEEELP! My apologies for bugging all of you with this, but I assume that many of you might have gone through pains I am just about to experience. Hence, my hope that you may be able, and willing, to help. Thank you in advance. I will be putting together a LABORATORY cell biology course for 3rd, preferably 4th year undergraduate students. I expect a class of in between 30 and MAXIMUM 50 students. I would appreciate suggestions on what type experiments one can design for such a class? I would prefer students DO experiments and not WATCH them being done. I presume that the class could be split into three groups if such need arises. We have at hand two c-focal microscopes, four wide-field fluorescence microscopes, and quite a number of standard student-type bright field microscopes. Of course, the experiments do not have to be restricted to microscopy, a simple, student-performed dissctions followed by tissue culture, ...

Gestational trophoblastic disease (GTD) is a term used for a group of pregnancy-related tumours. These tumours are rare, and they appear when cells in the womb start to proliferate uncontrollably. The cells that form gestational trophoblastic tumours are called trophoblasts and come from tissue that grows to form the placenta during pregnancy. There are several different types of GTD. Hydatidiform moles are benign in most cases, but sometimes may develop into invasive moles, or, in rare cases, into choriocarcinoma, which is likely to spread quickly, but which is very sensitive to chemotherapy, and has a very good prognosis. Gestational trophoblasts are of particular interest to cell biologists because, like cancer, these cells invade tissue (the uterus), but unlike cancer, they sometimes "know" when to stop.[citation needed] GTD can simulate pregnancy, because the uterus may contain fetal tissue, albeit abnormal. This tissue may grow at the same rate as a normal pregnancy, and produces chorionic ...

  • Eukaryotic cells include animal, plant, fungi, and protozoa cells which all have a nucleus enclosed by a membrane, with various shapes and sizes. (wikipedia.org)
  • The main constituents of the general molecular composition of the cell includes: proteins and lipids which are either free flowing or membrane bound, along with different internal compartments known as organelles . (wikipedia.org)
  • The cell membrane consists of lipids and proteins and is selectively permeable . (google.com)
  • The hydrophilic regions of the cell are mainly on the inside and outside of the cell, while the hydrophobic regions are within the phospholipid bilayer of the cell membrane. (wikipedia.org)
  • The cell membrane consists of lipids and proteins, which accounts for its hydrophobicity as a result of being non-polar substances. (wikipedia.org)
  • Therefore, in order for these molecules to participate in reactions, within the cell, they need to be able to cross this membrane layer to get into the cell. (wikipedia.org)
  • They accomplish this process of gaining access to the cell via: osmotic pressure, diffusion, concentration gradients, and membrane channels. (wikipedia.org)
  • Inside of the cell are extensive internal sub-cellular membrane-bounded compartments called organelles. (wikipedia.org)
