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.

Angiotensin II increases the release of endothelin-1 from human cultured endothelial cells but does not regulate its circulating levels. (1/8613)

We investigated the effect of angiotensin II on endothelin-1 secretion in vitro and in vivo. In vivo, angiotensin II was given intravenously to 23 essential hypertensive and 8 control subjects according to different protocols: Study A, 1.0 ng x min-1 x kg-1 and 3.0 ng x min-1 x kg-1 angiotensin II for 30 min each; Study B, 1.0 ng x min-1 x kg-1 and 3.0 ng x min-1 x kg-1 angiotensin II for 120 min each; Study C, 3.0 ng x min-1 x kg-1 angiotensin II for 30 min followed by a dose increment of 3.0 ng x min-1 x kg-1 every 30 min until mean blood pressure levels increased by 25 mmHg; Study D, 1.0 ng x min-1 x kg-1 followed by 3.0 ng x min-1 x kg-1 angiotensin II for 60 min each on two different NaCl diets (either 20 mmol NaCl/day or 220 mmol NaCl/day, both for 1 week). In all in vivo studies neither plasma nor urine endothelin-1 levels changed with angiotensin II infusion. In contrast, angiotensin II (10(-9), 10(-8), 10(-7) mol/l) stimulated endothelin-1 secretion from cultured human vascular endothelial cells derived from umbilical cord veins in a time- and dose-dependent manner. The in vitro angiotensin II effects were abolished by candesartan cilexetil, an inhibitor of the membrane-bound AT1 receptor, and also by actinomycin D, an RNA synthesis inhibitor, and cycloheximide, a protein synthesis inhibitor, indicating that endothelin-1 release depended on AT1 receptor subtype and de novo protein synthesis. Our findings indicate that angiotensin II regulates endothelin-1 release by cultured endothelial cells through an AT1 receptor-dependent pathway, but does not influence circulating endothelin-1 levels in vivo.  (+info)

A technique for dual determination of cytotoxic and helper lymphocyte precursor frequency by a miniaturized dye release method. (2/8613)

Helper (HTLPf) and cytotoxic (CTLPf) lymphocyte precursor frequency assays are increasingly used in bone marrow stem cell and organ transplant compatibility testing. Current techniques require large cell numbers and radioisotopes. To improve the technique, we developed a miniaturized fluorescent read-out combined HTLPf/CTLPf limiting dilution assay. The assay requires only 5 x 10(6) stimulators, 2 x 10(6) responders and 0.24 x 10(6) target cells in Terasaki plates (40 microl/well). For the HTLPf, culture supernatants from each well were assayed for IL-2 production. The IL-2-dependent proliferation of the mouse 9.12 cell line was detected by a semi-automated fluorescent dye technique. After addition of rhIL-2 (recombinant human IL-2) on days 3 and 7, CTLPs were detected on day 10 by measuring the lysis of dye-labeled targets. Results were comparable to standard radioisotope-based techniques. The assay had a coefficient of variation of approximately 30%. The assay detected helper CD4 cells, pure cytotoxic CD8, helper CD8 cells and helper/cytotoxic CD8 cells. Discrimination was demonstrated between HLA-matched related and non-related pairs. The ease of testing and small cell numbers required should facilitate further evaluation of HTLPf and CTLPf for compatibility testing in unrelated donor transplantation and monitoring immune responses following adoptive transfer of lymphocytes.  (+info)

Generation and characterization of aggrecanase. A soluble, cartilage-derived aggrecan-degrading activity. (3/8613)

A method was developed for generating soluble, active "aggrecanase" in conditioned media from interleukin-1-stimulated bovine nasal cartilage cultures. Using bovine nasal cartilage conditioned media as a source of the aggrecanase enzyme, an enzymatic assay was established employing purified aggrecan monomers as a substrate and monitoring specific aggrecanase-mediated cleavage products by Western analysis using the monoclonal antibody, BC-3 (which recognizes the new N terminus, ARGS, on fragments produced by cleavage between amino acid residues Glu373 and Ala374). Using this assay we have characterized cartilage aggrecanase with respect to assay kinetics, pH and salt optima, heat sensitivity, and stability upon storage. Aggrecanase activity was inhibited by the metalloprotease inhibitor, EDTA, while a panel of inhibitors of serine, cysteine, and aspartic proteinases had no effect, suggesting that aggrecanase is a metalloproteinase. Sensitivity to known matrix metalloproteinase inhibitors as well as to the endogenous tissue inhibitor of metalloproteinases, TIMP-1, further support the notion that aggrecanase is a metalloproteinase potentially related to the ADAM family or MMP family of proteases previously implicated in the catabolism of the extracellular matrix.  (+info)

The cellular ecology of progressive neoplastic transformation: a clonal analysis. (4/8613)

A comparison was made of the competence for neoplastic transformation in three different sublines of NIH 3T3 cells and multiple clonal derivatives of each. Over 90% of the neoplastic foci produced by an uncloned transformed (t-SA') subline on a confluent background of nontransformed cells were of the dense, multilayered type, but about half of the t-SA' clones produced only light foci in assays without background. This asymmetry apparently arose from the failure of the light focus formers to register on a background of nontransformed cells. Comparison was made of the capacity for confluence-mediated transformation between uncloned parental cultures and their clonal derivatives by using two nontransformed sublines, one of which was highly sensitive and the other relatively refractory to confluence-mediated transformation. Transformation was more frequent in the clones than in the uncloned parental cultures for both sublines. This was dramatically so in the refractory subline, where the uncloned culture showed no overt sign of transformation in serially repeated assays but increasing numbers of its clones exhibited progressive transformation. The reason for the greater susceptibility of the pure clones is apparently the suppression of transformation among the diverse membership that makes up the uncloned parental culture. Progressive selection toward increasing degrees of transformation in confluent cultures plays a major role in the development of dense focus formers, but direct induction by the constraint of confluence may contribute by heritably damaging cells. In view of our finding of increased susceptibility to transformation in clonal versus uncloned populations, expansion of some clones at the expense of others during the aging process would contribute to the marked increase of cancer with age.  (+info)

Micronucleus test using cultured new born rat astrocytes. (5/8613)

Micronuclei is induced in cytoplasm as a consequence of the formation of chromosomal fragments or remaining chromosomes during cell division by the cause of clastogens or spindle poisons, and is used as an indicator of genotoxicity screening tests. There are few short-term genotoxicity screening tests using brain cells. We attempted to establish a new in vitro micronucleus test (MN test) system by use of central nervous system cells. Primary cultured astrocytes were prepared from newborn male Sprague-Dawley (SD) rats. In growth curve of astrocytes, doubling time was determined to be 31 h. In time study, the highest frequency of micronuclei was observed at 48 h, 72 h and 6 h-exposure-66 h-recovery by vincristine (VCR), mitomycin C (MMC) without metabolic activation system and cyclophosphamide (CPM) with metabolic activation system, respectively. Dose-response relationships between micronucleus frequency and concentrations of MMC, VCR and CPM were observed, respectively. It is suggested that the in vitro MN test using new born rat-astrocytes could be used as a screening test of environmental and occupational genotoxic chemicals in the central nervous system cells.  (+info)

In-vitro fertilization and culture of mouse embryos in vitro significantly retards the onset of insulin-like growth factor-II expression from the zygotic genome. (6/8613)

In this study, the effect of in-vitro fertilization (IVF) and culture of mouse embryos in vitro on the normal expression of insulin-like growth factor-II (IFG-II) ligand and receptor was examined. The expression of IGF-II increased in a linear fashion at least up to the 8-cell stage of development. IGF-II expression in embryos collected fresh from the reproductive tract was significantly (P < 0.001) greater than in embryos fertilized in the reproductive tract and cultured in vitro (in-situ fertilized: ISF), and its expression was further reduced (P < 0.001) in IVF embryos at all development stages tested. The expression of IGF-II was significantly (P < 0.001) lower when embryos were cultured individually in 100 microl drops compared with culture in groups of 10 in 10 microl drops of medium. The addition of platelet activating factor to culture medium partially overcame this density-dependent decline of expression. Culture of ISF and IVF zygotes also caused the onset of new IGF-II mRNA transcription from the zygotic genome to be significantly (P < 0.001) retarded, until at least the 8-cell stage of development. This effect was greater (P < 0.05) for IVF than for ISF embryos. Neither IVF nor culture had any obvious effect on IFG-II/mannose-6-phosphate receptor (IGF-IIr) mRNA expression.  (+info)

Isolation and characterization of a new human breast cancer cell line, KPL-4, expressing the Erb B family receptors and interleukin-6. (7/8613)

A new human breast cancer cell line, KPL-4, was recently isolated from the malignant pleural effusion of a breast cancer patient with an inflammatory skin metastasis. This cell line can be cultured under serum-free conditions and is tumorigenic in female athymic nude mice. Flow cytometric analysis revealed the expression of Erb B-1, -2 and -3. Dot blot hybridization showed a 15-fold amplification of the erb B-2. Reverse transcription-polymerase chain reaction analysis showed a detectable level of mRNA expression of all the Erb B family receptors. In addition, all the receptors were autophosphorylated under a serum-supplemented condition. Unexpectedly, transplanted KPL-4 tumours induced cachexia of recipient mice. A high concentration of interleukin-6 (IL-6) was detected in both the culture medium and the serum of mice. The weight of tumours significantly correlated with the serum IL-6 level. The antiproliferative effect of a humanized anti-Erb B-2 monoclonal antibody, rhuMAbHER2, was investigated. This antibody significantly inhibited the growth of KPL-4 cells in vitro but modestly in vivo. Loss of mouse body weight was partly reversed by rhuMAbHER2. These findings suggest that KPL-4 cells may be useful in the development of new strategies against breast cancer overexpressing the Erb B family receptors and against IL-6-induced cachexia.  (+info)

Generation and characterization of human smooth muscle cell lines derived from atherosclerotic plaque. (8/8613)

The study of atherogenesis in humans has been restricted by the limited availability and brief in vitro life span of plaque smooth muscle cells (SMCs). We describe plaque SMC lines with extended life spans generated by the expression of the human papillomavirus (HPV)-16 E6 and E7 genes, which has been shown to extend the life span of normal adult human aortic SMCs. Resulting cell lines (pdSMC1A and 2) demonstrated at least 10-fold increases in life span; pdSMC1A became immortal. The SMC identity of both pdSMC lines was confirmed by SM22 mRNA expression. pdSMC2 were generally diploid but with various structural and numerical alterations; pdSMC1A demonstrated several chromosomal abnormalities, most commonly -Y, +7, -13, anomalies previously reported in both primary pdSMCs and atherosclerotic tissue. Confluent pdSMC2 appeared grossly similar to HPV-16 E6/E7-expressing normal adult aortic SMCs (AASMCs), exhibiting typical SMC morphology/growth patterns; pdSMC1A displayed irregular cell shape/organization with numerous mitotic figures. Dedifferentiation to a synthetic/proliferative phenotype has been hypothesized as a critical step in atherogenesis, because rat neonatal SMCs and adult intimal SMCs exhibit similar gene expression patterns. To confirm that our pdSMC lines likewise express this apparent plaque phenotype, osteopontin, platelet-derived growth factor B, and elastin mRNA levels were determined in pdSMC1A, pdSMC2, and AASMCs. However, no significant increases in osteopontin or platelet-derived growth factor B expression levels were observed in either pdSMC compared with AASMCs. pdSMC2 alone expressed high levels of elastin mRNA. Lower levels of SM22 mRNA in pdSMC1A suggested greater dedifferentiation and/or additional population doublings in pdSMC1A relative to pdSMC2. Both pdSMC lines (particularly 1A) demonstrated high message levels for matrix Gla protein, previously reported to be highly expressed by human neointimal SMCs in vitro. These results describe 2 novel plaque cell lines exhibiting various features of plaque SMC biology; pdSMC2 may represent an earlier plaque SMC phenotype, whereas pdSMC1A may be representative of cells comprising an advanced atherosclerotic lesion.  (+info)

If you have a question about this talk, please contact Ilana Spilka.. Increasing evidence suggests that the tumor heterogeneity is rooted in the existence of a very small sub-population of stem-like cells (CSCs) within the population of tumor cells. Since cancer takes many years to grow, it is important to develop in vitro models to study tumor initiation and progression. In an effort to regulate the cancer cell microenvironment, my laboratory has merged material synthesis, microscale technologies, and cancer biology to develop an engineered 3D matrix to delineate the role of individual factors in the tumor microenvironment on CSC maintenance, self-renewal, and differentiation. I will demonstrate in my talk that engineered matrices can enrich the CSC subpopulation of cancer cells which is potentially useful in cancer drug screening and personalized cancer treatment..

ABSTRACT. Vascular formation in vivo involves several processes and signal cascades subsequently occurring in the embryo. Several models by ES cells have been reported for analysis in vitro. We show here a 3D culture system using collagen gel (AteloCell) as a simple and useful system for investigating vascular formations and analyzing the roles of factors in vivo. Although VEGF and PDGF are growth factors with multi-potentials for vascular formation, their sequential roles have not been elucidated. We investigated the effects of VEGF and PDGF B signals for vascular formation by a 3D culture system that embedded embryoid bodies (EBs) from ES cells into a collagen gel. After embedding EBs in the collagen gel with a medium containing VEGF, EBs gave off CD105 immunopositive vessels as the initial step of vasculogenesis. When the factor in the culture medium for EBs was switched from VEGF to PDGF B after 5 days of culture, the morphological features of vessels varied, suggesting the occurrence of ...

Infiltration of colorectal carcinomas (CRC) with T-cells has been associated with good prognosis. There are some indications that chemokines could be involved in T-cell infiltration of tumors. Selective modulation of chemokine activity at the tumor site could attract immune cells resulting in tumor growth inhibition. In mouse tumor model systems, gene therapy with chemokines or administration of antibody (Ab)-chemokine fusion proteins have provided potent immune mediated tumor rejection which was mediated by infiltrating T cells at the tumor site. To develop such immunotherapeutic strategies for cancer patients, one must identify chemokines and their receptors involved in T-cell migration toward tumor cells. To identify chemokine and chemokine receptors involved in T-cell migration toward CRC cells, we have used our previously published three-dimensional organotypic CRC culture system. Organotypic culture was initiated with a layer of fetal fibroblast cells mixed with collagen matrix in a 24 well tissue

The epithelial-mesenchymal transition allows cancer cells to remodel the extracellular matrix and invade tissues. However, invasive squamous cell carcinoma (SCC) cells do not lose their epithelial markers, which led Gaggioli et al. to investigate how these cells invaded tissues. The authors devised a three-dimensional culture system consisting of a matrix block, containing mainly collagen and laminin, placed in culture medium with its upper surface exposed. SCC cells placed on this surface did not invade the matrix when cultured alone but did so when cultured with fibroblasts from tumors, as determined by immunohistochemical staining. Invasion by SCC cells was blocked when a thin sheet of matrix was placed between the fibroblasts and the SCC cells. Differential fluorescent labeling of SCC cells and fibroblasts showed that a chain of invading SCC cells in the matrix was always preceded by a fibroblast. Electron and reflectance microscopy revealed that tracks in the matrix generated by ...

The majority of in vivo models of metastasis determine the effect of experimental conditions (usually via knock-out mice) by relying on the end point of secondary tumor formation at a distal site (14). However, the steps occurring between tumor cell injection and metastatic tumor formation are effectively shrouded in these models (15). Despite advances in imaging to monitor these processes, a crucial step of metastasis-the invasion and colonization of cancer cells upon extravasation-remains an elusive target. This study describes a three-dimensional culture system developed to model this phase in vitro and establishes the efficacy of this novel system by demonstrating that cells from disparate phases of melanoma invade the matrix in a manner proportional to their known metastatic capabilities. Specifically, the highly metastatic C8161.9 stayed true to its documented in vivo behavior (21), ferociously staking claim to much of the surrounding matrix (Fig. 1A-C). The sporadically metastatic M14 ...

We characterized fully and adapted a method15 to isolate ECs from mouse aortas that allowed us to profile gene expression in ECs during the early stages of atherosclerosis. This method provides a quick and efficient way to collect MAEC RNA, generally yielding RNA from a mouse in ,1 hour after harvesting, and has several advantages instead of cell culture methods. Not only do we avoid the passage and dedifferentiation issues that occur during cell culture procedures but we are able to directly assay the transcriptional state of the cells that closely represents their in vivo status. In these experiments, we were able to obtain the transcriptional state of ECs in prelesion aortas, and through the use of 1 RNA amplification, we were able to perform microarray analysis on MAECs taken from a single mouse. Moreover, we demonstrate that the whole aorta, with its endothelium intact, can be treated in cell culture medium similar to conventional cell culture with the added advantage of not disrupting the ...

Mammalian cell culture has long been an invaluable tool in cell biology, drug discovery, and regenerative medicine. When cell culture techniques were first developed, 3-Dimensional (3D) systems were utilized. That rapidly changed due to cost and efficiency concerns resulting in cell culture being performed today with adherent cells grown on flat and rigid two-dimensional (2D) substrates, including polystyrene or glass. Advances in our understanding of cell physiology and failures in clinical trials have provided the impetus to move away from 2D systems and back to a more in-vivo-like 3D environment. The advance of these new technologies and screening methodologies have allowed scientists to assess more realistic functional capabilities of cells. The following course will focus on the cellular microenvironment and its importance when developing and screening cell-based assays using primary, stem cell, and immortalized cultures in 3D systems.. ...

Bioinspired, Non-Covalent Assembly of Materials: Stem cell activities, including self-renewal and differentiation, are strongly influenced by signals present in their microenvironment. Our group is using novel materials chemistry to control the signals present in the local stem cell microenvironment. Our approaches use non-covalent interactions between biological molecules (e.g. proteins, DNA strands) to assemble signaling complexes on cell culture substrates and within extracellular matrices. These non-covalent assembly approaches are being used to understand/control stem cell differentiation and as a mechanism for targeted drug delivery.. Bio-responsive Materials: Biological macromolecules, including proteins and poly(nucleotides), provide the most basic unit of function in living systems. For example, proteins fold to give structurally well-defined three-dimensional macromolecules and in many cases undergo highly complex changes in response to a broad spectrum of environmental cues, including ...

  • Research into developing advanced tumor cell culture models in a three-dimensional (3D) architecture that more prescisely characterizes the disease state have been undertaken by a number of laboratories around the world. (
  • These 3D cell culture models are particularly beneficial for investigating mechanistic processes and drug resistance in tumor cells. (

  • A team of researchers at the Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine has developed a technique for growing ovarian cancer cell lines that mimic the original tumor in long-term cultures. (
  • The technique offers hope for quickly advancing precision medicine applications for a variety of cancers by enabling clinicians to test therapies on cells from a patient's own tumor in the laboratory, thus identifying the most targeted therapy for that patient. (
  • The key to Ince's research is his development of a mixture of essential nutrients in liquid form, commonly referred to as a "cell culture medium," that permits cells taken from a patient tumor to replicate in a Petri dish and become a permanent cell line faithful to the characteristics of the original tumor over a long period of time in the laboratory. (
  • Using the novel medium, his laboratory has developed 25 unique lines using ovarian cancer tumor cells from 26 patients. (
  • Only a rare minority of cancers are able to grow as cell lines in these media, and when they do, they are often very different at the molecular level from the tumor of origin. (
  • Importantly, the 25 new ovarian tumor cell lines retain the genomic landscape, histopathology and molecular features of the original tumors. (
  • Thus tumor cell lines derived using this new methodology represent a significantly improved new platform to study human tumor pathophysiology and response to therapy. (
