Viability and cell cycle analysis of equine fibroblasts cultured in vitro
(Springer, 2010-08-01)
This experiment aimed to study equine fibroblasts in culture analyzing and the cell cycle and viability of cells pre- and post-freezing. Skin fragments were obtained from 6 horses and cultured in DMEM high glucose + 10% ...
Chromosome damage induced by 5-azacytidine under the influence of caffeine or cytosine arabinoside in CHO-K1 (wild-type) and XRS-5 (mutant) cell lines
(2001-07-14)
5-azacytidine (5-azaC) treatment combined with cytosine arabinoside (ara-C) or caffeine were performed in vitro in Chinese hamster cells, CHO-K1 (wild-type) and xrs-5 (mutant) cell lines, in order to compare the cell ...
Kinetics of spermatogenesis in the Mongolian gerbil (Meriones unguiculatus)
(2002-05-06)
The Mongolian gerbil (Meriones unguiculatus) is a small rodent native to the arid regions of Mongolia and Northeastern China. The present study provides descriptions of both the cellular associations of the seminiferous-epithelium ...
DETECTION OF CELL-PROLIFERATION IN TISSUE-SECTIONS
(Associação Brasileira de Divulgação Científica (ABRADIC), 1993-07-01)
1. Cell proliferation is of interest since abnormal cell proliferation appears to be a precursor of tumorigenesis and also because the quantitative description of cell proliferation in tumors can be used to predict the ...
Morpho-histochemical characterization of salivary gland cells of males of the tick Rhipicephalus sanguineus (Acari: Ixodidae) at different feeding stages: description of new cell types
(Springer, 2010-01-01)
This study describes the changes undergone by cells of the salivary glands of unfed and feeding (at day two and four post-attachment) Rhipicephalus sanguineus males, as well as new cell types. In unfed males, types I and ...
Heparan sulfate and cell division
(Associação Brasileira de Divulgação Científica, 1999-05-01)
Heparan sulfate is a component of vertebrate and invertebrate tissues which appears during the cytodifferentiation stage of embryonic development. Its structure varies according to the tissue and species of origin and is ...
Morphological events during the Trypanosoma cruzi cell cycle
(Elsevier B.V., 2007-04-01)
The replication and segregation of organelles producing two identical daughter cells must be precisely controlled during the cell cycle progression of eukaryotes. in kinetoplastid flagellated protozoa, this includes the ...
HEPARAN-SULFATE PROTEOGLYCAN AND CONTROL OF CELL-PROLIFERATION - ENHANCED SYNTHESIS INDUCED BY PHORBOL ESTER (PMA) DURING G(1)-PHASE
(Assoc Bras Divulg Cientifica, 1994-09-01)
The effect of phorbol 12-myristate-13-acetate (PMA), a tumor-promoting phorbol ester, on the synthesis of proteoglycans of endothelial cells in culture was investigated. This phorbol activates protein kinase C (PKC) when ...
Biocompatibility of denture base acrylic resins evaluated M culture of L929 cells. Effect of polymerisation cycle and postpoymerisation treatments
(Blackwell Publishing, 2007-03-01)
Objective: the purpose of this study was to evaluate the effect of two post-polymerisation treatments and different cycles of polymerisation on the cytotoxicity of two denture base resins.Materials and methods: the resins ...
