Isolation and long-term culture of diploid mammalian cell lines.
Cells have been established in continuous culture from human and animal tissues, both normal and carcinomatous. From 197 specimens, 105 could be maintained in vitro for varying lengths of time, 27 for more than 6 months. In all cases the cells were found to be diploid. Cell lines with both epithelial and fibroblastic morphology have been isolated in medium 199 with added fetal calf serum, but a...
متن کاملCell isolation and culture.
Cell isolation and culture are essential tools for the study of cell function. Isolated cells grown under controlled conditions can be manipulated and imaged at a level of resolution that is not possible in whole animals or even tissue explants. Recent advances have allowed for large-scale isolation and culture of primary C. elegans cells from both embryos and all four larval stages. Isolated c...
متن کاملIsolation and detection of Mycoplasma pneumoniae from cell culture by culture and PCR.
Background: Mycoplasma pneumoniae is one of the major species of mycoplasmas which could contaminate cell cultures. Identification of M. pneuminae is significant because Mycoplasmas could contaminate and have unsuitable effect on the cell cultures. Rapid detection of these contaminations is so important and it could be significant role in preventing and controlling of contamination in cell cul...
