Suspension cell culture is commonly used to culture nonadhesive cell lines like hematopoietic cells, plant cells, and insect cells. [1] While some cell lines are cultured in suspension, the majority of commercially available mammalian cell lines are adherent.
Many methods are used to identify cell lines, including isoenzyme analysis, human lymphocyte antigen (HLA) typing, chromosomal analysis, karyotyping, morphology and STR analysis. [35] One significant cell-line cross contaminant is the immortal HeLa cell line. HeLa contamination was first noted in the early 1960s in non-human culture in the USA.
Cell samples can be taken from tissue explants or cell suspension cultures. Adherent cell cultures with an excess of nutrient-containing growth medium will continue to grow until they cover the available surface area. [3] Proteases like trypsin are most commonly used to break the adhesion from the cells to the flask. Alternatively, cell ...
Microcarrier cell culture, however, was the breakthrough required for cell culture to reach industrial and clinical significance. [2] Studies have shown that microcarrier suspensions, compared to multi-layer vessel culture, improve cell yield by 80-fold at only ten percent of Good Manufacturing Practice space, and only sixty percent of the ...
This cultivar of tobacco is kept as a cell culture and more specifically as cell suspension culture (a specialized population of cells growing in liquid medium, they are raised by scientists in order to study a specific biological property of a plant cell). In cell suspension cultures, each of the cells is floating independently or at most only ...
K562 cells were the first human immortalised myelogenous leukemia cell line to be established. K562 cells are of the erythroleukemia type, and the cell line is derived from a 53-year-old female chronic myelogenous leukemia patient in blast crisis. [1] [2] The cells are non-adherent and rounded, are positive for the bcr:abl fusion gene, and bear ...
Tissue culture flasks. RPMI 1640, simply known as RPMI medium, is a cell culture medium commonly used to culture mammalian cells. [1] RPMI 1640 was developed by George E. Moore, Robert E. Gerner, and H. Addison Franklin in 1966 at Roswell Park Comprehensive Cancer Center (formerly known as Roswell Park Memorial Institute), from where it derives its name. [2]
Alternatively, to avoid dissociation into single cells, EBs can be formed from hESCs by manual separation of adherent colonies (or regions of colonies) and subsequently cultured in suspension. Formation of EBs in suspension is amenable to the formation of large quantities of EBs, but provides little control over the size of the resulting ...
