Notes:
A new strain of cells, designated as PD-MEK-I, and derived from the kidneys of a rhesus monkey embryo, has been isolated and utilized as a prototype for mass propagation in suspended cell cultures, using techniques similar to those developed for antiobiotic fermentations. The use of the large-volume units for cultivation of tissue cells has been applied. These units are useful for preparing masses of cells for studies of cellular antigens, virus assays, antitumour cytotoxicity studies, and other biologically active materials, as well as seed for continuing cultures. In addition, other methods of roller bottle cultures, shaker flask cultures, spinner cultures, and disposable 1-litre prescription bottles, have been modified so that over 35 different human and animal cell lines are being maintained in continuous culture. Any one of these procedures may be modified for preparing and handling large numbers of replicate cultures as well as for maintaining stock seed cultures. The characteristics of growth of cells utilizing these methods are similar to those encountered in microbial populations and the principles of antibiotic fermentation have been applied appropriately.
