AbstractThe cells of an established mouse fibroblast line, 3T3, have a high
plating efficiency and grow rapidly in sparse culture, but stop growing at a
very low saturation density in comparison with other lines, because 3T3 is
extremely sensitive to contact inhibition of cell division. After each medium
change, however, there occurs in a small fraction of the cells in a saturation
density culture... hiện toàn bộ
