Growth studies and doubling time of the CMT-1 cell line. A CMT-1 cells demonstrated moderate anisocytosis and anisokaryosis with the majority of cells having multiple nuclei. B CMT-1 cells (passage 9) showed slight anisocytosis and anisokaryosis with the majority of cells having a single nucleus while CMT-1 (passage 50) became more uniformly round to oval in morphology. C The population doubling time of CMT-1 (passage 50) was calculated to be 26.67 h
