Abstract

Abstract The survival at 4 °C of mouse fibroblasts (strain L-929) and rat liver cells (strain JTC-25·P5) was kinetically analysed after they had been pre-incubated at 37 °C in medium with or without supplement of serum. Both the composition of medium used for preincubation at 37 °C and that employed for storage at 4 °C had influence on the survival period.When the cells had been grown at 37 °C in Eagle minimal essential medium (MEM) alone, they rapidly lost their viability at 4 °C from the beginning. However, when grown at 37 °C in MEM supplemented with calf serum, they maintained viability at 4 °C for about 16 days and 8 days for L cells and JTC-25·P5 cells respectively, before the initiation of rapid loss of viability. The presence of macromolecular fraction of calf serum in the medium during preincubation was found to be responsible for the prolongation of survival at 4 °C.
