Abstract/OtherAbstract:
|
The viability and the recovery (cell attachment to the dish) after thawing of human diploid fibroblasts (TIG-1) frozen by four different methods were studied at different passages. Improved results were observed in a medium of 30% fetal bovine serum plus 15% glycerol, compared with the conventional medium which contained 10% fetal bovine serum plus 10% glycerol. Centrifugation to remove glycerol immediately after thawing had a negative effect on the viability and recovery of cells. The recovery of cells after freezing and thawing showed a maximal value in the middle of phase II (PD 35) during the finite lifespan of the cell (average PD 67). This results indicates that the cells at early and late passages are sensitive to injury by freezing and thawing. The modified method yielded improved recovery, especially in the cells at early and late passages, except for the extremely senile stage. The recovery was also affected by the state of cell growth after inoculation. |
