Figure 1. Relationship between the donor ages, time from death to culture and time to initial growth in cultivated corneal epithelial stem cells. A: Correlation graph between the donor ages versus time to initial growth. Cultured cells from younger donors significantly grew faster than cells from older donors (p=0.0069). B: Correlation graph between the time from death to culture versus time to initial growth. The shorter the time from death to culture, the faster initial cell growth was observed, although not significantly (p=0.0749).
