Assessment of the effect of caspase inhibition on postfreeze viability in VD3-treated and/or frozen PC-3 samples. Metabolic activity of untreated or VD3 dose-escalated PC-3 cells was obtained in response to caspase inhibition and freezing to −15°C and −20°C. A, Normothermic controls; B, −15°C; C, −20°C.
