the time course of uptake followed by spontaneous release of mitochondrial ca2+ from tubule cells deliberately permeabilized with digitonin , then incubated for prolonged periods , indicated that the decreases of tubule cell ca2+ during reoxygenation of hypoxic suspensions and prolonged incubation of atp-treated tubules were likely to be attributable to loss of ca2+ from free mitochondria and those in damaged cells rather than to extrusion by intact cells .
