enriched fractions of small and large luteal cells were incubated for 2 h with 1 or 10 microm calcium ionophore , a23187 : unstimulated secretion of progesterone and viability in small cells were not affected but these measures were decreased ( p less than 0.01 ) for unstimulated large cells and were significantly correlated ( p less than 0.05 ) .
