Loss of PGI₂ antiapoptotic effect when added after PAPA/NO

Treatments	Apoptosis (%)
None	16±3
PAPA/NO	42±4*
PGI2 1 min+PAPA/NO	23±3#
PAPA/NO 15 min+PGI2	42±5¶

Megakaryocytes were treated as indicated, and 18 h later, the percentage of apoptosis was determined by flow cytometry (n=3).

^*P<0.05 vs none.

^#P<0.05 vs PAPA/NO alone.

^¶P<0.05 vs PGI₂ 1 min+PAPA/NO alone.
