Temperature affected PGE2 production in the cultured
ampullary epithelial cells. PGE2 concentration was
significantly higher at 40.5 8C than at 38.5 8C (Fig. 3A).On the other hand, elevated temperatures did not affect
PGE2 production in the isthmic epithelial cells (Fig. 3B).
The culture temperature had no effect on PGF2a
production in either the ampullary cells or isthmic
cells (Fig. 3C and D). In the experiments described
below, the cells were incubated at 38.5 and 40.5 8C,
because PGE2 production at these temperatures is
significantly different.
