Metabolism of prostaglandin E2 by mouse embryo palate mesenchyme cells in vitro

Mouse embryo palate mesenchyme cells synthesize a number of prostaglandins, particularly prostaglandin E2 (PGE2). However, the ability of such cells to metabolize prostaglandins was unknown. By use of radiolabeled PGE2 we determined that palate mesenchyme cells have little ability to degrade that prostaglandin in vitro but are able to metabolize products formed from its spontaneous degradation.
