Figure 4. Effect of LPA on the production of prostagandins in the rat uterus during the window of implantation.

Uterine strips from rats pregnant on day 5 of gestation (implantation window) were incubated with LPA 50 µM for 6 h and the production of PGF2α (A) and PGE2 (B) was determined by radioimmunoassay. In B: *** p<0.001 vs C. Results are shown as means ± sem. N = 4–6 for each point. C: control.
