Expression of mRNA encoding Ptgdr and Gpr44 in EPI and RES collected from whole oviducts of mice. Immature mice were treated with 5 IU of PMSG to induce follicular development and killed 48 h later. Data are the means ± sem for real-time PCR analysis of three samples for each cell type, with EPI and RES cells pooled from three to four mice for each sample. Levels of mRNA were obtained by real-time PCR and are expressed as fold changes. For each time point within a panel, an asterisk indicates differences in gene expression (P < 0.05).
