Spongiotrophoblast and glycogen trophoblast expression of PRL/PL family members. A – Double in situ hybridization of Pcdh12 (Blue) and Prl7a2 (Brown) in E14.5 placenta. B – Double in situ hybridization of Prl6a1 (Blue) and Prl7a2 (Brown) in E14.5 placenta. C – Summary of spongiotrophoblast and glycogen trophoblast-specific expression patterns as well as genes expressed in both populations.
