To investigate the role of retinoids on human placental development and functions, we characterized the spatial distribution of retinoid receptors in human term chorionic villi. In situ hybridization with 35S labeled sense and antisense probes for the RARs, alpha, beta, gamma and RXRs, alpha, beta, gamma, specifically detected only RAR alpha and RXR alpha. Both RAR alpha and RXR alpha mRNA were preferentially expressed in the trophoblast cell layer. This syncytiotrophoblast expression was confirmed by immunohistochemical analyses using anti-RAR alpha and RXR alpha antibodies. Using trophoblast cells in culture, we then studied the effect on hCG secretion of 0.1 microM RA physiological forms and of selective RAR alpha and RXR alpha synthetic agonists. Only RXR alpha specific ligands such as physiological 9-cis RA and synthetic Ro 25-7386 stimulated hCG secretion (doubled). These results suggest an important role for RXR alpha in human placental development and function.
