Expression of placental leptin and leptin receptor transcripts in early pregnancy and at term

Abstract

Results suggest an ontogenetic decline in leptin mRNA with advancing gestation. Localization of leptin and leptin receptor transcripts in syncytiotrophoblasts, cells also responsible for the production of hormones vital to pregnancy maintenance, suggest a potential for autocrine or paracrine interactions within this tissue. Finally, transcript expression in cultured cells suggests the suitability of in vitro paradigms for future studies of leptin in pregnancy.
