OBJECTIVES: Soluble fms-like tyrosine kinase-1 (sFlt-1) and soluble endoglin (sEng) are the most studied molecules in preeclampsia. However, most trophoblast cell lines do not secrete both these factors. Thus, we set out to characterize protocols to functionally investigate sFlt-1 and sEng from primary trophoblast. STUDY DESIGN: Primary trophoblasts were isolated from term placenta by percoll gradient, then negative selection using a CD9 antibody. Purity was assessed by cytokeratin 7 immunostaining. We first examined the effects of CD9 negative selection on sFlt-1, sEng and hCG secretion and the ability of forskolin to enhance syncytialization. We then examined the effects of hypoxia on sFlt..View full abstract
