title: Human chorion cells respond to growth factors but lose steroidogenic capacity in primary monolayer cell culture.
abstract: This study has defined a method for preparation and monolayer culture of cells from chorion laeve. Cell number and cell protein content are stable over 7 d in culture. The cells will divide in response to epidermal growth factor in the presence of a supplemented, enriched medium and a collagen matrix, but they lose steroidogenic activity over time in culture. This culture system can be used as the starting point for the development of a chemically defined hormone-supplemented, serum-free culture system for studies of chorion cell differentiation and fetal membrane cell interactions.
