Abstract
Attempts were made to select for trophoblast cells in cultures of mixed cell populations derived from preterm (7 to 12 wk) or term human placentas. Epidermal growth factor added to cultures on solid or porous supports caused proliferation of epithelial-type cells to give a confluent monolayer but did not increase the expression of differentiated function. The presence or absence of placental basement membrane collagen as substrate made little apparent difference; however a porous basement membrane collagen support led to increased differentiated function. Initial production of human chorionic gonadotrophin was increased and after 4 wk in culture a substantial proportion of the cells exhibited alkaline phosphatase activity. Epidermal growth factor and a substrate of placental basement membrane collagen on a porous support favorably influence the growth and differentiation of human trophoblast cells in culture.
