title: Influence of extracellular matrix on the proliferation of human amniotic fluid cells in vitro.
abstract: Factors which influence the proliferation of human amniotic fluid cells in vitro have potential importance in reducing the time for prenatal diagnosis. Fibroblast growth factor (FGF) has been shown to be mitogenic for human amniotic fluid cells. The observation that cells which respond to FGF in vitro produce their own extracellular matrix (ECM), led to the use of an ECM as a substrate to assess proliferation. Pooled amniotic fluid cells maintained on an ECM prepared from bovine corneal endothelial cells demonstrated a significant increase in proliferation when compared with cells maintained on plastic substrate in the presence or absence of FGF. If FGF was added to cultures of amniotic fluid cells maintained on ECM, further increases in proliferation were noted compared with cells maintained on ECM in the absence of FGF. These results indicate that the substrate upon which amniotic fluid cells are maintained can have a profound influence on their proliferation.
