Endothelial cells induce β-catenin activity in adrenal cortical cells. Wnt-signaling, cAMP, Akt or PKC pathways are not involved. MEK, PI3-kinase and receptor tyrosine kinases are involved. Stimulation of β-catenin and StAR activity is partly mimicked by bFGF. bFGF is produced and secreted by human umbilical cord endothelial cells.
