| Research Abstract |
The results were as follows ; (1) Immunohistochemical localization of epidermal growth factor (EGF) were observed in decidualized human endometrium. (2) Production of EGF by decidual cells was clearly demonstrated immunoprecipitation-autoradiography. (3) Scatchard plots revealed decidual cell possesses single kind of EGF receptor with Kd of 1.02 nM and Bmax of 89.4 pM/2x10^5 cells. (4) EGF dosedependently inhibited prolactin production by decidual cells with IC_<50> of 700 pg/ml. (5) The inhibitory effect of EGF on prolactin production was induced by the tyrosine kinase and protein kinase C. (6) EGF enhanced specific protein phoshorylation (48kDa, acidic protein) by the activation of protein kinase C.
