1. The protein synthesis in chorioallantoic membrane (CAM), amniotic membrane (AM) and yolk sac (YS) were studied by in vitro culture with 14C L-glutamic and immunoautoradiography. 2. The yolk sac synthesizes transferrin, alpha-fetoprotein (AFP) and serum albumin. These three proteins are also synthesized, but only in slight amounts, by AM. A light(More)
Alpha-fetoprotein (AFP) is a major globulin of the embryonic serum of mammals, birds, and other vertebrates. It is synthesized chiefly by the liver and/or the yolk sac. The aim of this work was to confirm the occurrence of AFP in the chorioallantoic membrane (CAM) from 14-day chick embryo. AFP had previously been detected by immunoelectrophoresis in CAM(More)
Very little is known about the biological role of alpha-fetoprotein (AFP) in normal development. This study was undertaken to look for AFP-positive tissues involved in active morphogenetic and histogenetic events. Using a polyclonal antibody specific for AFP and the immunoperoxidase technique, we have studied the AFP localization during the formation of the(More)
The aim of this work was to investigate the localization of alpha-fetoprotein (AFP) in amniotic membrane (AM). By using the immunoperoxidase technique in several developmental stages, which reflected the changes of structure of the AM germinal layers, AFP was detected earliest in 7-day AM and localized selectively in the ectodermal cell layer. This was the(More)
