Abstract

The distribution and possible origins of plasma proteins in the human embryonic and fetal brain at different stages of development have been investigated by a combination of isolation and translation of mRNAs and immunocytochemistry using specific antisera. As many as 23 plasma-like proteins have been identified using immunocytochemical methods at the light microscopical level. The presence of mRNAs for 13 of the immunocytochemically positive plasma proteins was demonstrated by in vitro and in ovo translation followed by crossed immunoelectrophoresis and autoradiography; this indicates in situ synthesis of these proteins (e.g., alpha-fetoprotein, alpha 1-antitrypsin, GC-globulin, alpha 2-mac..
