[Synthesis of alpha-fetoprotein and albumin human embryo hepatocytes]

Population aspects of specific secreted proteins (alpha-fetoprotein and serum albumin) were analyzed in the cultured human embryo hepatocytes (6 to 12 weeks' gestation). A method based on local hemolysis in gel of sheep erythrocytes conjugated with antibodies specific of proteins in question. The great majority of individual hepatocytes synthesized both proteins.
