[Immunohistochemical localization of alpha-fetoprotein in the vitelline sac of a two-week old human embryo].
Histological sections of a stage 6b human embryo (13-15 days old) were immunohistochemically stained for specific alphafoetoprotein (AFP). Conspicuous AFP+ endodermal cells were observed in the yolk-sac wall using the ABC peroxidase technique, which gave consistent results on dismounted and decolorized old slides.
