[Specificity of the protein distribution in the nucleus and cytoplasm of the cells of provisional and definitive structures in early human embryos].
The highest amount of total protein in a 17-day human embryo is found in nuclei of the ectodermal germ layer. Histones are distributed as small clods whereas histones-like proteins vary in quantity in the apical and basal parts of the cells. During the 2nd and 3d months of embryogenesis protein topography in cells of different organs and systems is not the same and corresponds to the human histo- and organogenesis rate. Protein amount is especially high in chromosomes of dividing cells.
