[Macrophages in the choroid plexus of the embryonic telencephalon].
Using electron microscopy and immunocytochemistry distribution of macrophages in anlage of telencephalon choroid plexus was studied in 5-9 wks old human embryos. CD68 gene expression by intraepithelial macrophages that appear in anlage of choroid plexus (epithelial plate) was established to begin at 5th week of development. Accumulation of macrophages in embryonic connective tissue of choroid plexus anlage, appearance of intraepithelial macrophages, following appearance of free macrophages and supraependymal cells in brain ventricles (on wk 6-7) indicates that in human embryos choroid plexus anlage is a migration zone for macrophageal serie cells that penetrate into the cavity of the developing brain.
