Fine structure of the capillaries in the spinal cord of human embryos at 7th week.
Study were made in three human embryos at developmental stages 18 and 19 (7th week). It was shown that the wall of the capillaries is formed by one or two endothelial cells, which are separated by perivascular space from the glial cells. Endothelial cells possessed cilia projecting into the vascular lumen and are connected through the zonulae occludentes.
