Two- and three-dimensional ultrastructure of endothelium and pericyte interdigitations in capillary of human granulation tissue.

Two- and three-dimensional electron microscopic observation in the immature capillary of the human granulation tissue revealed cytoplasmic interdigitations (CID) between the endothelium and the pericyte. These were composed of a cytoplasmic projection and indentation, and there was a gap space without basement membrane-like components between the two cell… CONTINUE READING
