pericyte

 [per´ĭ-sīt]
one of the peculiar elongated, contractile cells found wrapped about precapillary arterioles outside the basement membrane.

(per'i-sīt), Do not confuse this word with parasite.
One of the slender, mesenchymallike cells found in close association with the outside wall of postcapillary venules; it is relatively undifferentiated and may become a fibroblast, endothelial cell, or smooth muscle cell.
