pericyte

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

per·i·cyte

(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.

The "trophic" effects of MSCs establish a regenerative microenvironment at the site of injury by (a) inhibiting ischemia-related apoptosis, (b) by inhibiting scar formation, (c) by stimulating angiogenesis by secreting large amounts of vascular endothelial growth factor (VEGF) and by transforming some of the MSCs back into pericytes that function to stabilize the fragile, newly forming capillaries, and (d) by secreting tissue progenitor-specific mitogens so that the slow process of tissue regeneration is enhanced [29].
