thus , proteoglycans and anionic materials associated with growing capillaries serve to link proliferating and migrating endothelial cells to the extracellular matrix , help to organize the capillary basal lamina , form an anionic surface along the luminal front of capillaries , and probably help stabilize the structure of the capillary wall after proliferation ceases .
