  1. Numbers in bold accompanied by an * indicate statistically significant correlation coefficients (P <0.05). BVD, blood vessel diameter; CAC, circulating angiogenic cells seeded on a collagen scaffold; CAC (OPN), circulating angiogenic cells exposed to osteopontin and seeded on a collagen scaffold; I, inflammatory cell infiltrate; Ld, length density of blood vessels; Rd, radial diffusion distance; Sd, surface density of blood vessels; WC, percentage wound closure.
