Scanning electron microscopy analysis of vascular corrosion casts of the specimens two weeks after implantation. In all specimens the neocapillary network displayed characteristics of an immature vascular bed, such as absence of a distinct vascular hierarchy and vivid angiogenesis in terms of sprout formation. In comparison to group A (A) the density of the neocapillaries was higher in the treatment group B (B). (magnification x 500).
