FIG. 10.

Images (4×) of wound healing at 7, 14, and 21 days after implantation. Blood vessel formation is apparent in porous and nonporous 70:30 col/PCL scaffolds as early as 7 days (white arrow indicates a representative blood vessel). The epidermis in wounds containing 70:30 col/PCL scaffolds with 160 μm pores forms finger-like projections into the dermis, similar to normal unwounded epidermis. Hair follicle formation can also be seen in wounds containing microporous scaffolds (black arrowhead indicates a representative hair follicle). Color images available online at www.liebertpub.com/tea
