Cotton-like microfibers composed of: (a) 45S5, (b) 13-93B3, and (c) Cu-doped 13-93B3 BGs. (d) Image of 13-93B3 BG microfibers at a high magnification (the arrows mark glass beads). (e) Camera image of the Cu-doped 13-93B3 BG microfiber implant. The periodic acid Schiff (PAS)-stained sections of soft tissue exposed (for 4 weeks) to implanted BG microfibers composed of: (f) none (sham control); (g) 45S5, (h) 13-93B3, and (i) Cu-doped 13-93B3 (the arrows mark the microvessels found in the tissues).
