Fig 7. Result of implanting 8-braid SIS scaffold soaked in 0.8 aPBS.

Left, 8-braid scaffold prior to hydration. Middle and right, 50% defect at one and two months, respectively, after embedding SIS scaffold alone. No cartilage has regenerated. In the one-month specimen, the implanted scaffold is still visible within the gap (arrow). At two months, the scaffold is largely degraded, and connective tissue and muscle has regenerated into the gap (arrow). M = muscle. Scale bar = 400 μm.
