Platelet-rich plasma increases transforming growth factor-beta1 expression at graft-host interface following autologous osteochondral transplantation in a rabbit model

Figure 5 Sagittal section of the same osteochondral graft (20 ×). The graft was treated with saline and the knee was harvested 12 wk following surgery. The interface between host and graft tissue is integrated at points but considerable gapping remains.
