Figure 3

A high-power-field microscopic evaluation of cartilage histology with special staining. (a) Repaired cartilage from the autologous chondrocyte transplantation group (hematoxylin and eosin) demonstrates a cellular arrangement, (b) and glycosaminoglycan-containing extracellular matrix, which has been shown by positive staining of Safranin O. (c) Repaired fibrocartilage from the subchondral drilling group with fibroblast-like cells, (d) and without glycosaminoglycan matrix was found using Safranin O stain.
