Identification of third generation of chondrocytes (×200). (a) Chondrocytes were stained using toluidine blue. Immunohistochemical staining of type II collagen demonstrated that (b) the cytoplasm of the negative group of chondrocytes was unstained, whereas (c) the cytoplasm of chondrocytes was stained.
