3. Fig. 2
Photomicrographs of histomorphological changes of joint cartilage stained by H&E. Normal appearance of joint cartilage (A). Invasion of fibroblastoid infiltrate in the cartilage (B) and the cartilage and subchondral bone (C). Chondrocytes forming strings with elongated collagen fibers in parallel bands giving it the appearance of fibrocartilage (D). Scale A–C=100mm, D=50mm.
