Figure 2

Photomicrographs of Wistar rats’ tibia, showing the epiphyseal cartilage in the coronal plane. Stained by hematoxylin and eosin. In image (a), areas of the epiphyseal disc: proliferative (ZP), hypertrophic (ZH), and vascular invasion (ZIV). These zones are seen in details in the images in (b), (c) and (d). Image (b) shows the ZP, where the chondrocytes are seen flattened into columns (Ct) in condron (Cd) and cartilage matrix (Mz). In image (c), ZH and in image (d), ZIV, hypertrophic chondrocytes (Ch), and erythrocytes (He).
