Epiphyseal growth cartilage. a Blood vessels in the medial femoral condyle of an 11-week old pig. The sample has been cleared in 100% methylsalicylate, and the blood vessels were perfused with barium sulfate to enhance contrast. An arterial blood vessel penetrating the epiphyseal growth cartilage from the perichondrial plexus is called a vascular trunk. In the image, a vascular trunk is running parallel to the ossification front with perpendicular-oriented branches. The arrow points to a necrotic cartilage canal that was observed during histological examination. Included with permission from [17]. b 5 mm thick slab from the distal femur of a 20 kg pig. A cross-section of the secondary ossification center (SOC) and the epiphyseal growth cartilage (EC) can be observed. The approximate transition to the immature articular cartilage (AC) is indicated by a dashed line on the medial femoral condyle
