Photomicrographs of normal femoral head of immature piglet. (A) Polycut section view (H&E, ×4). (B) Higher magnification of the growth cartilage surrounding the secondary ossification center shows normal columnar pattern (H&E, ×10). (C) Higher magnification of the growth plate cartilage of the metaphyseal physis shows normal cellular zones including reserve, proliferative and hypertrophic zones. Vascular invasion of terminal hypertrophic chondrocytes and primary spongiosa formation in the metaphysis, indicative of enchondral ossification, are evident (H&E, ×10).
