A schematic representation of endochondral ossification highlights the formation of both primary and secondary ossification centers. In the upper right region, the primary center reveals longitudinally arranged cell columns, while the lower right region showcases the secondary center, characterized by radially oriented cell columns.
Radial expansion of the secondary ossification center is evident in this micrograph, contrasting with the vertically aligned cell columns within the epiphyseal growth plate (EGP). The proliferative zone (pz) and hypertrophic/calcification zone (hz) are clearly discernible within the EGP. Hematoxylin and eosin (HE) staining; scale bar, 1000 μm.
