Growth cartilages were obtained from humeri, femora, and ulnae of 31 pigs between 1 and 169 days old. On the basis of stain uptake and distribution, distinct layers were identified in articular-epiphyseal cartilage complexes and growth plates. The laminated appearance was dependent on stain uptake by territorial and interterritorial matrices and was more distinct in pigs greater than 15 days old. There was morphologic heterogeneity, which probably represented a functional heterogeneity, among chondrocytes in all layers and zones of both types of growth cartilage. The laminar appearance of growth cartilages and the distribution of different types of cells were similar for all pigs in each age category and for all sites.
从1至169日龄的31头猪的肱骨、股骨和尺骨获取生长软骨。根据染色剂摄取和分布情况，在关节-骨骺软骨复合体和生长板中识别出不同的层。分层外观取决于局部和非局部基质对染色剂的摄取，且在15日龄以上的猪中更明显。在两种类型的生长软骨的所有层和区域的软骨细胞之间存在形态学异质性，这可能代表功能异质性。每个年龄组的所有猪以及所有部位的生长软骨的层状外观和不同类型细胞的分布都是相似的。
