The authors examined some age and topographic peculiarities in the occurrence and microscopic characteristics of glucosamineglycanes, glycogen, lipids, calcium compounds and collagenous fibres during the course of the embryonal development of man. The deposition of glycogen and lipids in chondroblasts after the third-fourth week of embryonal development was indicated as well as the appearance of glucosamineglycanes in the intercellular substance during the same period. The role of the same substances in the differentiation of the cartilaginous tissue was stressed. The authors pointed out the well manifested PAS-reactivity of the superficial layer of the periosteum as a typical peculiarity of this formation.
作者研究了人类胚胎发育过程中氨基聚糖、糖原、脂质、钙化合物和胶原纤维在发生及微观特征方面的一些年龄和部位特点。指出胚胎发育第三至四周后糖原和脂质在成软骨细胞中的沉积，以及同期细胞间基质中氨基聚糖的出现。强调了这些物质在软骨组织分化中的作用。作者指出骨膜表层明显的PAS反应性是该结构的典型特征。
