Selected ultrastructural features of chondrocytes and the extracellular matrix in the developing elastic cartilage of the external ear were studied in rat fetuses and young animals. The cytoplasmic lipid droplets were first observed in the 19-day fetus. They increase in number and size during the first post-natal week. The elastogenesis proceeds in the sequence: oxytalan fibers (17-day fetus), elaunin fibers (1-day rat), elastic fibers (5-day rat). Intermediary stages between the randomly oriented individual microfibrils and bundles of microfibrils (oxytalan fibers) were also observed.
在大鼠胎儿和幼龄动物中，研究了外耳发育中弹性软骨的软骨细胞和细胞外基质的选定超微结构特征。在19天的胎儿中首次观察到细胞质脂滴。在出生后的第一周，它们的数量和大小增加。弹性生成按以下顺序进行：oxytalan纤维（17天胎儿）、elunin纤维（1天大的大鼠）、弹性纤维（5天大的大鼠）。还观察到随机取向的单个微原纤维和微原纤维束（oxytalan纤维）之间的中间阶段。
