比较了兔耳软骨膜和肋骨在体内和体外的软骨化潜能。软骨膜作为游离自体移植物转移到头皮上的皮下组织中，并作为游离体转移到膝关节中。6周后检查移植物中软骨的存在。将兔耳软骨膜和肋骨软骨膜的体外外植体置于器官培养系统中。在1-3周后分析软骨的存在。在体内和体外，来自肋骨的兔软骨膜似乎比来自耳朵的软骨膜具有更大的软骨潜力。体外实验证实软骨膜内有软骨发生。
The cartilaginous potential of the rabbit ear perichondrium was compared to that of the rib in vivo and in vitro. Perichondrium was transferred as free autologous grafts to the subcutaneous tissue on the scalp and as loose bodies into the knee joint. The presence of cartilage in the grafts was examined after 6 wk. In vitro explants of rabbit perichondrium from the ear and the rib were maintained in an organ culture system. The presence of cartilage was analyzed after 1-3 wk. Rabbit perichondrium from the rib appeared to have a greater cartilaginous potential than that from the ear in vivo and in vitro. Chondrogenesis in perichondrium was demonstrated in vitro.
