Proliferative and kinetic activity of chondrocytes in five sites of endochondral growth in the mid-line cranial base of the rat have been studied using a single injection of 3H-thymidine in animals aged 4-80 days. The marked caudorostral gradient and temporal gradient of the labelling index and labelling profiles is indicative of a proliferative activity specific to each endochondral growth site. Measurements of the growth rate indicate that each growth site in the cranial base bones has a specific growth rate.
在4至80日龄的大鼠中,通过单次注射3H-胸腺嘧啶核苷,研究了大鼠颅底中线软骨内生长五个部位软骨细胞的增殖和动力学活性。标记指数和标记曲线显著的尾-头梯度和时间梯度表明每个软骨内生长部位都有特定的增殖活性。生长速率的测量表明颅底骨骼的每个生长部位都有特定的生长速率。
