Unerupted permanent bovine incisors studied by routine autoradiography using radioactive proline incorporation revealed collagen formation within the giant tubules situated in the incisal dentin. A high [3H]-proline labeling was seen within the pulpal vascularized portion of the giant tubules, as well as in association with groups of cells immediately incisal to the blood vessel loops. The incisal portion of the giant tubules showed no or insignificant [3H]-proline labeling.
通过使用放射性脯氨酸掺入的常规放射自显影术研究未萌出的恒河牛切牙，结果显示在切牙牙本质中的巨大管内有胶原蛋白形成。在巨大管的牙髓血管化部分以及与紧邻血管袢切端的细胞群相关处可见高[3H]-脯氨酸标记。巨大管的切端部分未显示或仅有微不足道的[3H]-脯氨酸标记。
