摘要

形态学和放射自显影资料表明，分泌发生在成牙本质过程水平，沿垂直于牙本质成熟轴的侧轴。用长春碱硫酸盐诱导的修饰强调了细胞周围空间(150- 200 nm)的重要性，而胶原纤维排列的紊乱表明存在流动。我们提出一个把所有这些事实联系起来的假设。

[Role of secretion in the dynamics of the maturation of predentin. Morphological, autoradiographic and freeze fracture study in the rat; changes induced by vinblastine].

Morphological and autoradiographic data give evidence that secretion take place at the odontoblast process level according to a lateral axis, perpendicular to the maturation axis of the predentine. Induced modifications with vinblastine sulphate emphasize the importance of the pericellular space (150--200 nm) while the disorganization of the collagen fiber arrangement suggests the presence of flows. We propose an hypothesis which connects all these facts.
