耳蜗毛细胞静纤毛束生后发育的实验研究

Experimental research of postnatal development of hair cell stereocilia bundles in cochlea

本文对一系列生后不同年龄小白鼠耳蜗毛细胞静纤毛束发育进行形态学观察、发现其发育过程基本呈现4个阶段、各阶段都伴数量、长度及交联结构等方面的变化,本结果有助于对哺乳动物毛细胞静纤毛形态发育及此过程中结构-功能关系的进一步理解。

A morphometric analysis of stereocilia bundles was carried out in an age-graded series of mice, and found the overall transformation of the bundles presented as a four-stage process. The stereo-cilia alteration of each stage is in number, length, and spatial relationships. The process of stereocilia bundles morphogenesis and relationships between structure and function during development have been discussed.
