小鼠耳蜗内毛细胞的表面形态在出生时就已发育完全。在这个时候，一个有规律的拉长的微绒毛覆盖在耳蜗各级的外毛细胞表面。外毛细胞上的感觉毛在出生后的最初几天经历形态成熟。出生后5-7天达到成熟的表面形态。耳蜗毛细胞的成熟有两个梯度：从基底到顶端，从内毛细胞到第三排外毛细胞。外毛细胞上感觉毛的极化，即，感觉毛在径向方向上的极性分化，发生为面向血管纹的感觉毛的长度的逐步增加。
Surface morphology of inner hair cells in the cochlea of the mouse is fully developed at birth. At this time a regular pattern of elongated microvilli covers the surfaces of outer hair cells at all levels of the cochlea. Sensory hair on outer hair cells undergo a morphological maturation during the first days postnatally. A mature surface morphology is reached 5-7 days after birth. There are 2 gradients in hair cell maturation in the cochlea: basal to apical, and from inner hair cells to the 3rd row of outer hair cells. Polarization of sensory hairs on an outer hair cell, i.e., polar differentiation of the sensory hairs in the radial direction, occurs as a stepwise increase in length of those facing the stria vascularis.
