为了探讨太空微重力对鸡胚前庭感觉上皮细胞的形态发育的影响 ,选取在航天飞机 (STS-2 9)发育鸡胚和地面发育鸡胚各两只 ,利用计算机显微测量技术分别测量椭圆囊和球囊的毛细胞、支持细胞核的切面面积、周长、形状系数。太空发育鸡胚的球囊支持细胞核的切面面积、周长显著大于地面组 ,形状系数无差异 ;太空发育鸡胚的椭圆囊支持细胞核的切面面积、周长、形状系数以及椭圆囊和球囊毛细胞的切面面积、周长与地面发育鸡胚相比无明显差异。微重力可能对球囊支持细胞核的体积发育有影响 ,对椭圆囊和球囊的毛细胞以及椭圆囊支持细胞核的形态发育无影响。
In order to investigate the effect of space microgravity on the morphological development of chicken vestibule sensory epithelial cells, two chick embryos and two chick embryos on the ground were selected in the space shuttle (STS-29), and the cyst was measured by computer microscopy And the balloon hair cells, supporting the nucleus of the cross-sectional area, perimeter, shape factor. The cross-sectional area and perimeter of the nuclei supporting the nuclei of the embryos in space-developed chicken embryos were significantly larger than those in the ground groups, and there was no difference in the shape coefficients. The cross-sectional area, perimeter, shape factor, Cell cross-sectional area, perimeter and ground development of chicken embryos compared with no significant difference. Microgravity may have an impact on the volume development of the balloon-supported nuclei and have no effect on the morphological development of the oval and balloon hair cells and the oval-sac supportive nuclei.
