中文摘要: |
目的:观察国人胚胎三叉神经节细胞分化及发育过程。方法:取水囊引产18-36 周国人胎儿三叉神经节,HE 染色及透射电镜
观察。结果:18-20 周胎儿三叉神经节神经元排列紧密,胞质少,可见到数量不多的线粒体,且其内几乎看不到嵴,其它细胞器少。
25 周时,线粒体嵴变长,粗面内质网雏形出现,有纵形小管出现;27 周时可观察到成熟的高尔基复合体,32 周后,线粒体、粗面内
质网等细胞器发育趋于成熟。到33 周电镜下可见溶酶体;36 周时细胞内各种细胞器结构和功能基本完善。结论:人胚胎三叉神经
节细胞发育过程中随胎龄增加,其结构和功能逐步完善,32~36 周(8~9 月)是细胞的分化发育重要时期。 |

Objective: To investigate the development and differentiation of human fetus trigeminal ganglion cells with the age
increased. Methods: Chinese human trigeminal ganglia were obtained from 18-36 weeks old abortion fetuses, and the ultrastructural
changes of cells were detected by using optical and transmission electron microscope. Results: After 18 to 20 weeks' development, the
neurons in the trigeminal ganglion cells tightly packed, with little cytoplasm and can observe a small number of mitochondria which is
barely seen the cristae, there were few other organelles, 25 weeks, mitochondria cristae became longer , rough endoplasmic reticulum
shape appeared, some showed a longitudinal tubules, the mature Golgi complex appeared at 27 weeks old fetus. After 32 weeks, the
development of mitochondria, rough endoplasmic reticulum and other organelles approached maturity; the lysosome can be seen under
electron microscope until 33 weeks; At 36 weeks, the structure and function of all kinds of intracellular organelles basically have
completely developed. Conclusion: The structure and function gradually improved with gestational age increased during human fetal
trigeminal ganglion cells development, 32 to 36 weeks (8 ~ 9 months) was an important period of cells differentiation and development. |
