四种不同种属晶状体上皮细胞的原代培养及生长特性

Primary culture and growth characteristics of four different species of lens epithelial cells

目的:探索大鼠、兔、犬及人四种不同种属晶状体上皮细胞(lens epithelial cells,LECs)的原代培养条件,并观察其生长特性。方法:采用不同方法取出四种晶状体囊或前囊组织,改良组织块法进行原代培养,并在倒置显微镜下观察四种LECs的形态学特征及变化。结果:大鼠、兔、犬及人四种LECs均可采用改良组织块贴壁法进行原代培养。随着种属级别的升高,LECs贴壁能力逐渐增强,细胞由不规则的多角形向卵圆形发展、胞核渐渐圆润、胞浆越来越丰富,经多次传代后四种LECs均有向纤维化发展的趋势。结论:成功改良了大鼠、兔、犬及人LECs的原代培养方法,在细胞及分子水平为白内障及其相关领域的研究提供了技术支撑。

AIM ： To explore the primary culture conditions for four kinds of lens epithelial cells（ LECs） of rat,rabbit,dog,and human,and measure their growth characteristics.METHODS： The lens capsule or anterior capsular tissue of rat,rabbit,dog and patient were removed by different methods,and they were cut into tiny pieces for primary culture by modified tissue adherent method. The morphological features of four kinds of LECs were observed under an inverted microscope.RESULTS： Four kinds of LECs of rat,rabbit,dog and hum an could be cultured primarily by tissue adherent method. With the evolution of tissue source, the adherent capacity of LECs gradually strengthened,cells form were changed from irregular polygon to oval,nucleus rounded and cytoplasm enriched gradually. Four kinds of LECs had fibrotic changes after several passages. CONCLUSION： LECs of rat,rabbit,dog and human can be prim arily cultured. This method lays the foundation for them echanism research of caratact andrelated fields on the cellular and molecular levels.
