摘要
目的:比较组织块法和胶原酶两步灌流法制备大鼠原代肝细胞的产量、活率和活力。方法:通过荧光倒置显微镜观察大鼠原代肝细胞的形态,并且分别通过台盼蓝染色和MTT法测定制备得到的原代肝细胞产量、活率和活力。结果:组织块法和胶原酶两步灌流法制备大鼠原代肝细胞的产量分别为(0.30±0.10)×108个/肝和(0.67±0.11)×108个/肝,活率分别为(65±14)%和(88±16)%,组织块法制备大鼠原代肝细胞的活力比胶原酶两步灌流法更低,且活力下降快。结论:胶原酶两步灌流法制备的大鼠原代肝细胞比组织块法产量更高、活率和活力均更好,更适用于体外药物代谢的研究。
Object: To compare the different of output, living rate and vitality between tissue block method and two steps collagenase perfusion method for preparation ratshepatocytes. Mothod: Observe the shape of rat hepatocytes by fluorescent inverted microscope, and determine the output, living rate and vitality of rats hepatocytes by Trypanblue stainand MTT assay respectively. Results: The output of rats hepatocytes prepared by tissue block method and two steps col lagenase perfusion was (0.30 ±0.10)x 108 per liver and (0.67 ±0.11)x 108 per liver, respectively. The living rate was (65 ±14)% and (88 ±16)%, respectively. The vitality of rats hepatocytes prepared by tissue block method was lower than that by two-step collagenase perfusion method and the vitality down faster. Conclusion" The output of rats hepatocytes prepared by two-step collagenase perfusion method was higher than that by tissue block method, as well as living rate and vitality. Two-step collagenase perfusion method is more suitable for the in vitro drug metabolism study.
