【摘要】 目的:探讨成体羊心室心肌细胞增殖与死亡的方式及规律。方法:12只山羊取心脏后,常规石蜡切片,HE染色,光学显微镜观察。结果:正常成体羊心室心肌细胞,包括工作心肌细胞和传导心肌细胞,均可见明显的无丝分裂相和细胞死亡特征。结论:正常成体羊心室心肌细胞存在增生和死亡的动力学过程,且羊心室心肌细胞增殖的主要方式是无丝分裂。更多还原

【Abstract】 Aim: To explore the proliferative and senescent pattern of adult goat ventricular muscle cells. Methods:The paraffin sections of hearts from 12 goats, stained with HE, were observed under light microscope. Results: The obvious amitotic phases and cellular senescent characteristics were observed in adult goat ventricular muscle cells including working and conducting cardiac muscle cells.Conclusion: The dynamic process of proliferation and senescence occurres in normal adult goat ventricular muscle cells. The goat cardiomyocytes are proliferated mainly with an amitotic way.更多还原
