摘要 目的:观察低氧/复氧和间歇性低氧时少突胶质前体细胞(O2A)增殖的影响。方法:取混合培养4d的胶质细胞。按实验分为低氧/复氧、间歇性低氧和常氧3组,低氧/复氧组细胞置低氧环境(3%O2)中分别培养1h、2h、3h、4h、8h、12h、24h、48h和72h后取出,恢复常氧培养至9d。间歇性低氧组每天上午定时将细胞置于低氧环境中分别培养1h、2h、3h、4h后取出。恢复常氧培养。每天一次,分别重复1~4次后。常氧培养至9d。然后同时取出各组细胞,进行O2A细胞的分离纯化和细胞计数。结果:低氧/复氧1h、2h、3h组和间歇性低氧1h、2h、3h组,O2A细胞数均较常氧组明显增多。结论:低氧/复氧和间歇性低氧都可促进体外培养的O2A细胞明显增殖。其机制尚有待于进一步研究。
