对于研究细胞老化来说 ,红细胞是一个很好的模型 ,这是因为 :(一 )红细胞没有合成蛋白能力 ,故不可能对损伤进行修复 ;(二 )红细胞膜是它的唯一质膜 ,分离时不易造成污染 ;(三 )红细胞很容易获取。红细胞逐渐衰老而消亡的途径大约有两条 :一是自溶 ;二是被吞噬。但其原因均是细 Erythrocytes are a good model for studying cell aging because (i) erythrocytes do not have the ability to synthesize proteins and therefore are not likely to repair the damage; (ii) the erythrocyte membrane is its only plasma membrane, and when separated Not easy to cause pollution; (C) red blood cells is easy to obtain. There are about two ways to gradually red blood cells age and die: one is autolysis; the other is phagocytosis. But the reason is fine
