刺激触发获得全能性(stimulus-triggered acquisition of pluripotency,STAP)显示了一种新的基因重编程理念,是一种制备干细胞的新策略。STAP细胞可分化成皮肤细胞、肌肉细胞等多种细胞。与iPS细胞相比,STAP细胞没有外源基因导入,不仅制备方法简单,似乎也比iPS细胞更加安全。环境刺激,如酸、碱、机械损伤、热、旱(渴)等,在某种情况下可诱导基因重编程,导致细胞 The stimulus-triggered acquisition of pluripotency (STAP) shows a new concept of gene reprogramming and is a new strategy for preparing stem cells. STAP cells can differentiate into skin cells, muscle cells and other cells. Compared with iPS cells, STAP cells have no foreign gene introduction and are not only simple in preparation method, but also appear to be safer than iPS cells. Environmental stimuli, such as acids, alkalis, mechanical damage, heat, drought (thirst), etc., under certain circumstances can induce gene reprogramming, resulting in cells
