他让干细胞研究起死回生哺乳动物的发育是从受精卵开始的。受精卵一分二,二分四……这样不停分裂下去,就形成了早期胚胎。组成早期胚胎的细胞彼此毫无差别,我们称其为干细胞,因它们处于胚胎中,又称胚胎干细胞。到胚胎发育晚期,干细胞就开始朝专职化的方向发展:有的发育成神经细胞,有的发育成皮肤细胞……如此等等,这个过程叫干细胞的分化。
He let the stem cell research back to life Mammals develop from fertilized eggs. Fertilized eggs in two, two four ... ... so stop splitting, it formed the early embryo. The cells that make up the early embryos are indistinguishable from each other, and we call them stem cells because they are in the embryo, also known as embryonic stem cells. To the late stage of embryonic development, stem cells began to develop in the direction of full-time: Some develop into nerve cells, and some develop into skin cells ...... So, this process is called stem cell differentiation.
