以往认为,肿瘤是南体细胞突变而成,每个肿瘤细胞都可以无限制地生长。但这无法解释肿瘤细胞似乎具有无限的生命力以及并非所有肿瘤细胞都能无限制生长的现象。肿瘤细胞生长、转移和复发的特点与干细胞的基本特性十分相似,因此,有学者提出肿瘤干细胞的理论,这一理论为我们 In the past that the tumor is a mutation of southern somatic cells, each tumor cells can be unlimited growth. But this does not explain the seemingly infinite vitality of tumor cells and the fact that not all tumor cells grow indefinitely.

Therefore, some scholars have proposed the theory of tumor stem cells, which is our theory
