随着干细胞研究的不断深入 ,人们对胚胎干细胞 (ES)、造血干细胞等干细胞了解日益加深。发现干细胞与肿瘤细胞有许多共性 ,如无限增生能力、迁移能力及在某些条件下能相互转化。提出肿瘤起源于干细胞、肿瘤中存在肿瘤干细胞等学说。这些学说的理论依据多来源于对造血系统肿瘤的研究。 With the deepening of stem cell research, people are getting more and more profound understanding of stem cells (ES), stem cells and other stem cells. Stem cells and tumor cells found that there are many common features, such as immortality, migration and under certain conditions can be transformed into each other. Proposed the origin of cancer stem cells, tumor stem cells exist in the theory. Most of the theoretical basis of these theories comes from the study of hematopoietic tumors.
