有些研究表明，阻止细胞死亡在髓性白血病发生中其重要作用，且基因转化可局限于祖细胞：

β-catenin和Wnt路径的失调在癌症中很普遍，该途径的靶向过表达可以导致转基因鼠发生肿瘤：

总结：
1，自我更新是正常组织或肿瘤中干细胞的标志性特点；2 l6 c* g5 z/ N, a
2，在造血系统，长期自我更新细胞局限于少数长期HSC和一些淋巴细胞，其他细胞类型无自我更新潜能；
3，长期存在的细胞更可能累计突变从而导致肿瘤形成。因此，导致髓性白血病的基因改变必定发生在长期HSC或其获得自我更新能力的后代上。白血病患者中，长期HSC细胞中常有白血病相关异位现象，该现象强烈支持白血病突变常常在HSC中累积，导致某些淋巴瘤的突变可能在淋巴细胞中累积，从而使其具有长期自我更新能力；1 h$ e3 P  ?: K" U8 [. [
4，其他正常组织也具有自我更新能力的干细胞，如上皮，实体肿瘤发展过程中基因改变的逐步累积也发生在干细胞或其具有自我更新能力的后代上；
5，不同组织中，有不同信号途径控制干细胞的自我更新。但在个别组织中，普通干细胞和肿瘤细胞通过同一信号途径控制细胞增值，例如，WNT途径调节血液和上皮中干细胞的自我更新，但在有些上皮细胞癌中，也同样有WNT信号通路的激活；
6，理解了信号途径在普通干细胞和肿瘤细胞中的作用，有助于利用普通干细胞再生药物和鉴别出肿瘤干细胞的靶点从而为开发抗肿瘤药物服务；
7，大部分肿瘤组织中有肿瘤干细胞的存在，它们可以无限制的自我更新，而大部分干细胞仅具有有限的增值潜能；
8，为了治愈癌症，必须杀死肿瘤干细胞。为此，必须鉴别出该类细胞的特性。
