0引言肿瘤干细胞(tumor stem cell,TSC)是一种增殖特性失控、可形成肿瘤、具有干细胞特性的细胞[1]。TSC学说认为TSC是形成不同分化程度肿瘤细胞和肿瘤增长、复发及转移的根源[2]。本文就近年来TSC生物学特性及相关研究进展作简要综述。1TSC生物学特性1.1强大的增殖分化潜能细
0 Introduction Tumor stem cells (TSCs) are cells with proliferative properties that can form tumors and have stem cell properties [1]. TSC doctrine that TSC is the formation of different degrees of differentiation of tumor cells and tumor growth, recurrence and metastasis [2]. This article briefly reviewed the biological characteristics of TSCs and related research progress in recent years. 1TSC biological characteristics 1.1 powerful proliferation and differentiation potential
