本论文采用不同肿瘤干细胞培养体系逐步筛选适合肝癌结肠癌干细胞样细胞培养的 新型培养体系,将各种肿瘤干细胞培养液编为A1、A2、B1、B2、C1、C2、C3。实验结 果表明B1为适合结肠癌干细胞样细胞培养的新型培养体系,而Bl,CI,C3为适合肝癌干细 胞样细胞培养的新型培养体系。肿瘤干细胞培养液A1、A2培养细胞时,A1干细胞培养液 培养的细胞不会形成悬浮细胞球体,A2干细胞培养液培养的细胞零散聚集或是细胞球体不 能连续传代;Bl、B2干细胞培养液中,B1肿瘤干细胞培养液培养的人肝癌细胞系Hep3B 细胞和人结肠癌细胞系SW620细胞具有球状体出现,与文献[21,22]@所报道的CSC形态类 似,检测的CSC标记基因均有高表达。人结肠癌细胞系SW620细胞来源的悬浮细胞球能 够连续传代下去,可连续培养两个月,保存建系。人肝癌细胞系Hep3B细胞来源的悬浮细 胞球能够连续传代一个月。利用Cl、C2、C3肿瘤干细胞培养体系培养人肝癌细胞系Hep3B 细胞和Huh7细胞,用C1、C3培养两天后传代,传代后第二天发现细胞悬浮,并聚集成 球状体细胞较透亮,再次传代后仍有细胞聚集,与受精卵发育到四细胞期、八细胞期似的 聚集,部分细胞死亡部分细胞生长,悬浮细胞球体能够连续传代下去,并检测CSC标记基 因均有高表达,保存建系。
passage.In stem cell culture medium B 1 and B2,human hepatoma cell line Hep3B and human colon cancer cell line SW620 both had suspending cell sphere only using stem cell culture
sphere for 2 months from human colon cancer cell line SW620,we established the cell line.The suspending cell sphere from human hepatoma cell line Hep3B could serially passage for one month.Thus we used stem cell culture medium C 1,C2 and C3 to culture human hepatoma cell line Hep3B and Huh7.We discovered that those cells were suspending,could grow into sphere.Although many cells would be died,those cells could form sphere again after passage. We detected the cancer stem cell maker gene highly expressing and established the cell lines.
stem cell culture medium A1 could not form suspending cell sphere,but stem cell culture medium A2 made cells loosely aggregate together or form suspending cell sphere without
recrudescence,through it we have profound recognition of tumor and improve cancer tatargeting
therapy.People further research the biological character and the special maker gene of cancer

肝癌、结肠癌干细胞样细胞新型培养体系及其细胞系建立的研究
摘要
干细胞是一类具有自我更新和增殖分化潜能的原始细胞,这种细胞能分化为特定组织 中一个或者多个具有特定功能的终末细胞。成体干细胞的主要生物学特征是自我更新和增 殖分化形成新生成熟组织,与恶性肿瘤细胞的生长繁殖、转移扩散以及放化疗后的再生复 发十分相似。根据干细胞的这种生物学特性和恶性肿瘤在临床上的生物学表现,近年来提 出在肿瘤的瘤体内也存在与干细胞具有相似生物学活性的一类细胞群体,科学家命名这种 存在于肿瘤细胞群体中的特殊细胞为肿瘤干细胞(cancer stem cell),或称之为肿瘤起始细胞 (tumor initiating cell,T.Ic)。最近几年报道的大量的资料表明,大多数肿瘤细胞群中存在肿 瘤干细胞,它在肿瘤发生、发展、转移和复发中起关键作用。它可能从根本上改变人们对 肿瘤的认识,是肿瘤治疗新靶标的希望所在【l】,因此人们对其生物学特性及其特异标记基 因深入研究。本课题就是采用不同的培养体系在肿瘤细胞中分选培养肿瘤干细胞样细胞, 检测肿瘤干细胞标记基因的表达情况。

system for human colon cancer stem—like cells and B 1,C 1,C3 are the suitable novel culture systems for human hepatoma cancer stem-like cells.The cancer cells which were cultured with
marker gene expression in those cells.
The paper using different stem cell culture mediums gradually screen a novel culture system, which can enrich cancer stem cells.We named the different stem cell culture mediums A l,A2, B 1,B2,C 1,C2,and C3.The experimental results indicate that B I is the suitable novel culture
the foundation for subsequent experiment. Key words:cancer stem cell,stem cell culture medium,suspending cell sphere,marker gene

The experimental results indicate that we established three novel culture system for cancer stem..1ike cells and sorted and cultured the cancer stem--like cells from cancer cell lines using
propagation,metabasis,extension and recrudescence after radiotherapy and/or chemotherapy of

Recently,more and more datas indicate that cancer stem cell exist in most cancer cell population, and the cancer stem cells play a critical role in tumorigenesis,development,metabasis,

Abstract
Stem cells are defined as initial cells that have the ability to self-renewal and the potential to proliferate,differentiate,which can generate one or many end cells with certain function of a particular tissue through differentiation.That is also the main biological character of adult stem cell,and the adult stem cell will form new mature tissue,which is similar to the growth,
