The result showed that it is more easier to culture tissues and cells from embryo at mediat-anaphase than the other three, for it isolated more tissues and cells adhered to the bottom of bottle and which could survive more longer, moreover, the combination made up of a copy of Grace, a copy of MM medium and 20%FBS would maitain the time of growth of tissues and cells adhered to bottom live for longer time than other conbinations, especially the time of growth of tissues and cells from embryo at mediat-anaphase adhered to bottom could maitain above two monthes. Thus, we had optimized culturing conditions for tissues and cells from small brown leaf hopper. The different result of culture of these four tissues from small brown leaf hopper and the different form of cells indicated that the expression of genes was different in these four tissues.

In 1997, Bonnet reported that CD34+ CD38- cells of acute myeloid leukemia cells have the stem cell characteristics. Even though they accounted for only 0.2 percent of the total number of cells, but they are only oncogenous cells group in the SCID rat. In 2003, Singh SK found that CD133 + cells group, which are only a small number of the total cell number of the brain tumor cells, can form tumor cell balls in serum-free culture and CD133- cells group didn''t. In the next year, they found that the CD133 + cells group of the brain tumor cells, which were transplanted into NOD/SCID mouse''s brain, can cause brain tumors. But the CD133- cells group didn''t. After 2006, more and more studies showed that CD133+ group cells is closely related to tumor stem cells. Suetsugua, Ricci-Vitiani L and O''Brien CA showed that they isolated CD133 + cells group from the hepatoma cell line Huh-7 and colon cancer tissues, respectively. And they proved that the cells group were tumor stem cells.
寻找肿瘤干细胞的表面分子标记，一直是研究的热点。1997年，Bonnet等研究发现，人急性粒细胞白血病(acute myeloid leukemia，AML)中的CD34+CD38-亚群细胞，虽然仅占总数的0.2%，但是唯一可在免疫缺陷鼠具有成瘤性的细胞；2003年，Singh SK等发现脑肿瘤细胞在无血清培养中仅占总细胞数少数的CD133+群细胞可形成肿瘤细胞球，而CD133-群细胞不能形成，在第二年他们又发现CD133+群细胞移植到NOD/SCID鼠脑内，可诱发脑肿瘤，但CD133-群细胞却不能。2006年后，研究发现越来越多的肿瘤干细胞与CD133+群细胞有关，Suetsugua从肝癌细胞株Huh-7中，Ricci-Vitiani L和O''Brien CA分别在结肠癌组织中均分离出CD133+细胞，并证明该群细胞为肿瘤干细胞。
