But latest figures show the highest proportion of smears signalling the most seere pre - cancerous change and immediate precursor to cerical cancer , known as cin3 , are in young women 但最新数据表明预示最严重癌前病变和宫颈癌前体细胞即cin3 ，在年轻女性中所占比例最高。
In addition , the immediate elf - emf exposure might induce cell cycle arrest , thus also contributing to its stimulating effect of neurogenesis from mesencephalic neural progenitors 此外， elf emfs抑制中脑神经前体细胞增殖，加速神经前体细胞退出细胞分裂周期，可能也是elf
Transformed , oncogenic precursors , possessing both defining neural - stem - cell properties and the ability to initiate intracerebral tumours , have been identified in human brain cancers 人类脑部肿瘤中已经证实，突变的致瘤前体细胞不仅具有神经干细胞性能并且能致脑部肿瘤发生的潜能。
It was reported that the growth cone of xenopus embryonic neurons might response to a 7mv / mm electric signal and extend to the cathod ; also , neuronal differentiation was enhanced in the existence of electromagnetic field Cntf和il一1a对中脑神经前体细胞神经元向分化的效应与浓度有关： cntf0
They directed the stem cells into becoming what they believe are hemangioblasts , the blood vessel precursor cells , although other teams will have to replicate this for it to be accepted 他们指定干细胞分化成他们相信就是成血管细胞，血管前体细胞，尽管其他的研究小组必须复制这个过程来使它被接受。
Massachusetts - based advanced cell technology said it had devised a straightforward way to make blood vessel precursor cells out of the stem cells and plans to test them in humans 立足于麻萨诸塞州的高级细胞技术院说他们发明了一条直接的方法将血管前体细胞直接从干细胞中分离并且计划在人身上测试它们。
Here we report that bone morphogenetic proteins ( bmps ) , amongst which bmp4 elicits the strongest effect , trigger a significant reduction in the stem - like , tumour - initiating precursors of human glioblastomas ( gbms ) 本研究我们报告骨形成蛋白4最大程度的降低人类恶性胶质瘤干细胞样致瘤前体细胞的致瘤作用。
Rather than injecting undifferentiated stem cells into damaged tissue , using precursor cells from a later stage of development - - ones already “ programmed ” to become retina or some other type of cell - - may be more successful , he says 不是通过注射未分化的干细胞进入损伤组织，使用来自发育后期的前体细胞（已经程序化成为视网膜或其他种类的细胞）可能更成功。
Angiogenesis , the formation of new capillary vessels , is an essential step in tumor growth and matastasis . it has been thought that the angiogenesis is the migration and proliferation of existing endothelial cells within vascular endothelium 对于肿瘤血管生成，传统的观点认为是由已有血管通过出芽方式完成的；但最近的研究证实外周血中的血管内皮及其前体细胞的动员与募集，对肿瘤血管生成具有十分重要的作用。
Now it has been found the recruitment and homing of circulating endothelial cells ( cecs ) or their progenitors ( ceps ) released from the bone marrow is very important in tumor angiogenesis . we detected the cecs and ceps in 64 pb ( peripheral blood ) of tumor patients . we found the amount of cecs and ceps is higher in tumor patients than normal controls 本项目应用流式细胞法对64例肿瘤患者及15例正常人，外周血中的循环血管内皮细胞( circulatingendothelialcell ， cec )以及骨髓来源的循环血管内皮前体细胞( circulalingendothelialprecursor ， cep )进行了检测，证实了外周血中cec / cep的存在，发现肿瘤患者cec / cep含量高于正常对照组，提示肿瘤患者体内存在血管内皮及其前体细胞的动员。
