胰岛素分泌细胞所产生的干细胞
纽约(路透社健康) -结果最近的实验提供"确切的证据"显示,在人类胚胎干细胞,可用于产生细胞分泌胰岛素的反应葡萄糖,像β -细胞在胰腺。
"Development of a cell therapy for diabetes would be greatly aided by a renewable supply of human beta-cells," Dr. Emmanuel E. Baetge and colleagues, from Novocell Inc. in San Diego, comment in the research journal Nature Biotechnology. "开发一个细胞治疗糖尿病,将极大地借助于一种可再生的供应人β -细胞, "博士灵光体育贝特格和他的同事,从novocell公司在圣迭戈,评论研究Nature杂志上的生物技术。
In the study, the researchers show that pancreatic tissue, derived from human embryonic stems cells, can generate cells that are "morphologically and functionally similar" to beta-cells after being implanted into mice.在这项研究中,研究人员发现胰腺癌组织中,来自人类胚胎干细胞,能产生细胞,是"形态和功能上类似的" β细胞后,植入小鼠。
In addition, the team goes on to show that implantation of the stem cell-derived tissue stops glucose levels rising excessively in the animals.此外,工作队下去,以证明植入的干细胞衍生的组织站血糖水平上升过多,在动物。
These findings suggest that human embryonic stem cells could, in fact, represent a renewable supply of insulin-producing cells for treating diabetes, the researchers conclude.这些研究结果表明,人类胚胎干细胞,而在事实上,代表着一种可再生的供应量产胰岛素细胞移植治疗糖尿病,研究者总结。
