日本熊本大学一个研究小组最新报告称,他们利用实验鼠胚胎干细胞(ES细胞)高效培养出分泌胰岛素的胰岛细胞,将其移植到患糖尿病的实验鼠体内后,获得了满意的疗效,这一技术未来可能造福糖尿病患者。

此前,研究人员已尝试过利用胚胎干细胞培养分泌胰岛素的胰岛β细胞,但未能取得理想的结果,只能培养得到胰岛前体细胞(成为胰岛β细胞之前的一种细胞形态)。

研究小组为了找到胰岛前体细胞分化成胰岛β细胞时的必要物质,全面筛查了胰岛前体细胞的约1100个分子,发现了可以增加胰岛素分泌的2个分子。研究人员据此掌握了将胚胎干细胞(ES细胞)培养成胰岛β细胞的“秘密”,培养出的胰岛β细胞拥有和正常细胞匹敌的胰岛素分泌能力。

研究人员将培养出的胰岛β细胞移植到患有糖尿病的实验鼠体内,6周后实验鼠的血糖基本下降到了正常值。

为重度糖尿病患者移植胰岛细胞是一种有效的疗法,不过胰岛细胞提供者不足。利用胚胎干细胞(ES细胞)或诱导多功能干细胞(iPS细胞)培养胰岛细胞将有望扩大糖尿病移植疗法的机会。研究负责人粂昭苑说,在验证这项疗法的安全性等之后,希望10年内投入实用。

相关研究论文已刊登在15日的《自然·化学生物学》杂志上。

生命是如何适应陆地生活的发展史长期以来困惑着生物学家们——恐龙的后代,如何从鳍进化成手臂和腿的?鱼的器官肺是如何进化的? 生物学家们已经知道了心脏和肺如何适应陆地生活的进化史,主要通过心脏的功能和肺的气体交换的功能相耦合。肺是在哺乳动物进化过程中最后形成的一个器官,对于地球上的生命可以说是最重要的器官。 在胚胎发育过程中阐明了心脏和肺这两个系统的细胞是如何协调发展的。最初原始的肺的祖细胞可以伸

Nature & Science:科学家为克隆胚胎干细胞“突破”辩解

随着科学界对胚胎干细胞“突破性成果”的质疑,继在接受英国《自然》杂志采访后,论文作者又通过另一著名学术期刊《科学》杂志辩解:论文确实有错,但对研究结果无影响,论文快速发表或是因为《细胞》杂志担心论文消息泄漏。 一周前,美国俄勒冈州健康和科学大学国家灵长类研究中心舒赫拉特·米塔利波夫等人在《细胞》杂志网络版上发表论文称,通过向剔除细胞核物质的卵细胞内植入皮肤细胞,成功培育出了人类胚胎干细胞。但后来

美胚胎干细胞论文被疑作假

  美国一研究小组近日在《细胞》杂志发表论文称,成功培育出了人类胚胎干细胞。但很快就有读者指控论文存在“图片重复使用”等问题。《细胞》杂志已证实正在对此事件进行调查。  据美国《科学》杂志网站22日报道,遭受质疑的是美国俄勒冈州健康和科学大学国家灵长类研究中心米塔利波夫领导的研究小组。他们5月15日在《细胞》杂志上发表论文称,通过向剔除细胞核物质的卵细胞内植入皮肤细胞,成功培育出了人类胚胎干细胞。

Nat Biotech:胚胎干细胞成功使失明小鼠恢复视力

视网膜存在两种感光细胞:视锥细胞与视杆细胞,失去感光细胞是造成大量退行性疾病病患视力下降的“罪魁祸首”。 现在,伦敦大学学院科学家的使用实验鼠的胚胎干细胞,在人造视网膜帮助下,不仅在实验室培育出了眼部的感光细胞,而且将其移植进失明老鼠的眼部后让老鼠“重见光明”。这项刊登在《自然·生物技术》杂志上的最新研究,标志着人们向使用干细胞治疗失明又近了一步。 研究人员表示,最新研究的突破在于,他们已经证

诱导多能干细胞技术可以将普通的体细胞重编程为具有与胚胎干细胞类似的分化潜能的细胞,也就是说获得的诱导多能干细胞具有分化成为体内绝大多数种类细胞的能力。与这一技术密切相关的细胞移植也已经被认为是治疗部分遗传病,器官损伤以及神经退行性疾病等的重要潜在手段。而建立该技术的科学家也凭此获得了2012年度诺贝尔生理或医学奖。为了更好更快地将这一技术应用到疾病治疗中,中国科学院广州生物医药与健康研究院一直致力
