STM:未成熟的干细胞可修复肺损伤

2015-02-02 MedSci MedSci原创

目前,在急性肺损伤中存活下来的病人的肺部功能都可恢复,这意味着成人的肺组织可在某种程度上再生。根据不同肺损伤的成因或严重性,许多不同种类的始祖细胞都可成功帮助小鼠肺部再生,这些始祖细胞包括肺泡II型细胞以及气道末梢肝细胞。近日,Vaughan和他的团队发现未成熟的隐形内皮谱系始祖细胞(LNEP cells)可以恢复因流感病毒或博来霉素而引起的肺损伤。LNEP细胞在正常小鼠的肺末梢中是处于休眠状态的

目前,在急性肺损伤中存活下来的病人的肺部功能都可恢复,这意味着成人的肺组织可在某种程度上再生。根据不同肺损伤的成因或严重性,许多不同种类的始祖细胞都可成功帮助小鼠肺部再生,这些始祖细胞包括肺泡II型细胞以及气道末梢肝细胞。近日,Vaughan和他的团队发现未成熟的隐形内皮谱系始祖细胞(LNEP cells)可以恢复因流感病毒或博来霉素而引起的肺损伤。


LNEP细胞在正常小鼠的肺末梢中是处于休眠状态的,并且它们不会表达包括CC10蛋白和肺表面活化蛋白C(SPC)在内的成熟谱系标记。可是,研究人员证明了LNEP细胞会在肺损伤后移动到损伤部位帮助肺部重建。Vaughan等研究员使用细胞谱追踪以及细胞移植的方法发现LNEP细胞是一种多能细胞,它们可以分化成俱乐部细胞(club cells)和 肺泡细胞,但成熟了的内皮谱系细胞并没有这个功能。

有趣的是,尽管大量Notch信号可以活化LNEP细胞,但如果Notch信号停留时间过长会导致小鼠出现蜂窝肺,这意味着残留的Notch信号会抑制肺泡细胞的分裂从而导致肺组织再生失败。同时,他们在患有特发性肺纤维化和肺硬化的病人中得到的肺中发现了过分活跃的Notch信号以及蜂窝性囊肿,这证实了不同的Notch信号会影响模拟LNEP人类肺始祖细胞的分化。这个实验证明了调节Notch信号以及LNEP细胞的活化程度可以帮助减缓人类肺纤维化的成长。

干细胞">干细胞技术产业化是韩忠朝最后一项事业,这位2014年国家科技进步奖一等奖得主,最希望的是中国能有在国际上有一席之地的干细胞高科技企业。“现在就想怎么样架一座桥,把自己的、别人的一些好的科研成果,转化成科技产品、社会效益”。 1月9日,国家科学技术奖励大会在北京人民大会堂举行。中国医学科学院北京协和医学院教授、国家干细胞工程技术研究中心主任韩忠朝与军事医学科学院联合完成的“成体

Stem Cell Rep:自身干细胞可以治疗痴呆症

近日,来自鲁汶大学的研究人员通过研究开发出了治疗遗传性痴呆症的新型疗法,文章中研究人员将病人机体的干细胞转化成为受痴呆影响的神经元细胞,在携带易致痴呆突变的病人机体的干细胞中,研究者发现了一种可以抑制正常神经发育的靶向性缺失,而当这种缺失被修正后,这些干细胞就会回归正常状态,相关研究刊登于国际杂志Stem Cell Reports上。 研究者Catherine Verfaillie表示,利用

STM:基因改造过的诱导性多功能干细胞(iPSCs)可治疗隐性遗传营养不良型大疱性表皮松解症(RDEB)

隐性遗传营养不良型大疱性表皮松解症(RDEB) 是一种遗传疾病。它是由于VII型胶原的编码基因变异导致的。RDEB患者的皮肤很脆弱并且很容易在接收到压力时起水疱。特别是对于RDEB这种在现阶段没有有效治疗的疾病,使用诱导性多功能干细胞(iPSCs)有从根本上改变疾病细胞治疗的潜力。为了证明诱导性多功能干细胞(iPSCs)可以治疗RDEB,研究者们从有VII型胶原基因(Co17a1)变异的小鼠中提取

Science:癌症干细胞,癌症泰斗的豪赌

麻省理工的Robert Weinberg是世界上最著名的癌症生物学家之一。他发现了第一个人类癌基因Ras和第一个抑癌基因Rb,其杰出工作已经成为肿瘤研究领域乃至整个医学生物学领域的重要里程碑。“我在这一行已经四十年了,我们研究的许多东西最终在临床上都没什么用,” Weinberg说。但现在,这位72岁高龄的癌症泰斗重新乐观起来。 据Science介绍,Weinberg为一个大胆的癌症理论赌上了

EMA批准干细胞治疗产品 用于眼角膜疾病治疗

根据汤森路透Bioworld报道,EMA首次为干细胞治疗药品的上市亮起了绿灯,这也是EMA连续第三年在药品的年度审批通过量上呈现增加态势。虽然2014总共获批的药物有82个,仅比2013年的81个多1个,但是对比于2012年的57个,应该可以说是显著增加。第一个被EMA批准通过的干细胞治疗药物名为Holoclar,该药物被推荐用于治疗由严重眼部化学或物理灼伤引起的眼角膜干细胞缺失,由意大利制药公司

美科学家希望借干细胞靶向药物消灭癌症

Robert Weinberg是当今世界最有名的癌症生物学家之一,他在区分标志癌症发展的基因方面曾做出先驱工作。他见证过来来往往各种癌症疗法带来的希望。“无论好坏,我在这个领域已经工作了40年。但我们过去做过的许多工作已经在临床上被证明是没有用的。”如今迈入古稀之年,已是72岁高龄的他重新恢复了乐观。“这是我真正意义上第一次处于研发一种或多种有效试剂的岗位上,这些疗法将真正惠及癌症患者。”
