8月7日,Nature杂志电,日本将建立诱导多能干细胞库。

由于研究瓶颈的挑战,伦理和法律上的障碍和企业投资的畏缩,干细胞疗法的进展一直非常缓慢。现在,干细胞研究的先驱,同时也是诱导多能干细胞的发明者,日本京都大学山中伸弥教授计划直接建立用于治疗用途的干细胞库。该干细胞库将存储几十个诱导多能干细胞(iPS细胞)系。此举将日本推向开拓生物医学技术的最前沿。

日本每年向8个iPS细胞疗法转化医学研究长期项目投资数百万美元,包括一项山中领导的,每年250万美元,京都大学iPS细胞研究和应用中心的帕金森氏症(CIRA)治疗研究项目。该计划离临床试验至少有三年。首次使用人类iPS细胞的临床试验,修复病变视网膜的尝试,计划明年在神户的RIKEN发育生物学中心进行。

诱导多能干细胞联合项目是山中长久以来的梦想。上个月,日本卫生部委员会决定允许从全国数以千计胎儿脐带血样本中建立细胞系。哈佛医学院的干细胞生物学家乔治·戴利说,山中存储细胞应用于医学临床的计划是"一个大胆的举动"。但一些研究人员怀疑iPS细胞技术是否已准备好作为临床应用。

山中的计划是,到2020年创建75个免疫耐受性良好的 iPS细胞系。80%的人口对这些细胞系不产生免疫排斥。要做到这一点,山中需要找到在三个编码人类白细胞抗原(HLAs)关键基因位点上具有两个相同拷贝的样本捐献者。据他计算,他将不得不从约64,000人中通过筛选样品,找到75个合适的捐赠者。

Stem-cell pioneer banks on future therapies

David Cyranoski

Progress toward stem-cell therapies has been frustratingly slow, delayed by research challenges, ethical and legal barriers and corporate jitters. Now, stem-cell pioneer Shinya Yamanaka of Kyoto University in Japan plans to jump-start the field by building up a bank of stem cells for therapeutic use. The bank would store dozens of lines of induced pluripotent stem (iPS) cells, putting Japan in an unfamiliar position: at the forefront of efforts to introduce a pioneering biomedical technology.
