sRNA Induces the LARge-scale Transdetermination of Mesenchymal Stem Cells into Hematopoietic Stem Cells in Human.
Mesenchymal stem cells (MSCs) can differentiate into cells of bone, endothelium, adipose tissue, cARtilage, muscle, and brain. However, whether they can transdeterminate into hematopoietic stem cells (HSCs) remains unsolved. We report here that a subpopulation of human MSCs that ARe CD44+,CD29+, CD105+, CD166+,CD133-,CD34- could differentiate into hematopoietic stem cells (CD150+/CD133+/CD34+) and their descending blood cells in vitro, when transfected with new endogenous shRNAs The sRNA was high-effectively delivered into MSCs by a novel peptide means. These induced MSC-HSCs could form different types of hematopoietic colonies as nature-occurring HSCs did. Upon transplantation into sublethally irradiated NOD/SCID mice, these MSC-HSCs engrafted and differentiated into all hematopoietic lineages such as erythrocytes, lymphocytes, myelocytes and thrombocyte. More importantly, these induced HSCs could successfully engraft and effectively function in patients with severe aplastic anemia. Furthermore, we demonstrated the first evidence that the transdetermination of MSCs was induced by acetylation of histone proteins and activation of many transcriptional factors. Together, our findings identify the sRNAs that dictates a directed differentiation of MSCs towARd HSCs and open up a new source for HSCs used for the treatment of blood diseases and ARtificial stem cell-made blood.

immunotherapy against cancers(position of sellulAR therapy)
MARgARet:细胞研究和治疗的监管标准
MARgARet教授就细胞研究和治疗的监管标准将何去何从发表了演讲。她详细介绍了地方标准政策在亚洲一些国家如中国、印度、泰国、马来西亚和越南等的不同模式,并提出科学家和企业需要更多的国际统一化标准来促进临床实验的进行,而不是出于国家地方保护而各自规定监管标准。
Yuji Heike:免疫治疗(治疗癌症的sellulAR位置)
国际癌症中心(NationalCancerCenter)的YujiHeike教授则带来了癌症的细胞免疫治疗方法。他认为今后组合疗法是癌症治疗的主流方法,并对癌症免疫疗法进行了详细介绍。以PD-1在肺癌中的免疫疗法为案例进行了详细阐述。最后他还号召全亚洲能够加入ACTO,共同合作研究。
Stefan LARsson:医生们可以互相学习
不同医院的不同手术有着不同的结果。但是病人不知道数据, 所以使得选外科医生成为了一个高风险的猜测游戏。
史帝芬·拉森(Stefan LARsson)研究了当医生开始衡量并分享他们的髋关节手术的结果时(比如说什么是最有效的方法)会发生的情况。
如果医生们可以相互学习并形成一个反馈循环,医疗保健会不会变得更好、更便宜?
Christopher deChARms:即时扫描大脑的技术
神经科学家和发明家Christopher deChARms展示一种新的方式利用功能磁共振成像显示大脑活动-思想,情感,痛苦-当它正在发生时。换句话说,你可以看到你的感受。
Dave deBronkARt:所有病人应彼此交流
当Dave deBronkARt了解到他得了一种罕见的晚期癌症,他在网上向和他一样的一群病人求助,并且找到了一种甚至他自己的医生都没听过的治疗方法。这救了他的命。 现在他号召所有的病人彼此交流,了解自身的健康数据,使医疗事业在每个e-病人的基础上变得更好。
MARcel Dicke我们为什么不食用昆虫呢
MARcel Dicke马赛·狄基希望把昆虫添加到人们的饮食中,他讲了增进人们食欲昆虫的案例。他还传递给挑剔的厨师与美食家的信息是:像蝗虫和毛虫的美味,在味道,营养,甚至在生态友好上可与肉类媲美。
