| 1 | Micromanaging cardiac regeneration:Targeted delivery of micro RNAs for cardiac repair and regeneration显示文摘The loss of cardiomyocytes during injury and disease can result in heart failure and sudden death, while the adult heart has a limited capacity for endogenous regeneration and repair. Current stem cell-based regenerative medicine approaches modestly improve cardiomyocyte survival, but offer neglectable cardiomyogenesis. This has prompted the need for methodological developments that crease de novo cardiomyocytes. Current insights in cardiac development on the processes and regulatory mechanisms in embryonic cardiomyocyte differentiation provide a basis to therapeutically induce these pathways to generate new cardiomyocytes. Here, we discuss the current knowledge on embryonic cardiomyocyte differentiation and the implementation of this knowledge in state-ofthe-art protocols to the direct reprogramming of cardiac fibroblasts into de novo cardiomyocytes in vitro and in vivo with an emphasis on micro RNA-mediated reprogramming. Additionally, we discuss current advances on state-of-theart targeted drug delivery systems that can be employed to deliver these micro RNAs to the damaged cardiac tissue. Together, the advances in our understanding of cardiac development, recent advances in micro RNAbased therapeutics, and innovative drug delivery systems, highlight exciting opportunities for effective therapies for myocardial infarction and heart failure. | Jan AAM Kamps Guido Krenning | 2016 | World Journal of Cardiology2016，8，2： | 6 |
| 2 | 诱导性多能干细胞技术用于研究人类疾病显示文摘获得遗传学上与患者相配的大量细胞是再生医学的梦想。诱导性多能干细胞技术通过在培养皿中培养细胞来研究发病机理,建立疾病模型,观察疾病的分子机制,并发现新细胞基础的药物。诱导多能干(iPS)细胞从非多能细胞诱导产生,但拥有相似于胚胎干(ES)细胞的多能性,Takahashi等[1-4]首先实现了这个突破,在体外成功表达4个转录因子,即Oct4、Sox2、Klf4和c-Myc,这个步骤不需要卵母细胞。 | 阮光萍 刘菊芬 姚翔 何洁 王金祥 杨建勇 庞荣清 潘兴华 | 2015 | 国际检验医学杂志2015，36，12： | 1 |
| 3 | Transitions between mesenchymal and epithelial states and the concomitant gene expression changes显示文摘Epithelial-mesenchymal transition(EMT),mesenchymal-epithelial transition(MET),and even the sequential EMT-MET can be observed during multiple cell fate conversions including cancer progression and embryonic development.In the current review,we first focused on the existence and beneficial roles of the sequential EMT-MET during three typical cell fate conversions,differentiation from pluripotent stem cells(PSCs)to neurons,de-differentiation from mouse embryonic fibroblasts(MEFs)to PSCs,and trans-differentiation from MEFs to neurons.We tried to provide some preliminary hypotheses to connect EMT-MET and cell fate conversions,like the possible contributions of the intermediate mesenchymal state to iPSCs generation and neurontrans-differentiation.The intermediate mesenchymal state during sequential EMT-MET was further discussed by exploring the conserved signatures on gene expression during a variety of EMT.Discussion on the interaction among vitamin C,DNA methylation,and EMT/MET was also provided. | LIANG LiNing SUN Hao LI LingYu ZHENG Hui | 2016 | Science Foundation in China2016，24，1： | 0 |
| 4 | Making cardiomyocytes with your chemistry set:Small molecule-induced cardiogenesis in somatic cells显示文摘Cell transplantation is an attractive potential therapy for heart diseases. For example, myocardial infarction(MI) is a leading cause of mortality in many countries. Numerous medical interventions have been developed to stabilize patients with MI and, although this has increased survival rates, there is currently no clinically approved method to reverse the loss of cardiac muscle cells(cardiomyocytes) that accompanies this disease. Cell transplantation has been proposed as a method to replace cardiomyocytes, but a safe and reliable source of cardiogenic cells is required. An ideal source would be the patients' own somatic tissue cells, which could be converted into cardiogenic cells and transplanted into the site of MI. However, these are difficult to produce in large quantities and standardized protocols to produce cardiac cells would be advantageous for the research community. To achieve these research goals, small molecules represent attractive tools to control cell behavior. In this editorial, we introduce the use of small molecules in stem cell research and summarize their application to the induction of cardiogenesis in noncardiac cells. Exciting new developments in this field are discussed, which we hope will encourage cardiac stem cell biologists to further consider employing small molecules in their culture protocols. | Woong-Hee Kim Da-Woon Jung Darren Reece Williams | 2015 | World Journal of Cardiology2015，7，3： | 0 |
