Yaoliang Tang MD, PH.D We propose to replenish the stem cell pool for heart repair, by isolating and expanding cardiac stem cells from heart in vitro, infusing them systemically back in vivo post myocardial infarction, and recruiting them to the ischemic myocardium using SDF-1?/CXCR4 signal pathway.
We propose to develop a practical and important role for microRNAs in human heart disease, and understand the miRNA control network in differentiation of stem cells to cardiomyocytes.
We propose to reprogram cells from adult human tissue like skin to induced pluripotent stem cells (iPs), which appear to have all the properties of embryonic stem cells. Their use could be tailored made for each patients. We will study these cells and see if they are appropriate for human use in heart diseases.
We are developing a novel strategy to repair older infarcted hearts with young endothelial progenitor cells (EPCs). We want to investigate whether myocardial ischemia in older hearts can be better solved by combining a cardiac specific, hypoxia-regulated SDF-1? vector system with young EPC transplantation.
