Yang Lab Research

Dr. Yang's laboratory investigates the fundamental cellular and molecular processes of myocardial restoration. Specifically, innovative therapeutics are translated using multi-modality imaging strategies. Novel cellular biologics are integrated with in vivo molecular and cellular imaging to generate high sensitivity with exquisite spatial and temporal resolution to characterize the salvage of myocardial injury and understand the mechanism of action. Dr. Yang is a PI on NIH/NHLBI funded Cardiovascular Cell Therapy Research Network (CCTRN) UM1 grant, which is designed to conduct multi-center clinical trial on novel stem cell therapy. He has focused on advancing the translation of iPSC-derived cardiomyocytes (iCMs) and investigating their therapeutic potential. In addition, he is a PI on 2 NIH, 1 CIRM, and 3 industry-sponsored research study or clinical trial grants. He received prior funding from CIRM, AHA, NIH K23, NIH K18, and NIHR01 to develop and translate novel stem cell biology, employing advanced in vivo imaging tools. He also directs the Stanford Cardiovascular MRI Program and Cardiovascular Stem Cell Laboratory. This lab employs in vitro and in vivo platforms of myocardial injury, advanced laser beam systems, and novel cellular and molecular imaging technologies to pursue an exceptionally focused investigation of the effects of exosomes on the injured myocardium. The laboratory has established a seamless workflow to generate iPSCs, differentiate into iCMs, and investigate the therapeutic role of iCMs reliably both in vitro and in vivo. These exosomes will create a  paradigm shift across all medical disciplines. The exosomes from the patient-specific iPSC-derived cells will treat many degenerative disorders by triggering and augmenting endogenous repair.
