Research: Mr. Tchao is currently studying cardiomyocyte differentiation from rat and human origin skeletal muscle derived stem cells (MDSCs) by exogenous expression of cardiac transcription factors and the effects of deacetylase inhibition on functioning cardiomyocyte differentiation from MDSC within a 3D collagen gel bioreactor. 

Currently, Mr. Tchao has completed all required training of biochemical assays and is currently running the experiments solo. For exogenous cardiac transcription factor induction of MDSCs. He has succeeded in gene transfection using retroviral vectors. He found that single gene transduction (Tbx5 or GATA4 cardiac transcription factor) has not significantly improved functioning cardiomyocyte differentiation. Therefore, he will pursue transfection of multiple genes. Deacetylation by trichostatin A increases cardiac protein expression and improves force generation in MDSC-derived engineered cardiac tissue.
