Song Lab

Translational Research in Cardaic Development & Disease

The goal of research in our lab is to understand mechanisms governing cardiac lineage commitment and pathogenesis of cardiomyopathies, which forms bases to develop therapeutic strategies for heart disease. We actively collaborate with scientists in the field with the long-term goal of improving human health.

News for Our Members:

Dr. Andrew Riching’s paper entitled with Suppression of canonical TGF-β signaling enables GATA4 to interact with H3K27me3 demethylase JMJD3 to promote cardiomyogenesis, published in the Journal of Molecular and Cellular Cardiology, has been selected as one of JMCC’s “Papers of the Year” of 2021. Andrew’s article was selected as one of 3 Original Research Papers of the Year from among nearly 200 articles published in JMCC in 2021 (https://www.sciencedirect.com/science/article/pii/S0022282822000049). Dr. Riching was a graduate student at Pharmacology Graduate Program.

We are recruiting scientists who are interested in regenerative medicine or translational research of cardiovascular disease. Welcome to join us!

Molecular mechanisms for decisions of cardiomyocyte fate.

Terminally differentiated fibroblasts and pluripotent stem cells can transdifferentiate or differentiate into cardiomyocytes. We attempt to unravel cellular and molecular mechanisms underlying the determination of cardiomyocyte cell fate. The goal is to design therapeutic strategies for heart regeneration. 

Laboratory models of cardiac development and disease.

We unravel molecular mechanisms governing heart development & disease. The goal is to search for potential cures by using induced pluripotent stem cells derived from heart disease patients and pre-clinical animal models.
