Chan Lab

Sunny ChanSunny Chan, PhDWelcome to the Chan lab! Congenital heart defects and muscular dystrophies are common hereditary diseases affecting children, but effective treatments for most of these disorders are scarce. In our lab, we are working on deciphering the molecular regulation of how these diseases develop and establishing stem cell-based therapies to combat them.

Current Lab Projects

Heart Project:
Heart ProjectTo understand the role of the transcription factor Mesp1 in cardiac and skeletal myogenic development. Mesp1 was once thought as a master regulator of cardiovascular specification. But our previous work revealed a much more broader role, in which Mesp1 promotes hematopoietic, cardiac and skeletal myogenic differentiation in a context dependent manner. We are currently studying how Mesp1 regulates cardiac and skeletal myogenic development and its role in congenital heart defects and muscular dystrophies.

Skeletal Muscle Project:
Muscle-projectTo develop novel strategies for producing adult stem cells from pluripotent stem cells. Adult stem cells are endogenous, multipotent stem cells with unparalleled potency in regenerating tissues they normally reside. Muscle stem cells are such example. We have recently developed a method to produce muscle stem cells from pluripotent stem cells with exceptional regenerative capacity. We are currently expanding our method to model and to treat muscular dystrophies.
