Overview of Research Interests:

  • Reprogramming of somatic cells to generate induced pluripotent (iPS cells) or multipotent stem cells and its therapeutic potential in regenerative medicines;
  • Study the mechanisms of reprogramming by histone deacetylation and DNA methylation;
  • Use of embryonic and adult stem cells in cardiovascular and lung vascular repair and regeneration.
