Major interest of our team is to use stem cell technology to treat various cardiovascular diseases.

Stem Cells

 • We develop and use different bone marrow-derived stem or progenitor cells for cardiovascular repair

             o Bone marrow-derived multipotent stem cells (BMSC)

             o Endothelial progenitor cells

             o Mesenchymal stem cells

             o Hematopoietic stem cells

• Target diseases

             o Cardiac diseases: Myocardial infarction, chronic heart failure

             o Peripheral vascular disease; PAOD (peripheral artery obstructive disease) etc

             o Diabetic neuropathy

             o Lymphedema

             o Wound (wound healing)

• We investigate embryonic stem cells

             o differentiate into endothelial cells, cardiomyocytes, lymphatic vessels

             o therapeutic potential in the target diseases

• We recently started to combine technologies of biomaterial and stem cells for cardiac repair

Mechanistically, we are interested in angiogenesis, lymphangiogenesis, and cardiomyogenesis

Diabetes related research

• We work on the role of angiogenesis in diabetic complications such as heart failure, PAOD and diabetic    neuropathy

• We investigate functional defects of stem or progenitor cells in diabetes

             o Currently we are studying ROS-related targets

• We are developing a strategy to rescue this impairment

Research achievements

Development of novel bone marrow-derived stem cells and demonstration of successful therapeutic effects in myocardial infarction (J Clin Invest, 2005)

Role of host cells in therapeutic effects of adult stem cells (J Exp Med, 2007)
