Research Interests
By definition, pluripotent stem cells have the ability to proliferate indefinitely and to differentiate to any cell types of the human body, offering wonderful promise for human developmental biology, regenerative medicine and drug discovery. The most established type of pluripotent stem cells are human Embryonic Stem Cells (hESCs), that are isolated from excess human embryos from in vitro fertilization clinics. In our laboratory, Dr. Eric Chiao has derived a disease-specific hESC line from an embryo determined by pre-implantation to have inherited Marfan syndrome (MFS), a common autosomal dominant hereditary disorder affecting skeletal, ocular and cardiovascular systems.
Recently a new category of pluripotent cells derived by reprogramming of somatic cells to an embryonic state, named induced Pluripotent Stem Cells (iPSCs), have generated tremendous excitement. iPSCs have theoretically equivalent differentiation capabilities as traditionally derived hESCs cells. For the first time, researchers will be able to make pluripotent cell lines from families with inherited diseases and from patients carrying different types of genetic mutations without the use of surplus IVF embryos. Therefore, iPSCs represent a unique tool for in vitro modeling human disease and pharmaceutical screening.
The goal of my work is to improve our knowledge of MFS mechanism using hESCs and iPSCs derived from affected individuals. As thoracic aortic aneurysms are the greatest health risks associated with MFS, I have a special interest in developing in vitro differentiation assays towards cardiovascular cell fates.
