    RESEARCH INTERESTS

    Dr. Yen is interested in the characterization of placenta-derived multipotent cells (PDMCs), a population of multipotent progenitor cells isolated and best characterized by her laboratory. In addition, she is interested in translational research of stem cells, using such stem cells including PDMCs, bone marrow mesenchymal stem cells, and embryonic stem cells. Her clinical research interests include postmenopausal women's health.

    RESEARCH ACTIVITIES & ACCOMPLISHMENTS

    The major focus of Dr. Yen's basic science research centers around finding alternative sources of human stem cells. Current sources of stem cells include embryonic stem cells (ESCs) and adult stem cells (ASCs). However, concerns exist with either source: ESCs, with its significant ethical considerations, tumorigenicity concerns, and paucity of cell lines; and ASCs, which are possibly more limited in potential. Dr. Yen's team has isolated a population of multipotent cells from the human term placenta, a temporary organ with fetal contributions that is discarded postpartum. Her laboratory is the first to isolate human placenta-derived multipotent cells (PDMCs) with multilineage differentiation capabilities of all three germ layers. Recent findings from her team have shown that these cells also possess strong immunosuppressive effects, properties which should be crucial for clinical use. Further characterization shows endothelial differentiation from PDMCs, which possess no endothelial progenitor cell markers. The ultimate goal of Dr. Yen's research is to use PDMCs – an ethically uncontroversial, easily accessible, and high-yield source of multipotent cells - in clinical applications.
