Dr. Marco Seandel's research interests focus on the influence of extrinsic signals in mediating normal stem cell and tumor cell fate in mammals, using the male germline stem cell as a model system. Novel genetic approaches have been implemented to identify and prospectively track primitive germ cell populations in the adult testis of both mice and humans, using a combination of in vitro and in vivo systems. The molecular mechanisms by which such stem cells preserve the ability to switch to a pluripotent state are being investigated. Normal male germline stem cells exhibit striking phenotypic similarities to adult human germ cell tumor, the pathogenesis of which is also a major emphasis of the research.
