The KSU Stem Cell Biotechnology Research team has been focused upon characterizing non embryonic stem cells that they have discovered in the umbilical cord matrix and rat embryonic stem cell. We lead this group and organize research efforts.
To date, our published work indicates a propensity for the nonembryonic stem cells to differentiate along the neural lineage (Mitchell et al., 2003) and for these cells to engraft following xenografting into rats that are not receiving immune suppression treatment (Weiss et al., 2004; Medicetty et al. 2004). Currently, my laboratory is characterizing the role of human and animal umbilical cord matrix stem cells to reverse the behavioral deficits found in a rat model of Parkinson's disease.

My laboratory has also isolated and characterized rat embryonic stem cells. These stem cells are pluripotent and will be used to generate preclinical rat models for studying a variety of diseases.
