Several years ago, Schwartz then identified SRF as the only transcription factor required for sarcomere formation. Recently, Schwartz turned his attention to directed trans-differentiation of somatic cells to cells of other lineages, offering a new avenue for stem cell replacement therapy. Schwartz' research team explored the role of mammalian ETS1/2 and Mesp homologues of cardiogenic transcription factors of Ciona intestinalis, to convert primary human dermal fibroblasts into cardiac progenitors. Co-expression of both Ets2 and Mesp1, successfully reprogrammed human skin fibroblasts into cardiac progenitors, as shown by the de novo appearance of core cardiac transcription factors, gap junction proteins, sarcomeric proteins, electrical activity, and contractility. ETS2 and Mesp1 sit at the pinnacle of the cardiopoiesis regulatory hierarchy. Generating cardiac progenitors from fibroblasts is one of the most important milestones in contemporary biology. These efforts will help to identify other optimal cell types such as human adipogenic stem cells for such therapy and are designed to overcome technical and ethical issues involved in using embryonic stem cells. Ultimately, to reconstitute a human heart, the vision is to grow these engineered cells on artificial biomatrices and to treat diseased human hearts.  Publications/Creative Works Click here to search for this faculty member's publications on PubMed.  Affiliations  Research Consortia Gulf Coast Cluster for Regenerative Medicine  Appointments Title Department / School Institution Hugh Roy and Lillian Cranz Cullen Distinguished Professor Biology and Biochemistry University of Houston
