Our work aims at defining conditions for the isolation, expansion, and induction of differentiation of EPCs. The work focuses on the identification of genes specifically expressed at early stages of endothelial differentiation and definition of the EPC phenotype. Transcription factors and other relevant genes associated with endothelial specification will be identified and eventually used to induce and manipulate endothelial differentiation.
