Distinct alternative splicing patterns of mediator subunit genes during endothelial progenitor cell differentiation

► Identification and analysis of a novel MED12 transcript lacking exon 16 (MED12S). ► Identification and analysis of a novel MED19 transcript retaining intron 2 (MED19AS). ► They are expressed in peripheral blood mononuclear cells and nonadherent CD133+ cells. ► They are downregulated in cultured progenitor cells and Haec.
