Regulation of mesodermal specification
Disclosed is a method to differentiate stern, progenitor or precursor cells comprising contacting said stem, progenitor or precursor cells with miR-130a, or an RNA having at least 95% identity thereto, so as to yield cells of endothelial lineage. Further disclosed are compositions comprising the endothelial lineage cells obtained and methods of using the compositions for treating diseases including cardiovascular diseases.
1. A method to differentiate cells comprising over-expressing miR-130a in Flk1 + /Pdgfra low hemato-endothelial progenitors or Fkl1 + /Pdgfra + mesodermal precursor cells, or nucleic acid having at least 95% identity miR-130a, so as to yield cells of endothelial lineage, wherein the nucleic acid is RNA.
2. The method of claim 1 , wherein the cells are mammalian cells.
3. The method of claim 1 , further comprising admixing the endothelial lineage cells with a pharmaceutically acceptable carrier or a cell culture medium.
4. The method of claim 1 , wherein cells administered to the subject are autologous or allogeneic.
5. A composition comprising Flk1 + /Pdgfra low hemato-endothelial progenitors or Fkl1 + /Pdgfra + mesodermal precursor cells overexpressing mir-130a and a carrier.
6. The composition of claim 5 , wherein the cells are mammalian.
