Endothelial cell production by programming
The invention generally regards methods for providing endothelial cells and precursors of endothelial cells from a variety of cell sources, such as pluripotent stem cells. Also provided are therapeutic compositions including the provided endothelial cells, and methods of using them for the treatment of subjects.
1. An isolated cell population comprising human endothelial cells, wherein at least 80% of the endothelial cells comprise an exogenous expression cassette that comprises one or more endothelial programming factor genes comprising a gene encoding ETV2 or an isoform thereof and/or ERG or an isoform thereof.
2. An isolated cell population comprising human endothelial progenitor cells, wherein at least 80% of the endothelial progenitor cells comprise an exogenous expression cassette that comprises one or more endothelial programming factor genes comprising a gene encoding ETV2 or an isoform thereof and/or ERG or an isoform thereof.
3. The isolated cell population of claim 1 or 2 , wherein said endothelial cells or progenitors express an ETV2, ERG, and/or isoforms thereof polypeptide encoded by said expression cassette.
4. The isolated cell population of claim 1 or 2 , wherein said endothelial cells or progenitors express an ETV2, ERG, and/or isoforms thereof RNA encoded by said expression cassette.
5. The isolated cell population of claim 1 or 2 , wherein the endothelial cells or progenitors express an ERG or an isoform thereof.
6. The isolated cell population of claim 5 , wherein the ERG or isoform thereof is ERG isoform 3.
7. The isolated cell population of claim 1 or 2 , wherein the endothelial cells or progenitors express an ETV2 or an isoform thereof.
