Methods and compositions for the clinical derivation of an allogenic cell and therapeutic uses
View Patent ↗Various cells, stem cells, and stem cell components, including associated methods of generating and using such cells are provided. In one aspect, for example, an isolated cell that is capable of self-renewal and culture expansion and is obtained from a subepithelial layer of a mammalian umbilical cord tissue. Such an isolated cell expresses at least three cell markers selected from CD29, CD73, CD90, CD166, SSEA4, CD9, CD44, CD146, or CD105, and does not express at least three cell markers selected from CD45, CD34, CD14, CD79, CD106, CD86, CD80, CD19, CD117, Stro-1, or HLA-DR.
1. An isolated cell prepared by a process comprising:
placing a subepithelial layer of a mammalian umbilical cord tissue in direct contact with a growth substrate; and
culturing the subepithelial layer such that the isolated cell from the subepithelial layer is capable of self-renewal and culture expansion,
wherein the isolated cell expresses at least three cell markers selected from the group consisting of CD29, CD73, CD90, CD166, SSEA4, CD9, CD44, CD146, or CD105, and
wherein the isolated cell does not express NANOG and at least five cell markers selected from the group consisting of CD45, CD34, CD14, CD79, CD106, CD86, CD80, CD19, CD117, Stro-1, or HLA-DR.
2. The isolated cell of claim 1 , wherein the isolated cell expresses CD29, CD73, CD90, CD166, SSEA4, CD9, CD44, CD146, and CD105.
3. The isolated cell of claim 1 , wherein the isolated cell does not express CD45, CD34, CD14, CD79, CD106, CD86, CD80, CD19, CD117, Stro-1, and HLA-DR.
4. The isolated cell of claim 1 , wherein the isolated cell is positive for SOX2.
5. The isolated cell of claim 1 , wherein the isolated cell is positive for OCT4.
6. The isolated cell of claim 1 , wherein the isolated cell is positive for SOX2 and OCT4.
7. The isolated cell of claim 1 , wherein the wherein the isolated cell is capable of differentiation into a cell type selected from the group consisting of adipocytes, chondrocytes, osteocytes, cardiomyocytes, endothelial cells, and myocytes.
8. The isolated cell of claim 1 , wherein the isolated cell produces exosomes expressing CD63, CD9, or CD63 and CD9.
9. The isolated cell of claim 1 , wherein culturing comprises culturing in a culture media that is free of animal components.
10. A culture of differentiated cells derived from the isolated cell of claim 1 , wherein the culture of differentiated cells includes a cell type selected from the group consisting of adipocytes, chondrocytes, osteocytes, cardiomyocytes, endothelial cells, myocytes and combinations thereof.
11. The isolated cell of claim 1 that has been differentiated into an adipocyte cell.
12. The isolated cell of claim 1 that has been differentiated into a chondrocyte cell.
13. The isolated cell of claim 1 that has been differentiated into an osteocyte cell.
14. The isolated cell of claim 1 that has been differentiated into a cardiomyocyte cell.
15. The isolated cell of claim 1 that has been expanded into a cell culture.
