Human multipotent embryonic stem cell-like progenitor cells

摘要

The invention provides a plurality of embryonic stem cell-like progenitor cells, which are isolated from a human tissue by a systemic screening of human mesenchymal stromal stem/progenitor cells and a cell sorting by a cell antigen selected from the group consisting of CD34, CD117, CD133, CD201, GloboH and combination thereof, and cultured in a medium supplemented with at least one or more steroids and one or more growth factors. The cells of the invention express CD34 and exhibit sphere-like clonogenicity in early passages and express multipotent embryonic stem cells (ESCs) like characteristics.

主权项

1. A method for producing an enriched population of multipotent human CD34+ mesenchymal common progenitor cells (CD34+ MCPCs), further having at least the following characteristics: CD14+, CD117+, CD133+ (AC133+), CD201+, Nestin+, SSEA3+, SSEA4+ and GloboH+, the method comprising:
isolating from a human somatic tissue by a systemic screening of human mesenchymal stromal stem/progenitor cells followed by a cell sorting by a cell antigen of CD34, wherein the human somatic tissue is selected from the group consisting of amnion, endometrium and gingival; and culturing in a medium comprising EGF and hydrocortisone or a medium comprising bFGF and EGF.
