multi fate stem cell mesenchymal stem cell Many but not all mesenchymal cells derive from the mesoderm. MSCs are reportedly CD3-negative, CD4-negative, CD5-negative, CD8-negative, CD11a-negative, CD11b-negative, CD14-negative, CD19-negative, CD29-positive, CD31-negative, CD34-negative, CD38-negative, CD40-negative, CD44-positive, CD45-negative, CD49-positive, CD54-positive, CD66b-negative, CD79a-negative, CD80-negative, CD102-positive, CD106-positive, CD117-positive, CD121a-positive, CD121b-positive, CD123-positive, CD124-positive, CD133-negative, CD146-positive, CD166-positive, CD271-positive, B220-negative, Gr1-negative, MHCI-positive, MHCII-negative, SSEA4-negative, sca1-positive, Ter119-negative, and glycophorin A-negative. Cultured MSCs are capable of producing stem cell factor, IL7, IL8, IL11, TGF-beta, cofilin, galectin-1, laminin-receptor 1, cyclophilin A, and MMP-2. connective tissue cell
