The DFCs, iDFCs and dDFCs express mesenchymal stem cell surface markers.

Abstract

<p>(A) iDFCs and dDFCs possess DFCs properties. iDFCs and dDFCs are both vimentin positive and ck14 negative just the same as DFCs. (B) DFCs, iDFCs and dDFCs express mesenchymal stem cell surface markers, i.e. CD73 (a) and CD105 (b), but lack the expression of CD34(c). The percentage of strol-1 positive cells is about 13%(d).</p
