Expression of hematopoietic, endothelial, stemness and adhesion molecules on LESCs.

The expression of different groups of surface antigens on the LESCs was compared to those found on bmMSCs. A small population of the LESCs expressed higher CD14, CD117/c-kit, CXCR4 which are markers of special progenitor cell types. Although the LESCs expressed most of the MSC-like markers, just a minor population expressed CD90/Thy-1 and CD105 which determine the MSC phenotype. BmMSCs lack CD49f/Itg α9 which is strongly expressed on LESCs (the data represent percentage of positive cells within the total LESC culture shown as mean ± S.D., n = 7; p
