FACS analyses indicate similar cell surface antigen profiles of MSC from different age groups. Cells were labeled with fluorescent antibodies for Sca-1, CD44, CD11b, and CD45 and analyzed by FACS. Consistent with a mesenchymal phenotype, all cells were positive for the markers Sca-1 and CD44 (>99% and 98% respectively). Cells were negative for the monocyte marker CD11b and the hematopoietic lineage marker CD45 (<2%).
