Mean percentages of human MSCs that are labeled with each of the 25 markers, as determined by flow cytometry.

Among the 25 mean percentages, 24 fulfilled or were close to fulfilling Dominici's criteria to define human MSCs as being positive or negative for a given marker*. Only one mean value (13.72% for CD71) had slight deviation from Dominici's criteria. If CD71 was considered to be absent, our result show that CD14, CD31, CD34, CD45, CD49d, CD49f, CD51, CD54, CD71 CD106, CD133, MHC II, cytokeratin and desmin are absent from human MSCs, whereas CD13, CD29, CD44, CD59, CD73, CD90, CD105, CD166, MHC I, α-SMA, and vimentin are present on human MSCs.*Dominici's criteria: a cell sample is positive for a given marker if more than 95% of cells express the marker, whereas it is negative if less than 2% of cells express the marker [1].Mean percentages of human MSCs that are labeled with each of the 25 markers, as determined by flow cytometry.
