The colony-forming unit and proliferation of MSCs. (a) Representative photograph of colonies in CFU-A at day 7. (b) Number of CFU detected per 106 of seeded cells in CFU-A. (c) Average diameter of CFU. (d) Average number of cells per colony in CFU-A. (e) Cell proliferation was measured by WST-1 assay. The optical density (OD) value of normal MSCs was used as 100% cell proliferation. The data were drawn from three independent experiments and the results were expressed as mean ± SD. versus N Group. versus O Group.
