Figure 2. Cell authentication through immunofluorescence staining and FCM.
The upper panel (A–C) showed cells were respectively stained with Ig-FITC (isotype control), CD90-APC, and CD45-FITC. The lower panel (D–F) showed immunophenotypes of bMSCs analyzed by FCM; >87.82% cells were positive for CD90; and >80% were negative for CD45. Scale bar, 50 μm.
