Cell surface marker expression and proliferation potential of L-ADSCs and O-ADSCs. a Cell surface marker expression of L-ADSCs and O-ADSCs. b Phase contrast images of L-ADSCs and O-ADSCs at day 1, day 2 and day 3. Scale bar, 50 μm. c Cell proliferation potential was measured by CCK8 kit (n ≥ 3). d Represent images of β-gal staining of L-ADSCs and O-ADSCs (left panel) and quantification of β-gal positive cells in total L-ADSCs or O-ADSCs. At least six representative visual fields for each were counted. Scale bar, 50 μm. **P < 0.01; ***P < 0.001 compared to L-ADSCs
