Retention time of NPs in hBMSCs.

Notes: (A) hBMSCs were treated with PLGA-SA and PS/hpGHA NPs that were labeled with FITC for 6 hours, and then washed out. Fluorescence images show NPs in hBMSCs after treatment for 0, 6, 12, and 24 hours (blue = DAPI, green = PLGA-SA or PS/hpGHA NPs) (scale bar =20 µm). (B) Retentions of PLGA-SA and PS/hpGHA NPs obtained from fluorescence intensity (*P<0.05, **P<0.01, ***P<0.001).

Abbreviations: hBMSC, human bone marrow mesenchymal stem cells; NP, nanoparticle; PLGA, poly (lactide-co-glycolide); PS, poly (lactide-co-glycolide)-stearylamine; SA, stearylamine.
