Figure Lengend Snippet: ADSC-EV uptake by osteoblasts. The hFOBs ( A ) and hOBs ( B ) were treated with CM-DiI-labeled ADSC-EVs at concentrations of 0 (Control: control group) or 1 × 10 9 particles/mL (EVs: EV group) for 5 days, and images at days 1 and 5 were obtained using a camera under confocal microscopy. Cell nucleus, blue fluorescence stain; cytoplasm, green fluorescence stain; and CM-DiI-labeled ADSC-EVs, red fluorescence stain.

Figure Lengend Snippet: Effect of ADSC-EVs on the survival of osteoblasts. The hFOBs ( A ) and hOBs ( B ) were treated with ADSC-EVs at concentrations of 0 (Control: control group) or 10 9 particles/mL (EVs: EV group) for 5 days and analyzed for survival. Live/dead cell assays were performed for hFOBs and hOBs to determine the cell survival on days 1 and 5. Green fluorescence indicates live cells (Live), whereas red fluorescence indicates dead cells (Dead). The hFOBs and hOBs remained alive on days 1 and 5 after the ADSC-EV treatment.

Figure Lengend Snippet: Effect of ADSC-EVs on the proliferation of osteoblasts. The hFOBs ( A ) and hOBs ( B ) were treated with ADSC-EVs at concentrations of 0 (Control: control group) or 1 × 10 7 –1 × 10 9 particles/mL (EVs: EV group) for 5 days and analyzed for cell proliferation. MTS assays were performed for hFOBs and hOBs on day 5 to determine the cell proliferation. Cell proliferation of hFOBs and hOBs was enhanced after the ADSC-EV treatment. Data are presented as the mean ± SD ( n = 6). * p < 0.05 and ** p < 0.01 for comparisons with the control group. # p < 0.05 and ## p < 0.01 for comparisons between the two groups.

Figure Lengend Snippet: ADSC-EVs promoted osteogenic marker gene expression in osteoblasts. The hFOBs ( A ) and hOBs ( B ) were treated with ADSC-EVs at concentrations of 0 (Control: control group) or 10 9 particles/mL (EVs: EV group) for 5 days. The mRNA expression levels of the osteogenic marker genes (runt-related transcription factor 2 ( Runx2 ), osteocalcin ( OC ), collagen type I ( Col-I ), and alkaline phosphatase ( ALP )) of hFOBs and hOBs were measured. Gene expression levels are expressed relative to the control group, which is defined as 1. Data are presented as the mean ± SD ( n = 3). * p < 0.05 and ** p < 0.01 for comparisons with the control group.

Figure Lengend Snippet: ADSC-EVs promote ALP activity, calcium deposition, and collagen type I ( Col-I ) synthesis in osteoblasts. The hFOBs ( A ) and hOBs ( B ) were treated with ADSC-EVs at concentrations of 0 (Control: control group) or 1 × 10 9 particles/mL (EVs: EV group) for 12 days and analyzed through von Kossa staining, Alizarin red S staining and quantification, and ELISA for ALP activity and Col-I synthesis. Data are presented as the mean ± SD ( n = 3). * p < 0.05 and ** p < 0.01 for comparisons with the control group.
