Figure Lengend Snippet: a , c Representative brightfield images of hFOB1.19 spheroids after 2 and 5 days of exposure to PFOA, respectively. Spheroids exposed to 0.02% of vehicle (DMSO) were used as the control. Images were obtained using the Light Lionheart FX Microscope. Scale bar = 200 μm (magnification 10×). b , d Morphological parameters of hFOB1.19 spheroids after 2 and 5 days of exposure to PFOA, respectively. ImageJ software determined area, solidity, circularity, and roundness after 2 and 5 days of exposure to different PFOA concentrations ( n = 31–40), individual biological replicates. P values indicate the results of comparisons between each PFOA-treated group and the control group. Values of p < 0.05 are considered statistically significant.

Article Snippet: The human osteoblast cell line hFOB1.19 (ATCC CRL-11372) was obtained from the American Type Culture Collection (ATCC, USA) in March 2021.

Figure Lengend Snippet: Western blot analysis of oxidative stress marker expression, a (60 kDa) CAT and b (96 kDa) NRF2 for 2D ( n = 5 biological replicates). c – e CAT levels in hFOB1.19 spheroids exposed to different PFOA concentrations for 2 days ( c ) and 5 days ( e ). NRF2 levels in hFOB1.19 spheroids exposed to different PFOA concentrations for 2 days ( d ) and 5 days ( f ) ( n = 3–4 individual biological replicates). P values indicate the results of comparisons between each PFOA-treated group and the control group. Values of p < 0.05 are considered statistically significant.

Figure Lengend Snippet: Western blot analysis of COL1A2 and CB1 levels. a , b (120 kDa) COL1A2 and (53 kDa) CB1 respectively for 2D ( n = 5 individual biological replicates). c – e Degraded COL1A2 (60 kDa) levels in hFOB1.19 spheroids exposed to different PFOA concentrations for 2 and 5 days, respectively. d , f CB1 levels in hFOB1.19 spheroids exposed to different PFOA concentrations for 2 and 5 days, respectively ( n = 3–4 individual biological replicates). P values indicate the results of comparisons between each PFOA-treated group and the control group. Values of p < 0.05 are considered statistically significant. g Localization of CB1 on the osteoblast membrane on the spheroid surface. Scale bar: 20 μm.
