CaSR effect on F-actin ring formation of OCs. (A,B) Four groups of OC precursor cells were treated with CM from modified A549 cells co-cultured with macrophages to examine potential OC differentiation induction. Immunofluorescent staining was used to evaluate F-actin ring formation of OCs. The average area of F-actin ring of OCs was detected and calculated using 400-fold microscope and ImageJ software (NIH). The average area of F-actin ring of OCs in CaSR overexpression group was significantly higher than that in empty vector and negative control groups (p < 0.001). The difference between negative and empty vector control groups was not statistically significant (p > 0.05). **p < 0.01, ***p < 0.001.
