Human synoviocytes proliferation assay. (a) Pictures of cells at experimental times: 24, 48, 72, and 96 h; the proliferative properties of HCC were compared to the single H-HA and untreated synoviocytes (UT-S). (b) Cell growth curves were obtained through Image-Pro Plus 1.5 software (Media Cybernetics).
