PCA reduced bone absorption. (a) BMMs were grown in Osteo Assay Surface plates for 4 days (magnification ). (b) Absorption area per well. (c) RAW264.7 cells were grown in Osteo Assay Surface plates for 7–8 days (magnification ). (d) Resorption area per well. (e) TRAP staining of osteoclasts differentiated from BMMs on Corning CaP-coated plates (magnification ). (f) Number of osteoclast per well. (g) Analysis of the absorption area per osteoclast-like cell. Absorption pits were quantified using ImageJ software. and # compared with the group treated with RANKL alone.
