  Calcium phosphate resorption activity of PBMC cultures. Cell cultures were performed in absence (base medium) or presence of recombinant M‐CSF and RANKL (positive control), or supplemented with conditioned media from foetal skin fibroblasts (CM1), adult skin fibroblasts (CM2) and adult gingival fibroblasts (CM3). (a) Representative images of calcium phosphate layers after cell removal. (b) Quantification of resorbed areas expressed as percentage of total area. *Significantly different from positive control. #Significantly different from cultures performed in base medium. Three independent experiments were performed for each condition.
