We evaluated possible differences in the capacity of calvaria and long bone osteoblasts to induce osteoclast formation.
Calvaria osteoblasts induce far more osteoclasts than long bone osteoblasts.
The ratio of RANKL/OPG was higher for calvaria osteoblasts than for long bone osteoblasts.
VitD3 pre-stimulation increased the capacity of long bone osteoblasts to induce osteoclastogenesis.
