| Research Abstract |
The aim of the present study was to investigate the sensory mechanism from osteoblasts to sensory neurons in co-culture system using MS of osteoblasts. The result indicated that MS of the osteoblast elicited afferent P2X receptor-mediated purinergic transmission to sensory neurons in all stages of a mouse development. Ultrastructural observation of the contact between the neurite and the osteoblast supported this finding. This afferent transmission varied with aging. Satellite cells may have protective actions on sensory neurons and could modulate this transmission.
