Effect of Autogenous Marrow and Calcitonin on Reactions to a Ceramic

The effect of autogenous marrow and calcitonin on reactions to a tricalcium phosphate ceramic was studied by subcutaneous implantation in rats. No bone formation was evident in association with uncoated and calcitonin-coated ceramic. At four weeks and thereafter bone formation was evident in association with all marrow-coated implants.
