A bone healing combination material includes a matrix carrying cultivated bone-forming cells which may be osteocytes, osteoblasts, stromal stem cells or stem cells committed to differentiation into bone-forming osteoblasts. The matrix is a porous bone mineral derived from natural bone, the mineral having a crystal structure substantially that of natural bone and being substantially free from endogenous organic substances. The matrix is either collagen-free or is combined with purified collagen material derived from natural collagen-containing animal tissue and consisting of collagen I, collagen III or a mixture thereof.
