Abstract
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 purified collagen matrix material derived from natural collagen-containing animal tissue, a collagen-free porous bone mineral matrix material derived from natural bone having a crystal structure substantially that of natural bone and being substantially free from endogenous organic material, or a combination of purified collagen matrix material and porous bone mineral matrix material.
