A method for ex vivo production of a three-dimensional bone implant adapted for implantation to a patient, implants produced by such a method, and uses of such implants. The method comprises disposing differentiated osteoblasts on a matrix support comprising at least one of collagen, calcium phosphate, calcium sulfate and tricalcium phosphate; contacting the differentiated osteoblasts on the matrix with autologous blood serum from the patient, comprising at least one of a growth factor and a cytokine; and disposing the differentiated osteoblasts on the matrix support and the medium in a bioreactor, in which production of the bone implant is performed.
