Sheltagen Medical develops human bone tissue for implantation in patients with bone fractures or spinal instability. The product is patient specific, using the patients own bone cells and blood components so that the transplant will not be rejected by the patients body. Sheltagen Medicals methodology for bone production in the laboratory involves autologous bone cells seeded on inorganic matrix, cultured in media containing self-blood serum, and exposed to mechanical stimulation by vibration.
