Abstract

Tissue culture and banking is used to guard against the spread of transmittable diseases. In one disclosed example, living nucleus pulposis cells obtained from recently deceased human or animal donors are used to restore disc function and eliminate pain in patients with disc disease. In the preferred embodiment, the donor nucleus is morselized to allow insertion through a small puncture in the annulus fibrosis with a needle and syringe. Although the description makes specific reference to human disc cells, the invention may be used as a way to provide disease-free disc tissue derived from animal sources, and is applicable as well to other types of biologic tissues and materials such pancreas cells, cartilage cells, and so forth. Additional therapeutic substances like culture medium, growth factors, differentiation factors, hydrogels polymers, antibiotics, anti-inflammatory medications, or immunosuppressive medications could be added to the transplanted cells or tissue.
