A bioartificial nucleus pulposus is adapted for replacing at least a portion
of
a natural nucleus pulposus in an intervertebral disc. The bioartificial nucleus
pulposus includes an artificial support structure made from a biodegradable material.
The support structure has a plurality of pores. A carrier material is contained
in the pores of the support structure. A plurality of nucleus pulposus cells are
carried by the carrier material. A bioartificial intervertebral disc contains the
bioartificial nucleus pulposus.
