| Research Abstract |
The purpose of this study is to evaluate the safety and property of the activated nucleus pulposus cells after the cryopreservation. With the animal model and human material, we compared safety and property of the nucleus pulposus cells, ordinarily activated, to those in two subgroups on cryopreservation method ; 1) activated nucleus pulposus cells after cryopreservation for two weeks and 2) nucleus pulposus tissue itself after cryopreservation for two weeks. There was no significant difference amongst those three subgroups on the safety, the proliferation of the nucleus pulposus cells or the potentiality for the cell matrix in both animal and human materials. We confirmed cryopreservation of the nucleus pulposus is useful to repair various disc lesions.
