Abstract
A hydrogel biomaterial that can be utilized as a nucleus pulposus replacement material is described. The hydrogel biomaterial can is an elastin-glycosaminoglycan-collagen composite hydrogel biomaterial that can mimic the biochemical and functional characteristics of the human nucleus pulposus. Methods for forming the hydrogel biomaterial are also described as are methods for use of the hydrogel biomaterial, one of which is as an in vivo nucleus pulposus replacement material, another of which is a scaffolding material for use in nucleus pulposus tissue engineering applications.
