An acellular bioresorbable ultra

Immunohistochemical (IHC) staining using an anti-alginate antibody showed that alginate was present in the IVDs at 4 weeks after surgery but that it had disappeared by 12 weeks after implantation in the rabbit model (Supplementary Fig 8a) and by 24 weeks after implantation in the sheep model (Supplementary Fig 8b) These results suggest that UPAL gel is a bioresorbable biomaterial
