Abstract
Abstract A BMP carrier is described for use with humans and animals. The carrier includes human hair and a block copolymer of ethylene glycol and propylene glycols that can be implanted into an intervertebral disc space with the polymer in liquid form and then changing into a solid viscoelastic state. The copolymer can be a carrier for BMP. The carrier also includes processed human hair.
