A pharmaceutical composition of a hedgehog protein which is characterized in that the hedgehog protein is bound to a hydrophilic carrier that is biocompatible and biodegradable wherein the carrier is a polymer which - binds the hedgehog protein as a negatively-charged carrier as a result of ionic interactions, - does not denature the hedgehog protein when it binds to the carrier, - contains at least 0.1 to 2 negatively-charged residues per monomer under neutral conditions, - contains the charge in the form of acidic groups, - has an average molecular weight of at least 50,000 Da - and contains no agarose reversibly and actively releases hedgehog proteins in vivo from a carrier in a delayed manner. |
