The Honolulu Advertiser reports on the use of scaffolds in veterinary tissue engineering. "The matrix works like a three-dimensional scaffold and is void of cells but has structural and functional proteins still intact. Once in place, the matrix 'recruits' cells for tissue remodeling without scarring. ... Dolphin Quest attending veterinarian Gregg Levine said that without the procedure, Liko likely would have faced a partial amputation of his dorsal fin because the injury was too severe to heal properly on its own." We humans can look forward to recieving the benefits of this sort of technology for the regeneration of severely damaged tissue in the years ahead - once the regulatory hurdles are passed.
