Revivicor Inc. is a regenerative medicine company focused on applying leading-edge animal biotechnology platforms to provide a superior quality, high-volume, human-compatible, alternative tissue source for treatment of human degenerative disease. The Virginia-based company was formed in 2003 as a spin-out from the UK company PPL Therapeutics, which produced the first cloned animal: Dolly the Sheep. Revivicor has subsequently built on this technology, cloning the first genetically-engineered (GE) pigs, and now produces pig islets, organs, and medical devices aimed at human clinical applications.
