Bioartificial Organs: Risks and Requirements

The development of therapies based on bioartificial organs requires the appropriate tissue, material, and process selections. While the requirements for tissue engineered products, such as bioartificial skin and cartilage, differ from immunoisolation-based devices such as the bioartificial liver and pancreas, six key issues must be addressed, concomitantly, as one integrated clinical feedback with basic research and product development. These are summarized below.
