Autotherapies: Enhancing Endogenous Healing and Regeneration

The promise of tissue engineering and regenerative medicine to reduce the burden of disease and improve quality of life are widely acknowledged. Traditional tissue engineering and regenerative medicine approaches rely on generation of tissue constructs in vitro for subsequent transplantation or injection of exogenously manipulated cells into a host. While promising, few such therapies have succeeded in clinical practice. Here, we propose that recent advances in stem cell and developmental biology, immunology, bioengineering, and material sciences, position us to develop a new generation of in vivo regenerative medicine therapies, which we term autotherapies. Autotherapies are strategies based on optimizing endogenous tissue responses and capitalizing on manipulation of stem cell niches and endogenous tissue microenvironments to enhance tissue healing and regeneration.
