This book offers an updated overview of the most recent research advances in the field, a comparison of established techniques and methods, a discussion on current experimental and translational challenges, and a commentary on potential opportunities and future directions.  Dedicated chapters address and review the preclinical and clinical state-of-the-art of gene therapies for the reconstructive and regenerative surgery of skin and wounds, pathological scars, cartilage, tendons, skeletal muscles, and bio-engineered flaps. A brief guide to developing gene therapy clinical trials in the context of reconstructive and regenerative surgery is also provided. Biomedical and technological innovations are transforming our capacity to use gene therapies to safely and effectively repair, reconstruct, and regenerate tissues that are deficient or have been damaged by trauma and diseases.
