Gene therapy is a novel treatment method which utilizes genes or short oligonucleotide sequences as therapeutic molecules, instead of conventional drug compounds. This technique is widely used to treat those defective genes which contribute to disease development. This book outlines methods available for gene transfer as well as current and potential applications for craniofacial regeneration, with emphasis on future development and design. The process of gene therapy remains complex and many techniques need further developments. The challenge of developing successful gene therapy for any specific condition is considerable. This book will be of beneficial to students and practitioners who would benefit from seeing the phenotypes of the genes they work on and study.
