In a majority of incidents involving damage or injuries, the healing process involves formation of a scar, which is like a patch, reinstating structural integrity of the damaged tissue without reviving physiological functions. A far better option for a patient affected by tissue damage would be to replace the damaged tissue with something functionally similar. Increasing amount of study and research is being undertaken across the world in search for such a technology. This book provides a timely overview on crucial topics in tissue regeneration, in a well-researched manner, written by experts from around the globe. It facilitates a better understanding of normal healing and the methods of applying stem cells. This book will be a great source of reference for study and work undertaken by students, experts and medical professionals.
