Some special human cells that are able to differentiate into many different cell types are called stem cells. They can range from muscle cells to brain cells. Stem cells are divided into two main forms, namely, embryonic stem cells and adult stem cells. The area of research that studies the properties of stem cells and their potential use in medicine is referred to as stem cells research. Advances in stem cell-based therapies may be used to treat serious illnesses such as paralysis and Alzheimer's disease in the future. This book elucidates the concepts and innovative models around prospective developments in relation to stem cells research. Different approaches, evaluations, methodologies, and advanced studies on this topic have been included in this book. It will serve as a reference to a broad spectrum of readers.
