Stem cell therapy involves the transplantation of stem cells for the rebuilding of hematopoietic cells and tissues. Medically, stem cells are used in the treatment of cancers of the blood and bone marrow. The procedure may be autologous, where the patient provides the cells to be transplanted or allogenic, where there is a healthy host and a patient that receives the stem cells. Transplant of stem cells provide a complete cure or long-term remedy to otherwise fatal diseases. Modern medical research has ensured a high success rate of this procedure. This book, with its detailed analyses and data, will prove immensely beneficial to medical professionals and students involved in this area at various levels. Different approaches, evaluations, methodologies and advanced studies on stem cell therapy have been included in this book.
