The underlying mechanism for radiation induced muscular atrophy, obtained as a result of radiotherapy for children, has been insufficiently studied. The ultimate goal of the study was to investigate therapeutic doses of x-irradiation on human skeletal muscle stem cells, primary myoblasts, which are responsible for the development of adult muscle fiber and muscular maintenance and regeneration. This book "Influence of Therapeutic Doses of Ionizing Radiation on Human Muscle Stem Cells" will appeal a wide variety of readers. It will be of interest to technologists in radiation therapy, nuclear medicine, cancer research students, medical physicist, and trainee radiotherapist.
