The use of model organisms together with the power of genetics has profoundly affected our understanding of the physiology of one organ, the skeleton, in two distinct but complementary ways. This is the first translational reference to focus on these major conceptual advances in bone biology and their development in the clinic. Several advances have already been translated into therapies and others are being tested for diseases as different as osteoporosis, type-2 diabetes, and hypo-fertility. This book is a timely reference for both basic and clinical researchers in bone biology and endocrinology.
