The adult human skeleton undergoes constant remodeling, with new bone forming at sites that have been broken down by a precise process called resorption. During remodeling, skeletal stem cells are recruited to resorption sites and directed to differentiate into bone-forming cells. Osteoporosis, a condition characterized by weak and fragile bones, develops when there is an imbalance in the remodeling process and more bone is lost than replaced. Now, new research published by Cell Press in the November issue of the journal Cell Stem Cell uncovers a mechanism that may guide development of better strategies for treatment osteoporosis.
