Bone regeneration is a fascinating process in which, after injury, bone is able to regain full functionality without scar formation. Although the process is successful in most cases, there are conditions in which the bone fails to heal leading to delayed or nonunions (e.g., large segmental defects due to trauma or cancer).

If the process becomes uncoupled and the rate of resorption exceeds the rate of formation, the resulting bone loss can lead to osteoporosis and, consequently, a higher susceptibility to fractures. Osteoporosis is a metabolic bone disease characterized by low bone mass and abnormal bone microarchitecture.
The process of bone remodeling is initiated with the osteoclastic resorption of an old bone, and osteoblasts subsequently migrate into the resorption lacuna, leading to …
