A non-invasive therapeutic strategy for improving bone healing in aged patients
Bone repair is a tightly coordinated biological process that relies on stem and progenitor cells to rebuild damaged bone tissue. In younger individuals, these cells rapidly differentiate into osteoblasts—the bone-forming cells that generate new mineralized tissue. With aging, however, this process slows dramatically. Clinicians have long observed that fractures in older adults heal more slowly and are often associated with impaired recovery; however, the molecular signals driving this decline have remained unclear. Understanding why bone regeneration falters with age is critical amid global population aging and rising fracture-related disability.
Against this backdrop, ...
