Procr+ chondroprogenitors sense mechanical stimuli to govern articular cartilage maintenance and regeneration.
Cell·September 18, 2025·PMID 40695281
Why it mattersThis paper identifies a specific stem cell population and a mechanosensitive pathway (Piezo1) that are critical for cartilage maintenance and repair. For pain specialists, understanding these regenerative mechanisms may inform future biologic or mechanotherapy strategies to address the underlying structural damage in osteoarthritis, which is a major driver of chronic knee pain.
