Procr+ chondroprogenitors sense mechanical stimuli to govern articular cartilage maintenance and regeneration
Zhu et al. identified Procr+ chondroprogenitors in the superficial layer of articular cartilage and meniscus, which are sensitive to mechanical stimulation and regenerate articular chondrocytes in a Piezo1-dependent manner, highlighting their therapeutic potential in treating cartilage defects and osteoarthritis.
