Palla2, Stuart Goodman1, Helen M. Blau2*, Nidhi Bhutani1* Aging or injury to the joints can lead to cartilage degeneration and osteoarthritis (OA), for which there are limited effective treatments. We found that expression of 15-hydroxy prostaglandin dehydrogenase (15-PGDH) is increased in the articular cartilage of aged or injured mice. Both systemic and local inhibition of 15-PGDH with a small-molecule inhibitor (PGDHi) led to regeneration of articular cartilage and reduction in OA-associated pain. Using single-cell RNA-sequencing and multiplexed immunofluorescence imaging of cartilage, we identified the major chondrocyte subpopulations. …
