Story summary

Researchers at Universidad de los Andes have made a groundbreaking discovery: umbilical cord-derived extracellular vesicles (EVs) can transform macrophages into an anti-inflammatory state, significantly slowing cartilage degradation in knee osteoarthritis. This promising finding hints at lasting clinical benefits and safety. In parallel, Pacira BioSciences is pushing forward with gene therapy PCRX-201, now in Phase II trials, targeting long-term relief for osteoarthritis sufferers.
