Human Umbilical Cord Mesenchymal Stem Cells Alleviate Rat Knee Osteoarthritisvia Activating Wnt/ β-catenin Signaling Pathway

Overall, this study demonstrated that hUC-MSCs induce the secretion of some cytokines via the paracrine function to activate the Wnt/β-catenin signaling pathway to reduce the pathological condition of OA and maintain the proper expression of cytokines and extracellular matrix proteins.
