Fig. 9From: PLGA nanoparticles engineering extracellular vesicles from human umbilical cord mesenchymal stem cells ameliorates polyethylene particles induced periprosthetic osteolysisSchematic diagram of PLGA-Exos alleviates PE particles-induced mouse calvarial osteolysis. (A) Construction of PLGA-Exos. (B) Local injection of PLGA-Exos at osteolytic sites. (C) PLGA-Exos continuously released exosomes, enhanced osteogenic differentiation, and inhibited osteoclast formation. (By Figdraw)Back to article page
