Higher Chondrogenic Potential of Extracellular Vesicles Derived from Mesenchymal Stem Cells Compared to Chondrocytes-EVs In Vitro

<div>Immunohistochemical analysis of chondrogenic proteins. (a) IHC staining of type II collagen (Col II) and aggrecan (ACAN). (b) Histograms show the intensity of Col II and ACAN proteins expressed in mesenchymal stem cells (MSCs) that differentiated into chondrocytes in the presence of extracellular vesicles (EVs) derived from chondrocytes (Cho-EV) and MSCs (MSC-EVs) after 21 days. <span class="nowrap"><svg height="13.532pt" id="M38" style="vertical-align:-3.4295pt" version="1.1" viewbox="-0.0498162 -10.1025 50.6052
