Figure Lengend Snippet: Differential gene expression besed on Single-cell RNA sequencing of joint cell clusters following extracellular vesicle (EVs) treatment . ( a-d ) Comparison of gene expression in EVs, PBS, and WT groups (a) in Cluster 6 (chondrocyte progenitors) (COL2A1, COL1A2, PRG4, MMP3, CCL2, and FGF18). ( b ) in Cluster 1 (NK cells) (CD14, MRC1, CD163, CD86, CD80, and NOS2). ( c ) in Cluster 8 (Mesenchymal cells) (COL2A1, COL1A2, PRG4, CCL2, and FGF18) ( d ) in Cluster 4 (Neutrophils) (APOE, AGPAT4, HAPLN1, CDKN1C, MET, and CEMIP2). (e) Flow cytometry analysis confirmed that the proportion of CD11b + CD163 + M2 macrophages was approximately 2.5-fold higher in the EVs-treated group compared to the PBS-treated group.
Article Snippet: For adipocyte differentiation, either BioMirai Lab's induction kit or PromoCell's mesenchymal stem cell adipocyte differentiation medium was used, with Oil Red O staining to assess lipid accumulation.
