Scrapie-Responsive Gene 1 Promotes Chondrogenic Differentiation of Umbilical Cord Mesenchymal Stem Cells via Wnt5a

<div>SCRG1 regulated chondrogenesis of UCMSCs through Wnt5a signaling pathway. (a) Regulating pluripotency of stem cell signaling pathway was the most significantly enriched KEGG pathway based on GSEA, wnt5a was negatively correlated with this pathway after SCRG1 overexpression. (b, c) Western blot analysis showed that Wnt5a decreased after shSCRG1 transfection and was restored after administration of rhSCRG1 (450 ng/mL); protein levels of <i>β</i>-catenin exhibited the opposite trend to Wnt5a. (d, e) Protein levels of COL2A1 and ACAN were detected in UCMSCs by IHC. The results showed that the protein levels of COL2A1 and ACAN were reduced following SCRG1 knockdown and restored after treated with rhWnt5a (300 ng/mL) and rhSCRG1 (450 ng/mL) protein at 24 h. <span
