Fig. 6From: Co-culture of hWJMSCs and pACs in double biomimetic ACECM oriented scaffold enhances mechanical properties and accelerates articular cartilage regeneration in a caprine modelhWJMSCs participated in the repair and regeneration of articular cartilage. The results of immunofluorescence (IF) staining for HLA-ABC were used to track hWJMSCs in the ACCC group at 9 months. Green indicates positive immunofluorescence staining for HLA-ABC, and blue shows nuclear staining by Hoechest33258. The repair area (RA) shows positive staining results, while the normal area (NR) was negativeBack to article page
