Fibrocartilage formation by the bursa MSCs. (A) H&E staining of the fibrocartilagenous area within the tissue section from the scaffold that was seeded with bursa MSCs not pretreated with BMP-12. (B) Fibrocartilagenous area stained with toluidine blue showed staining of cartilage matrix. (C) Immunofluorescence staining for type II collagen in the fibrocartilagenous tissue confirmed that bursa MSCs form cartilage in vivo. Magnification 100×.
