Figure 8. Overexpression of BMP3 by adenovirus in vivo alleviated arthritis severity in AIA rats. (A) In vivo imaging of normal and AIA rats. (B) Overexpression of BMP3 in AIA rat synovial tissues injected with ad-BMP3 was analyzed using immunofluorescence staining (original magnification, ×20). (C) BMP3 expression in AIA rat synovial tissues injected with ad-BMP3 was analyzed using IHC staining (original magnification, ×20).
