MVD in synovial tissues of rats. MVD was determined by CD34 immunohistochemical staining. Black arrows indicate the microvessels, surrounded by CD34-positive cells, which formed a lumen-like structure. Magnification, ×400. Low density of microvessels was observed in the control group (C). High density of microvessels was observed in the model group (M). MVD in the intervention group (I) was decreased compared with that in the model group. MVD, microvascular density; CD34, cluster of differentiation 34.
