Fig. 5From: T1ρ magnetic resonance imaging quantification of early articular cartilage degeneration in a rabbit modelShown were sections of Safranin-O and Fast Green stained (×100) FCC from Group e, and the experimental sides of Group a-d. In Group a-d, intensity of red positively correlated with the presence of glycosaminoglycans attached to PG gradually became pale, meanwhile the range of Fast Green staining of the collagen fibers gradually increased, indicating early cartilage degenerationBack to article page
