Figure 8.

Effects of HBP on cartilage recovery determined via immunohistochemical analysis of IL6 expression and chondrogenic potential via Safranin-O staining. (A) Safranin-O-stained cartilage of RA mice. (B) IL6 protein in cartilage of RA mice was stained with avidin-biotin. (C) Quantification of the degree of Safranin-O and (D) IL6 staining of cartilage using Image J software, presented as bar graphs (n = 10 per group). Different alphabets (a, b, c, and d) in each Figure indicate significant differences among experimental groups (p  <  0.05).
