Safranin-O staining of C-ABC treated specimens to examine the distribution of sulfated GAGs. Some positive staining (red color) can be found in TMJ disc samples immediately surrounding cells, but very low overall staining was observed, and no staining was detected in the matrix. In contrast, intense positive staining can be seen throughout the matrix of articular cartilage. C-ABC treatment produced a small but visible difference in some TMJ disc samples. Treatment of hyaline cartage produced a very obvious depletion of GAGs starting at the edge of the tissue and proceeding toward the center. (Scale bar = 100 μm)
