Fig 5.
Human marrow-derived MSC chondrogenic cultures treated with either SB216763 or Lithium chloride. A. The graph demonstrating that in a chondrogenic culture treated with SB216763 (SB) and Lithium there was significantly more GAG in the ECM. * Indicated a significant difference, p<0.05. Representative sections from the cultures treated with Lithium chloride (B) and SB216763 (C). Apparently, abundant methachromatic matrix was produced in these cultures compared to that in the control untreated culture (D). All sections were stained with toluidine blue (Bar = 500 µm)
