Chondrogenic differentiation of MSC embedded in pure PEC particles at 21 days. (A) Collagen type II detected by ELISA assay. Collagen type II was detected in both the 1:2 and 1:1 formulations. Medium supplementation did not make a significant different in Collagen type II production in the 1:2 and 2:1 formulations. * for p<=0.05 compared to 1:2 with either treatment. (B) Total collagen content visualized via Van Gieson’s Acid Fuchsin (arrows). The extent of Acid Fuchsin staining qualitatively corresponded to the results of the Collagen type II ELISA. Brown regions are PEC. Scale bar = 200 μm.
