Fig. 5From: Chondrogenic differentiation of bone marrow-derived mesenchymal stem cells following transfection with Indian hedgehog and sonic hedgehog using a rotary cell culture systemALP activity. (a) ALP activity levels from each group in the 2D environment. (b) ALP activity levels from each group in the RCCS environment. Values are means ± SD (n = 3). Significant differences from the control group (non-transfection cells) are indicated by *p < 0.05 or **p < 0.01; differences between IHH and SHH transfection groups are indicated by #p < 0.05 or ##p < 0.01Back to article page
