<p>(A) Western blot analysis of active and total β-catenin in stage b1, b2 and b3 lungs, and stage 24 limb (as positive control). Control loading was performed using β-tubulin (55 kDa). Total and active β-catenin correspond to 92 kDa. (B) Semi-quantitative analysis for active and total β-catenin. Results are presented as arbitrary units normalized for β-tubulin. p<0.05: * <i>vs</i> limb.</p
