By mistake, Figure 2 of the article by Haddad-Tóvolli et al. (2015) showed in panels (A) and (B) the same image of Gli1 expression in E8.5 wildtype mouse embryos. It should have shown Gli1 expression in (A) and Gli2 expression in (B). Therefore, we provide a corrected Figure 2, now with panel (B) showing Gli2 expression, as we originally intended and as the Figure legend indicates. This is a minor change not affecting the scientific content of the article.
