Figure 1From: BMP-2 functions independently of SHH signaling and triggers cell condensation and apoptosis in regenerating axolotl limbsExpression patterns (whole mount in situ hybridisation) for BMP-2, SOX-9 and Shh in developing limbs and cartilage staining (Victoria blue V.b.). All pictures show a dorsal view of the limb with the posterior side on top. Numbers in the upper left of each panel refers to the developmental stages [51].Back to article page
