Going out on a limb


This issue contains a series of papers emphasizing the importance of the limb as a model system in developmental biology. Most of these limb papers were presented at the 8th International Conference on Limb Development and Regeneration, held on the 16th–18th of July in Dundee. A summary of that exciting conference appears in this issue as a ShopTalk entitled, “Digital Dialogues in Dundee: 8th International Conference on Limb Development.” It is our pleasure to publish this special focus on the limb; I hope that you will enjoy reading this cluster of interesting papers.
