title: Redefining the role of retinoic acid in limb development.
abstract: In recent years, the function of retinoic acid (RA) in limb development has been debated. In this issue of Cell Reports, Cunningham et al. show that RA antagonizes fibroblast growth factors for limb initiation, but not for limb patterning.
