Here, Pagani et al. use the Hoxa11 patterning gene, expressed exclusively in the limb zeugopod, to demonstrate by bioinformatic single cell transcriptomic, epigenomic analyses, and ex vivo confocal microscopy that extra-skeletal cells originating from Hoxa11 lineage cells are a population of mesenchymal cells with the ability to undergo aberrant differentiation towards chondrocytes, osteoblasts or adipocytes after injury
