| Open AccessSingle-cell analysis reveals fibroblast heterogeneity and myeloid-derived adipocyte progenitors in murine skin wounds
The diversity of fibroblasts contributing to wound healing is unclear. Here, the authors use single-cell RNA-sequencing to identify heterogeneity among murine fibroblasts in the wound and find that recruited myeloid cells contribute to adipocyte regeneration during healing.

| Open AccessExposure to a youthful circulation rejuvenates bone repair through modulation of β-catenin
The reparative capacity of tissues decreases with age. Here, Baht et al. perform parabiosis experiments and provide evidence for the existence of a soluble factor produced by young, but not old, haematopoietic cells that is capable of improving fracture repair in old mice.
