Cellular reprogramming allows scientists to model age‐related diseases, understand aging mechanisms and prevent aging.

The discovery of fetal scarless skin wound healing is an important breakthrough whose investigation drives many aspects of regenerative medicine and stem cell research. Several features of fetal scarless wound healing are well studied, but the exact mechanism to recapitulate scarless wound healing in adult skin remains elusive (Reprinted with permission from Leavitt et al. (2016). Copyright 2016 Springer).

Schema of skin during embryonic development and in adult (left). After wounding, the adult skin heals by forming a scar which lacks hair follicles, glands, and other structures of the skin with the exception of scar‐free healing in the African spiny mouse (right).

Inhibitory interneurons in the cerebral cortex constitute ~20–30% of the neuronal population. The rich array of interneuron subtypes endows local circuits with a remarkable computational power. How do the developmental origins (i.e. time and place of birth, progenitor behavior, lineage, etc.) influence the production and diversification of cortical interneurons?
