• Resumen

  • Mechanisms underlying aging of the skin dermis are poorly understood. Now, two studies (Marsh et al., 2018 , Salzer et al., 2018 ) describe complementary approaches to this question: Salzer et al. show that aging dermal fibroblasts lose defined identity in a diet-influenced fashion, and Marsh et al. reveal that fibroblast loss over time is compensated by membrane expansion rather than proliferation, resulting in decreased cellular density.
