    Homeostasis, injury, and recovery dynamics at multiple scales in a self-organizing mouse intestinal crypt

    Louis Gall, Carrie Duckworth ... Carmen Pin
    Novel modelling strategies can integrate the dynamics of processes regulating the intestinal epithelium at multiple scales in homeostasis and following perturbations to provide unprecedented insights into the biology of the epithelium and support the development of safer novel drug candidates.

    Embryonic origin of adult stem cells required for tissue homeostasis and regeneration

    Erin L Davies, Kai Lei ... Alejandro Sánchez Alvarado
    Anarchic, cycling piwi-1+ embryonic cells gives rise to neoblasts, pluripotent stemcells required for development of all organ systems during S. mediterranea embryogenesis, as well as the maintenance andregeneration of tissues during adulthood.

    Female-biased upregulation of insulin pathway activity mediates the sex difference in Drosophila body size plasticity

    Jason W Millington, George P Brownrigg ... Elizabeth J Rideout
    The ability to adjust body size in response to diet is greater in Drosophila females than males because of a sex difference in the nutrient-dependent regulation of the insulin pathway.
