The sex and reproductive plasticity of intestinal muscles instruct gut size

Alessandro Mineo, Laura Blackie, Alexandra Milona, Emily Strachan et autres

Adult organs enlarge or regress in response to functional demands: changes commonly attributed to the dynamics of their resident stem cells. A striking example is the intestine, whose length varies with diet and reproductive status. We find that the size of the …

Growth of the maternal intestine during reproduction

Tomotsune Ameku, Anna Laddach, Hannah Beckwith, Alexandra Milona et autres

The organs of many female animals are remodeled by reproduction. Using the mouse intestine, a striking and tractable model of organ resizing, we find that reproductive remodeling is anticipatory and distinct from diet- or microbiota-induced resizing. Reproductive remodeling involves partially irreversible elongation …
