Cross\u2010fostering improves postnatal nutrition and restores these deficits. Mothers with growth\u2010restricted pups have compromised milk production and composition; however, the impact cross\u2010fostering has on milk production and composition is unknown. Plasma leptin concentrations peak during the completion of organogenesis, which occurs postnatally in rats. Leptin is transferred to the fetus via the placenta and to the pup via the lactating mammary gland. This study investigated the effect of uteroplacental insufficiency on pup plasma leptin concentrations and placental leptin transporters. We additionally examined whether cross\u2010fostering improves mammary development, milk composition and pup plasma leptin concentrations. Fetal growth restriction was induced by bilateral uterine vessel ligation surgery on gestation day 18 in Wistar Kyoto rats (termed uteroplacental insufficiency surgery mothers). Growth\u2010restricted (Restricted) fetuses had reduced plasma leptin concentrations, persisting throughout lactation, and sex\u2010specific alterations in placental leptin transporters. Mothers suckled by Restricted pups had impaired mammary development, altered milk fatty acid composition and increased plasma leptin concentrations, despite no changes in milk leptin. Milk intake was reduced in Restricted pups suckling uteroplacental insufficiency surgery mothers compared to Restricted pups suckling sham\u2010operated mothers. Cross\u2010fostering Restricted pups onto a sham\u2010operated mother improved postnatal growth and restored plasma leptin concentrations compared to Restricted pups suckling uteroplacental insufficiency surgery mothers. Uteroplacental insufficiency alters leptin homeostasis. This is ameliorated with cross\u2010fostering and enhanced milk fatty acid composition and consumption, which may protect the pups from developing adverse health conditions in adulthood.<\/jats:p><\/jats:sec>","DOI":"10.1113\/jp273825","type":"journal-article","created":{"date-parts":[[2017,3,29]],"date-time":"2017-03-29T08:16:52Z","timestamp":1490775412000},"page":"3389-3407","source":"Crossref","is-referenced-by-count":24,"title":["Uteroplacental
