Flow diagram illustrating placental transfer of maternal iron via the transferrin receptor (TfR) and divalent metal transporter (DMT-1), which ensures substantial iron stores, both in the human and monkey neonate. If born with low ferritin, there is a higher risk for anemia by 4–8 months of age, as growth-related needs exceed bioavailable iron in breast milk.
