Effect of breast milk and weaning on epithelial growth of the small intestine in humans

Breast feeding and weaning are important physiologically significant luminal events that influence the growth of the small intestine in humans. A variety of factors including genetic preprogramming, systemic and local hormones, and permissive factors contribute and modulate intestinal growth. Here, we offer a view that integrates some of these factors, especially those relating to breast feeding and weaning.
