Fan Y, Chong YS, Choolani MA, Cregan MD, Chan JK.
PLoS One. 2010 Dec 28;5(12):e14421.

Abstract

BACKGROUND: Mammary stem cells have been extensively studied as a system to delineate the pathogenesis and treatment of breast cancer. However, research on mammary stem cells requires tissue biopsies which limit the quantity of samples available. We have previously identified putative mammary stem cells in human breast milk, and here, we further characterised the cellular component of human breast milk.

Serum lutein concentrations in healthy term infants fed human milk or infant formula with lutein.

Bettler J, Zimmer JP, Neuringer M, DeRusso PA.
Eur J Nutr. 2010 Feb;49(1):45-51.

Abstract

Background Lutein is a carotenoid that may play a role in eye health. Human milk typically contains higher concentrations of lutein than infant formula. Preliminary data suggest there are differences in serum lutein concentrations between breastfed and formula-fed infants.

Aim of the study To measure the serum lutein concentrations among infants fed human milk or formulas with and without added lutein.

Characteristics and potential functions of human milk adiponectin

Newburg DS, Woo JG, Morrow AL.
J Pediatr. 2010 Feb;156(2 Suppl):S41-6.

Abstract

Adiponectin is a protein hormone produced by adipose tissue, whose circulating levels are inversely related to adiposity and inflammation. Adiponectin circulates as oligomers, from the low-molecular-weight trimer to the high-molecular-weight octodecamer (18 mer). Each oligomer has distinct biological activities, which include enhancement of insulin sensitivity and metabolic control and suppression of inflammation. Adiponectin occurs in human milk at higher concentrations than leptin.

Abstract

Objective Domperidone is increasingly prescribed to improve breast milk volume despite a lack of evidence regarding its effects on breast milk composition. We examined the effect of domperidone on the nutrient composition of breast milk.

Protection of the Neonate by the Innate Immune System of Developing Gut and of Human Milk

Newburg, DS.; Walker, WA.
Pediatr Res 61: 2–8, 2007

Abstract

The neonatal adaptive immune system, relatively naïve to foreign antigens, requires synergy with the innate immune system to protect the intestine. Goblet cells provide mucins, Paneth cells produce antimicrobial peptides, and dendritic cells (DCs) present luminal antigens. Intracellular signaling by Toll-like receptors (TLRs) elicits chemokines and cytokines that modulate inflammation. Enteric neurons and lymphocytes provide paracrine and endocrine signaling. However, full protection requires human milk. Breast-feeding reduces enteric infection and may reduce chronic disease in later life. Although human milk contains significant secretory immunoglobulin A (sIgA), most of its protective factors are constitutively expressed. Multifunctional milk components are nutrients whose partial digestion products inhibit pathogens. Cytokines, cytokine receptors, TLR agonists and antagonists, hormones, anti-inflammatory agents, and nucleotides in milk modulate inflammation.

Retention of the Immunological Proteins of Pasteurized Human Milk in Relation to Pasteurizer Design and Practice

Czank C, Prime DK, Hartmann B, Simmer K, Hartmann PE.
Pediatr Res. 2009 Oct;66(4):374-9.

Abstract

Pasteurizing donor human milk inactivates bacteria that may be of concern to the preterm infant. However, current practice for Holder Pasteurization (62.5 degrees C for 30 min) is detrimental to the bioactivity of human milk.

Serum lutein concentrations in healthy term infants fed human milk or infant formula with lutein

Eur J Nutr. 2009 Aug 12.

Abstract

Background Lutein is a carotenoid that may play a role in eye health. Human milk typically contains higher concentrations of lutein than infant formula. Preliminary data suggest there are differences in serum lutein concentrations between breastfed and formula-fed infants.
Aim of the study To measure the serum lutein concentrations among infants fed human milk or formulas with and without added lutein.

Human milk adiponectin is associated with infant growth in two independent cohorts

Woo JG, Guerrero ML, Altaye M, Ruiz-Palacios GM, Martin LJ, Dubert-Ferrandon A, Newburg DS, Morrow AL.
Breastfeed Med. 2009 Jun;4(2):101-9.

Abstract

BACKGROUND: Adiponectin, a circulating adipocyte protein, is associated with lower obesity. We have previously shown that adiponectin is present in human milk. This study determined whether higher milk adiponectin is associated with infant growth and investigated milk adiponectin's oligomeric form.

Breastfeeding—An Extrauterine Link Between Mother and Child

Samuli Rautava and W. Allan Walker
BREASTFEEDING MEDICINE Volume 4, Number 1, 2009

Abstract

In addition to a near-optimal combination of nutrients for the growing infant, breastmilk contains a wide array of bioactive molecules that are known to protect the infant against infectious disease and modulate the composition of the indigenous intestinal microbiota. A growing number of factors that modulate the infant’s immunophysiology have also been identified in breastmilk.

Effects of Different CMV-Heat-Inactivation-Methods on Growth Factors in Human Breast Milk

Rangmar Goelz, Eva Hihn, Klaus Hamprecht, Klaus Dietz, Gerhard Jahn, Christian Poets,
and Martin Elmlinger
Pediatr Res 65: 458–461, 2009

Preterm infants can inoculate virulent cytomegalovirus (CMV) through their mothers’ raw breast milk. Complete virus inactivation is achieved only by heat treatment, but the effect on growth factors has never been assessed systematically.

Pancreatic secretory trypsin inhibitor is a major motogenic and protective factor in human breast milk

Tania Marchbank, Gillian Weaver, Marit Nilsen-Hamilton and Raymond J. Playford

Am J Physiol Gastrointest Liver Physiol 296: G697-G703, 2009.

Colostrum is the first milk produced after birth and is rich in immunoglobulins and bioactive molecules. We examined whether human colostrum and milk contained pancreatic secretory trypsin inhibitor (PSTI), a peptide of potential relevance for mucosal defense and, using in vitro and in vivo models, determined whether its presence influenced gut integrity and repair.

The possible role of human milk nucleotides as sleep inducers

Sánchez CL, Cubero J, Sánchez J, Chanclón B, Rivero M, Rodríguez AB, Barriga C.
Nutr Neurosci. 2009 Feb;12(1):2-8.

Abstract

Breast-milk contains a potent mixture of diverse components, such as the non-protein nitrogen fraction which includes nucleotides, whose variation in levels is evident throughout lactation. In addition, these substances play an important role in sleep homeostasis. In the present study, human milk samples were analyzed using a capillary electrophoresis system. The rhythmicity of each nucleotide was studied by cosinor analysis.

Oropharyngeal administration of colostrum to extremely low birth weight infants: theoretical perspectives

N A Rodriguez, P P Meier, M W Groer and J M Zeller

Journal of Perinatology (2009) 29, 1–7

Own mother's colostrum (OMC) is rich in cytokines and other immune agents that provide bacteriostatic, bacteriocidal, antiviral, anti-inflammatory and immunomodulatory protection against infection. OMC may be especially protective for the extremely low birth weight (ELBW) infant in the first days of life; however clinical instability typically precludes enteral feedings during this period.

Differential transfer of dietary flavour compounds into human breast

Hausner H, Bredie WL, Mølgaard C, Petersen MA, Møller P.

Physiol Behav. 2008 May 15.

Abstract

Transfer of dietary flavour compounds into human milk is believed to constitute the infant's early flavour experiences. This study reports on the time-dependent transfer of flavour compounds from the mother's diet to her breast milk using a within-subject design.
