Human milk contains growth-promoting milk-borne trophic factors like hormones, nucleotides, and polyamines. While beneficial for infant development, their exact effects and safe enrichment in infant formulas remain uncertain.

Area of Science:

  • Biochemistry
  • Developmental Biology
  • Pediatrics

Context:

  • Human milk contains bioactive substances beyond major nutrients, termed milk-borne trophic factors.
  • These factors include hormones, peptides, nucleotides, and polyamines (spermine, spermidine).
  • Their concentrations and composition vary during lactation.

Purpose:

  • To explore the classification and biological roles of milk-borne trophic factors.
  • To investigate their potential impact on newborn growth, organ development, and gut health.
  • To assess the feasibility and challenges of enriching infant formulas with these factors.

Summary:

  • Hormones (e.g., IGF-I, EGF) and peptides promote newborn metabolism, organ growth, and may protect against necrotizing enterocolitis.

  • Nucleotides support liver function, lipid metabolism, and gut-associated lymphoid tissue development.
  • Polyamines, abundant in milk, show potential for gastrointestinal tract growth and differentiation, though human data is limited.

    • Impact:

    • Milk-borne trophic factors play crucial roles in infant development and gut health.
    • Enriching infant formulas presents challenges due to unknown long-term effects and complex interactions.
    • Further research is needed to understand the precise benefits and risks before formula modification.
