Human Milk Research — Yimin Chen

The Human Milk Research laboratory works to improve the health and wellness of preterm infants and their lactating mothers. Our work focuses on discovering the impact of maternal mental health on human milk components and the subsequent influence on infant disease risk. We take a comprehensive approach, utilizing cellular and molecular models, neonatal piglet model and human preterm infant intervention trials.

Research

  • Intestinal epithelial cells (Caco2BBe) to explore anti-inflammatory and anti-cytotoxic effects of human milk digestion-resistant proteins and digestion-released peptides
  • Bacterial cultures to explore anti-microbial activities of human milk digestion-released peptides
  • Enteroids to determine specific anti-inflammatory and anti-cytotoxic mechanisms of human milk digestion-resistant proteins and digestion-released peptides with the use of transcriptomics, qPCR and Western blot
  • Enteroids to determine effects of human milk digestion-resistant proteins and digestion-released peptides on tight junction proteins

The Piglet Intervention Center (PInC) is a facility here on the U of I campus dedicated to using neonatal piglets as a model to study impacts of nutrition interventions on the gastrointestinal (GI) tract, microbiome, immune system and neurocognitive development of neonatal mammals. There are many correlational studies examining the beneficial effects of human milk, pasteurized donor milk and infant formula on these systems. However, direct mechanistic investigations are often not possible since taking intestinal and brain samples from humans cannot be ethically justified. Similarities in the intestinal physiology, immunity and brain function between humans and pigs make the piglet a superior model among non-primate animal models to study the effects of nutrition interventions on these systems — particularly in early life.

  • Individual rearing cages
  • Novel Objective Recognition arena to assess neurocognitive development
  • Ussing chambers to determine intestinal barrier function and nutrient absorption
  • Combined molecular and 'omics techniques to study specific mechanisms involved in intestinal growth and development, barrier function, immune function/development and neurodevelopment

We have established collaborative relationships with the neonatal intensive care units (NICU) in Oregon Health and Science University and University of Washington Medical Center to study:

  • Maternal stress in mothers of preterm infants and its association with HM proteins/peptides
  • Feasibility study on a modified eight-week mindfulness-based intervention to reduce stress and increase self-compassion in mothers of preterm infants
  • Association between reduced stress and increased self-compassion on HM proteins/peptides in mothers of preterm infants
  • Explore the impact of different human milk immune protein/peptide profiles on the recipient preterm infant utilizing transcriptome and metabolome
