Mommy’s Milk Human Milk Biorepository at UC San Diego is building a research database that will be used to evaluate human milk. As the first-ever human milk research biorepository in the nation, we are moving science forward through highly-trained researchers contributing to human milk breakthroughs and discoveries.

Our goal is to understand all aspects of human milk in hope that this will lead to optimal health for mothers and infants. Clinical data points will be collected from all human milk donors including health outcomes of infants. Contact us to learn how you can get involved and request human milk samples.

Variables collected include:

  • Maternal Age
  • Race
  • Ethnicity
  • Education
  • Income
  • Primary Language
  • Height
  • Weight
  • Pregnancy History (Gravidity, Parity, SAB,TAB)
  • Breastfeeding History (Breastfeeding History and Duration)
  • Child Eating Habits (EBF, Formula, Solids)
  • Personal Medical History
  • Family Medical History
  • Child Age
  • Child Birth Weight, Length and Head Circumference
  • Child Apgar Scores
  • Preterm Birth
  • Delivery Mode
  • Child Current Weight, Length and Head Circumference (at the time of the milk sample)
  • Pediatric abnormalities
  • Maternal exposures (dose, frequency, dates for 7 days prior to collection)
  • Adverse Reactions
  • Maternal sleep habits
  • Maternal exercise habits
  • Milk sample collection conditions
  • EPDS score
  • STAI score
  • PSS-10 score
  • Food Frequency Questionnaire
  • ASQ
  • CDI

Sample Processing and Storage: Upon receipt, milk samples are aliquoted and transferred to the Altman Clinical and Translation Research Institute (ACTRI) Biorepository, where they are stored in -80 degree conditions. The ACTRI Biorepository was supported by the National Institutes of Health, Grant UL1TR000100 of CTSA funding prior to August 13, 2015 and is currently supported by Grant UL1TR001442 of CTSA funding beginning August 13, 2015 and beyond.

Current Research Analyses:

Mommy’s Milk Human Milk Biorepository supports and conducts human milk research throughout the nation and abroad. Research projects currently utilizing human milk donations from our biorepository are paving the way for the future growth of our program.  Current research projects include:

Coronavirus (COVID-19)
We are studying breast milk from women who have exposure to the novel coronavirus (COVID-19). Much is unknown about COVID-19 and whether the virus and the medications used to treat it can be transmitted from mother to baby via breast milk. Please consider joining our study to help us better understand COVID-19 and its treatment during breastfeeding. Participation involves providing a breast milk, nasal, saliva, blood and stool sample from mom, and nasal, blood and stool sample from child. Not all samples are required.

COVID-19 Vaccine

We’re studying breast milk from people who have received the COVID-19 vaccine. Little is known about the use of this new vaccine by breastfeeding moms and whether the immunity that a mom develops is passed to her baby in breast milk. Please consider joining this study to help us gather this critical information. Participation involves providing up to 7 milk samples in the 45 days after receiving the vaccine, phone interviews, release of medical records for both mom and baby, and mailed or online questionnaires about baby’s development.

Cannabinoids in Human Milk
We are measuring the quantity of cannabinoids (∆9-THC, 11-OH-THC, CBD, and CBN) in human milk samples provided by breastfeeding mothers who report recent marijuana use.
