Milk by mail: scientists try to preserve RNA in breastmilk samples

NCT ID NCT07118852

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether adding special preservatives to human milk can keep the RNA intact during shipping. Fifty breastfeeding women in Wisconsin provided samples mixed with one of two preservatives. The goal was to develop a reliable method for remote collection, so researchers can study gene expression in milk without requiring in-person visits.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

RNA preservation reagents (RNAlater and NucleoProtect RNA)

What this could lead to

If successful, this could enable researchers to study gene expression in human milk from participants anywhere, not just in a lab.

What could go wrong

This is a small, early-stage study focused on developing a method, not testing a treatment. The approach may not work for all samples or be practical for widespread use.
