We’ve long known that human milk is more than calories. It’s communication. I speak about this often because the science keeps growing, and it’s extraordinary.
A new review in Nature (Majood and Rao, 2025) shows just how alive and dynamic human milk truly is.
Human milk carries living cells, including stem-like cells that may support infant immune and tissue development.
It holds tiny signaling vesicles that help guide gene expression, metabolism, and immunity.
And scientists are now using milk-derived cells to create mammary organoids. These models help us study lactation, breast health, and even explore regenerative medicine.
Human milk may one day help us repair organs, understand disease, and rethink mammary function. All while nourishing babies in ways formula simply cannot replicate.
When we support lactation, we aren’t just feeding babies.
We’re honoring one of the most sophisticated biological systems in the human body.
If your group, hospital, or organization would like an evidence-based talk on the science of human milk, reach out. I’d love to teach and support your team.
