Breast milk as stem cells!

Breast milk contains stem cells*(ScienceAlert)

The Perth scientist who made the world-first discovery that human breast milk contains stem cells is confident that within five years scientists will be harvesting them to research treatment for conditions as far-reaching as spinal injuries, diabetes and Parkinson’s disease.

But what Dr Mark Cregan is excited about right now is the promise that his discovery could be the start of many more exciting revelations about the potency of breast milk.

He believes that it not only meets all the nutritional needs of a growing infant but contains key markers that guide his or her development into adulthood.

“We already know how breast milk provides for the baby’s nutritional needs, but we are only just beginning to understand that it probably performs many other functions,” says Dr Cregan, a molecular biologist at The University of Western Australia.

He says that, in essence, a new mother’s mammary glands take over from the placenta to provide the development guidance to ensure a baby’s genetic destiny is fulfilled.

“It is setting the baby up for the perfect development,” he says. “We already know that babies who are breast fed have an IQ advantage and that there’s a raft of other health benefits. Researchers also believe that the protective effects of being breast fed continue well into adult life.

“The point is that many mothers see milks as identical – formula milk and breast milk look the same so they must be the same. But we know now that they are quite different and a lot of the effects of breast milk versus formula don’t become apparent for decades. Formula companies have focussed on matching breast milk’s nutritional qualities but formula can never provide the developmental guidance.”

It was Dr Cregan’s interest in infant health that led him to investigate the complex cellular components of human milk. “I was looking at this vast complexity of cells and I thought, ‘No one knows anything about them’.”
