Scientist says mother's milk may play vital role in helping children 'fulfil their genetic destiny'

Breast milk, long revered for the nutritional advantages it gives a newborn, could be just as vital in terms of infant development, a leading scientist will claim this week. Up to three different types of stem cells have been discovered in breast milk, according to revolutionary new research.
Dr Mark Cregan, medical director at the Swiss healthcare and baby equipment company Medela, believes the existence of stem cells means breast milk could help a child "fulfil its genetic destiny", with a mother's mammary glands taking over from her placenta to guide infant development once her child is born.
"Breast milk is the only adult tissue where more than one type of stem cell has been discovered. That is very unique and implies a lot about the impressive bioactivity of breast milk and the consequential benefits to the breastfed infant," said Dr Cregan, who is speaking at Unicef's Baby Friendly Initiative conference this week. His research has isolated adult stem cells of epithelial (mammary) and immune origin, with "very preliminary evidence" that breast milk also contains stem cells that promotes the growth of muscle and bone tissue.
Scientists will use his discovery, made at the University of Western Australia, in Perth, Australia, to attempt to harvest stem cells from breast milk for research on a range of issues – from why some mothers struggle to produce milk to testing out new drugs that could aid milk production. "There is a plentiful resource of tissue-specific stem cells in breast milk, which are readily available and from a non-invasive and completely ethical source," Dr Cregan said.
