It's been known for some time that breastmilk contains stem cells, but new research suggests that there are three types of stem cells present in breastmilk, and hints at a role they may play in the development of muscle and bone tissue.
The Independent reports:
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.
Dr Cregan said the discovery of immune stem cells was the "most exciting development", adding, "It's quite possible that immune cells in breast milk can survive digestion and end up in the infant's circulation. This has been shown to be occurring in animals, and so it would be unsurprising if this was also occurring in human infants.
