Grow-your-own breast implants

Cosmetic surgeons may one day use tissue grown from patients' own stem cells for breast augmentation, following successful research in mice

INSTEAD of silicone implants or tissue taken from elsewhere in the patient鈥檚 body, plastic surgeons might soon be using tissue grown from patients鈥 own stem cells.

So claims Jeremy Mao of the University of Illinois, who has tested the idea in mice. He seeded scaffolds with human bone-marrow-derived stem cells and inserted them into mice.

Four weeks later the implants still retained their size and shape. When tissue from a patient鈥檚 body is used for reconstruction, the implants often deform after just a week, and can halve in volume over later years. 鈥淚t seems promising and could soon be making an impact,鈥 Mao told the American Association for the Advancement of Science conference in Washington DC last week.
