They’ve tried this before, because it’s such an obvious idea: liposuction the fat from your belly and inject it into your breasts. The innovation this time is to use only the fat’s stem cells.

Scientists say they are not sure quite how it works, but suspect that the stem cells emit signals that encourage blood vessels to grow and nurture new tissue.

“Not quite sure how it works” is a bit of a red flag, the kind you get from reading about Frankenstein’s monster. But this is still in the experimental phase. The research is to help women who’ve had mastectomies, so you know that eventually the procedure will be available to whoever can pay for it. It also raises another question... since when is it this easy to extract one’s own stem cells? Can we extract stem cells from brain matter and grow some new brains?
