Volume, Not Firmness or Uplift

A trial underway in Britain is using a stem cell-based therapy to repair the breasts of women following tumor-removal surgery, and a separate trial is using the technique on healthy women, reports the Times Online. The stem cells are extracted from the fat of the woman's stomach or thighs. Surgeons say that the addition of stem cells may promote the growth of blood vessels. Plastic surgeon Eva Weiler-Mithoff says the results from British cancer patients have been promising but notes that that does not justify the cosmetic application of the treatment. The Times also points out: "Although the stem cell technique will restore volume, it will not provide firmness and uplift."
