The technique, pioneered in Japan, results in breasts that look
and feel smoother than conventional cosmetic surgery using implants
. This is because the stem cells enable the fat to grow its own blood supply, thus becoming an integral part of the breast rather than a foreign lump.
Stem cells have the potential to change into any cells in the body. They are found in most tissues, especially fat.
Dozens of women in Japan have received the breast enlargements during trials.
