Vienna doctor claims natural breast augmentation is possible with stem cells. "Typically an enlargement of the breast by one or two cup sizes can be obtained. The implanted volume of stem cell concentrated own-fat will be almost completely preserved."  

I'm not a believer in other claims of natural breast augmentation like breast enhancement gum, so I'll have to check with some plastic surgeons whether they believe this is possible. 

In the meantime, Dr. Karl-Georg Heinrich claims natural augmentation via stem cells will work on the hips, bottom, thighs, calves, as well as to "rejuvenate lined hands."
