Patients have been advised not to rush into a new cosmetic surgery procedure for breast augmentation.
The surgery, known as cell enriched breast enhancement, involves transplanting cells and fat from another area of the patient's body into their chests, in order to increase bust size.
But Dr Ravi Jain, a cosmetic expert, has advised patients to wait for more data to become available before they rush to have the procedure.
He said: "Stem cell-based beauty treatments are certainly going to be big in the future but the treatment is still in its infancy, and in my opinion, has at least another 12 to 18 months of modification ahead of it."
Dr Jain conceded that the procedure is "definitely going to be the future of cosmetic treatments" but said that his advice to patients was to "watch this space".
The treatment could provide a natural alternative to silicone implants which carry a risk of rejection.
Stem cell-based augmentation has the further advantage of being permanent while traditional breast augmentation involves implants which generally last around ten years.
