For more natural breast augmentations

An American biotech company is working on developing a technique that would allow them to use fatty tissues taken from the abdomen or thighs, to replace the malignant tissues removed from the breasts of women suffering from breast cancer, during mastectomies.

An American biotech company is working on developing a technique that would allow them to use fatty tissues taken from the abdomen or thighs, to replace the malignant tissues removed from the breasts of women suffering from breast cancer, during mastectomies.

This new technique would increase the survival rate of lipid (fatty) cells, which tend to expire or be re-absorbed by the body once they have been transplanted. These cells also tend to calcify when relocated in the breast, making breast cancer detection very difficult.

The researchers at Cytori Therapeutics discovered that it was possible to extract stems cells from fatty tissues. These stem cells were then remixed with normal lipid cells. The researchers believe that adding stem cells to fatty tissues increases their chances of survival not only when they are transplanted in the breast, but also elsewhere in the body.

Plastic surgeons already use fat injections for a variety of minor interventions, such as filling in wrinkles for example. Although the results are not permanent, some women prefer this option because it prevents them from having to resort to chemical products. However, because the results are quite unpredictable, this option is often disregarded, particularly for serious surgeries like breast augmentation.

Plastic surgeons would be more than happy to offer a more “natural” option to their patients, especially those who have had mastectomies. In fact, because radiated tissue cannot tolerate implants made with artificial substances, women who have undergone mastectomies or lumpectomies must rely on prostheses and adapted-bras. Needless to say, these solutions are less than ideal.

Another research team at Georgetown University in the United States is focusing on various ways of extracting viable fatty tissue. Research conducted on mice has demonstrated that a molecule called Neuropeptide Y (NPY) increased when the mice were under stress. NPY seems to accelerate the production of fatty tissue, and the development of blood vessels necessary to their survival. These researchers were originally interested in the molecule for its potential in the treatment of obesity. However, some scientists believe that we could also use it to increase localized growth of fatty tissues. Although this hypothesis requires further research, it certainly does seem interesting.

These studies could one day revolutionize plastic surgery and reconstructive surgery! We’ll keep you posted!
