According to a Danish study, injections of fat enriched with stem cell led to considerably higher retention of volume when compared with standard procedures. This study may modernize the field of reconstructive surgery.

Fat attaches with the stem cells of the patient and retains 81% of their initial volume after 121 days. The figure was compared with 16% for a control group that didn't use these cells. The study included 10 researchers who were involved in the research at Copenhagen University Hospital in Denmark. The study was published in the Lancet medical journal today.

To increase the volume of fats in other area of the body, fat grafting is used. This is a wide-spread method for reconstructive surgery. According to the studies done earlier, it was found that nearly 80% of the transferred fat doesn't survive.

J. Peter Rubin and Kacey G. Marra, professors of plastic surgery at the University of Pittsburgh, said, "These therapies could revolutionize breast reconstruction after cancer and reconstruction of deformities after trauma".

The sample of fat tissue was collected by the researchers from volunteers' stomach by liposuction. The fat was enriched with the stem cells possessed by them, and injected the grafts in the upper arms.
