Latest news: “Good” fat implants for less weight gain

We have recently learned (around August 26th more specifically) that a group of American researchers from the University of California Berkeley has satisfactorily concluded tests on mice during which they managed to implant “good” brown fat cells whose role was to promote weight loss. The scientists said that their mission was completed successfully. Mice that had brown fat implant did actually lose some weight.

These researchers point out that there are two types of fat cells: brown fat cells which are energy consuming and therefore beneficial, and white fat cells which are considered as harmful. Thus, researchers have been able to recreate brown fat cells in the laboratory before implanting them in the body of a number of mice so that to prevent weight gain and lower blood glucose levels. The results of their tests on these mice were positive.

To date, these human fat cells were only implanted in mice, and results are very encouraging for researchers at the University of California Berkeley. “This is a research field that is very prominent presently,” declared the author of the study, Andreas Stahl of Berkeley. “We were the first to implant in mice an artificial deposit of brown fat cells and to show that such cells drew the expected beneficial effects on body temperature and on metabolism”.

Finally, and to explain the phenomenon, researchers said that they were able to obtain beige fat cells, namely white cells that are energy consuming and therefore identical to brown cells, by placing white stem cells on a protein and gel thread. Afterwards, they injected such beige fat cells in a group of mice. These new cells have had the effect of slightly increasing the body temperature of these mice. This thermogenesis function has proven to be effective when researchers fed the mice that were implanted with these cells. As a result, the mice to which beige fat cells were implanted gained less weight than other mice fed but which no implant has been done. It shows thus that we have here an encouraging study which needs to be continued further before such operation can be considered on humans.
