American scientists from the University of California in Los Angeles discovered a cell mechanism explaining why the fat layer on the abdomen increased with age. The study was published scientifically magazine Science.
Experts have demonstrated a special Tom cell-premise-premise (CP-SA), which is activated at an average age and actively began to produce new fat cells. These cells do not practically work in young organisms, but with age, their activity increases sharply.
“Aging initiates the process of the emergence of a new adult stem cell, especially producing fat cells, especially in the abdomen,” he explained.
Mouse experiments showed that CP-SA activation is performed by the LIFR signal pathway (a receptor for the inhibiting factor of leukemia). It can become a promising direction to prevent this path against the age weight set.
While the “old” stem cells continue to actively produce fat cells during the transplantation of young mice, it is interesting that the “young” cells in the old organism are not active.
The analysis of human cells confirmed the presence of similar CP-AS in the fat tissue of middle-aged people. This discovery explains that the body’s composition changes even when maintaining weight with age – muscle mass decreases and the fat layer increases.
