Scientists at Stanford Medical School claim that subcutaneous fat is liquid gold for medicine, as it is the best source of stem cells. In addition, almost any person is ready to get rid of 2-3 kilograms.
For several years now, scientists have been trying to find the best source of stem cells. For these purposes, cells of the skin, connective tissue, bone marrow, blood, hair and even teeth were used.
Researchers at Stanford Medical School have shown that stem cells can be obtained from fat cells the fastest. From 10 thousand fibroblasts of connective tissue, only one stem cell can be isolated, spending a whole month on it. And when scientists from Stanford collected two liters of fatty tissue from four people aged 40 to 65 after liposuction and processed it, leaving only stem cells, it all took only two days.
As one of the participants in the work Ning Sun explains, fat cells are not highly differentiated, for this reason it is easier to return them to an early stage of development. They are more like embryonic cells than fibroblasts, which are very difficult to reprogram. To turn adult body cells into stem cells, it is necessary to amplify four specific genes in them, and adipose tissue stem cells already have high expression of two of the four genes, km.ru writes.
“Subcutaneous fat is liquid gold for medicine! - said Dr. Michael Longheiker. “In the United States, from 30 to 40 percent of citizens are obese, and almost any person is ready to get rid of a couple of kilograms.”
