Stem cells: waste – to income!
Stem cells will be obtained from liposuction waste
Copper newsScientists from the United States have found a way to convert adipose tissue cells into stem cells, Mercury News reports.
A report on the research of Stanford University staff (Stanford University) is published in the Proceedings of the National Academy of Sciences.
The researchers used a method developed in 2007 by specialists from Kyoto University of Japan, who managed to convert skin cells into induced pluripotent stem cells.
Stanford University researchers used adipose tissue as a starting material instead of skin to obtain stem cells. The cells of this tissue are more versatile and adaptable, which facilitates and accelerates their reprogramming.
In addition, adipose tissue is one of the most accessible to obtain. The liposuction procedure (removal of adipose tissue) takes about 30 minutes and is performed under local anesthesia. The US population traditionally suffers from problems caused by excess weight. Liposuction in this country is the most frequently performed procedure by plastic surgeons. In 2006, American surgeons performed more than 400 thousand such operations. (One of these surgeons even refueled the car with biodiesel from human fat –VM.)
The method used by American scientists is not yet suitable for clinical use, since viruses are used to transform cells by transferring genetic information, which can damage the DNA of cells, and thereby trigger the growth of malignant tumors. According to one of the authors of the study, Joseph Wu, at the next stages of the work, scientists plan to obtain stem cells without resorting to the use of viruses.
Several research groups from the USA and Australia have previously managed to convert adipose tissue cells into cells of other tissue types, such as muscle. Stanford University specialists were able to obtain induced pluripotent stem cells from adipose tissue, which then differentiated into cells of nervous and muscular tissues, as well as intestinal epithelium.
