Cellular aging has been reversed
Source:
Throughout history, mankind has searched for the secret of eternal youth. But only scientists from Stanford University may have gotten a step closer to the desired. Recently a team of researchers announced that they managed to rejuvenate human cells using the mechanism used to create stem cells. The results showed that the method is designed to reverse the error in copying of DNA and cells to restore youthful, really eliminates the signs of aging and restores cellular energy. Scientists hope that in the future the developed method will help in the treatment of diseases caused by aging of tissue cells. Moreover, the obtained results is an important and significant step to defeating aging.
What is the Yamanaka factors?
To restore youth to cells was possible with the help of the Yamanaka factors – proteins that turn usually . Moreover, as the authors of the study, the Yamanaka factors play an important role in the establishment of embryonic cells.
The Aim of the procedure is rejuvenation of the cells was the elimination of the negative factors that occur with aging of the body. During the work published in the journal , the use of Yamanaka factors allowed the scientists to reverse the weakening of the cellular systems, which occurs with aging. Recall that today scientists around the world are working to develop an effective way of anti-aging. Read more about what the researchers have managed to achieve, read .
the Aging process which all of us would like to avoid.
Writes , in 2006, the Signa Yamanaka, stem-cell researcher from Kyoto University (Japan), has struck biologists, demonstrating that the fate of the cells can be changed by using the set of four transcription factors, agents that activate the genes that determined scientist. Cell, measured by the Yamanaka factors loses its identity and returns to the embryonic state. Errors in the genome that accumulate as aging cells are also lost in the process of rejuvenation. The work of Dr. Yamanaka was awarded the Nobel prize in medicine in 2012.
How to rejuvenate the cells?
In 2016, Juan Carlos Izpisua Belmonte from the Institute of biological research Salk in San Diego found that two effects of the Yamanaka factors is the Erasure of the identity of the cells and can be separated. Moreover, lower dose of Yamanaka factors provides only a change in the age of the cell. However, these results were obtained on cells of laboratory mice, not people.
Perhaps in the future people will stay longer young and healthy
In the new work, scientists from Stanford University have described a possible method of delivery of Yamanaka factors in cells taken from patients. The authors argue that the dosage of the cells by the Yamanaka factors during the short period of time, the cells preserve their identity and . In the course of work, scientists have removed the old cartilage cells of patients with osteoarthritis and found that after low doses of Yamanaka factors cells no longer secrete inflammatory factors that trigger the disease.
The Researchers also found that human muscle stem cells, which are damaged during muscle weakness – sudden loss of strength and muscle weakness, accompanied by a significant reduction or cessation of motor activity can be restored. Thus, the discovery of today can allow to develop a therapeutic agent for the treatment of osteoarthritis and other diseases.
Cells, you can regain lost youth, researchers found
