How Stem Cell Technology Rejuvenates Old Cells

The continuous search and development for biological solutions that cater to reviving the youth in aging people have begun to welcome stem cell technology through a new study by researchers at the Stanford University School of Medicine.

What are Stem Cells?

Stem cells are special human cells that have the ability to develop into many other types of cells.  They also have the ability to repair tissue damages in certain cases. Stem cells are divided into two forms:

  • Embryonic stem cells - come from unused embryos resulting from an in vitro fertilization procedure and that are donated to science. These cells are can turn into more than one type of cell.
  • Adult stem cells - come in two more types: The first type comes from fully developed tissues, like the brain, skin, and bone marrow. The second type is induced pluripotent stem cells which have been manipulated in a laboratory to take on the pluripotent characteristics of embryonic stem cells. 
  • Stem cells are used in various research, and in therapies and transplants when it comes to healthcare.

    What is Stem Cell Technology?

    Research from the Stanford University School of Medicine found out that “old human cells return to a more youthful and vigorous state after being induced to briefly express a panel of proteins involved in embryonic development”. 

    Stem cell technology is a rapidly developing field that combines the efforts of cell biologists, geneticists, and clinicians and offers hope of effective treatment for a variety of malignant and non-malignant diseases.

    How it helps bring the youth in old cells

    Yamanaka factors

    According to the study, Yamanaka factors are the proteins that play a vital role in rejuvenating the cells. These proteins are commonly used to transform an adult cell into what are known as induced pluripotent stem cells, or iPS cells. IPS cells can almost turn into any type of cell in the body, regardless of the origin. They've become important in regenerative medicine and drug discovery.

    According to Vittorio Sebastiano, PhD, assistant professor of obstetrics and gynecology and the Woods Family Faculty Scholar in Pediatric Translational Medicine and a senior author of the study, it is found that by tight control of the old human cells’ exposure to the proteins, it is able to rewind many of the molecular hallmarks of aging and renders the treated cells nearly indistinguishable from their younger counterparts.

    There is also the isolation of cells from the cartilage of people with and without osteoarthritis and found temporary exposure to the Yamanaka factors reduced the secretion of inflammatory molecules and improved the cells’ ability to divide and function.

    Exposure and RNA messages

    When talking about the exposure of the cells to the proteins, there is a repetitive period of about two weeks important to early embryonic development. Short-lived RNA messages are introduced into the adult cells, and these messages encode the instructions for making the Yamanaka proteins. The proteins are then able to rewind the cells'  developmental timeline until they resemble the young cells from which they originated.
