How does stem cell technology rejuvenate old cells?

A new study by researchers from Stanford University School of Medicine has made stem cell technology increasingly popular in the field of continuous search and development of physiologically rejuvenating elders.

What are stem cells?

Stem cells are special human cells that can develop into many other types of cells. In some cases, they have the ability to repair tissue damage. Stem cells can be divided into two types:

  • Embryonic Stem Cells-Unused embryos from in vitro fertilization procedures, and later donated for scientific purposes, these cells can become a variety of cells.
  • Adult stem cells-There are two types: the first is from fully developed tissues such as brain, skin and bone marrow, and the second is artificial pluripotent stem cells, which have been processed in the laboratory and have the pluripotent properties of embryonic stem cells.

Stem cells are used in various researches, as well as in the treatment and transplantation of health care.

What is stem cell technology?

A study by Stanford University School of Medicine pointed out: "Old human cells will be restored to a more youthful and energetic state after being artificially induced and temporarily expressing a set 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 brings hope for effective treatment of various malignant and non-malignant diseases.

How does it bring youth to old cells?


According to research, Yamanaka factors are essential proteins in cell regeneration. These proteins are usually used to transform adult cells into so-called artificial pluripotent stem cells (or iPS cells). No matter where they come from, IPS cells can become Almost any type of cell in the body has become very important in the field of regenerative medicine and drug research.

Dr. Vittorio Sebastiano, assistant professor of obstetrics and gynecology at Stanford University’s Woods Family Faculty Scholar in Pediatric Translational Medicine, is the senior author of this study. He found that by strictly controlling the exposure of human cells to these proteins, many molecular features that cause aging can be reversed. The treated cells are almost indistinguishable from young cells.

By extracting cells from cartilage with and without osteoarthritis, it can be found that chondrocytes that have been exposed to Yamanaka factor reduce the secretion of inflammatory molecules and improve cell division and other cell functions.

Cell and protein contact, and RNA message

When it comes to cell-protein contact, there will be a repetition period of about two weeks, which is important for early embryonic cell development. The short-lived RNA information will be introduced into adult cells. This information is the production instructions for Yamanaka proteins. Then these Yamanaka proteins can reverse the developmental schedule of cells until they become similar to the original young cells.

Stem cells are the new skin care

The progress made by stem cell researchers has also promoted the rise of products that cater to the rejuvenation of stem cells, such as skin care products. S-CELL’s "Stem Cell Regeneration Mask" contains the highest quality ingredients that contribute to the production of healthy stem cells. With the help of stem cell technology, you can immediately start your healthy aging journey.
