Discovering new stem cells in human skin and bones

On April 19, a group of researchers from Tohoku University, Japan, published the results of a study to detect a type of stem cells in the skin and bone marrow of adults.

The results are published in the journal of the National Academy of Sciences.

The group of scientists led by Professor Mari Dezawa said new cells, also called Muse cells, will be a new source of stem cells for scientific research and treatment.

Until now, scientists have only exploited stem cells from embryonic stem cells and artificial almighty cells.

Research has shown that Muse cells have a lower rate of development than embryonic stem cells and artificial Almighty cells, but there is little risk of malignant complications. This helps to apply to higher experimental treatment.

The team of researchers paid attention to Muse cells when they realized that the cells had similarities with embryonic stem cells.

After transplanting, Muse cells transformed into several chains, including the marrow, muscle and liver.

During the experiment on mice, when the Muse cells were implanted in damaged skin, muscle, and rat liver, the scientists found that Muse cells transformed into a suitable sequence, and stopped reproducing after two weeks. This is a big difference compared to embryonic stem cell transplantation and almighty cells.

In addition, Muse cells were implanted in non-malignant mouse testicles after six months, while embryonic stem cells produced tumors after eight weeks.
