Cells Found in Adult Males Have Same Properties As Embryonic Stem Cells -  Sperm Producing Cells From Testicles Work The Same -Researchers From Germany Say

Cells Found in Adult Males Have Same Properties As Embryonic Stem Cells -  Sperm Producing Cells From Testicles Work The Same -Researchers From Germany Say

Embryonic Stem Cells
From Mice

Researchers in Germany believe they have isolated stem cells from the testicles of adult mice that appear similar to embryonic stem (ES) cells.  The researchers hope that they can isolate similar cells in male adults that can be used in place of embryonic stem cells.  If these stem cells can be used in place of human embryonic stem cells, it would remove a stumbling block for research into such diseases as Parkinson’s and Alzheimer’s. 

Stem cells are the body’s building blocks, and embryonic stem cells are the most useful because they have the ability to become any type of cell within the human body.  The researchers believe they could provide an alternative source of stem cells for growing genetically matched cells.  This would likely be more acceptable than using embryos. 

Gerd Hasenfuss and colleagues from the Georg August University of Göttingen are responsible for this research.  They said “This would avoid the technical and ethical difficulties associated with generating cells from human embryos."

 

Previous research has indicated that certain cells in the testicles of newborn mice were able to generate into numerous tissue types.  This is the first time that researchers have isolated such cells in adults.

These cells are “sperm-producing” cells, and the team calls them multipotent adult germline stem cells (maGSCs).  Like ES cells, these maGSC cells can spontaneously differentiate into the three basic tissue layers of the embryo. 

It is hoped these cells can substitute for ES uses.  The research is published in the journal Nature.
