Flatworms, the masters of regeneration — but nothing can happen without stem cells Flatworms, the masters of regeneration — but nothing can happen without stem cells June 03, Brain Stem Cells Planarians are known as masters of regeneration: This ability relies on a large number of pluripotent stem cells. To further investigate the mechanisms that enable planarians to maintain their stem cell pool over generations, scientists have now established a method for analysing the composition of planarian stem cells and the turnover of their proteins. They discovered a protein that is not only required for the maintenance of the stem cell pool in planarians, but might also be active in the pluripotent stem cells of mammals.

The first ten men mentioned in the Bible, Adam through Noah except Cain and Abel , lived on average more than years Genesis 5: Methuselah lived for years. This was the maximum, but by no means exceptional. However, already in antediluvian time God fixed the living day of man to years.
