Scientists have developed a powerful new technique that allows them to observe how individual cells manufacture proteins during aging, offering an unprecedented glimpse into the hidden molecular activity of stem cells in living tissue. As a result of the research, conducted at the Institute for Regenerative Medicine in Switzerland, scientists were able to observe aging unfold inside individual epidermal stem cells.

What scientists saw was the intricate choreography within stem cells and how those molecular dance steps slow and change with age. The team of Swiss scientists has concluded that the process of aging reshapes how skin stem cells manufacture proteins. The findings are published in the journal Molecular Cell.
