The Role of Stem Cells in Beauty—Today and Tomorrow

page 6 of 8It is important to protect stem cells’ DNA as research seems to show (and it has to be confirmed) that their DNA could be less robust than the DNA of differentiated cells. The repair rate of that DNA in particular seems to be less.
Protecting the telomeres (the end pieces of a chromosome, which, when they become too short, prevent the cell from dividing thus leading it to die) is especially important.
For now, one strategy is to maintain stem cells in a quiescent state, in their niche, well attached with ligands [molecules or molecular groups that bind to another chemical entity] at the bottom of the basal membrane, under optimal conditions.
Using Stem Cells to Study Active Raw Materials
The development of novel stem cell-based in vitro models allows better exploration of actives, from both an activity and a toxicity standpoint.
Using Human Stem Cells to Beautify the Human Body
Many people believe that human stem cells are actually used in cosmetic treatments. As of today, this is not the case, and it is difficult to forecast how or if we will ever be able to “inject” human stem cells into the skin with the tools that are currently at our disposal.
