The key to increased hair growth lies, among other things, in the MikroRna, a group of molecules that, among other things, controls the activity of your genes – so whether a gene produces too much, too little or just the right amount of proteins.
Old stem cells get new energy
In the study, which was conducted in mice, the scientists found that they could soften the stem cells in the hair follicles of the mice by increasing production of the molecule MiR-205.
The special thing is that the molecule stimulates stem cells that are already present in the hair follicles and allow the hair to grow. The molecule therefore only activates the old, stiff stem cells that had fallen asleep with age.
In the lab, the success was clear to see:
“After 10 days, the hair started growing again,” says Rui Yi, a professor of dermatology at Northwestern University Feinberg School of Medicine, in a press release.
Yi and the rest of the research team used genetically modified mice and advanced microscopic instruments to measure the stiffness of the stem cells.
It remains to be seen whether the method can also be used for the human scalp.
‘We then want to test whether we can stimulate hair growth in mice by administering miR-205 directly into the skin using nanoparticles,’ says Yi.
‘If that is successful, we will set up experiments to test whether this microRNA can also promote hair growth in humans.’
