Scientists may have made a breakthrough in the treatment of baldness by using a tiny RNA particle to stimulate hair growth. The study revealed that hair follicles become stiff with age, making it harder for hair to grow. However, by softening the stem cells through the production of a specific RNA called miR-205, researchers at Northwestern University in Illinois were able to promote hair growth in mice, regardless of their age.
Incidentally, stem cells are also linked to the graying of hair, as we reported recently in Medical News Today
The researchers genetically engineered the stem cells to produce more miR-205, effectively softening the hair follicles of mice, leading to significant hair growth within only 10 days. This finding offers new insights into the regulation of cell processes and their impact on hair growth. While researchers conducted the study in mice, it lays the foundation for potential future treatment for baldness in humans.
Dr. Rui Yi, a senior author of the study, highlighted the significance of the findings, saying, “These are not new stem cells being generated. We are stimulating the existing stem cells to grow hair. A lot of times we still have stem cells, but they may not be able to generate the hair.”
The impact of hair loss goes beyond aesthetics and can greatly affect a person’s self-esteem and quality of life. It’s a common concern, and the potential availability of a treatment is likely to be highly sought after. However, extensive safety and efficacy trials involving humans are needed before any treatments are available to the public.
