Should medical treatments for skin conditions be tailored differently for men and women?
A study published in Nature by researchers from the Université libre de Bruxelles and the University of Cambridge found that skin stem cell renewal differs between male and female mice. Female mice showed highly synchronized cell division, while male mice showed more individual cell behavior.
Why it matters
The findings suggest sex-specific mechanisms may influence how skin heals and how skin disease develops. Initial tests on human skin cells in the lab indicated similar mechanisms may be at play.
The study tracked epidermal stem cells over five months in mice, with the outer skin layer fully renewing in about 6-7 weeks. Results come from a small group of mice, and the human relevance remains under investigation through initial lab tests on human skin cells.
The players
Université libre de Bruxelles
A public research university in Brussels, Belgium, whose researchers led the study on sex differences in skin stem cell renewal.
University of Cambridge
A research university in Cambridge, England, whose experts co-led the study on how sex hormones shape skin stem cell behavior.
The details
Researchers used microscopy to image living cells through the skin and removed testes or ovaries in mice, then replaced hormones to observe effects on skin cell production. Removing testosterone-producing organs caused male skin cells to behave more like female cells, while removing estrogen-producing organs eliminated most coordinated actions seen in females.

The Big Picture
This study adds a sex-based dimension to skin stem cell research, which has largely treated renewal as uniform across individuals. It opens the door to examining whether sex hormones influence skin disease and healing in ways previously overlooked.
If confirmed in humans, findings could eventually lead to treatments tailored by sex for burns, wounds, skin conditions, and skin cancers. Such therapies remain years away and depend on the next stage of research.
The takeaway
Biological differences between sexes can shape how tissues repair and renew themselves, a factor that future skin treatments may need to account for. Staying informed on follow-up human studies will show whether these mouse findings translate to patient care.
What happens next
Researchers plan to expand analysis to human skin cells and to investigate sex differences in the formation and progression of skin cancers.
