The timing of when the gene Bmal1 is active affects aging and survival, with its absence during development, not adulthood, leading to premature aging.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

Different types of skin cells play specific roles in development, healing, and cancer.

Men are more likely to have severe COVID-19 cases and fatalities than women due to factors like lifestyle, aging, and biological differences.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Finasteride effectively treats baldness but may cause sexual side effects.

Fibroblast growth factor receptor signaling controls cell development and repair, and its malfunction can cause disorders and cancer, but it also offers potential for targeted therapies.

The AUTS2 gene is linked to neurological disorders and may affect human brain development and cognition.

New single-cell analysis techniques are improving our understanding of stem cells and could help in treating diseases.

FGF signaling is a promising target for developing treatments for wounds, metabolic diseases, and cancer.

The article concludes that better understanding gene regulation related to seasonal changes can offer insights into the mechanisms of seasonal timing in mammals.
