Aging skin shows thinner layers, fewer hair follicles, and new biomarkers like increased space between cells and smaller sebaceous glands.

The "Two-Cell Assemblage" assay is a new, simple method to identify substances that may promote hair growth.

High concentration Minoxidil and Carboxygas effectively treated resistant hair loss with no side effects.

Injected cells show potential for hair growth.

Nanoparticles can be used to deliver drugs to hair follicles, potentially improving treatments for conditions like acne and alopecia, and could also be used for vaccine delivery and gene therapy.

The research found that the gene activity in mouse skin stem cells changes significantly as they age.

Hair follicle stem cells can turn into many cell types and may help repair nerve damage and have other medical uses.

A protein called EGFR protects hair follicle stem cells, and when it's disrupted, hair follicles can be damaged, but blocking certain pathways can restore hair growth.

Changes in skin bacteria can affect hair loss and new treatments targeting these bacteria may prevent balding without sexual side effects.

New hair loss treatments show promise, but more research is needed to confirm their effectiveness.

Fetal scalp cells have more regenerative genes than adult cells, and decellularized muscle matrix is better for muscle repair than commercial alternatives.

Mice without the vitamin D receptor have bone issues and other health problems, suggesting vitamin D is important for preventing various diseases in humans.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

The document concludes that understanding how the skin's immune system and inflammation work is complex and requires more research to improve treatments for skin diseases.

Certain mature cells in mouse lungs can turn back into stem cells to aid in tissue repair.

Changing the environment around stem cells could help tissue repair, but it's hard to be precise and avoid side effects.
