Human scalp hair follicles have PGE2 and its receptors, which might affect hair growth.

Stress stops hair growth in mice by causing early hair growth phase end and harmful inflammation through a specific nerve-related pathway.

A certain smell receptor in hair follicles can affect hair growth when activated by a synthetic sandalwood scent.

Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

The study found stem cells in minor salivary glands that can differentiate and are involved in tumor formation when exposed to tobacco.

Stem cell therapies show promise for treating various diseases but face challenges in clinical use and require better monitoring techniques.

Gray hair can potentially be reversed, leading to new treatments.

HPV infection is linked to better survival in advanced anal cancer, higher radiation doses improve survival, especially in HPV-negative patients, and prostaglandin E₂ pretreatment can protect mouse hair follicles from radiation damage.

Hair follicles can be used to quickly assess drug effects in cancer treatment.

Mesenchymal stem cells help improve wound healing by reducing inflammation and promoting skin cell growth and movement.

Stem cells regenerate tissues and their behavior varies by environment, suggesting the hematopoietic system model may need revision.

Mitochondria may influence how cells respond to radiation, affecting nearby non-irradiated cells.

Scarring alopecias are complex hair loss disorders that require early treatment to prevent permanent hair loss.

PRP injections help regrow hair, reduce hair loss, and increase hair thickness, but effects decrease without ongoing treatment.

Laser treatment improves hair density and increases growth factors in androgenetic alopecia.

Bimatoprost, a glaucoma medication, may also help treat hair loss.

Epigenetic changes control how adult stem cells work and can lead to diseases like cancer if they go wrong.

Some children who had stem cell transplants developed permanent hair loss, especially when treated with a drug called busulphan.

Cellular senescence has both cancer-blocking and cancer-promoting effects, and targeting senescent cells may improve health and lifespan.

PRGF treatment is safer and more effective for hair loss than topical minoxidil.

The document concludes that more research is needed to understand airway repair and to improve tissue engineering for lung treatments.

Blocking Wnt signaling in young mice causes thymus shrinkage and cell loss, but recovery is possible when the block is removed.

The research suggests new treatments for skin cancer could target specific cell growth pathways.

Plant-based products can improve hair and skin health without harmful side effects.

Different types of stem cells help maintain and heal skin.

Skin cancer often starts from Lgr5+ progenitor cells.

Activating Nrf2 in skin cells speeds up wound healing by increasing the growth of certain stem cells.

Retinoic acid-binding proteins in skin are regulated by β-catenin and Notch signalling.

Turning off the Lhx2 gene in mouse embryos leads to slower wound healing and scars.

The author now believes tricholemmal carcinoma is a rare type of infundibular squamous cell carcinoma and more research is needed on these tumors.
