Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

Light can turn on hair growth cells through a nerve path starting in the eyes.

Understanding how hair follicle stem cells work can help find new ways to prevent hair loss and promote hair growth.

Improving the environment and cell interactions is key for creating human hair in the lab.

Skin bacteria, specifically Staphylococcus aureus, help in wound healing and hair growth by using IL-1β signaling. Using antibiotics on skin wounds can slow down this natural healing process.

The document explains different types of hair loss, their causes, and treatments, and suggests future research areas.

The document concludes that mouse models are crucial for studying hair biology and that all mutant mice may have hair growth abnormalities that require detailed analysis to identify.

Skin fat plays a key role in immune defense and healing beyond just storing energy.

The protein StAR is found in 17 different organs and can affect hair loss and brain functions, but its full role is not yet fully understood.

Regenerative pharmacology, which combines drugs with regenerative medicine, shows promise for repairing damaged body parts and needs more interdisciplinary research.

Disrupting Acvr1b in mice causes severe hair loss and thicker skin.

Some natural compounds may help overcome drug resistance in certain cancers, but more research is needed.

Nano-sized plant-based chemicals could improve cervical cancer treatment by being more effective and causing fewer side effects than current methods.

Fat cells are important for tissue repair and stem cell support in various body parts.

Hormones and neuroendocrine factors control hair growth and color, and more research could lead to new hair treatment options.

Using fat stem cells and blood cell-rich plasma together improves healing in diabetic wounds by affecting cell signaling.

Lizards can regrow their tails, and studying this process helps understand scar-free healing and limb regeneration.

Using a gene therapy with the Sonic Hedgehog gene helps mice regrow hair faster after losing it from chemotherapy.

Different species and human skin models vary in their skin enzyme activities, with pig skin and some models closely matching human skin, useful for safety assessments and understanding the skin's protective roles.

Scalp cooling can help prevent chemotherapy-induced hair loss with a 50-90% success rate and is safe for patients.

Aging in hair follicle stem cells leads to hair graying, thinning, and loss.

The conclusion suggests that prostate cancer should be classified by castration status and that new therapies targeting androgen receptor signaling show promise.

Spiny mice are better at regenerating hair after injury than laboratory mice and could help us understand how to improve human skin repair.

The document concludes that there are various treatments for different types of alopecia, but more research is needed for evidence-based treatments.

MicroRNAs are important for skin health and could be targets for new skin disorder treatments.

Smad1 and Smad5 are essential for hair follicle development and stem cell sleepiness.

Different hair growth problems are caused by genetic issues or changes in hair growth cycles, and new treatments are being developed.

Dogs could be good models for studying human hair growth and hair loss.

Further research is needed to improve hair regeneration using stem cells and nanomaterials.

Ca_v1.2 affects hair growth and could be a target for hair loss treatments.
