Different ectodermal organs like hair and feathers regenerate differently, with specific stem cells and signals involved in their growth and response to the environment.

Testosterone and dihydrotestosterone can slow down the growth of certain hair follicle cells.

The study showed that some hair follicle stem cells wake up to grow hair while others stay asleep, and that the environment around them is important for hair growth.

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

Most hair loss in captive rhesus macaques is likely due to environmental and behavioral factors.

Fibroblast Growth Factors (FGFs) are important for tissue repair and regeneration, influencing cell behavior and other factors involved in healing, and are crucial in processes like wound healing, bone repair, and hair growth.

Prominin-1 expressing cells in the dermal papilla help regulate hair follicle size and communication but don't aid in skin repair.

Runx1 controls fat-related genes important for normal and cancer cell growth, affecting skin and hair cell behavior.

The microenvironment, especially mechanical forces, plays a crucial role in hair growth and could lead to new treatments for hair loss.

The document concludes that the hair cycle is a complex process involving growth, regression, and rest phases, regulated by various molecular signals.

The document concludes that the hair cycle is a complex process involving growth, regression, and rest phases, regulated by various molecular signals.

Both immature and mature fat cells are important for hair growth cycles, with immature cells promoting growth and mature cells possibly inhibiting it.

A pulsed electrical field safely and effectively increased hair growth.

HPV16 oncogenes disrupt the normal activity of hair follicle stem cells.

Dermal papilla cells are key for hair growth and color, influencing hair type and size, and their interaction with stem cells could help treat hair loss and color disorders.

Innate immunity genes in hair follicle stem cells might have new roles beyond traditional immune functions.

Hair growth is influenced by hormones and goes through different phases; androgens can both promote and inhibit hair growth depending on the body area.

Hair color production in mice is closely linked to the hair growth phase and may also influence hair growth itself.

The model showed that randomness accurately describes individual hair growth cycles and that synchronization can cause large fluctuations not seen in humans.

Doctors should diagnose hair loss by examining the patient and possibly doing tests, and then treat it based on the type, which may prevent permanent hair loss.

The extracellular matrix is crucial for controlling skin stem cell behavior and health.

The study concluded that changing the culture conditions can cause sika deer skin cells to switch from a flat to a 3D pattern, which is important for creating hair follicles.

The nervous system helps control stem cell behavior and immune responses, affecting tissue repair and maintenance.

Skin cell behavior is influenced by the tightness of nearby cells, affecting their growth and development.

Activin increases skin tumor formation, skin Tregs help hair growth, lymph-node removal doesn't improve melanoma survival, cells can revert to stem cells in wound healing, and skin bacteria produce peptides that may treat infections.

The circadian clock influences the behavior and regeneration of stem cells in the body.

Touch sensitivity in mouse skin decreases during hair growth due to changes in touch receptors.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

Inflammation helps stem cells repair tissue by directing their behavior.

Epigenetic changes are crucial for stem cell behavior in skin wound healing and their disruption may lead to cancer.
