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.

Vav2 and Vav3 proteins help control skin stem cell numbers and activity in both healthy and cancerous cells.

Some brain cancer cells avoid immune system detection, and certain treatments could target this to slow their growth; also, certain fat cell precursors help regenerate hair and skin after injury.

Keratin is crucial for keeping skin cells healthy and its changes can lead to diseases and affect cell behavior.

Dandruff is linked to increased T cells and weakened immune protection in hair follicles.

Certain immune cells are more common on the top of the head and might help predict or treat common hair loss.

Stem cell niches support, regulate, and coordinate stem cell functions.

Melanocytes are important for skin and hair color and protect the skin from UV damage.

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

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

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Certain immune cells, when activated by specific signals, can encourage hair growth.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Brain hormones significantly affect hair color and could potentially be used to prevent or reverse grey hair.

Immune checkpoint inhibitors can cause skin issues but are linked to better cancer outcomes.

Follicular Cell Implantation might become a new treatment for hair loss and could lead to advances in organ regeneration.

Transplanted hair follicles can change and adapt to new areas of the body, with the immune system possibly playing a role in this adjustment.

SOX2 is crucial for skin cell function and hair growth, and it plays a role in skin cancer and wound healing.

Blocking a specific immune cell signal can trigger hair growth.

Researchers created human cells that can turn into sebocytes, which may help study and treat skin conditions like acne.

The sebaceous gland has more roles than just producing sebum and contributing to acne, and new research could lead to better skin disease treatments.

New drugs for heart disease may be developed from molecules secreted by stem cells.

Paneth cells and intestinal stem cells work together metabolically for stem cell function and regeneration.

Low-dose radiation affects hair stem cell function and survival by changing their genetic material's structure.

Blocking certain immune signals can reduce skin damage from radiation therapy.

Fat tissue and a specific protein are crucial for healthy hair growth and maintenance.

Eating less can improve stem cell function and increase lifespan.

The shape of fibrous scaffolds can improve how stem cells help heal skin.

Stress may affect hair growth by influencing hair follicle development and could contribute to hair loss.
