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.

UVB radiation harms hair growth and health, causing cell death and other changes in human hair follicles.

Stem cells and their surrounding environment in hair follicles work closely together, affecting hair growth and having implications for cancer and tissue regeneration.

The research confirms that Hidradenitis Suppurativa is characterized by increased inflammation, disrupted skin cell organization, and abnormal metabolic processes.

Increased cell death and reduced cell growth in hair follicles contribute to baldness.

ePUKs could be valuable for regenerative medicine due to their wound healing abilities.

Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

High levels of testosterone and 5α-DHT can lead to cell death in cells important for hair growth.

The document concludes that the skin's immune system is complex, involving interactions with hair follicles, nerves, and microbes, and can protect or cause disease, offering targets for new treatments.

Quercetin significantly helps hair growth by activating hair follicles and improving blood vessel formation around them.

Caspases are enzymes important for both cell death and various non-lethal cell functions, affecting head development and hair growth, with different caspases playing specific roles.

Small proline-rich proteins and trichohyalin help make epithelial tissues tougher and more flexible.

Green tea extract helps prevent cell death and supports cell survival in hair cells exposed to a chemotherapy drug.

Dexpanthenol helps human hair follicle cells grow by preventing aging and death, and by supporting growth signals.

Finasteride helps hair growth by decreasing cell death in hair follicles.

Phaeodactylum tricornutum extract helps hair follicle cells grow by activating the ERK1/2 pathway.

A tripeptide-copper complex may help hair grow by increasing cell growth and decreasing cell death.

Ionizing radiation damages human hair follicles by stopping cell growth, causing cell death, disrupting color, and increasing stress and damage markers.

Stem cells help remove dead cells to keep tissues healthy by balancing cell replacement and clearance.

We need more research to better understand human hair follicle stem cells for improved treatments for hair loss and skin cancer.

A chemical called 5-Bromo-2′-deoxyuridine caused rapid hair loss in mice by killing certain skin cells through a specific cell death pathway.

Isotretinoin's effects and side effects, like birth defects and depression, might be due to it causing cell death in various cells.

The conditions alopecia areata, primary sclerosing cholangitis, and ulcerative colitis may be linked by shared autoimmune and cell death mechanisms.

iPSC-derived stem cells on a special membrane can help repair full-thickness skin defects.

Gata6 is important for protecting hair growth cells from DNA damage and keeping normal hair growth.

Inflammation plays a key role in activating skin stem cells for hair growth and wound healing, but more research is needed to understand how it directs cell behavior.

RSPO1 mutations in certain patients lead to skin cells that don't develop properly and are more likely to become invasive, increasing the risk of skin cancer.

Regulating cell death in hair follicles can help prevent hair loss and promote hair growth.

Researchers found four key stages of cell development that are important for hair growth and shedding in cashmere goats.
