Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

Wnt signaling is crucial for skin and hair development and its disruption can cause skin tumors.

Skin-derived stem cells grow faster and are easier to obtain than hair follicle stem cells, but both can become various cell types.

Understanding skin structure and development helps diagnose and treat skin disorders.

The document concludes that skin stem cells are important for hair growth and wound healing, and could be used in regenerative medicine.

The skin has a complex immune system that is essential for protection and healing, requiring more research for better wound treatment.

Memory T cells in the skin balance staying put and moving into the blood, clustering around hair follicles, and increasing in number after infection.

Certain types of T cells are essential for healthy skin and play a role in skin diseases, but more research is needed to improve treatments.

Using skin stem cells and certain molecules might lead to scar-free skin healing.

Marine-derived saccharides may help reduce aging effects on skin and hair by promoting cell growth and collagen production.

Vav2 changes how hair follicle stem cells' genes work as they age, which might improve regeneration but also raise cancer risk.

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

Fetal skin heals without scarring due to unique cells and processes not present in adult skin healing.

Changes in testosterone and estrogen receptor genes can affect how men age, influencing body fat, hair patterns, and possibly leading to skin disorders.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Lanyu pigs show that partial-thickness wounds can partially regenerate important skin structures, which may help improve human skin healing.

Fat cells are important for healthy skin, hair growth, and healing, and changes in these cells can affect skin conditions and aging.

Hair follicle regeneration needs special conditions and young cells.

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

SOX9 helps determine stem cell roles by interacting with DNA and proteins that control gene activity.

Runx genes are important for stem cell regulation and their roles in aging and disease need more research.

Dermoscopy is an effective tool for accurately detecting skin cancers.

The skin's microbiome helps hair regrow by boosting certain cell signals and metabolism.

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

Skin problems in the elderly are unique and may indicate other diseases, involving changes in skin, hair, nails, and increased cancer risk.

Scientists created stem cells that can grow hair and skin.

Runx1 affects hair growth, cancer development, and autoimmune diseases in epithelial tissues.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

Nude mice with grafted human skin developed scars similar to human hypertrophic scars.

15-lipoxygenase helps keep skin healthy by reducing inflammation.
