Nail stem cells and Wnt signaling are important for fingertip regeneration but not sufficient for regenerating more complex limb structures.

Graft-versus-host disease is a complication where donor immune cells attack the recipient's body, often affecting the skin, liver, and gastrointestinal tract.

The research suggests that a specific skin gene can be controlled by signals within and between cells and is wrongly activated in certain skin diseases.

Telomere damage affects skin and hair follicle stem cells by messing up important growth signals.

New antiscarring strategies show promise, including drugs, stem cells, and improved surgical techniques.

The research created a detailed map of skin cells, showing that certain cells in basal cell carcinoma may come from hair follicles and could help the cancer grow.

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

Cell death shapes skin stem cell environments, affecting inflammation, repair, and cancer.

A new staining method shows a special area in the hair's skin layer with lots of proteoglycans.

African spiny mice can regenerate skin, hair, and cartilage, but not muscle, and their unique abilities could be useful for regenerative medicine.

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

Parathyroid hormone-related protein helps control hair growth phases in mice.

Tiny particles called extracellular vesicles could help with skin healing and hair growth, but more research is needed.

The arrector pili muscle might play a role in hair loss and needs more research to understand its impact.

Erythropoietin helps hair grow and could be a potential treatment for hair loss.

Gamma-ray exposure can cause long-lasting damage to hair follicles, affecting hair structure and color.

The document concludes that alopecia has significant social and psychological effects, leading to a market for hair loss treatments.

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

The document concludes that understanding the genes and pathways involved in hair growth is crucial for developing treatments for hair diseases.

Disruptions in hair follicle fibroblast dynamics can cause hair growth problems.

Wnt10b makes hair follicles bigger, but DKK1 can reverse this effect.

Hairless protein is crucial for healthy skin and hair, and its malfunction can cause hair loss.

Applying a special DNA plasmid to the skin can make it thicker and stronger.

Androgens can both increase body hair and cause scalp hair loss.

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

Gamma rays did not change hair follicle density but increased white and hypopigmented hairs in mice.

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.

The document concludes that a complete skin restoration biomaterial does not yet exist, and more clinical trials are needed to ensure these therapies are safe and effective.

A type of collagen helps hair grow by boosting cell growth and activating a specific hair growth pathway.

Boosting HGF signaling could improve the creation of hair follicles in lab-made skin.
