Hair follicle development involves complex interactions between skin layers and cells, but many details are still unknown.

Scientists created hair-growing skin models from stem cells, which could help treat hair loss and skin diseases.

Skin and hair can help us understand organ regeneration, especially how certain stem cells might be used to form new organs.

YAP1 is important for skin regeneration and may affect skin disorder treatments.

Mice with LSS deficiency showed hair loss and cataracts, similar to humans, and can help in understanding and treating this condition.

Artificial dermal template treatment can stimulate complete skin and hair follicle regrowth.

Researchers created a quick, cost-effective way to make skin-like tissue from hair follicles and fibroblasts.

Mice with the 'lanceolate hair' mutation have abnormal hair and skin similar to human Netherton's syndrome.

Type 1/17 inflammation in psoriasis increases skin cell growth due to a molecule that could be a new treatment target.

A gene mutation in mice causes skin defects and early death.

Overexpression of a specific receptor in mice skin causes skin thinning, early skin barrier formation, eye issues, and hair loss.

The new patch made of cell matrix and a polymer improves wound healing and supports blood vessel growth.

Epidermal stem cells are crucial for skin health and problems with them can cause issues like poor wound healing, cancer, and aging.

Atopic dermatitis shows a link between skin layers in inflammation, detectable with detailed gene analysis.

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.

The S100A4 protein is more common in psoriatic skin and could be a target for treating psoriasis.

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.

Regenerative therapies show promise for treating vitiligo and alopecia areata.

Lab-grown nail cells show characteristics similar to natural nail and hair.

Hair follicle stem cells can generate all hair cell types, skin, and sebaceous glands.

A gene mutation causes lanceolate hair in rats by disrupting hair shaft integrity.

Understanding intermediate filaments helps explain hair health and related diseases.

The reconstructed skin model from hair follicles functions like human skin in processing chemicals and can be used to test ingredient safety.

Skin organoids are a promising new model for studying human skin development and testing treatments.

Valproic acid may help hair grow and could be a safe treatment for hair loss.

Mice are useful for researching human hair loss and testing treatments, despite some differences between species.

Human hair provides more UV protection when aligned and at higher angles, but the scalp still gets UV exposure.

Scientists created a 3D skin model to study a chronic skin disease and test treatments.

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

Adding hyaluronic acid helps create larger artificial hair follicles in the lab.
