The model can effectively test gene functions and drug responses in human skin.

β-catenin in the dermal papilla is crucial for normal hair growth and repair.

ILK is essential for skin development, pigmentation, and healing.

The flap assay grows the most natural hair but takes the longest, the chamber assay is hard work but gives dense, normal hair, and the patch assay is quick but creates poorly oriented hair with some issues.

Melanocyte stem cells in hair follicles are key for hair color and could help treat greying and pigment disorders.

Human sebaceous glands can grow back in skin grafts on mice and work like normal human glands.

Androgens can both stimulate and cause hair loss, and understanding their effects is key to treating hair disorders.

Advanced human skin models improve drug development and could replace animal testing.

Ephrin-A3 helps increase and speed up hair growth in baby mice.

Mutations in the DSG4 gene cause fragile, sparse hair in humans, mice, and rats.

Using fat stem cells and blood cell-rich plasma together improves healing in diabetic wounds by affecting cell signaling.

A specific group of skin stem cells was found to help maintain hair follicle cells.

Hair follicle dermal stem cells are key for regenerating parts of the hair follicle and determining hair type.

Aging changes hair stem cells and their environment, leading to gray hair and hair thinning, but understanding these changes could help develop treatments for hair regeneration.

EdnrB signaling helps melanocyte stem cells regenerate and could be targeted to treat pigmentation issues.

Adding human fat-derived stem cells to hair follicle grafts greatly increases hair growth.

Too much Smad7 changes skin and hair development by breaking down a protein called β-catenin, leading to more oil glands and fewer hair follicles.

Reducing FOXA2 in skin cells lowers their ability to grow hair.

Jumonji genes are important for development and their mutations can cause abnormalities, especially in the heart and brain.

Certain signals and genes play a key role in hair growth and regeneration, and understanding these could lead to new treatments for skin regeneration.

The conclusion is that teeth, hair, and claws have similar stem cell niches, which are important for growth and repair, and more research is needed on their regulation and potential markers.

Mice lacking fibromodulin have disrupted healing patterns, leading to abnormal skin repair and scarring.

Ingenol mebutate gel changes gene expression related to skin development and immune response in actinic keratosis.

Men's sensitivity to male hormones might affect how severe COVID-19 gets for them.

The experiment showed that human skin grown in the lab started to form early hair structures when special cell clusters were added.

The study concluded that changing the culture conditions can cause sika deer skin cells to switch from a flat to a 3D pattern, which is important for creating hair follicles.

Researchers isolated a new type of stem cell from mouse skin that can renew itself and turn into multiple cell types.

Hair follicles can help wounds heal faster and this knowledge could be used to treat chronic skin ulcers, with a potential use of a special stem cell hydrogel to enhance healing.

The Foxn1(-/-) nude mouse shows disrupted and expanded skin stem cell areas due to high Lhx2 levels.
