Keratinocytes help keep hair follicle cells and skin cells separate in 3D cultures, which is important for hair growth research.

Epidermal stem cells are vital for skin healing and have potential for treating skin disorders.

Early-stage skin cells help regenerate hair follicles, with proteins SDF1, MMP3, biglycan, and LTBP1 playing key roles.

M-CSF-stimulated myeloid cells can cause alopecia areata in mice.

Ovine hair follicle stem cells can regenerate haired skin and may improve wool production.

Epidermal stem cells have potential for personalized regenerative medicine but need careful handling to avoid cancer.

TCF/Lef1 activity is essential for proper skin cell development and renewal.

Wnt signaling is essential for forming the skin's spinous layer through a BMP-FGF pathway.

Psoriasis causes changes in certain keratins and shrinks sebaceous glands in the scalp.

Certain cells outside the hair follicle's bulge area can quickly regenerate damaged hair follicles, potentially helping to reduce hair loss from cancer treatments.

Stem and progenitor cells in the eye have different division rates and locations, affecting how they respond to injury.

The research shows a potential way to regenerate hair using adult cells that have been grown and guided to produce new hair fibers.

Calcium signaling in skin cells is crucial for communication and regeneration.

A mutation in mice causes hair loss and skin issues due to a defect in a gene affecting cell adhesion.

Stem cells regenerate tissues and their behavior varies by environment, suggesting the hematopoietic system model may need revision.

Two fibroblast types shape skin structure and repair differently.

Telomerase-positive cells are mainly in the bulb matrix and outer root sheath of hair follicles.

Conditioned medium from keratinocytes can improve hair growth potential in cultured dermal papilla cells.

Hair germ cells differ from epidermal cells in keratin expression, and specific keratins form after hair differentiation.

Fat-related cells are important for initiating hair growth.

The document concludes that ERBB2 mutations are common in extramammary Paget disease and may respond to systemic treatments like cancer immunotherapy.

Hair differentiation starts earlier than thought, involving multiple type-II keratins.

Cultured dermal papilla cells can regenerate hair follicles and sustain hair growth.

The document outlines criteria to identify and differentiate neoplasms based on follicular characteristics.

Scientists found ways to identify and collect skin stem cells, which vary by skin area and are delicate.

Human hair follicles can produce stem cells that turn into heart muscle cells.

Routine culture medium boosts cell growth, but dermal hair papilla and sheath cells produce less collagen than fibroblasts.

Immortalized human dermal papilla cells were created that grow better and can still help form hair.

The treatment was ineffective in humans.
