Scientists created stem cells that can grow hair and skin.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.

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

Hair follicles are valuable for regenerative medicine and wound healing.

Skin cells show flexibility in healing wounds and forming tumors, with potential for treating hair disorders and chronic ulcers.

Aging in hair follicle stem cells leads to hair graying, thinning, and loss.

Drosha and Dicer are essential for hair follicle health and preventing DNA damage in skin cells.

Wounds can regenerate hair in young mice, but this ability declines with age, offering insights for improving tissue regeneration in the elderly.

A WNT10A gene mutation leads to ectodermal dysplasia by disrupting cell growth and differentiation.

Understanding hair growth involves complex factors, and more research is needed to improve treatments for hair loss conditions.

Topical finasteride might be a good alternative for hair loss treatment with fewer side effects, but more research is needed.

Hair can regrow in large wounds through a process similar to how hair forms in embryos, and understanding this could lead to new treatments for hair loss or scarring.

Minoxidil and finasteride effectively treat hair loss.

PPARγ is essential for maintaining healthy skin, controlling inflammation, and ensuring proper skin barrier function.

Epidermal stem cells have various roles in skin beyond just maintenance, including forming specialized structures and aiding in skin repair and regeneration.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

Krt15+ cells in the mouse intestine resist radiation and can start tumors.

Using human fat tissue derived stem cells in micrografts can safely and effectively increase hair density in people with hair loss.

Different genes are active in dogs' hair growth and skin, similar to humans, which helps understand dog skin and hair diseases and can relate to human conditions.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

A specific group of slow-growing stem cells marked by Thy1 is crucial for skin maintenance and healing in mice.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

The study showed that hair follicle stem cells can maintain and organize themselves in a lab setting, keeping their ability to renew and form hair and skin.

Quercetin significantly helps hair growth by activating hair follicles and improving blood vessel formation around them.

Different types of skin cells play specific roles in development, healing, and cancer.

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

The research found a way to identify and study skin cells with stem cell traits, revealing they behave differently in culture and questioning current stemness assessment methods.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.
