Adult stem cells from rat whisker follicles can regenerate hair follicles and sebaceous glands.

Neuregulin3 affects cell development in the skin and mammary glands.

Male hormones are important for hair and oil gland development and can cause conditions like excessive hair growth and acne.

Testosterone and some of its forms can strongly stimulate oil gland growth in skin.

Androgens cause oil-producing skin cells with androgen receptors to mature and produce more oil.

Dyes can penetrate human skin and hair follicles up to 1.2 mm deep and the sebaceous gland can store dye; Indocyanine Green lotion was made for safe dyeing and monitoring.

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.

Scientists created a long-lasting stem cell line from human hair that can turn into different skin and hair cell types.

Researchers found a gene in hamsters that responds to male hormones and may be indirectly controlled by them.

Acne is a common skin condition linked to diet, hormones, and genetics, and early treatment can prevent scarring.

Scalp psoriasis can cause different types of hair loss, with some patients developing permanent hair loss, and treatment may be stopped due to skin reactions.

The document concludes that skin stem cells are important for hair growth and wound healing, and could be used in regenerative medicine.

Insulin resistance and obesity are key factors in the development and worsening of polycystic ovary syndrome, and lifestyle changes are important for managing it.

The absence of functional sebaceous glands causes hair follicle destruction and scarring alopecia.

Isotretinoin is highly effective in treating severe acne, rosacea, and gram-negative folliculitis.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

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.

The document concludes that more research is needed to better understand and treat primary cicatricial alopecias, and suggests a possible reclassification based on molecular pathways.

Vitamin D is important for skin health and may affect conditions like psoriasis and hair loss, but more research is needed to understand its role fully.

Pregnancy can cause skin pigmentation, stretch marks, and changes in hair, nails, and sweat glands, with most resolving after birth.

The document concludes that accurate diagnosis of different types of hair loss requires careful examination of hair and scalp tissue, considering both clinical and microscopic features.

Mutant mice help researchers understand hair growth and related genetic factors.

Hormones, especially androgens, play a key role in acne, which can be a symptom of systemic diseases like PCOS and may require targeted treatment.

Progress has been made in skin and nerve regeneration, but more research is needed to improve methods and ensure safety.

Acne is a chronic disease linked to various systemic conditions and has significant psychological and social effects.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

C/EBPalpha and C/EBPbeta are crucial for normal skin and oil gland cell development in adult mice.

The protein SLC1A3 is important for activating skin stem cells and is necessary for normal hair and skin growth in mice.

Acne is significantly influenced by genetics, and understanding its genetic basis could lead to better, targeted treatments.

The review found that different stem cell types in the skin are crucial for repair and could help treat skin diseases and cancer.
