Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.

Epidermal stem cells are diverse and vary in activity, playing key roles in skin maintenance and repair.

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.

The document concludes that certain genetic mutations and dietary factors are involved in acne development, and treatments like isotretinoin and diet changes can help manage it.

Hormonal treatments, including birth control and antiandrogens, can effectively treat acne in women.

The document concludes that hirsutism is the main sign for diagnosing hyperandrogenism, which requires a detailed patient history and physical exam.

Hormonal treatments can help with acne but are not the first choice due to side effects and the need for careful patient selection.

Targeting the skin's endocannabinoid system could help treat skin disorders.

Nuclear hormone receptors play a significant role in skin wound healing and could lead to better treatment methods.

Acne is caused by genetics, diet, hormones, and bacteria, with treatments not yet curative.

Epidermal stem cells could lead to new treatments for skin and hair disorders.

BLIMP1 is essential for skin maintenance but not for defining sebaceous gland progenitors.

Cytokines and neuropeptides are key in controlling androgen levels, affecting skin and hair conditions.

Hormonal treatments are effective for severe or persistent acne and should be used with other acne therapies, considering potential side effects.

The conclusion is that a new biopsy technique and humidity chamber help study skin mites better and suggest mite overpopulation may cause skin diseases.

FA2H is essential for normal fur and sebum production in mice.

An extract from Quercus acutissima bark was found to reduce sebum production and block an enzyme linked to acne.

Photodynamic Therapy is an effective treatment for mild to severe acne.

Smad4 is important for healthy hair follicles because it helps produce a protein needed for hair to stick together and grow.

Hormonal contraceptives can help treat acne by affecting sebum production and androgen levels.

Local skin glucocorticoid production is crucial for healthy skin, and its disruption can lead to skin diseases.

Sebaceous glands in our skin, developing during pregnancy and active in puberty, produce sebum for skin lubrication, temperature control, and fighting germs, also help in hormone regulation, and their dysfunction can cause conditions like acne and hair loss.

A new non-invasive method can analyze skin mRNA to understand skin diseases better.

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

Lower irisin levels in the blood may indicate more severe acne.

Male pattern baldness may be caused by factors like poor blood circulation, scalp tension, stress, and hormonal imbalances, but the exact causes are still unclear.

The Hairless gene is crucial for hair cell development, affecting whether skin cells become hair or skin and oil gland cells.

High proliferative activity and peripheral invasion indicate malignancy in canine sebaceous gland tumors; the term 'epithelioma' should be updated for clarity.

Nanoparticles can be used to deliver drugs to hair follicles, potentially improving treatments for conditions like acne and alopecia, and could also be used for vaccine delivery and gene therapy.

The conclusion is that analyzing RNA from skin oils is a promising way to understand skin diseases.
