Smad1 and Smad5 are essential for hair follicle development and stem cell sleepiness.

Acne keloidalis nuchae is a chronic skin condition more common in African men, causing itchy or painful bumps and can lead to permanent hair loss if not treated early.

Hidradenitis suppurativa is caused by genetic factors, inflammation, bacteria, hormones, and lifestyle factors like obesity and smoking.

Hair loss can indicate or worsen with systemic diseases, and treating the underlying condition is important.

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

Sebaceous glands can heal and regenerate after injury using their own stem cells and help from hair follicle cells.

Plet-1 protein helps hair follicle cells move and stick to tissues.

Activating Nrf2 in skin cells speeds up wound healing by increasing the growth of certain stem cells.

Sebaceous glands can help harvest hair follicle stem cells to regenerate skin and hair.

Androgenetic alopecia, or hair loss, is caused by a mix of genetics, hormones, and environment, where testosterone affects hair growth and causes hair to become smaller and grow for a shorter time.

The study concluded that immune cells attacking hair follicles cause hair loss in alopecia, with genetics and environment also playing a role, and highlighted the potential of certain treatments.

The human scalp hair bulb contains different types of melanocytes with varying abilities to produce melanin.

The document reports the first case of a rare skin condition in Colombia, the 19th case worldwide.

Hair growth and development are controlled by specific signaling pathways.

Innate immunity genes in hair follicle stem cells might have new roles beyond traditional immune functions.

LGR5 is a common marker of hair follicle stem cells in different animals and is important for hair growth and regeneration.

Imiquimod can cause rare skin side effects, some irreversible, and long-term follow-up is important for users.

Overexpression of sPLA2-IIA in mouse skin reduces hair stem cells and increases cell differentiation through JNK/c-Jun pathway activation.

Eruptive vellus hair cysts are often missed in diagnoses.

Epidermal stem cells help heal severe skin wounds and have potential for medical treatments.

Aging reduces skin stem cell function, leading to changes like hair loss and slower wound healing.

Nanotechnology could improve hair regrowth but faces challenges like complexity and safety concerns.

Genetic changes in mice help understand skin and hair disorders, aiding treatment development for acne and hair loss.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Early diagnosis and treatment of Hidradenitis Suppurativa are important to prevent serious physical and mental effects.

Some medications for inflammation can cause a condition with scalp rashes and hair loss, often linked to Crohn's disease, and may require treatment changes to prevent permanent hair loss.

Cell death shapes skin stem cell environments, affecting inflammation, repair, and cancer.

The document concludes that the immune-inhibitory environment of the hair follicle may prevent melanoma development.

Overexpression of HDGF in melanocytes does not cause cancer.

Certain immune system proteins are important for skin healing but can cause problems if there are too many of them.
