Higher doses of cranial irradiation are linked to permanent hair loss.

The study found that hair follicles are above muscle connections in the scalp, which may help protect stem cell areas.

Male pattern baldness involves hormone-related hair thinning, shorter hair, and inflammation.

Skin's uneven surface and hair follicles affect its stress and strain but don't change its overall strength, and help prevent the skin from peeling apart.

Some drugs can cause hair loss, and stopping these drugs often leads to hair regrowth.

Removing centrosomes from skin cells leads to thinner skin and stops hair growth, but does not greatly affect skin cell differentiation.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

The paper concludes that understanding melanocyte development can help in insights into skin diseases and melanoma diversity.

Poliosis circumscripta is a patch of white hair caused by lack of melanin, linked to genetic and acquired conditions.

Melatonin affects skin cell growth differently based on how much and how long it's used.

Glycine reduces skin pigmentation by lowering melanin production.

A benign tumor developed at a girl's BCG vaccination site, not previously linked to the vaccine.

Burn scars heal abnormally and more research is needed to find better treatments.

SOX9 helps determine stem cell roles by interacting with DNA and proteins that control gene activity.

Lgr5 is a marker for active, self-renewing stem cells in the intestine and skin, important for tissue maintenance.

Different types of fibroblasts play various roles in diseases and healing, and more research on them could improve treatments.

Melatonin may benefit skin health and could be a promising treatment in dermatology.

Inactive stem cells in hair follicles and muscles can avoid detection by the immune system.

Telocytes might help with skin repair and regeneration.

Aging causes skin stem cells to work less effectively.

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

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.

The document concludes that adult mammalian skin contains multiple stem cell populations with specific markers, important for understanding skin regeneration and related conditions.

The circadian clock influences the behavior and regeneration of stem cells in the body.

Stress can worsen skin conditions by affecting hormone levels and immune response.

Different scaffold patterns improve wound healing and immune response in mouse skin, with aligned patterns being particularly effective.

Melanocyte development from neural crest cells is complex and influenced by many factors, and better understanding could help treat skin disorders.

Platelet preparations generally show positive effects on wound healing and facial rejuvenation, but more thorough research is needed to confirm their effectiveness.

Nanoparticles can enter the skin, potentially causing toxicity, especially in damaged skin.

PPAR agonists show promise for skin conditions but need more research before being a main treatment.
