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.

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Foxp3 is crucial for regulatory T cell function, and targeting these cells may help treat immune disorders.

Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.

Janus kinase inhibitors are promising treatments for autoimmune skin diseases like eczema and psoriasis.

Fat cells in the skin help start healing and form important repair cells after injury.

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

MicroRNA-302 helps improve the conversion of body cells into stem cells by blocking NR2F2.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

Cytokeratin 19 and cytokeratin 15 are key markers for monitoring the quality and self-renewing potential of engineered skin.

Platelet-rich plasma might help with hair growth and skin conditions, but more research is needed to prove its effectiveness and safety.

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

Platelet-rich plasma may help with hair growth and skin quality but more research is needed to confirm its effectiveness.

New compounds were made that block an enzyme linked to breast cancer better than existing treatments.

PRP injections improve hair thickness for baldness.

Correct skin biopsy techniques are crucial to avoid misdiagnosis of skin diseases.

PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.

New single-cell analysis techniques are improving our understanding of stem cells and could help in treating diseases.

Formyl-peptide receptor agonists could be new anti-inflammatory drugs.

Olive oil compounds may help prevent cancer in animals, but human results are mixed.

MicroRNA-214 is important for skin and hair growth because it affects the Wnt pathway.

Restoring hair bulb immune privilege is crucial for managing alopecia areata.

Male hormones and their receptors play a key role in hair loss and skin health, with potential new treatments being explored.

Removing both Atr and Trp53 genes in adult mice causes severe tissue damage and death due to DNA damage.

Scientists created stem cells that can grow hair and skin.

No treatment fully prevents hair loss from chemotherapy yet.

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

Grafted rodent and human cells can regenerate hair follicles, but efficiency decreases with age.

The p75 neurotrophin receptor is important for hair follicle regression by controlling cell death.
