TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

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.

Stress can stop hair growth in mice, and treatments can reverse this effect.

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

Animals that change color with the seasons mainly do so in response to daylight changes, but climate change is causing camouflage problems that may require evolutionary changes.

Stress increases a factor in mice that leads to hair loss, and blocking this factor may prevent it.

New treatments for Alopecia Areata show promise but need to be more effective and affordable.

Hair elemental analysis could be useful for health and exposure assessment but requires more standardization and research.

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.

Phospholipase A2 is necessary for the correct placement of PIN proteins in plant roots, affecting root growth.

New methods have greatly improved our understanding of stem cell behavior and roles in the body.

Muscles and nerves that cause goosebumps also help control hair growth.

Environmental factors, hormones, nutrition, and stress all significantly affect skin health and aging.

Mutations in Gasdermin A3 cause skin inflammation and hair loss by disrupting mitochondria.

Hair grays due to oxidative stress and fewer functioning melanocytes.

Restoring mitochondrial function in mice reversed their skin wrinkling and hair loss.

Wnt signaling is crucial for skin and hair development and its disruption can cause skin tumors.

Keratin proteins are crucial for healthy skin, but mutations can cause skin disorders with no effective treatments yet.

Some Thai plants, especially Carthamus tinctorius, could help prevent hair loss and promote hair growth without adverse effects.

Msx2 and Foxn1 are both crucial for hair growth and health.

Korean Red Ginseng has beneficial components that help with stress, immunity, fatigue, memory, blood flow, and disease protection.

Androgens cause skin issues like acne and hair growth in women, often due to PCOS, and can be treated with medication and lifestyle changes.

The gene Foxq1, controlled by Hoxc13, is crucial for hair follicle differentiation.

Cancer development is like natural selection, involving mutated cells and environmental factors.

Technique creates 3D cell spheroids for hair-follicle regeneration.

Low iron and vitamin D levels are linked to hair loss in women.

There are still challenges in diagnosing and treating chronic skin diseases, but there is hope for future improvements.

Key genes are crucial for Drosophila wing development and could be insecticide targets.

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

Cancer treatments often cause hair disorders, significantly affecting patients' quality of life, and better management methods are needed.
