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.

Different hair types in mammals are linked to variations in specific protein genes, with changes influenced by their living environments.

DNA changes in tetraploid wheat improve root growth and nitrogen use.

The study mapped yak skin cells to understand hair growth better.

Environmental factors can cause mutations in skin proteins, leading to skin disorders.

Targeting specific genes in certain pathways may help treat male pattern baldness.

Key genes and pathways involved in thyroid eye disease were identified, aiding potential treatment and diagnosis.

PPARγ is essential for maintaining healthy skin, controlling inflammation, and ensuring proper skin barrier function.

Prdm1 is necessary for early whisker development in mice but not for other hair, and its absence changes nerve and brain patterns related to whiskers.

Long-term use of finasteride in women can cause hormonal changes, DNA damage, and menstrual issues.

MicroRNAs are crucial in controlling cell signaling, affecting cancer and tissue regeneration.

Found key genes affecting hair loss, immune response, and skin development; more research needed for better treatments.

Human beard hair medulla contains a unique and complex mix of keratins not found in other human tissues.

Hoxc genes control hair growth through Wnt signaling.

UV photography can help identify people at higher risk for skin cancer, and male pattern baldness at age 45 is linked to a higher risk of certain skin cancers.

Male pattern baldness is linked to a higher risk of certain skin cancers, especially on the scalp.

Different cells affect hair follicle blood vessels, endothelial cells react differently to inflammation and oxidized fats, and prasugrel better protects heart vessels during a procedure than clopidogrel.

Prasugrel is better than clopidogrel at preventing heart damage and improving blood flow in small heart vessels during heart artery procedures.

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

Keratins are important for skin cell health and their problems can cause diseases.

K16 can partially replace K14 but causes hair loss and skin issues.

Cysteine-rich keratins evolved independently in mammals, reptiles, and birds for hard skin structures like hair, claws, and feathers.

The research identified two types of keratinocytes in chicken scales: one for hard scales and another for soft skin, with similarities to human skin differentiation.

Hair papilla cells are crucial for blood vessel development in hair follicles, affecting hair growth and loss.

Ovol2 is crucial for hair growth and skin healing by controlling cell movement and growth.

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

The 190-kbp domain contains all human type I hair keratin genes, showing their organization and evolution.

Skin bacteria, specifically Staphylococcus aureus, help in wound healing and hair growth by using IL-1β signaling. Using antibiotics on skin wounds can slow down this natural healing process.

Genetic variations affecting skin structure play a key role in severe acne.

The skin's basement membrane has specialized structures and molecules for different tissue interactions, important for hair growth and attachment.
