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

Macrophages help heal nerves by aiding the maturation of Schwann cells and are important for nerve 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 skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

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

The hydrogel with a 1:3 ratio of hydroxyethyl cellulose to hyaluronic acid is effective for delivering drugs through the skin to treat acne.

Adult female acne treatment should be personalized, considering individual preferences and pregnancy, using various topical and oral medications while managing side effects and resistance.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

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.

Folliculitis decalvans is a rare scalp condition causing scarring hair loss, treated with long-term antibiotics and other medications, but it often comes back and is hard to manage.

Psoriasis skin changes are complex and might need several biopsies for a clear diagnosis.

Understanding the mouse hair cycle is crucial for cancer research.

Choosing the right model order in brain connectivity analysis can affect the detection of differences between healthy individuals and those with seasonal affective disorder.

Fetal wound healing changes with development, affecting inflammation and collagen, which may influence scarring.

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

Skin-derived precursors in hair follicles come from different origins but function similarly.

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

A genetic region near the PAX1 gene is linked to a higher risk of scoliosis in females.

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

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

Researchers identified genes linked to coat color, body size, cashmere production, and high altitude adaptation in goats.

A new mutation in the human glucocorticoid receptor reduces its function and causes resistance to glucocorticoids.

Targeted cancer therapies often cause skin reactions, so dermatologists must manage these effects.

BMP2 and BMP7 have opposite roles in feather formation.

The study found that diseases can be grouped by symptoms and that the accuracy of predicting disease-related genes varies with the data source.

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

Sponge helps heal wounds faster with less inflammation and better skin/hair growth.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

Skin has specialized touch receptors that can tell different sensations apart.

Hair shedding is an active process that could be targeted to treat hair loss.
