The PDGF/PDGFR pathway is a potential drug target with mixed success in treating various diseases, including some cancers and fibrosis.

Alopecia areata involves immune activation in the scalp, suggesting treatments targeting TH1, TH2, and IL-23 pathways.

Different types of skin cells have unique genetic markers that affect how likely they are to spread cancer.

Some medicinal plants can help heal wounds and may lead to new treatments.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Stress-related substance P may lead to hair loss and negatively affect hair growth.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Male and female skin differ due to hormones, affecting conditions like hair loss, acne, and skin cancer, and suggesting a need for gender-specific treatments.

Peptide hydrogels heal burn wounds faster and better than standard dressings.

Estrogen therapy can reduce skin aging but has cancer risks.

The document concludes that more research is needed to better understand and treat primary cicatricial alopecias, and suggests a possible reclassification based on molecular pathways.

Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.

Targeting the IL-23/IL-17 pathway effectively treats several inflammatory skin diseases.

Alopecia areata is a common autoimmune disease affecting about 2% of people, causing significant disability and often associated with mental health issues and other autoimmune conditions.

The document concludes that a better understanding of cell changes during wound healing could improve treatments for chronic wounds and other conditions.

Eating less sugar, milk, and saturated fats and more vegetables and fish may help treat and prevent acne.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

Adam10 enzyme is crucial for healthy skin and proper Notch signaling.

Low oxygen conditions increase the hair-growing effects of substances from fat-derived stem cells by boosting growth factor release.

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.

Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.

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

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

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

Targeting androgen receptors could be a promising way to treat skin disorders with fewer side effects.

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

Hair follicles produce and respond to melatonin, affecting hair growth and sensitivity to estrogen.

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

Understanding how cells die in the skin is important for treating skin diseases and preventing hair loss.

Estrogens help reduce skin aging, and SERMs might offer similar benefits without the risks of hormone therapy.
