Wound healing involves three phases and various cells and factors, with scars typically forming in adults. Chronic wounds can occur due to various issues, and abnormal scarring can lead to hypertrophic or keloid scars. Emerging research areas include the role of proteins, microRNAs, macrophage manipulation, and stem cell treatment.

The OVOL1-OVOL2 axis is important for hair follicle differentiation and can help diagnose certain hair-related tumors.

Genetic defects and UV radiation cause skin damage and aging.

Green tea's EGCG has various health benefits, including antioxidant properties, skin protection, cancer cell growth inhibition, anti-inflammatory effects, fat breakdown, detoxification, diabetes management, hair growth stimulation, and prevention of gum disease.

Korean Red Ginseng may help prevent hair loss from chemotherapy.

Reflectance confocal microscopy can noninvasively diagnose onychomatricoma by showing unique features different from healthy nails or nail fungus.

Polyomavirus A2 infection in newborn mice caused hair follicle tumors.

Mf-rich hair degrades more than Ma-rich hair, especially with Proteinase K.

Hair coloring and bleaching can permanently break down hair protein and temporarily change its properties.

Some treatments work better for different types of hair loss, and nutrients like iron and L-lysine are important for preventing hair loss.

Hair follicles can regenerate after radiation damage but not during a specific growth phase.

Changing the environment around stem cells could help tissue repair, but it's hard to be precise and avoid side effects.

Rosacea is a skin condition with unclear causes, classified into four subtypes.

Calreticulin has roles in healing, immune response, and disease beyond its known functions in the endoplasmic reticulum.

New nanofiber technology improves wound healing by supporting cell growth and delivering treatments directly to the wound.

Fat cells help recruit healing cells and build skin structure during wound healing.

Chemotherapy causes hair loss by damaging hair follicles and stem cells, with more research needed for prevention and treatment.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

Myc activation reduces skin stem cells by affecting cell adhesion.

Fibromodulin might help reduce scarring if increased in adult wounds like in fetal skin that heals without scars.

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

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

A reliable system was developed to distinguish hair growth stages, aiding in identifying hair growth promoters or inhibitors.

The document concludes that specific cells are essential for hair growth and more research is needed to understand how to maintain their hair-inducing properties.

Estrogen Receptor ß (ERß) is the main hormone controller in human skin and hair follicles, not Estrogen Receptor α (ERα) or the Androgen Receptor (AR).

Fibroblast state switching is crucial for skin healing and development.

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

The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.

Scarless healing is complex and influenced by genetics and environment, while better understanding could improve scar treatment.

Nanotechnology shows promise for better chronic wound healing but needs more research.
