Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.

The enzyme 17β-HSD type 2 mainly performs oxidation in human sebaceous glands, which may help protect against acne.

Scientists found cells in hair that are key for growth and color.

Hair growth is influenced by various body and external factors, and neighboring hairs communicate to synchronize regeneration.

FA2H is essential for normal fur and sebum production in mice.

The hair follicle infundibulum plays a key role in skin health and disease, and understanding it better could lead to new skin disease treatments.

The study found that a specific area of the hair follicle helps start hair growth by reducing the blocking effects on certain cells and controlling growth signals.

Radiation mainly affects keratinocyte stem cells, not melanocyte stem cells, causing hair to gray.

Loss of Fz6 disrupts hair follicle and associated structures' orientation.

Some stem cells in the body rarely divide, which could help create better treatments for diseases and aging.

The document concludes that careful design of genetic fate mapping experiments is crucial for accurate cell lineage tracing in mice.

Gene therapy, especially using atoh1, shows promise for creating functional sensory hair cells in the inner ear, but dosing and side effects need to be managed for clinical application.

The environment around melanocyte stem cells is key for hair regeneration and color, with certain injuries affecting hair color and potential treatments for pigmentation disorders.

Researchers found an RNA transcript that might help control a growth factor linked to tumor development.

NF-κB is crucial for different stages and types of hair growth in mice.

Double-stranded RNA causes inflammation in hair follicle cells, which may help understand and treat alopecia areata.

Stem cell differentiation is crucial for skin barrier maintenance and its disruption can lead to skin diseases.

Lack or blocking of SRD5a, a key component in hormone creation, can lead to conditions like pseudohermaphrodism and affect hair growth, bone mass, muscle strength, and reproductive health. More research is needed on its regulation from fertilization to adulthood.

Researchers identified specific genes that are important for mouse skin cell development and healing.

The gene Msx2 is crucial for hair follicle regeneration during wound healing.

Melanoblasts migrate to the skin using various pathways, and understanding this process could help with skin disease research.

A special environment is needed to fully activate sleeping stem cells.

Using polyethylenimine-DNA to deliver the hTERT gene can stimulate hair growth and may be useful in treating hair loss, but there could be potential cancer risks.

Scientists have made progress in understanding hair follicle stem cells, identifying specific genes and markers, and suggesting their use in treating hair and skin conditions.

A yeast-based test can detect the steroid methyltestosterone in urine longer than traditional methods.

Deleting the Far2 gene in mice causes sebaceous gland issues and patchy hair loss.

The conclusion is that teeth, hair, and claws have similar stem cell niches, which are important for growth and repair, and more research is needed on their regulation and potential markers.
