Red blood cell folate levels are reliable indicators of long-term folate status in alopecia areata patients.

Human skin has multiple layers and functions, with key roles in protection, temperature control, and appearance.

Hormones affect skin aging, and treatments targeting hormonal balance may improve skin health.

PRP shows promise for improving healing and hair growth in cosmetic surgery but results can vary.

PCOS is a complex condition with major health impacts, needing more research for better diagnosis and treatment.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

The document concludes that skin stem cells are important for hair growth and wound healing, and could be used in regenerative medicine.

Stress can worsen skin and hair conditions by affecting the skin's immune response and hormone levels.

The conclusion is that certain cell interactions and signals are crucial for hair growth and regeneration.

Hair color production in mice is closely linked to the hair growth phase and may also influence hair growth itself.

Vitamin D and its receptor regulate skin functions like cell growth, immunity, hair cycle, and tumor prevention.

Androgens can cause hair growth in some areas and hair loss on the scalp.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

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.

K_ATP channel gene mutations are linked to heart diseases, but more research is needed to understand the connection and treatment potential.

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.

Vitamin D has potential benefits for cancer prevention, heart health, diabetes, obesity, muscle function, skin health, and immune function, but clinical results are mixed and more research is needed.

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.

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

A mother's PPARγ is crucial for preventing harmful milk that can cause inflammation and growth problems in babies.

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.

NF-κB is crucial for zebrafish heart repair, affecting heart cell growth and repair processes.

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

Sphynx cats are hairless and Devon Rex cats have curly hair due to specific genetic mutations.

Hair grays due to oxidative stress and fewer functioning melanocytes.

Progress has been made in skin and nerve regeneration, but more research is needed to improve methods and ensure safety.

Blocking IL-12/IL-23p40 helped reverse severe hair loss in patients.

Advanced nanocarrier and microneedle drug delivery methods are more effective, safer, and less invasive for treating skin diseases.

Hirsutism is a strong sign of high male hormones and metabolic problems in women with PCOS, but acne and hair loss are not.

Different scaffold patterns improve wound healing and immune response in mouse skin, with aligned patterns being particularly effective.
