Stem cells help repair tissue mainly by releasing beneficial substances, not by replacing damaged cells.

Finasteride increases hair density in female androgenetic alopecia, but individual results may vary.

Hair loss in balding individuals is linked to changes in specific hair growth-related genes.

Nanog gene boosts stem cells, helps hair growth, and may treat hair loss.

New hair loss treatments may include topical medications, injections, and improved transplant methods.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Melanocytes produce melanin; their defects cause vitiligo and hair graying, with treatments available for vitiligo.

Exosomes can help repair and heal tissues, improving health and vitality.

Patients with Discoid Lupus Erythematosus have lower vitamin D and antioxidant levels and higher oxidative stress.

Foxp3+ Regulatory T Cells are important for immunity and tolerance, affect hair growth and wound healing, and their dysfunction can contribute to obesity-related diseases and other health issues.

TLR2 helps control hair growth and regeneration, and its reduction with age or obesity can impair hair growth.

Adipose-derived stem cells may help with hair loss, but more research is needed.

Older mice have stiffer skin with less elasticity due to changes in collagen and skin structure, affecting aging and hair loss.

HA-stimulated stem cell vesicles improved hair growth in male mice with androgenetic alopecia.

Using three different drugs together may better treat eye diseases like glaucoma and macular degeneration.

Nanomaterials can significantly improve wound healing and future treatments may include smart, real-time monitoring.

Nanomaterials show promise in improving wound healing but require more research on their potential toxicity.

Microneedle technology has advanced for painless drug delivery and sensitive detection but faces a gap between experimental use and clinical needs.

Auto-antibody testing is a useful but not definitive tool in diagnosing interstitial lung diseases, and using a specific algorithm could make testing more cost-effective.

New treatments like nanotechnology show promise in improving skin cancer therapy.

Using protein degradation to fight cancer drug resistance shows promise but needs more precise targeting and fewer side effects.

Radiation therapy damages skin structure and immune function, causing inflammation and potential hair loss.

Gamma delta T cells in the skin help with healing and defense but can also cause autoimmune issues, and more research is needed to understand how they are activated.

Human prenatal skin develops an immune network early on that helps with skin formation and healing without scarring.

Calcium signals and SHH guide the direction of feather growth in chicken skin.

Dengue virus can infect human hair follicle cells and may cause hair loss.

Animal models have helped understand hair loss from alopecia areata and find new treatments.

Treatments that reduce oxidative stress and fix mitochondrial problems may help heal chronic wounds.

Activating Nrf2 in skin cells speeds up wound healing by increasing the growth of certain stem cells.

Eating grape powder may reduce the severity of skin allergy symptoms.
