Microneedles improve drug delivery in various body parts, are safe and painless, and show promise in cosmetology, vaccination, insulin delivery, and other medical applications.

Transplant success has improved with better immunosuppressive drugs and donor matching.

Periodontal ligament stem cells show promise for regrowing tissues but require more research for safe, effective use.

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

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

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

Nanoparticles can improve skin drug delivery but have challenges like toxicity and stability that need more research.

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.

PEVs improve minoxidil skin penetration, increasing hair growth.

Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.

Foxp3 is crucial for regulatory T cell function, and targeting these cells may help treat immune disorders.

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

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

TRP channels in the skin are important for sensation and health, and targeting them could help treat skin disorders.

Hibiscus plant extracts may have health benefits like lowering blood pressure and protecting the heart.

Asia has made significant progress in tissue engineering and regenerative medicine, but wider clinical use requires more development.

Rhodococcus equi causes severe pneumonia in young foals, and effective vaccines are needed due to foals' weak immune responses.

Minoxidil effectively treats hair loss, but use cautiously and monitor side effects.

The research identified various cell types in mouse and human teeth, which could help in developing dental regenerative treatments.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

Liposomes could improve how skin care products work but are costly and not very stable.

Melatonin helps regulate hair growth and protects the hair follicle from stress.

We need more research to better understand human hair follicle stem cells for improved treatments for hair loss and skin cancer.

UV radiation can help sterilize wounds and promote healing but requires careful use to avoid damaging cells.

Skin-derived precursors in hair follicles come from different origins but function similarly.

Skin surface lipids are important for skin health and altering them could help prevent aging and treat skin conditions.

FGF signaling is a promising target for developing treatments for wounds, metabolic diseases, and cancer.

Restoring hair bulb immune privilege is crucial for managing alopecia areata.

One minoxidil-sensitive potassium channel exists in human hair follicles.

Fullerenes show potential in skin care but need more safety research.
