Meis2 is essential for touch sensation and proper nerve connection to touch receptors in certain skin areas of mice.

Researchers mapped and categorized specific keratin-associated protein genes on human chromosome 21q22.1.

Sostdc1 controls the size and number of hair and mammary gland structures.

A small group of slow-growing cells causes basal cell carcinoma to return after treatment.

Fingerprints form uniquely before birth due to specific genetic pathways and local signals.

The best method for urethral reconstruction is using hypoxia-preconditioned stem cells with autologous cells on a vascularized synthetic scaffold.

Elastic Net DNA methylation clocks are inaccurate for predicting age and health status; a "noise barometer" may better indicate aging and disease.

The technology can help diagnose and subtype autoimmune diseases by identifying specific autoantibodies.

Polyurethane dressings show promise for wound healing but need improvements to adapt better to the healing process.

A new mutation in the TMEM173 gene and a risk allele in IFIH1 cause a unique set of immune-related symptoms.

Zebrafish with mutations similar to human Cantú Syndrome have heart cells with altered channel properties, making them a good model to study the condition.

Notch-related genes play a key role in the development and cycling of hair follicles.

Activating Notch in adult skin causes T cells and neural crest cells to gather, leading to skin issues.

Yak belly hair has higher porosity and is less stiff than human hair, making it absorb dye better but less suitable as a direct substitute for hair dyeing.

Confocal Laser Scanning Microscopy (CLSM) is a useful tool for studying how drugs interact with skin and diagnosing skin disorders, despite some limitations.

Photodynamic therapy can remove nonpigmented hair in mice and might work for humans.

Stress increases a factor in mice that leads to hair loss, and blocking this factor may prevent it.

A teenage girl with high androgen levels and PCOS developed a rare liver tumor, suggesting a possible link between high androgens and the tumor's growth.

The silk fibroin hydrogel with FGF-2-liposome can potentially treat hair loss in mice.

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

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.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Activating Nrf2 protects human hair follicles from oxidative stress and helps prevent hair growth inhibition.

Activating β-catenin in mammary cells leads to changes that cause early-stage abnormal growths similar to skin structures.

Blocking both main energy pathways can stop hair follicle stem cell-induced skin cancer growth.

Minoxidil boosts hair growth by targeting adenosine and possibly sulfonylurea receptor 2B.

Valproic acid may help hair grow and could be a safe treatment for hair loss.

Placental growth factor may help treat hair loss.

Older people's sweat glands are less effective at helping skin wounds heal due to weaker cell connections.

Calcium microcapsules are better for long-term use in artificial dermal papilla, while barium microcapsules are good for short-term.
