Chitosan nanofiber scaffolds improve skin healing and are promising for wound treatment.

Hormone therapy is essential for transgender individuals but requires careful management due to possible metabolic effects.

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.

4D polycarbonate scaffolds show promise for soft tissue repair due to their biocompatibility, shape memory, and minimal immune response.

Scientists created stem cells that can grow hair and skin.

Sericin hydrogels heal skin wounds well, regrowing hair and glands with less scarring.

Treatments for melanin disorders exist, but more effective options needed.

Hair follicle regeneration needs special conditions and young cells.

Oncogenic melanocyte stem cells can develop into melanoma similar to human cases.

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

Scientists found a way to grow human hair cells in a lab that can create new hair when transplanted.

Multiphoton microscopy is a promising tool for detailed skin imaging and could improve patient care if its challenges are addressed.

Hair follicle stem cells could help repair nerves and avoid ethical issues linked to embryonic stem cells.

The study found that bioengineered hair follicles work when using cells from the same species but have issues when combining human and mouse cells.

Modified rat stem cells on a special scaffold improved blood vessel formation and wound healing in skin substitutes.

Hair transplantation successfully treated a woman's hair loss caused by a tight ponytail.

3D-printed microneedles improve drug delivery by being precise, cost-effective, and less invasive.

Finasteride may affect fetal brain development and increase arousal, but more research is needed for safety confirmation.

Microneedles with enhancer effectively promote hair growth and increase hair density.

Testosterone can slow down hair growth when combined with certain cells from bald scalps, and this effect can be blocked by an androgen receptor blocker.

Prominin-1 expressing cells in the dermal papilla help regulate hair follicle size and communication but don't aid in skin repair.

5-alpha-reductase inhibitors may cause a low incidence of erectile dysfunction that decreases over time.

miR-22 helps skin cancer grow and spread by activating specific cell signals.

Gonadal hormones significantly affect the severity of alopecia areata in mice.

The 3D scaffold helped maintain hair cell traits and could improve hair loss treatments.

Finasteride given to baby rats causes anxiety-like behavior and worsens learning from punishment in adult rats.

The study found that Central Centrifugal Cicatricial Alopecia mainly affects middle-aged African descent women, is linked to certain hair care practices and genetics, and often goes undiagnosed for years.

Macrophage-stimulating protein helps hair grow and can start hair growth phase in mice and human hair samples.

Gilles de la Tourette syndrome is treatable, with behavioral therapy as a recommended first option and other treatments available for more severe cases.

Finasteride slows down motherly behavior in first-time pregnant rats.
