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

The S100A4 protein is more common in psoriatic skin and could be a target for treating psoriasis.

Understanding normal hair growth and loss in children is key to diagnosing and treating hair disorders.

Hair follicle dermal stem cells are key for regenerating parts of the hair follicle and determining hair type.

Mice with human skin protein K8 had more skin problems and cancer.

The proteins transthyretin and megalin are more present in the growth phase of hair, suggesting they might affect hair health and growth.

The document concludes that the effectiveness of platelet rich plasma in aesthetic surgery is unclear due to inconsistent reporting and lack of objective measures in studies.

Genes related to calcium signaling and lipid metabolism are important for curly hair in Mangalitza pigs.

miR-140-5p in certain cell vesicles helps hair growth by boosting cell proliferation.

Fetal skin cells from a cell bank heal wounds faster and with less scarring than adult cells.

COVID-19 might affect male fertility, but more research is needed to understand the full impact.

Some drugs may help treat both COVID-19 and radiation injury.

Genetically-altered adult stem cells can help in wound healing and are becoming crucial in regenerative medicine and drug design.

Activating a protein called β-catenin in adult skin can make it behave like young skin, potentially helping with skin aging and hair loss.

Intestinal intraepithelial lymphocytes are crucial for gut immunity and maintaining the mucosal barrier.

The pituitary gland functions normally even after losing most SOX2+ stem cells.

The document discusses various eye conditions and their treatments, including a rare eye cancer in a baby, vision loss from a cancer drug, cataracts from a baldness treatment, a rare skin disorder, and a specific type of eye disease diagnosed with a special imaging technique.

A boy with chromosome 13q deletion syndrome developed eye cancer, a woman with breast cancer lost vision due to a rare side-effect of her treatment, a man's vision worsened after using a hair loss drug, and two rare disorders were discussed. Optical Coherence Tomography is useful for diagnosing and monitoring these conditions.

The Hairless gene is crucial for healthy skin and hair growth.

Current therapies cannot fully regenerate adult skin without scars; more research is needed for scar-free healing.

Scalp skin grafts effectively cover lower limb defects with high success and minimal complications.

Fat tissue vesicles protect skin from UV damage better than stem cell vesicles.

Male pattern baldness may be caused by scalp pressure on hair follicles, which increases with age and leads to a cycle of hair loss. This process is not directly determined by genes.

3D bioprinting is useful for making tissues, testing drugs, and delivering drugs, but needs better materials, resolution, and scalability.

Wnt4 protein makes the outer skin layer thicker in burn wounds by turning on a specific healing pathway and loosening the connections between skin cells.

Researchers developed a 3D model of human hair follicle cells that can help understand hair growth and test new hair loss treatments.

The silk fibroin-based hydrogel shows promise for treating melanoma and healing infected wounds by killing tumor cells and bacteria, and supporting skin recovery.

The guidelines recommend informed consent for gender-affirming treatments and stress the importance of personalized, culturally sensitive care for transgender individuals.

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

Cancer can hijack the body's cell repair system to promote tumor growth, and targeting this process may improve cancer treatments.
