Facial feminization surgery is effective in helping transgender women appear more feminine and has high patient satisfaction.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

Modulating BMP activity changes the number, size, shape, and type of ectodermal organs.

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.

Animals that change color with the seasons mainly do so in response to daylight changes, but climate change is causing camouflage problems that may require evolutionary changes.

Overexpressing Dsg3 in mice skin causes excessive cell growth and abnormal skin development.

Scientists created stem cells that can grow hair and skin.

Prolactin affects hair growth and skin conditions, and could be a target for new skin disease treatments.

No treatment fully prevents hair loss from chemotherapy yet.

Grafted rodent and human cells can regenerate hair follicles, but efficiency decreases with age.

New hormonal contraceptives are safer, have fewer side effects, and offer health benefits for women.

Women with PCOS may take longer to get pregnant but can have a normal family size, and should manage their overall health to reduce long-term health risks.

Gynecologists should provide comprehensive care for transgender patients, including mental health evaluation, hormone therapy, and surgical options, while monitoring for side effects and ensuring patient safety.

The document concludes that cosmetic surgery is still mainly a practice for women and the gender gap in this field is expected to continue.

The conclusion is that managing androgen excess requires long-term treatment, including hormonal contraceptives and androgen blockers, with follow-up after six months.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

New treatments for male hypogonadism are effective and should be personalized.

Muscles and nerves that cause goosebumps also help control hair growth.

5α-reductase inhibitors can cause sexual problems, higher risk of aggressive prostate cancer, and depression.

The conclusion is that hair growth can be improved by activating hair cycles, changing the surrounding environment, healing wounds to create new hair follicles, and using stem cell technology.

Human hair follicle stem cells can turn into multiple cell types but lose some of this ability after being grown in the lab for a long time.

Understanding how fetal wounds heal could help improve healing in adults.

New LPA receptors (LPA4, LPA5, LPA6) have diverse roles in the body.

Oestrogens help maintain healthy skin, heal wounds, and may protect against skin aging and cancer.

Advanced nanocarrier and microneedle drug delivery methods are more effective, safer, and less invasive for treating skin diseases.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Wnt1a-conditioned medium from stem cells helps activate cells important for hair growth and can promote hair regrowth.

Using CRISPR for gene editing in the body is promising but needs better delivery methods to be more efficient and specific.

Certain signals and genes play a key role in hair growth and regeneration, and understanding these could lead to new treatments for skin regeneration.

Products should be called 'sperm-safe' only after thorough, well-designed tests.
