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

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

The document concludes that specific cells are essential for hair growth and more research is needed to understand how to maintain their hair-inducing properties.

The conclusion is that PCOS is caused by ovarian sensitivity to hormones and disrupted hormone control, possibly due to ovarian factors, and more research is needed.

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

Macrophages help heal nerves by aiding the maturation of Schwann cells and are important for nerve repair.

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.

Finasteride helps increase hair growth in men with hair loss.

Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.

Hair analysis can detect cocaine use but doesn't accurately show the amount or timing of use.

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

Stress can stop hair growth in mice, and treatments can reverse this effect.

Normal skin cell renewal doesn't need RAR signaling, but vitamin A-related skin thickening does.

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

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

Men's sensitivity to male hormones might affect how severe COVID-19 gets for them.

MicroRNA-302 helps improve the conversion of body cells into stem cells by blocking NR2F2.

Hair follicles produce and respond to melatonin, affecting hair growth and sensitivity to estrogen.

Eclipta alba extract may help hair grow similarly to Minoxidil.

Minoxidil can help grow hair in mice by making cells grow and improving hair quality. More research needed.

Understanding how cells die in the skin is important for treating skin diseases and preventing hair loss.

Cytokeratin 19 and cytokeratin 15 are key markers for monitoring the quality and self-renewing potential of engineered skin.

Estrogens help reduce skin aging, and SERMs might offer similar benefits without the risks of hormone therapy.

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

Platelet-rich plasma might help with hair growth and skin conditions, but more research is needed to prove its effectiveness and safety.

The AUTS2 gene is linked to neurological disorders and may affect human brain development and cognition.

Hormones, especially androgens, play a big role in acne, but most acne sufferers don't have a hormone disorder. Hormonal treatments, including birth control pills, can be very effective for women whose acne doesn't improve with regular treatments.

Finasteride and minoxidil are effective for hair regrowth, while treatments for alopecia areata have varying success and continuous treatment is necessary.

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

Stress increases nerve fibers and immune cell activity in mouse skin, possibly worsening skin conditions.
