Human dermal fibroblasts are the main cells targeted by a virus that can cause a deadly skin cancer, and a certain inhibitor can effectively block this infection.

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.

Skin grafts on mice can cause an immune response leading to hair loss, useful for studying human hair loss conditions.

Tofacitinib may help treat severe hair loss, but more research is needed.

The conclusion is that Treg-targeted therapies have potential, but more knowledge of Treg biology is needed for effective treatments, including for cancer.

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.

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

Probiotic bacteria improved skin and hair health in aged mice.

Low doses of some substances can be beneficial, while high doses can be harmful or toxic.

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

Foxp3 is crucial for regulatory T cell function, and targeting these cells may help treat immune disorders.

Finasteride effectively treats baldness but may cause sexual side effects.

Testosterone's muscle-building effects do not require its conversion to DHT.

Polycystic Ovary Syndrome likely starts in childhood and may be genetic and influenced by early hormone exposure.

Different PIN proteins affect plant root hair growth by changing how auxin is transported.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

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

Potassium channel openers could help treat cardiovascular diseases and asthma but require better targeting to specific tissues for effective use.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

The article concludes that the wool follicle is a valuable model for studying tissue interactions and has potential for genetic improvements in wool production.

The research identified various cell types in mouse and human teeth, which could help in developing dental regenerative treatments.

Children with atopic dermatitis often have sleep problems, affecting their growth and behavior.

Thyroid hormones help hair grow, reduce hair loss, and increase hair pigment.

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

Smoking harms the skin, causing early aging and increasing cancer risk, but stopping smoking can improve skin health.

Men, especially older ones with health issues like prostate cancer, may have worse COVID-19 outcomes and could benefit from therapies targeting male hormones.

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.

Lignans and neolignans from plants may help protect against various health issues, including cancer and heart disease.

Minoxidil is the only FDA-approved topical drug for treating male or female pattern hair loss, and other medications like finasteride and dutasteride can also increase hair growth.

Dihydrotestosterone gel improved well-being and sexual function in older men without negatively affecting prostate health.
