TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

Finasteride safely lowers DHT levels without affecting testosterone.

Hair follicles may soon be used more for targeted and systemic drug delivery.

Pregnancy can cause skin darkening, varicose veins, more sweating, hair growth, hair loss after birth, nail changes, and gum inflammation.

Keratose, derived from human hair, is a non-toxic biomaterial good for tissue regeneration and integrates well with body tissues.

Sonic hedgehog signaling is crucial for hair growth and maintaining hair follicle identity.

Low fluence photoepilation temporarily removes hair by targeting the hair follicle's pigmented area without severe damage.

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

Obesity worsens PCOS symptoms, and PCOS may lead to more weight gain; managing both requires a holistic approach that includes mental health.

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.

Early detection and intensive treatment of diseases caused by Staphylococcus aureus toxins are crucial for reducing severe health effects.

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

New targets for making and using brain-synthesized steroids could lead to better treatments for brain disorders and alcoholism.

No single treatment is consistently effective for alopecia areata, and more research is needed.

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

Vitamin D has potential benefits for cancer prevention, heart health, diabetes, obesity, muscle function, skin health, and immune function, but clinical results are mixed and more research is needed.

Rhodococcus equi causes severe pneumonia in young foals, and effective vaccines are needed due to foals' weak immune responses.

The update highlights that non-classic congenital adrenal hyperplasia is common in women with excess male hormones, requires specific hormone tests for diagnosis, and has various treatment options depending on age and symptoms.

Combining liraglutide and metformin helps obese women with PCOS who didn't lose weight on metformin alone to lose more weight.

Children, especially teenagers, can get severe SARS-CoV infection with symptoms similar to adults, but they typically recover well with supportive care.

Aminopterin strongly suppresses epithelial tissues and can treat certain skin conditions but has significant side effects.

Tiny particles from stem cells help activate hair growth cells and encourage hair growth in mice without being toxic.

Fetal wound healing changes with development, affecting inflammation and collagen, which may influence scarring.

Microneedling is promising for treating various skin issues but needs more research to confirm its effectiveness and safety.

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

PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.

Correct skin biopsy techniques are crucial to avoid misdiagnosis of skin diseases.

Recombinant cytokine therapy can cause skin reactions ranging from mild to severe.

MicroRNA-214 is important for skin and hair growth because it affects the Wnt pathway.
