Oestrogens are key for bone growth during puberty in both boys and girls.

Epidermal stem cells are diverse and vary in activity, playing key roles in skin maintenance and repair.

Zinc is effective for treating various skin conditions, including warts and acne.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Blocking COX, especially COX-2, in the skin can reduce inflammation and pain and may help prevent skin cancer.

The new "differential stripping" method effectively measures how much substance gets into hair follicles.

Latanoprost can make eyelashes longer, thicker, and darker.

Early development of hair, teeth, and glands involves specific signaling pathways and cellular interactions.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

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

Effective treatments for male pattern baldness include oral finasteride and topical minoxidil, while topical minoxidil is best for female pattern baldness.

Stem cell self-renewal is complex and needs more research for full understanding.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

Some viruses can cause cancer by changing cell processes and avoiding the immune system; vaccines and targeted treatments help reduce these cancers.

K6hf is a unique protein found only in a specific layer of hair follicles.

Estrogen replacement can improve skin health in menopausal women but doesn't reverse sun damage or prevent hair loss.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Some vitamins and minerals like vitamin D and iron can help with certain types of hair loss, but more research is needed for others.

Feather patterns in birds are shaped by signaling interactions and cell movements, with EDA/EDAR crucial for pattern formation.

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.

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

Nanoparticles can improve skin drug delivery but have challenges like toxicity and stability that need more research.

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.

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

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

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

Fibroblast growth factor receptor signaling controls cell development and repair, and its malfunction can cause disorders and cancer, but it also offers potential for targeted therapies.

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

Trilostane effectively and safely treats dogs with pituitary-dependent hyperadrenocorticism, improving symptoms and adrenal gland size.

Wnt and Notch signaling help wound healing by promoting cell growth and regulating cell differentiation.
