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

Periodontal ligament stem cells show promise for regrowing tissues but require more research for safe, effective use.

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

Different types of stem cells and their environments are key to skin repair and maintenance.

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

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.

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.

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

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

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

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

Male hormones and their receptors play a key role in hair loss and skin health, with potential new treatments being explored.

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

Melanocytes are crucial for skin pigmentation and can affect conditions like melanoma, vitiligo, and albinism, as well as hair color and hearing.

Skin fat helps with body temperature control and has other active roles in health.

Genetics and hormones play a role in male and female hair loss, but more research is needed to fully understand it.

TCDD speeds up skin barrier formation by increasing certain gene expressions.

Skin development in mammals is controlled by key proteins and signals from underlying cells, involving stem cells for maintenance and repair.

Drosha and Dicer are essential for hair follicle health and preventing DNA damage in skin cells.

Certain genes control the color of human hair by affecting pigment production.

Correcting nutrient deficiencies may help with hair loss, but the benefits of supplements without a deficiency are uncertain and could be harmful.

Fat cells are important for healthy skin, hair growth, and healing, and changes in these cells can affect skin conditions and aging.

Dermal Papilla cells are a promising tool for evaluating hair growth treatments.

Costunolide may have multiple health benefits, including promoting hair growth and protecting against cancer and diabetes, but more research is needed.

LGR5 helps maintain corneal cell characteristics and prevents unwanted changes by controlling specific cell signaling pathways.

Keratin proteins are crucial for healthy skin, but mutations can cause skin disorders with no effective treatments yet.

PCOS affects women's health by increasing the risk of diabetes, heart disease, and reproductive issues.

Air pollution (PM10) increases skin inflammation and aging by reducing collagen and may trigger a repair response in skin cells.

Hormones and genetics affect hair growth and patterns, with some changes reversible and others not.
