Understanding different types of skin cells, especially fibroblasts, can lead to better treatments for wound healing and less scarring.

Aging causes skin stem cells to work less effectively.

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.

Minoxidil promotes hair growth in male pattern baldness.

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.

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

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

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

Hair ages due to genetics and environmental factors, leading to graying and thinning, with treatments available for some conditions.

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.

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

The skin protects the body and is constantly renewed by stem cells; disruptions can lead to cancer.

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.

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

Jasmonic acid and its derivatives play important roles in plant health and have potential uses in medicine and agriculture.

Hair grays due to oxidative stress and fewer functioning melanocytes.

The conclusion is that hair growth can be improved by activating hair cycles, changing the surrounding environment, healing wounds to create new hair follicles, and using stem cell technology.

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

Long-term testosterone therapy can cause hormone suppression, affect prostate and heart health, and alter physical characteristics, but does not increase prostate cancer risk and needs more research for full risk assessment.

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

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