Arrector pili muscle regulates hair follicle stem cells, DNA methylation needed for hair cycling, and Wnt/B-catenin signaling starts hair growth.

Some wound-healing cells can turn into fat cells around new hair growth in mice.

The Rotterdam Study updated findings on elderly health, focusing on heart disease, genetics, lifestyle effects, and disease understanding.

Super-enhancers controlled by pioneer factors like SOX9 are crucial for stem cell adaptability and identity.

The skin has a complex immune system that is essential for protection and healing, requiring more research for better wound treatment.

The secretome from mesenchymal stem cells is a promising treatment that may repair tissue and avoid side effects of stem cell transplantation.

The Rotterdam Study aims to understand disease causes in the elderly and has found new risk factors and genetic influences on various conditions.

TGF-β is crucial for tissue repair and can cause diseases if not properly regulated.

Tofacitinib is safe and effective for severe alopecia areata, but hair loss may return 2 months after stopping treatment.

Lactate production is important for activating hair growth stem cells.

Hair follicle development and microbes help regulatory T cells gather in newborn skin.

Men are more likely to have severe COVID-19 cases and fatalities than women due to factors like lifestyle, aging, and biological differences.

Researchers created human hair follicles using a new method that could help treat hair loss.

Alopecia areata involves immune activation in the scalp, suggesting treatments targeting TH1, TH2, and IL-23 pathways.

Different types of skin cells have unique genetic markers that affect how likely they are to spread cancer.

Tight junctions are key for skin protection and controlling what gets absorbed or passes through the skin.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

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.

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

Cepharanthine is a well-tolerated drug with multiple medical uses, including anti-inflammatory and anti-cancer properties.

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

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

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.

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

Mice studies show that Protein Phosphatase 2A is crucial for cell growth, development, and disease prevention.

The article concludes that better understanding gene regulation related to seasonal changes can offer insights into the mechanisms of seasonal timing in mammals.

Hidradenitis suppurativa is caused by genetic factors, inflammation, bacteria, hormones, and lifestyle factors like obesity and smoking.

Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.
