Vitamin D and its receptor regulate skin functions like cell growth, immunity, hair cycle, and tumor prevention.

The document concludes that recognizing and treating cutaneous lupus erythematosus early is crucial for managing the skin and potential systemic symptoms.

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

Male pattern baldness involves genetics, hormones, and needs better treatments.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

Estrogen therapy can reduce skin aging but has cancer risks.

Aging causes skin stem cells to work less effectively.

Postpartum depression is linked to changes in brain chemicals, inflammation, stress, and certain genes, and can potentially be identified by markers like specific steroids, serotonin levels, and vitamin D levels.

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

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.

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.

Normal skin cell renewal doesn't need RAR signaling, but vitamin A-related skin thickening does.

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

Foxp3 is crucial for regulatory T cell function, and targeting these cells may help treat immune disorders.

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

Targeting androgen receptors could be a promising way to treat skin disorders with fewer side effects.

Male pattern baldness involves hormones and cell signals affecting hair growth.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

Estrogens help reduce skin aging, and SERMs might offer similar benefits without the risks of hormone therapy.

Asia has made significant progress in tissue engineering and regenerative medicine, but wider clinical use requires more 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.

The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.

MIM is crucial for hair follicle formation and regeneration by controlling cilia formation and hedgehog signaling through its interaction with Cortactin and Src.

Adult female acne treatment should be personalized, considering individual preferences and pregnancy, using various topical and oral medications while managing side effects and resistance.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

Androgens have complex effects on hair growth, promoting it in some areas but causing hair loss in others, and our understanding of this is still evolving.

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