Mice without the vitamin D receptor have bone issues and other health problems, suggesting vitamin D is important for preventing various diseases in humans.

The vitamin D receptor is crucial for bone health and affects various body systems, with mutations potentially leading to disease.

The document concludes that better targeted treatments are needed for wound healing, and single-cell technologies may improve cell-based therapies.

Keratins help protect cells, aid in cancer diagnosis, and influence cancer behavior and treatment.

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

Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

Msx and Dlx genes are crucial for development, controlling cell behaviors like growth and differentiation through their roles as gene regulators.

Stem cells are crucial for skin repair and new treatments for chronic wounds.

Wnt signaling controls whether hair follicle stem cells stay inactive or regenerate hair.

Telocytes might help with skin repair and regeneration.

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

Too much Smad7 changes skin and hair development by breaking down a protein called β-catenin, leading to more oil glands and fewer hair follicles.

Aging causes skin stem cells to work less effectively.

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

Low oxygen conditions increase the hair-growing effects of substances from fat-derived stem cells by boosting growth factor release.

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.

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.

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

Applying a special compound can promote hair growth without harmful side effects.

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

Fetal wound healing changes with development, affecting inflammation and collagen, which may influence scarring.

Skin-derived precursors in hair follicles come from different origins but function similarly.

The document concludes that certain genetic mutations and dietary factors are involved in acne development, and treatments like isotretinoin and diet changes can help manage it.

The document concludes that adult mammalian skin contains multiple stem cell populations with specific markers, important for understanding skin regeneration and related conditions.

A wearable device using electric stimulation can significantly improve hair growth.

Layer-by-Layer self-assembly is promising for biomedical uses like tissue engineering and cell therapy, but challenges remain in material safety and process optimization.

Activating the Wnt/β-catenin pathway could lead to new hair loss treatments.

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