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

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

The dermal papilla is crucial for hair growth and health, and understanding it could lead to new hair loss treatments.

The document concludes that a better understanding of cell changes during wound healing could improve treatments for chronic wounds and other conditions.

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.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

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

MicroRNA-302 helps improve the conversion of body cells into stem cells by blocking NR2F2.

Tiny particles from stem cells help activate hair growth cells and encourage hair growth in mice without being toxic.

Newborn mouse skin cells can grow hair and this process can be recreated in adult cells to potentially help with hair loss.

Using human fat tissue derived stem cells in micrografts can safely and effectively increase hair density in people with hair loss.

Minoxidil and finasteride effectively treat hair loss.

BMP2 and BMP7 have opposite roles in feather formation.

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

Hair follicle regeneration needs special conditions and young cells.

Larger spheroids improve hair growth, but size doesn't guarantee thicker hair.

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

The circadian clock influences the behavior and regeneration of stem cells in the body.

Exosomes from dermal papilla cells help hair growth by making hair follicle stem cells multiply and change.

Maintaining DNA health in stem cells is key to preventing aging and tissue breakdown.

Beta-caryophyllene helps improve wound healing in mice, especially in females.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Certain immune system proteins are important for skin healing but can cause problems if there are too many of them.

Macrophages are vital for skin healing, hair growth, salt balance, and cancer defense.

The p53 protein has complex, sometimes contradictory functions, including tumor suppression and promoting cell survival.

Light can turn on hair growth cells through a nerve path starting in the eyes.

The document concludes that the skin's immune system is complex, involving interactions with hair follicles, nerves, and microbes, and can protect or cause disease, offering targets for new treatments.

The extracellular matrix is crucial for controlling skin stem cell behavior and health.

Improving the environment and cell interactions is key for creating human hair in the lab.

Stem cells help repair tissue mainly by releasing beneficial substances, not by replacing damaged cells.
