Epigenetic changes control how adult stem cells work and can lead to diseases like cancer if they go wrong.

FDG PET/CT scans can change cancer treatment plans for dogs.

Human sweat glands have a type of stem cell that can grow well and turn into different cell types.

Syndecan-1 is essential for maintaining skin fat and preventing cold stress.

Epithelial stem cells can adapt and help in tissue repair and regeneration.

The same hormone can affect gene expression differently in various tissues, which could lead to new treatments for conditions like hair loss.

Ectodysplasin inhibits Wnt signaling to help form hair follicles.

Cidea is essential for proper lipid storage and secretion in sebaceous glands, affecting skin and hair health.

Skin cells show flexibility in healing wounds and forming tumors, with potential for treating hair disorders and chronic ulcers.

Glucocorticoids and sex hormones affect skin health, with potential for targeted treatments to minimize side effects and treat skin conditions.

The document concludes that hair loss is complex, affects many people, has limited treatments, and requires more research on its causes and psychological impact.

Different human traits like skin color and hair type vary between populations due to genetic adaptations to the environment.

Understanding phenotypic plasticity is crucial for developing effective cancer therapies.

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

Understanding where cancer cells come from helps create better prevention and treatment methods.

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.

Hair follicles produce and respond to melatonin, affecting hair growth and sensitivity to estrogen.

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

Prolactin affects hair growth cycles and can cause early hair follicle regression.

Human hair follicles can make and process prostaglandins, which may affect hair growth.

RANK-RANKL signaling is essential for hair growth and skin health.

Skin tumor regression is helped by retinoic acid signaling blocking Wnt signaling.

Hormones during pregnancy and lactation keep skin stem cells inactive, preventing hair growth.

Blocking the prolactin receptor might help treat various diseases, but more research is needed.

Sex hormones affect hair and feather growth and may help manage alopecia and hormone-dependent cancers.

Stem cells can rejuvenate skin, restore hair, and aid in wound healing.

Estrogen is important for keeping adult mouse nipple skin healthy by controlling certain cell signals.

Dermal papilla cells are key for hair growth and color, influencing hair type and size, and their interaction with stem cells could help treat hair loss and color disorders.

Hair loss needs more research for better treatments.

Telocytes might help with skin repair and regeneration.
