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

The circadian clock affects skin stem cell behavior, impacting aging and cancer risk.

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

Chitin and chitosan are useful in cosmetics for oral care, haircare, and skincare, including UV protection and strength improvement.

Some patients taking finasteride or dutasteride may have ongoing sexual problems and depression even after stopping the medication.

Eph receptors and ephrins may be promising targets for treating diseases, but more understanding is needed for effective and safe therapies.

Insulin resistance and obesity are key factors in the development and worsening of polycystic ovary syndrome, and lifestyle changes are important for managing it.

Planarian regeneration begins with a specific gene activation caused by injury, essential for healing and tissue regrowth.

High levels of male hormones, insulin resistance, and obesity are closely linked and worsen polycystic ovary syndrome, but more research is needed to improve treatments.

Targeted cancer therapies often cause serious skin problems that need careful management.

Capsaicin, found in chili peppers, can slow down hair growth by affecting skin cells and hair follicles.

Myrtle has various health benefits and potential for medicine development.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

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

Minoxidil boosts hair growth by increasing cell production and survival.

Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.

Cathepsin L is essential for normal hair growth and development.

Aging causes skin stem cells to work less effectively.

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.

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

Stress can cause hair loss by negatively affecting hair follicles and this effect might be reversed with specific treatments.

Eclipta alba extract may help hair grow similarly to Minoxidil.

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 research identified various cell types in mouse and human teeth, which could help in developing dental regenerative treatments.

Smoking harms the skin, causing early aging and increasing cancer risk, but stopping smoking can improve skin health.

Melatonin helps regulate hair growth and protects the hair follicle from stress.

Olive oil compounds may help prevent cancer in animals, but human results are mixed.

Laminin-511 is crucial for early hair growth and maintaining important hair development signals.

Prolactin affects hair growth and skin conditions, and could be a target for new skin disease treatments.
