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

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.

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.

Low doses of some substances can be beneficial, while high doses can be harmful or toxic.

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

A specific drug can help treat Lichen Planopilaris, a condition causing permanent hair loss.

Lampreys have a functional vitamin D receptor that may help detoxify harmful substances.

Hormones and metabolism play a complex role in prostate enlargement, and more research is needed to improve diagnosis and treatment.

Turing patterns are now recognized as important in developmental biology.

Activin helps skin growth and healing mainly through stromal cells and affects keratinocytes based on its amount.

Skin has specialized touch receptors that can tell different sensations apart.

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.

Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.

Some heart drugs show promise for other conditions, but more research is needed to confirm their effectiveness and safety.

A protein called CBP is found in prostate cancer and can increase the effectiveness of certain prostate cancer treatments.

Cepharanthine, a Japanese hair loss drug, shows promise as a COVID-19 treatment but needs more testing.

Advanced human skin models improve drug development and could replace animal testing.

Air pollution (PM10) increases skin inflammation and aging by reducing collagen and may trigger a repair response in skin cells.

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

Neurosteroids show promise for treating epilepsy and more research is needed.

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

New findings explain how genetic changes, body clocks, and certain molecules affect tissue response to stress hormones.

Activating β-catenin in different skin stem cells causes various types of hair growth and skin tumors.

The document explains different types of hair loss, their causes, and treatments, and suggests future research areas.

Botox increased hair count in men with baldness and might work by improving scalp blood flow.
