Sweat gland development involves two unique skin cell programs and a temporary skin environment.

Newly born mesenchymal cells quickly spread out in response to tissue tension during early development.

Hair follicles can be used to quickly assess drug effects in cancer treatment.

Hair graying is caused by the loss of pigment cells due to poor maintenance of stem cells in the hair follicle.

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

Certain proteins, Lgr5 and Lgr6, are important markers of adult stem cells and are involved in tissue repair and cancer development.

Wnt1/βcatenin signaling is crucial for heart repair after injury.

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 grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

Stress increases a factor in mice that leads to hair loss, and blocking this factor may prevent it.

We need more research to better understand human hair follicle stem cells for improved treatments for hair loss and skin cancer.

Nerves and chemicals in the body can affect hair growth and loss.

A WNT10A gene mutation leads to ectodermal dysplasia by disrupting cell growth and differentiation.

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

NF-κB is crucial for zebrafish heart repair, affecting heart cell growth and repair processes.

Animal models have helped understand hair loss from alopecia areata and find new treatments.

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

New methods have greatly improved our understanding of stem cell behavior and roles in the body.

YAP and TAZ proteins are necessary for the development of two types of skin cancer.

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.

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

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

Leptin, a hormone, is important for starting hair growth.

Live imaging has advanced our understanding of stem cell behavior and raised new research questions.

Topical anthralin helped regrow hair in mice with a condition similar to human alopecia.

Smad4 is important for healthy hair follicles because it helps produce a protein needed for hair to stick together and grow.

Mice with LSS deficiency showed hair loss and cataracts, similar to humans, and can help in understanding and treating this condition.

Arabidopsis collet hairs are good for studying nuclear movement and DNA content increase during growth.

A protein called sFRP4 from skin cells stops the development of pigment-producing cells in hair.

The study concluded that a protein important for hair strength is regulated by certain molecular processes and is affected by growth phases.
