The circadian clock is crucial for tissue renewal and regeneration, affecting stem cell functions and having implications for health and disease.

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

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.

CRISPR-Cas9 can successfully edit genes in large mammals like Cashmere goats.

Thyroid hormones are important for skin health and changes in them can affect conditions like hair loss and eczema.

Skin organoids are a promising new model for studying human skin development and testing treatments.

Blocking the NOTCH pathway can prevent fibrosis in systemic sclerosis.

R-spondins and their receptors help increase bone growth and may be used to treat bone loss diseases.

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

iPSCs help understand and treat neurodevelopmental disorders.

Stem cells can improve skin grafts by enhancing blood flow and hair growth.

New treatments for immune disorders caused by FOXN1 deficiency are promising.

Wounds heal without scarring in early development but later result in scars, and studying Wnt signaling could help control scarring.

Mice can regenerate ear tissue without the p53 protein.

Wound covers with α-13'-COOH from vitamin E can improve and speed up wound healing.

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

Environmental cues can change the fate and function of epithelial cells, with potential for cell therapy.
