Deleting the PTEN gene in mice causes nerve cells to grow larger and heal better after injury, but may cause overgrowth and hair loss in older mice.

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

New treatments for diabetes, central nervous system repair, and cartilage injury were found, and a way to create functional hair follicles from stem cells was developed.

The research showed how melanocytes develop, move, and respond to UV light, and their stem cells' role in hair color and skin cancer risk.

Meis2 is essential for touch sensation and proper nerve connection to touch receptors in certain skin areas of mice.

Compartmentalized organization might be crucial for stem cells to effectively respond to growth or injury.

Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.

Matriptase is crucial for keeping epithelial tissues healthy and functioning properly.

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

BLIMP1 is essential for skin maintenance but not for defining sebaceous gland progenitors.

Dermal adipose tissue in mice can change and revert to help with skin health.

New cells are added to the hair's dermal papilla during the active growth phase.

The tumor suppressor gene FLCN affects mitochondrial function and energy use in cells.

A new technology showed that the SOX9 gene might control heart scar formation after injury, suggesting new treatment possibilities.

Nestin identifies specific progenitor cells in hair follicles that can become outer root sheath cells.

Nestin-expressing cells turn into a specific type of skin cell in hair follicles during development and in adults.

The document concludes that the development of certain tumors is influenced by genetic background and that a specific gene modification can lead to tumor regression and reduced growth.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

Hair loss and aging are caused by the breakdown of a key protein in hair stem cells.

More dermal papilla cells in hair follicles lead to larger, healthier hair, while fewer cells cause hair thinning and loss.

Lactate production is important for activating hair growth stem cells.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

Notch/CSL signaling controls hair follicle differentiation through Wnt5a and FoxN1.

Blocking β-catenin in skin cells improves hair growth during wound healing.
