Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

The study found that certain genes are important for hedgehog skin appendage development and immunity, with spines possibly evolving for protection and infection resistance.

sPLA2-X is crucial for normal hair growth and follicle health.

Scientists created keratinocyte cell lines from human hair that can differentiate similarly to normal skin cells, offering a new way to study skin biology and diseases.

Adult stem cells with Tp63 can form hair and skin cells when placed in new skin, showing they have hidden abilities for skin repair.

The we/we wal/wal mice have defects in hair growth and skin layer formation, causing hair loss, useful for understanding alopecia.

The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.

EZH2 levels decrease as fetuses develop and are higher in adult skin, which may affect skin growth and repair.

Dermal-epidermal interactions are crucial for hair growth and maintenance.
