Damaging mitochondrial DNA in mice speeds up aging due to increased reactive oxygen species, not through the p53/p21 pathway.

The p53 protein helps control hair follicle shrinking by promoting cell death in mice.

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.

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

The document suggests that activating autophagy might help with regeneration by removing old and damaged cells.

PDGF signaling is crucial for maintaining and renewing hair follicle stem cells, which could help treat hair loss.

Hdac1 and Hdac2 help maintain and protect the cells that control hair growth.

Researchers found stem cells in dog hair follicles using specific markers.

Cutaneous Lymphadenoma is a unique skin tumor with specific protein markers and common gene mutations that may cause continuous cell growth.

GATA6 is important for maintaining and differentiating cells in a key area of human skin.

Eclipta alba extract helps increase hair growth and decrease hair loss-related protein in mice.

The study found new details about human hair growth and suggests that preventing a specific biological pathway could potentially treat hair graying.

Melanocyte precursors in human fetal skin follow a specific migration pattern and some remain in the skin's deeper layers.
