Stem cell self-renewal is complex and needs more research for full understanding.

Trilostane effectively improved symptoms in dogs with a certain adrenal gland disorder.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

Sonic hedgehog signaling is crucial for hair growth and maintaining hair follicle identity.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.
