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

Different types of stem cells and their environments are key to skin repair and maintenance.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

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

GDNF helps grow hair and heal skin wounds by acting on hair stem cells.

Eating fewer calories improves the ability of stem cells to repair and renew the body in various tissues.

The exact identity of skin stem cells and how skin cells differentiate is not fully known.
