Embryonic stem cells • Embryonic stem cells supply new cells for an embryo

Embryonic stem cells
• Embryonic stem cells supply new cells for an embryo? as it grows and develops into a baby.
• These stem cells are said to be pluripotent, which means they can change into any cell in the body.
Adult stem cells
• Adult stem cells supply new cells as an organism grows and to replace cells that get damaged.
• Adult stem cells are said to be multipotent, which means they can only change into some cells in the body, not any cell, for example: 
• Blood (or ‘haematopoietic’) stem cells can only replace the various types of cells in the blood.
• Skin (or ‘epithelial’) stem cells provide the different types of cells that make up our skin and hair.
