What is an adult stem cell?

An adult stem cell is a simple cell in the body that can divide and change into some other types of cell.

Give two places in the body where adult stem cells are found.

They are found in bone marrow and in the skin. They are also found in the lining of the gut.

What is the main role of adult stem cells in the body?

Their main role is to replace damaged or worn-out cells and help repair tissues.

What does 'multipotent' mean for an adult stem cell?

It means the cell can turn into a limited range of related cell types, not any cell in the body.

How are adult stem cells different from most specialised body cells?

Most specialised cells cannot change type, but adult stem cells can divide and then become new specialised cells.

Where are adult blood stem cells found, and what do they make?

They are found in bone marrow and they make red blood cells, white blood cells and platelets.

Why do adult stem cells need to keep dividing?

They need to keep dividing so the body always has new cells to replace cells that die.

Can an adult stem cell usually change into every type of cell in the body?

No. Adult stem cells can only change into a few types of cell, usually from the tissue where they are found.

How do adult stem cells in the skin help heal a cut?

Adult stem cells in the skin divide to make new skin cells, which grow to close and repair the cut.

Are adult stem cells only found in adults?

No. They are also found in children and babies, not just in fully grown adults.
