What’s the difference between a stem cell and a differentiated cell?

• Stem cells don’t have a function whereas differentiated cells do.

What are the risks of stem cell treatment?

• Stem cells carry diseases.

• Stem cells will not be accepted by the host and the patient could reject the stem cells.

• Stem cells are infectious cells that could kill people.

Which is true about Embryonic Stem Cells.

• They no longer do mitosis, their cell type is set and can not change
• They are limited to the type of cell they can become
• They can become any cell type in the body
• They are found in adults
