What is a stem cell?

A cell that has not yet become a specialised cell. It can replicate many times and has the potential to become different types of cells.

What are the two types of stem cells?

Adult stem cells: Bone marrow. Embryonic stem cells: From a developing embryo(usually one discarded after IVF).

What is therapeutic cloning?

It's when the nucleus is taken out of a patient's body cell and put into an egg cell which had its nucleus taken out. The egg is stimulated and starts to divide which creates a clone. The stem cells from the embryo is taken out and put in the patient

What stage is the embryonic stem cells derived from?

From a four or five day old human embryo that's in the blastocyst phase of development.

Where is the embryonic stem cells taken from?

They are taken from the embryoblast(inner cell mass) which contains totipotent cells(develops into any cell).

5 of 6

What is an advantage and disadvantage of using embryonic stem cells?

They are easier to work with but putting cells from one body to another means the patient will need to take a lot of medication. However, using stem cells from the patient avoids that problem.
