Stem cells review

?
What is a stem cell?
A stem cell is an undifferentiated cell which can give rise to more cells of the same type and can differentiate to form other types of cells.
1 of 14
Differentiate
make or become different in the process of growth or development.

What is therapeutic cloning?
When embryonic stem cells are produced with the same genes as the patient and given to them
3 of 14
What stage is the embryonic stem cell derived from?
From a four or five day old human embryo that's in the blastocyst phase of development.

What is an advantage and diasdvantage of using embryonic stem cells?
They are easy to extract from the embryo butembryo destroyed when cells removed - some people think embryos have a right to live.
5 of 14
Most types of animal cells differentiate at an early stage whereas many plant cells...
retain the ability to differentiate throughout life
6 of 14
Stem cells can be made to diferentiate into...
many different types of cells, eg nerve cells.

Treatment with stem cells may be able to help...
cure disease and help conditions such as paralysis

What are 3 uses of stem cells?
Therapeutic cloning, plant cloning and stem cell treatments.
10 of 14
What are 2 disadvantages of stem cells?
Stem cell transplantation could transfer viral infections and it goes against some peoples ethical beliefs.
11 of 14
Embryonic stem cells can turn into any type of cell but...
adult stem cells can only turn into certain ones like blood cells.
12 of 14
What are risks of using stem cells in medicine?
Stem cells grown in the lab could get contaminated with a virus passing it on to the patient.
13 of 14
How can stem cells be used with plants?
Can be used to produce clones of plants and grow more rare plants.
