Terms in this set (12)
What are undifferentiated cells?
Stem cells, they divide frequently and are able to change into all types of cells
Where are stem cells found?
In early human embryos or the bone marrow of adults
what is the advantage of using stem cells?
they can become any type of cell
where can stem cells be found in a adult?
in bone marrow
what can stem cells found in bone marrow only form?
where are stem cells grown?
in a lab
What could embryonic stem cells be used for?
-Insulin producing cells for people with diabetes
-Nerve cells for people paralysed by spinal injuries
what is it called when the embryo can have the same genetic information as the patient?
what does this mean?
the patients body can't reject the cell as it will be used for faulty cells.
what are the risks of growing stem cells in a lab?
contaminated with a virus which if had been injected into the patient make them sicker.
Why are some people against stem cell research?
- human embryos shouldn't be used for experiments since each one is potential human life
- the embryos have the potential to be babies and are destroyed
- the embryo can't give permission
- research is expensive
in plants where are the stem cells found?
throughout the plants life, what do the meristems do?
what can these stem cell do?
differentiate into any type of plant cell
