stem cells

Question 1

Suggest how the transplanted stem cells reduce proteinuria.

Answer 1

ability to specialise and divide into healthy glomerulus cells so reduces protein in urine

Question 2

Some scientists have concluded that this method of gene therapy will be a
more effective long-term treatment for SCD than HSCT. Use all the
information provided to evaluate this conclusion.

Answer 2

Donner not needed
less chance of rejection
no destruction of bone marrow
HOWEVER FAULTY CELLS STILL PRODUCED

Question 3

Suggest how iPS cells could correct red-green colour blindness.

Answer 3

specialise into working photoreceptors and can divide

Question 4

The use of iPS cells could have advantages over the use of gene therapy to
correct red-green colour blindness

Answer 4

2. (Use of iPS cells) less chance of rejection/immune response;
3. (Use of iPS cells) single treatment;
4. Harm/side effects from using viruses
