Question

which of the following treatment options would be more promising for a patient with a spinal cord injury?
o a. the use of stem cells harvested from his own bone marrow or skin cells
o b. the use of transplanted stem cells harvested from fetal fruit flies
o c. a tissue transplant or graft using fetal pig tissue
o d. the use of neural cells harvested directly from the patients central nervous system

Explanation:

Stem cells from a patient's own bone - marrow or skin are autologous, reducing the risk of immune - rejection. Fetal fruit flies are not a source of cells for human treatment. Fetal pig tissue may cause immune - rejection and ethical issues. Harvesting neural cells directly from the central nervous system can cause further damage.

Answer:

A. The use of stem cells harvested from his own bone marrow or skin cells
