Question

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

Explanation:

Using stem cells harvested from a patient's own bone marrow or skin cells (autologous stem - cell therapy) has the advantage of reduced immune - rejection risk. Fetal pig tissue may face immune - rejection and ethical issues. Fetal fruit flies are not a source of cells for human spinal cord injury treatment as they are invertebrates with very different biology. Harvesting neural cells directly from the patient's central nervous system is highly invasive and may cause more damage.

Answer:

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