Which of the following statements reflect current stem cell research?
a) The stem cell is known as a precursor cell that continually replenishes the body’s entire supply of both red and white cells.
The stem cell is known as a precursor cell that continually replenishes the body’s entire supply of both red and white cells. Stem cells comprise only a small portion of all types of bone marrow cells.
b) Stem cell transplantation can restore immune system functioning.
Research conducted with mouse models has demonstrated that once the immune system has been destroyed experimentally, it can be completely restored with the implantation of just a few purified stem cells.
c) Stem cell transplantion has been performed in the laboratory only.
Stem cell transplantation has been carried out in human subjects with certain types of immune dysfunction such as severe combined immunodeficiency (SCID).
d) Clinical trials are underway in patients with acquired immune deficiencies only.
Clinical trails are underway in patients with a variety of disorders with an autoimmune component including systemic lupus erythematosus, rheumatoid arthritis, scleroderma, and multiple sclerosis.
