Ms. Kahn’s class is discussing stem cell research.
“Obtaining stem cells from embryos seems wrong to me,” says Gabriel.
“But think about all the good that can be done with stem cells,” says Toni. “People who are paralyzed or have other major medical problems could finally live full lives again!”
“Has anyone investigated other ways to retrieve stem cells other than from embryos?” asks Gabriel.
“Actually,” says Sylvia, “there are also stem cells in adult bone marrow, and scientists have some exciting theories about how these stem cells can help improve many health problems, such as heart attacks!”
“Fascinating,” says Ms. Kahn. “Let’s take a look!”
Ms. Kahn and her class found this topic very interesting and did some research on the internet. Sylvia took notes on information from a study that tested if bone marrow stem cells were effective.
Did the patients who received injections of stem cells instead of a placebo benefit from the treatment? If so, how?
Stem cells from bone marrow are slightly different than stem cells from embryos; they cannot develop into as many different types of cells as embryonic stem cells can. Summarize your position on whether or not scientists should focus only on research that does not involve human embryos.
Discussion Question:
Why is it important that scientists use placebos when they test a new therapy?
