Describe several potential applications for embryonic stem cell research
What will be an ideal response?
Answers provided here will vary. It is most likely that students will describe how stem cells have the potential to cure many different human conditions. In particular, students will likely discuss how somatic cell nuclear transplant (SCNT) can be used to produce cells that can be coerced into differentiating into a specific cell type needed by a patient.
