Stem Cells and Cell Differentiation
1. What are stem cells? Where are they found? What types of cells do they produce? And why are stem cells important for tissue health?
2. Define each of the following terms:
Cellular differentiation:
Differential gene expression:
Embryonic stem cells:
Adult stem cells:
Multipotent:
Pluripotent:
Totipotent:
3. Indicate what, if any, difference there is in differentiation potential between adult and embryonic stem cells.
4. Some scientists argue that embryonic stem cells have greater therapeutic value than do adult stem cells. Why?
5. Outline the process of somatic cell nuclear transplantation and describe the two potential outcomes of the process.
