Chapter 2.1, Problem 15RQ

Explain the difference between asymmetric and symmetric cell division.  When the pool of stem cells for a particular tissue needs to expand, which of these two cell division mechanisms is utilized?

What is the difference between the different kinds of STEM cells?

What does "potency" mean in the context of stem cells? The power of cells to influence their surroundings The ability of cells to differentiate into specialized cell types The ability of cells to survive under harsh environmental or culture conditions Both A and B

Using the terms potency, specificity, and differentiation in each, compare and contrast the difference between adult and embryonic stem cells. 1.Adult Stem Cells: 2. Embryonic Stem Cells:

What are the mechanisms governing stem cell division, self-renewal, and differentiation?

Distinguish between the categories of stem cells

How do somatic stem cells differ from embryonic stem cells?

Explain how stem cells and progenitor cells make possible the growth and repair of tissues.

Reports in the media about stem cells usually state that they “turn into any kind of cell in the body.” Explain why this statement is only partially correct, including a description of how a stem cell maintains the population of stem cells.
