Garner's Cloning and Stem Cells

Which of the following is NOT a source for stem cells?

• umbilical cord blood 
• early embryos 
• sperm and eggs 
• certain adult tissues 

Why might stem cell research lead to a cure for diabetes?

• Stem cells can be used to grow pancreas cells that produce insulin.
• Stem cells can create babies that have normal functioning pancreases.

Stem cells are

• cells that grow uncontrollably.
• undifferentiated and can develop into many types of cells.
• cells that never go through cell division.
• only found in embryos.

Which of the following cells is undifferentiated?

• cardiac muscle cell
• nerve cell
• liver cell
• stem cell

What process best explains how muscle cells and nerve cells can develop from the same fertilized egg?

• genetic engineering
• survival of the fittest
• differentiation
• selective breeding

What is the difference between embryonic stem cells and adult stem cells?

• Embryonic stem cells can differentiate into more cell types than adult stem cells
• Adult stem cells are pluripotent, just like embryonic stem cells
• Adult stem cells can differentiate into more cell types than embryonic stem cells
• Adult stem cells grow bigger than embryonic stem cells

Medical research involving stem cells is important for ...

• to test the effectiveness of new drugs

• the generation of cells and tissues that can be used in cell based therapies

• to understand the consequences of turning genes off and on

• All of the above

Which is true about embryonic stem cells?

• They no longer divide, their cell type is set and cannot change.
• They can develop into only one type of cell.
• They can become any cell type in the body.
• They are found in adults.

Which type of cell is unspecialized?

• skin cell
• stem cell
• liver cell
• muscle cell

Which stem cells have the most potency?

• Multipotent
• Pluripotent
• Totipotent
• Unipotent
