Stem Cells and Uncontrolled Growth

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

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

Neural stem cells from the brain can differentiate into... 

• only specialized brain cells .
• specialized brain cells and specialized skin cells. 
• all types of specialized cells. 
• only specialized blood cells. 

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 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

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.

What does "pluripotent" mean?

• able to divide and make many different types of cells
• not able to divide
• can only divide and make one cell type 
• if it divides, it will make a cancerous tumor

What are iPS cells, and what do they mean to stem cell research?

• Induced purpose stem cells, mean embryo cells were made into adult-like cells
• Induced purpose stem cells, mean adult cells were reversed to baby cells
• Induced pluripotent stem cells, mean adult cells were made into embryo-like cells
• Induced pluripotent stem cells, mean cells were totipotent and are now pluripotent
