Stem Cells

Which stem cells have the most potency?

• Multipotent
• Pluripotent
• Totipotent
• Unipotent

Stem cells are

• cells that grow uncontrollably
• undifferentiated and can be any type of cell
• never go through cell division
• only found in embryos

Stem cells can be obtained from

• embryos
• some adult tissues
• umbilical cord blood
• all of the above

Why is using umbilical cord blood beneficial?

• immune compatible
• can be stored & used later
• contains stem cells 
• all of the above

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 do stem cells have to do with clones?

• Stem cells can divide and differentiate  and grow into a clone
• Clones can be grown from stem cells
• Both choices are correct
• None of these choices are correct

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

• Use stem cells to grow pancreas cells that make insulin
• Use stem cells to make babies that do not have diseases

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

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

• All blood cells
• All brain cells
