Stem Cell Exercise

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

Stem cells are ____________________.

• cells that grow uncontrollably

• undifferentiated cells that can turn into other types of cells

• the first cells of a new living organism (fertilized egg)

• specialized cells that do one job

Stem cells are used to __________.

• make clones
• create new species of animals
• make babies
• grow different types of tissues

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

• Embryonic can differentiate into more cell types than adult
• Adult only turn into blood, while embryonic turn into many things.
• Adult can differentiate into more cell types than embryonic
• Adult grow bigger than embryonic

Stem cells can be obtained from _________.

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

Adult (tissue-specific) stem cells can also be referred to as ______________.

• somatic stem cells

• embryonic stem cells

• starter cells

• IPS cells

What does unipotent mean?

• The turning on and off of genes within a cell

• Capable of giving rise to only one cell type

• The specialization of cells occurring during an organism's development

• Capable of giving rise to several different cell types

What does "multipotent" mean?

• able to divide and make one kind of cell
• able to divide and make all different types of cells
• able to divide and make multiple (but not all) types of cells 
• cannot divide

What is a benefit of using the patient's own stem cells to treat cancer?

• Your own stem cells won’t cause rejection as they’re taken from the patient themselves

• Your own stem cells have to be extracted from the bone marrow which is very painful

• Adult stem cells can only differentiate into a few cell types

• There is a risk of cancer returning

What does "pluripotent" mean?

• able to divide and make all 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
