      1. True or False: A stem cell is an unspecialized cell.
        1. True
        2. False

        1. Stem cells are unspecialized (or, undifferentiated) cells that have the capability to become other types of cells in the human body.

      2. True or False: A stem cell can give rise to specialized cell types.
        1. True
        2. False

        1. What makes stem cells so exciting is that they potentially can be used to repair cells damaged by disease or injury, in fact they can become over 200 cell types.

      3. True or False: Stem cells can only divide and renew themselves for up to 24 hours.
        1. True
        2. False

        1. If stem cells are in the right environment, such as a culture, they have the capability to divide and renew themselves for an extended or even infinite period of time.

      4. True or False: An adult stem cell is limited in differentiating into different cell types.
        1. True
        2. False

        1. An adult stem cell is limited in the type of cell it can differentiate into. Therefore these adult stem cells typically differentiate into cells from their tissue of origin. For example, a stem cell from bone marrow (where blood is made) will typically differentiate into blood cells.

          An exception to this theory, however, might lie in induced pluripotent stem cells (ips cells), wherein genes are introduced into a somatic cell which cause adult cells to exhibit properties of embryonic stem cells. This breakthrough, made in 2007, is an exciting line of research, however it is still very new and causes cells to behave unpredictably.

      5. True or False: Embryonic stem cells are limited in differentiating into varying cell types
        1. True
        2. False

        1. Embryonic stem cells have the ability to differentiate into all cell types. As a result, embryonic stem cells are considered to be the "gold standard" in stem cell research.

      6. True or False: Stem cells are derived from aborted fetuses.
        1. True
        2. False

        1. Stem cell research is in no way related to abortion or the issue of choice. There is no type of stem cells that come from abortion procedures, and that goes for embryonic stem cells, as well. These cells come from a fertilized egg that has no prospect of developing further and would, otherwise, be discarded as medical waste. Abortion plays no role in this whatsoever.

      7. True or False: Currently umbilical cord stem cell transplants are used to treat diseases.
        1. True
        2. False

        1. Stem cells derived from umbilical cord blood are technically adult stem cells and have been used in recent years to treat some diseases, such as blood disorders like Leukemia. However, because they are adult stem cells, their application is fairly limited.

      8. Pluripotent is the ability of a/an:
        1. cell to develop into an adult or embryonic stem cell
        2. stem cell to develop into many different cell types
        3. embryonic stem cell to develop into an adult stem cell
        4. adult stem cell to develop into an embryonic stem cell

        1. All stem cells are pluripotent in that they can differentiate into various cell types.

      9. Therapeutic cloning:
        1. was used in creating Dolly the sheep
        2. is the exact duplication of an organism that already exists
        3. requires implanting a dividing embryo into a host cell
        4. is the production of human embryos for use in research

        1. Stem cell research is about finding cures to disease, and that’s all. There is no part of this research that is interested in cloning people, and there is no scientist looking to do that. Stem cell research is not reproductive cloning in any way, shape, or form. The term “therapeutic cloning” is sometimes used to describe a form of research, but that simply refers to the replication of a piece of genetic material that gets inserted into a somatic (ordinary body cell) for the purposes of study. This is in no way related to cloning people.

      10. Which of the following diseases has/have the potential to be treated with stem cells?
        1. Diabetes and Parkinson's
        2. Heart disease and cancer
        3. Spinal chord injuries and Chron's disease
        4. All of the above

        1. Advances in stem cell research have the potential to treat the leading health risks in the U.S., including cancer, heart disease, HIV, Alzheimer’s, Parkinson’s, diabetes, spinal cord injury, and many others.

          In the United States*:

          • One million children live with juvenile diabetes
          • One million people live with Parkinson’s disease
          • 4.5 million suffer from Alzheimer’s disease
          • 2.5 million people live with multiple sclerosis
          • 450,000 people are paralyzed by spinal cord injury
          • 30,000 people face ALS
          • 58 million people live with heart disease
          • 8.2 million people face cancer
          • 10 million people are confronted with osteoporosis
          • 43 million people suffer from arthritis
