EXIT TICKET: Stem Cells in the Spotlight Webquest_3.13.25

What is the primary characteristic of stem cells that allows them to be used in regenerative medicine?

• They can transform into a variety of specialized cells.

• They are incapable of dividing.

• They are already specialized with limited potential.

• They are non-functional and dead.

A specialized cell cannot become any other type of cell.

• It cannot; cell specialization is irreversible.

• It can, by de-differentiation.

• It can, via reprogramming under certain conditions.

• It depends on the cell type.

Which stem cell type has the highest potential as therapy?

• Embryonic (ES)

• Somatic (Adult)

• Induced Pluripotent (iPS)

• Therapeutic Cloning

What are three sources of stem cells that can be used to treat blood-based diseases?

• Bone marrow

• Peripheral blood stem cells

• Umbilical cord blood

Tissue engineers have also grown whole organs like kidneys and livers in animal models. Which organs have been grown in these animal models?

Which statement best describes the federal stance on embryonic stem cell research in the U.S.?

• Federal funding is allowed for embryonic stem cell research but with certain restrictions and guidelines.

• Embryonic stem cell research is entirely prohibited by federal law.

• There are no federal laws governing embryonic stem cell research.

• Embryonic stem cell research is fully supported and funded without any restrictions.

Cancer, or tumors, can occur in various parts of the body.
