Which term refers to using adult or embryonic stem cells that can be made into specialized cells?

• A. Immunotherapies
• B. Gene therapy
• C. Immunizations
• D. Stem cell research

Answer: (D)

The main idea here is that stem cells have the ability to become many different specialized cell types. Using adult or embryonic stem cells that can be directed to turn into specific, specialized cells is stem cell research. Embryonic stem cells are pluripotent, meaning they can become many different cell types, while adult stem cells are multipotent, limited to a narrower range of cells. Researchers study how to guide these cells to replace or repair damaged tissues, which is the essence of this field. The other terms refer to different ideas: immunotherapies work with the immune system to fight disease, gene therapy alters genetic material to treat conditions, and immunizations are vaccines that prevent disease.
