  1. What Are Stem Cells?

  2. Stem cells are special human cells that are able to develop into many different cell types. • This can range from muscle cells to brain cells. • In some cases, they can also fix damaged tissues. • Researchers believe that stem cell-based therapies may one day be used to treat serious illnesses such as paralysis and Alzheimer disease.

  3. Types of stem cells

  4. Embryonic stem cells • The embryonic stem cells used in research today come from unused embryos. • These result from an in vitro fertilization procedure. • They are donated to science. • These embryonic stem cells are pluripotent. • This means that they can turn into more than one type of cell.

  5. Adult stem cells.

  6. Adult stem cells.

  7. Stem cells in medicine • The only stem cells now used to treat disease are hematopoietic stem cells. • These are the blood cell-forming adult stem cells found in bone marrow. • Every type of blood cell in the bone marrow starts as a stem cell. • Stem cells are immature cells that are able to make other blood cells that mature and function as needed.
