  1. 3. stem cells, which have the ability to develop into more than one cell type of the body.
  2. 4. stem cells in the gut, epidermis
  3. 5. A type of pluripotent stem cell, similar to an embryonic stem cell, formed by the introduction of certain embryonic genes
  4. 6. A fluid-filled sphere formed about 5 days after fertilization of an ovum that is made up of an outer ring of cells and inner
  5. 7. An undifferentiated cell that is capable of dividing and giving rise to one or more distinct types of specialized cells
  6. 10. Middle layer of a group of cells derived from the inner cell mass of the blastocyst
  7. 11. The manipulation of stem cell culture conditions to induce differentiation into a particular cell type
  8. 14. Stem cells that can differentiate into any type of specialised cells found in organisms of that species.
  9. 16. The cluster of cell the blastocyst. These cells give rise to the embryo and ultimately the fetus.
  10. 18. A stem cell that gives rise to all red and white blood cells and platelets
  11. 20. Stem cells, that can only become one type of cell
  12. 21. Growth of cells in vitro in an artificial medium for experimental research
  13. 26. what are the cells that are thrown out during IVF?
  14. 27. The process of activating an egg without fertilizing?
  15. 28. what might be the only totipotent?
Down
  1. 1. Lack ethical concern and potency is uncertain
  2. 2. can give rise to almost any type of cell that make up the body
  3. 5. Latin for "in glass"; in a laboratory dish or test tube; an artificial environment
  4. 8. A cell that has not yet developed into a specialized cell type.
  5. 9. Internal and external factors that control changes in cell structure and function.
  6. 12. ethically controversial and political
  7. 13. How many lines are derived from one embryo?
  8. 15. Embryonic stem cells give rise to different cell types with same DNA , but different gene expression
  9. 17. A relatively rare undifferentiated cell found in many organs and differentiated tissues with a limited capacity.
  10. 19. In humans, the developing human from approximately eight weeks after conception until the time of its birth.
  11. 22. A field of medicine devoted to treatments in which stem cells are induced to differentiate into the specific cell type.
  12. 23. where are HSCs found in the fetus?
  13. 24. In humans, the developing organism from the time of fertilization until the end of the eighth week of gestation.
  14. 25. Methods for genetic analysis of embryos
