Stem Cells

3. adult cells that have been reprogrammed to exhibit pluripotent characteristics.
7. Stem cells derived from the inner cell mass of a blastocyst
11. Capable of differentiating into many different cell types.
14. A molecule that directs stem cells to become specific cell types during differentiation.
17. One of the primary layers of cells in the early embryo that gives rise to various tissues and organs.
18. The gel-like substance within a cell that contains various organelles.
19. The ability to develop into any type of cell.
20. A tumor containing various types of tissue, often derived from pluripotent cells.

1. A partially differentiated cell that can give rise to specific cell types.
2. The reversal of a cells differentiation status to a less specialized state.
4. The process by which stem cells develop into specialized cell types.
5. Related to the formation of blood cells.
6. Can differentiate into a limited number of cell types.
8. The outermost of the three primary germ layers, giving rise to skin and the nervous system.
9. The conversion of one specialized cell type into another.
10. Pertaining to the body's non-reproductive cells.
12. The process of renewal and growth that repairs or replaces damaged or lost cells or tissues.
13. Stem cells found in various tissues that can differentiate into several cell types, such as bone, fat, and cartilage.
15. The innermost of the three primary germ layers, giving rise to internal organs.
16. An early stage of embryonic development characterized by a hollow sphere of cells.
