Across
- 1. process where immature, unspecialized cells develop into mature cells with specific functions
- 3. stem cell that gives rise to multiple cells within a lineage; limited to the cell types found in the tissue of specific origin
- 6. the middle germ layer; develops into several different vital tissues and organs
- 9. these layers arise early in embryonic development to give rise to all organs and tissues in animals
- 10. derive from the inner mass of very early embryos (blastocyst)and have the potential to differentiate into almost any cell in the body
- 11. the most potent type of stem cell that can differentiate into any cell in the human body
- 12. certain genes are turned "on" or "off" to produce different proteins, leading to specialized cell types
- 13. a special type of unspecialized cell that is able to renew itself and differentiate into different types of cells
- 15. found in bone marrow; can differentiate into various types of blood cells
Down
- 2. adult cells that have been reprogrammed to behave like embryonic stem cells
- 4. a stem cell that can differentiate into any of the three germ layers
- 5. the outermost germ layer; develops into the epidermis and nerve tissue
- 7. the region where plant stem cells are found
- 8. the innermost germ layer; develops into the gut lining and associated tissues
- 14. can become bone, cartilage, and fat cells
