Across
- 2. The process by which cells become increasingly specialized to carry out specific functions in tissues and organs.
- 4. A person with advanced knowledge of empirical fields.
- 9. A group of cells with a similar function or embryological origin. Tissues organize further to become organs.
- 10. A cluster of dividing cells made by a fertilized egg.
- 12. Tissue or cells obtained from a dead human embryo or fetus after a spontaneous or induced abortion or stillbirth.
- 15. A group or layer of cells that work together to perform a specific function.
- 17. Cells with the potential to develop into many different types of cells in the body.
- 18. A permanent change in gene expression inherited by all of a cell's descendants
- 19. Adult stem cells, present in skeletal muscle tissue, which can self-renew and are capable of giving rise to skeletal muscle cells.
- 20. An immature cell that can develop into all types of blood cells, including white blood cells, red blood cells, and platelets.
Down
- 1. Largely undifferentiated cell originating in the central nervous system.
- 3. Promotes the repair response of diseased, dysfunctional or injured tissue using stem cells or their derivatives.
- 5. These stem cells come from embryos that are 3 to 5 days old.
- 6. An animal in the early stages of growth and differentiation that are characterized by cleavage, the laying down of fundamental tissues, and the formation of primitive organs and organ systems.
- 7. Any of the 3 layers of cells differentiated in embryos following gastrulation.
- 8. An impairment of health.
- 11. The basic structural and functional unit of all organisms
- 13. Early stage cells that can become any type of cell in the body.
- 14. Unspecialized or undifferentiated cells.
- 16. A single cell that forms when an egg is fertilized by a sperm. Every cell type in the human body arises from this single cell. Within a few days, that single cell divides over and over again until it forms a blastocyte.
