Across
- 5. Some adult cells are so complex and highly differentiated (often because they have fused with other cells) that they cannot divide to replenish damaged tissue and these are called:
- 7. this is when a cell becomes highly specialised with specific form and function
- 8. This is the name of cells which divide rapidly and complete a cycle of cell division (G1-->M) every 16-24 h.
- 9. Cells which are in G0 phase but when stimulated can re-enter the cell cycle and divide are called:
- 13. These abnormal cells are immortal can divide indefinitely
- 14. This is when cells divide to increase cell number and increase the size of tissue as an adaptive response
- 16. Cell death in tissues which cannot replace lost static (terminally differentiated) cells this type of loss results in _________ cellular atrophy
- 17. This is an reversible adaptive response and is an acquired change in differentiation status
Down
- 1. The process of maturation of the progenitor cells to replace the functional cells of the tissue is called:
- 2. Proliferating progenitor cells do not have an infinite capacity to divide. As the cells reach the limit (50-60 cell divisions) they then become:
- 3. This is the only possible adaptive response for static cells to increase size of tissue
- 4. Adult stem cells can self renew via mitosis but these cells are usually not in cell cycle, this non-dividing "resting' status is referred to as:
- 6. This is the failure of a tissue to reach normal size during development
- 7. This is a consequence of abnormal differentiation and abnormal cell-to-cell communication, these labile cells however can only replicate a finite number of times
- 10. The proliferating daughter cells produced from stem cells are called:
- 11. Stable cells which provide the key function in a tissue are called:
- 12. This process is used to selectively delete cells to decrease cell number as an adaptation to decreased functional requirements
- 15. Proliferation of these daughter cells can increase the number of cells in adult tissues to replenish lost cells. This amplification process leads to:
