1. Impact of Research in Cell Biology

2. What are 5 examples of research projects in cell biology?
Stop development of cancers
Regenerate nerve cells to repair spinal cord injuries
Develop vaccines to prevent diseases
Prepare to stop the spread of infectious diseases not known yet
Increase world food production
Discover biological tools to clean up pollution

3. What is the relationship between cancerous cells and a tumor?
Cancer is a disease related to the uncontrolled and rapid reproduction of cells through cell division
Cancerous cells continue to reproduce instead of carrying out their function
This results in a tumour
A tumour is a mass of cells that keep dividing

4. What is cell researchers goal?
How to turn off non-stop reproduction of cancer cells
How to destroy tumors
Find out why the process begins

5. Repairing Damaged Nerve Cells
The spinal cord is like a highway of messages
Damage in the spinal cord that severs it can result in a loss of information from the senses and instructing muscles to move
Paralysis is the inability to move

6. Helping People with Spinal Injuries
We have many ways to make people with paralysis better lives: wheelchairs, access
Cell Biologists are working on regenerating the damaged cells
Working towards finding ways to trigger the cells to repair themselves

7. Preparing for Infectious Diseases
We understand and have stopped the spread of diseases like smallpox, polio, measles, TB
New bacteria and viruses adapt to create new diseases
Researches study how diseases are transmitted to other people

8. Stopping the Spread of Infectious Diseases
Before cell biology (microscopes) scientists knew that disease could be transmitted through physical contact
Quarantines are enforced periods of isolation for individuals exposed to an illness
Should people in the area where the new disease has been found be allowed to leave?

9. Improving World Food Production
Cell biologists change plants so they can grow in different conditions
Modify plant cells to improve resistance to insects and chemicals
Change plants to increase their nutritional value – e.g. inserting genes from beans to rice to increase iron
Controversial – many people do not like this branch of cell biology
