Introduction
Cells are microscopic units of life that help people in countless ways. In this presentation, I will be going over the different ways cells can help people.
Task
Cells are the smallest unit of life, but not the smallest unit of matter. Humans have trillions of cells, and we're going to learn how they work together.
Process
-
Blood flows less fast as your age increases, which can lead to less blood getting to the brain. This means that the brain will process information more slowly and likely cause memory loss, either long term or short term. Scientists were able to reverse memory loss by giving a mouse a “viral vector”, a virus capable of restoring the amount of 6-sulphate chondroitin sulphates in the perineuronal nets.
-
Fat cells can turn into nerve cells for a short amount of time. During this period, the nerve cells can be used to repair or fix the spinal cord, and other injuries that would need a replaced nerve cell.
-
By putting a white blood cell’s nuclei into a frog egg molecule, it can turn into a stem cell. The stem cells can reprogram the adult’s cells and rejuvenate them.
-
A schwann cell is one of the cells in the peripheral nervous system that produces the myelin sheath.
-
The stomach is protected by its epithelial cells. The epithelial cells coat the mucosa with a bicarbonate-rich solution, which prevents autodigestion (the stomach digesting itself).
Evaluation
Summary:
Scientists figured out how to revert memory loss in mice by giving them a "viral vector". Fat cells can be used to repair the spinal cord and other related injuries. Frog eggs could create stem cells that can rejuvenate adult cells. The reason the stomach doesn't digest itself is because of the epithelial cells creating a bicarbonate-rich solution.
Conclusion
To conclude, we went over some of the ways that cells can protect and help your body. This includes autodigestion protection and fat cells replacing the spinal cord.
