Introduction
This webquest will take you on a journey through the world of cells and science.
Task
Let's talk about what we're going to do
This WebQuest will begin by giving us a brief review of the amazing world of cells.
Following that, we'll discover some facts regarding how these cells function.
So, let's get started.
Process
1. What do researchers think is one cause of memory impairment related to growing older? What does new research show that may be able to help reverse this process?
Hormones and proteins that maintain and repair brain cells, including those that encourage neural growth, reduce as people age. Reduced blood flow to the brain is common in older people, which can affect memory and cause mental changes.
2. How might fat cells be able to to help people with spinal cord injuries:
Scientists at Duke University Medical Center and a company called Artecel Sciences Inc. think the cells they recently "grew" out of fat tissue left over from liposuction procedures could actually be nerve cells. Basically, transplanting fat cells can promote the recovery of their hind limb function.
3. How are frog eggs being used in research involving human cells:
The researchers prepared protein extracts from frog eggs, which recapitulates the repair of the lesion in a test tube. These extracts contain the same proteins as human cells, making it a great model for studying these lesions.
4. What are Schwann cells? How are they affected in multiple sclerosis patients?
"Schwann cells are a type of non-neuronal cells that support and protect neurons in the peripheral nervous system by forming, a fatty layer that insulates nerve axons.The absence of Schwann cells can lead to the degeneration of neurons, which, is related to conditions such as MS, amyotrophic lateral sclerosis (ALS), Alzheimer’s disease, and schizophrenia."
5. What role do cells play in preventing the stomach from digesting itself?
Because the stomach is coated with epithelial cells that create mucus, it does not digest itself. This creates a barrier between the stomach lining and the contents. is coated with epithelial cells that create mucus. This creates a barrier between the stomach lining and the contents. This is the main way that your stomach protects itself from autodigestion (the stomach digesting itself) and the overall acidic environment.

Conclusion
Hormones and proteins that maintain and repair brain cells, such as those that encourage neural growth, reduce as people age. Reduced blood flow to the brain is common in older people, which can affect memory and mental changes.
Fat cells from women who have had liposuction procedures could help people with spinal cord injuries. Transplanting fat cells can promote the recovery of their hind limbs, according to a company called Artecel Sciences. The company's research is being done at Duke University Medical Center in North Carolina.
Frog eggs contain the same proteins as human cells, making them a great model for studying human cell repair and regeneration.
