All types of cells

Introduction

Research on cells has gone a long way. Cells provide structure and function for all living things. A human is made up of trillions of tiny cells. Cells work together to make your body function. When cells connect with each other in a group they form into tissue. Tissue formed together is called an organ. Cells have many parts; each part has a different function. Some of these parts are called organelles and they are specialized structures that perform certain tasks within the cell

Task

i will be talking about cells and how scientists experiment with them. i will also be answering 5 questions about cells:

 

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?

2. How might fat cells be able to help people with spinal cord injuries?

3. How are frog eggs being used in research involving human cells?

4. What are Schwann cells? How are they affected in multiple sclerosis

patients?

5. What role do cells play in preventing the stomach from digesting itself?

 

 

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 protect and repair brain cells and stimulate neural growth decline with age so older people often experience decreased blood flow to the brain, which can impair memory

 

2. How might fat cells be able to help people with spinal cord injuries?

the ability to get stem cells from a patient's own fat that can help repair injury to the spinal cord, as the tissue copies the development of the spinal cord in human embryos

 

3. How are frog eggs being used in research involving human cells?

In mature frog eggs can rejuvenate adult human cells people hope to reprogram ordinary adult human to repair tissue damage in diseases

4. What are Schwann cells? How are they affected in multiple sclerosis

patients?

schwann cells are axons of peripheral neurons that are often surrounded by cells of another type, known as schwann cells.

 

5. What role do cells play in preventing the stomach from digesting itself?

The stomach does not digest itself because it is lined with epithelial cells, which produce mucus. And it  forms a barrier between the lining of the stomach and the contents.

Evaluation

cell research holds great promise for medical treatments, but scientists still have a lot to learn about cells, and the specialized cells they generate in the body and their capacity for healing 

Conclusion

Scientists are still learning about and experimenting with cells. They are investigating how to use cells to create tissue that when transported will replace damaged tissue. They are also investigating ways to encourage self-repair stem cells in the human body to make healthy cells to heal damaged cells. For example, they have learned that immature frog eggs can make adult human cells. Scientists are currently experimenting with them hoping to find out why,  and if it can be adjusted to repair human tissue damage. However, something that can help repair tissue damage is your own fat. Scientists have discovered the ability to get stem cells from a patient's own fat to help fix injuries to the spinal cord because the tissue copies the development of the spinal cord in human embryos. Scientists continue to discover and  experiment with cells and the interesting things about them. Currently they help as medical treatments and maybe in the future they will be used for other reasons that we don’t know yet. Who knows what scientists will or can discover in the future?
