Research on Cells...

Introduction

Different cells play important roles for our bodies, and today in this presentation you will see different examples on how they help our bodies.



 

Task

A cell is the smallest unit of life. Large plants and animals have many billions of cells. In this web quest you will learn how cells play different roles in our bodies. There are many ways that this works, which is what this web quest presentation is for.



 

Process

  1. When you grow older you can lose some memory. You're not as quick as you were in the past but if you give yourself time, your memory and information will come back to you. Elderly people can experience less blood flow to the brain which can impair your memory. To reverse this and not lose your memory, you can do productive things while using your brain. For example, you can make a to-do list and plan your day/tasks.

 

  1. There is a new technique that would be clinically able to be done. Research has been done that if a person has a spinal cord injury you could take some of their own fat, cure and care for it and put it back in. In this study they took cells from human and mouse fat tissues, and then treated them with chemicals and growth factors and it became into something that behaves like nerve cells.

 

  1. Undeveloped frog eggs can renew adult human cells. Molecules in the amphibian nucleus coax develop human DNA back to an adjustable stem-like cell stage. Scientists from “Cambridge University” in the UK inserted immature Xenopus frog eggs with either nuclei from a mature/ adult mouse or a human's white cells.

 

  1. Schwann cells border neurons to protect the drop of nerves by stopping thrombin, a blood clotting protein that can also impair nerves. Schwann cell fat of the PNS stay normal

 

  1. The stomach does not digest itself because it is lined with epithelial cells which can produce mucus. That can form a railing so nothing can go through. This forms in the middle of the lining in the stomach and its contents.

Evaluation

Frog eggs that are not yet developed can renew human cells. Molecules in the amphibian nucleus coax develop human DNA back to an adjustable, stem-like cell. Researchers prepare protein draw out from the frog eggs, which restates the repair of the lesion in that are found in human cells, for that reason it represents a good model to study these lesions



 

Conclusion

To sum up and explain everything we have stated, different cells play important roles in our bodies by providing structure for our bodies, convert nutrients to energy and cary out specialized functions.
