Research on Cells

Introduction

During this web quest we researched and answered different question about cells. We will also be talking about all of the different ways cells can help humans and there body. 

Task

In this web quest we had to find information on cells, answers questions about cells, and make a summary of all the information we have found. The purpose of this summary is to write about a scientific topic using a style suited for posting on a Web site and include information that we already knew about cells into the information we researched about cells. 

Process

  1. Many people are concerned about memory issues as they become older. Gary Small offers reassurance as well as a plan for monitoring age-related memory decline and safeguarding brain health. Patients are becoming more concerned about their usual, age-related memory problems as doctors and scientists pay more attention to Alzheimer's disease and associated dementias. When the findings of new research on early diagnosis and prevention reach a wider audience, our patients frequently ask us what they can do to keep their memory capacities as they age.







 

  1. Scientists had previously succeeded in transforming human fat cells into cells of the same general category and embryonic origin, namely muscle, cartilage, and other fat cells. According to a promising new study, mature fat cells aided mice in recovering from spinal cord injuries. They could be used in cell replacement therapy to treat central nervous system disorders in humans. Animal tests confirmed that the injected cells survived without the use of immunosuppressant drugs and that the DFAT-grafted animals had significantly better motor function than controls, according to Ohta and colleagues.

 

  1. Adult human cells can be rejuvenated by immature frog eggs. Molecules in the amphibian nucleus coax mature human and mouse DNA back into a flexible, stem-cell-like state1. John Gurdon and his Cambridge University colleagues seek to isolate the molecules responsible and utilize them to reprogram regular adult cells, such as those found in the skin or blood. This would result in an endless supply of donor-matched stem cells, which might be used to repair damaged tissue in disorders like Parkinson's and multiple sclerosis.

 

  1. Simple words:  A type of glial cell of the peripheral nervous system that helps separate and insulate nerve cells. More explanatory: Schwann cell, also called neurilemma cell, any of the cells in the peripheral nervous system that produce the myelin sheath around neuronal axons. he absence of Schwann cells can lead to the degeneration of neurons, which, in turn, is related to conditions such as MS, amyotrophic lateral sclerosis (ALS), Alzheimer's disease, and schzophrenia.The study investigated the role of Schwann cells in nerve maintenance by examining the cell’s protective features in neuromuscular junctions, which are synapses between motor neurons and muscle fibers. Researchers found that a mouse model with a mutated and dysfunctional variant of diaphragmatic erbB3— a gene required for Schwann cell development — showed degeneration of neuromuscular junction synapses and motor neurons (neurons associated with the motor-cortex, brainstem, or spinal cord) in the diaphragm.

  1.  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. The stomach wall secretes enzymes, which are part of the digestive juices, from glands that lack a mucus barrier. The enzymes are created in an inactive form, called zymogens, to avoid the cells that make the enzymes from being digested throughout the process. The enzymes are activated by other secretions and can begin digestion of the food in the stomach only when they pass through the mucus barrier lining the stomach and reach the stomach proper.

Evaluation

Task 1.The task was

 not completed. 

2. It appears thatsome effort was

made to

complete the

task, but

important

information is

missing.

3. The task was

completed as

assigned, but

some of the

information

was faulty.

4. The task was

completed with

great attention

to detail. All the

information was

reported and is

accurate.

Conclusion

In the web quest we have found lots of information on cells and how they are being used. We also researched and found answers for the questions 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?How might fat cells be able to help people with spinal cord injuries? How are frog eggs being used in research involving human cells?  What are Schwann cells? How are they affected in multiple sclerosis patients?  What role do cells play in preventing the stomach from digesting itself? During this project we have learned very much about cells.
