B2 Stem Cells HW Q1. The diagram shows one way that stem cells can be produced from human embryos. Sue Medaris/University of Wisconsin-Madison (a) Stem cells can be used to treat a condition such as paralysis. Explain why. stem cells can differntiate to become any type of body cell so they could be used to replace the damaged nerve cells‚ (2) (b) During pregnancy‚ an umbilical cord and a placenta join the embryo to the mother. At birth the umbilical cord is cut. Stem cells can

Stem Cells: The Lethal Lifesaver Stem Cells are the first cells that begin a human life‚ but some people have a problem with using them because of where they come from. So‚ the question is which is more important‚ the death of embryos or the saving of lives? Stem cells are the cells that can be whatever they need to‚ depending on what is needed. The Webster dictionary defines a stem cell as “An unspecialized cell that gives rise to differentiated cells.”. These cells have the potential to save thousands

Stem Cell Research Benefiting Alzheimer’s Somatic stem cells viable option for permanent cure. Abstract Alzheimer’s is a dangerous disease that has been troubling the citizens of the United States of America. Approximately‚ 5 million Americans of all ages have developed this disease; but most of the people affected are above the age of 65. Alzheimer’s affects the nervous system; this neurodegenerative disease tends to occur when nerve cells in the brain slowly start to die.

The Importance of Stem Cell Research Over the last decade the use of stem cells has been a controversial and heated topic. Debates have exploded over every aspect of stem cell research in nearly every region of the world. It has been speculated by scientists that stem cell research may have the power to potentially cure incredibly harmful diseases or even regrown organs. However some find that the health issues seen in earlier attempts to use stem cell transplants and ethical controversies involved

what a stem cell is. There is a lack of health literacy in our nation. So the public can’t really get into this dialogue because they don’t understand the complexity of stem cells‚ not the faith based approach‚ not the ideological or political‚ but the science behind stem cells.” Stem cells have the unique ability to transform themselves into whatever type of cells that are needed. They can be the cure for cancer‚ repairing tissue and treating diseases. As we discuss this topic of stem cell research

Embryonic stem cells The term "stem cell" in Websters dictionary defines it as "An unspecialized cell that gives rise to differentiated cells"‚ which is a fancy way of saying "stem cells can be used to copy and turn into any other type of cell". To understand Embryonic stem cells‚ we must go back to the Discovery of stem cells in general. Stem cell research first dates back to the late 1800’s‚ when scientist first observed evidence of cells able to produce other cell types. There was a gap in

Pg i Stem Cell Technology: The Controversies surrounding Stem Cell Research Introduction Whether you are in favor of or against certain forms of stem cell research‚ it cannot be denied that an immense amount of benefits are gained from the research. The extent of this research is endless. Scientists are only beginning to explore this technology. However‚ no research or medical technology is without controversy. Most of the debate falls between the embryonic stem (ESC) and

Medical Issues- Stem Cells Click on The Nature of Stem Cells to answer the following questions. 1.) Compare a stem cell and a specialized cell. Specialized cells carry out specific functions. These specialized cells are called differentiated cells. On the other hand‚ a stem cell is undifferentiated. Its role in the body is not yet determined. A stem cell can give rise to multiple cell types‚ including many stem cells. 2.) Describe a blastocyst. The blastocyst looks like a lopsided hollow ball

Issues Of Stem Cell Research When it comes to great controversial debates Stem Cell Research is one of the first that comes to my mind. It involves concerning issues that many Americans today argue that have positive or destructive outcomes. It’s a touchy subject but one that must be addressed if it is to be accepted by all those around us. Just like abortion Stem Cell Research causes sides to be divided‚ but before we can begin to argue both sides of this difficult debate we must first realize
