Stem cells are "blank" cells that have the potential to develop into any type of cell in the body -- nerve cells‚ heart cells‚ kidney cells. Scientists are trying to harvest the cells before they have differentiated‚ then coax them into becoming certain types. If they could grow cardiac cells‚ for instance‚ scientists one day might be able to replace damaged heart tissue in someone who has had a heart attack. By growing nerve cells they might be able to repair brain cells damaged by Alzheimer’s or

Rebecca Harris Mrs. Ruth English 12 Honors 12 March 2013 Embryonic Stem Cell Research Embryonic Stem cell research is it an ethical issue or medical miracle? Embryonic stem cell research is a method of retrieving the inner cells from a fetus (Korenman). The main issues with embryonic stem cells are where they come from‚ the ethical issues‚ what they can do‚ and the treatments used with them. Because of the advances Embryonic Stem Cell Research has made in cancer‚ blood disorders‚ and other diseases

Why reject it? Stem cell research has been in the media since the day it was discovered. With the potential to cure many patients who are otherwise bound to die of diseases that are currently incurable‚ of course stem cells would be a big deal. But there are people who believe that stem cell research is a very inhuman and immoral act only because embryonic stem cells come from unborn embryos. Even within developed nations‚ research of stem cells is illegal because of this. These nations ignore

The General topic of this political cartoon is that Mr. George W. Bush refuses to allow stem research to take place because he feels it kills “babies” since it is done on embryoinic cells. On the other hand he is “killing” Iraqie civilians in the war‚ and it is “ok” to do that. Messages included in this cartoon is “ It’s unethical to spend Taxpayer dollars to destroy human embryos.”‚ “Human beings- ok”‚ and “Stem cell research veto”. The character in this cartoon is Mr. Goerge W. Bush‚ he was a

Fetal tissue research is an important aspect of medical research. Fetal tissues can be obtained from many places‚ including hospitals‚ tissue banks‚ and abortion clinics. Conducting fetal tissue research allows us to further our education concerning diseases‚ vaccinations‚ and birth defects. Despite the importance of fetal tissue research‚ it raises many controversies regarding ethical issues. Many people believe that fetal tissue research should be illegal because it goes against their morals

Procedure Twelve zebra finches were separated into three rearing conditions 4-5 days after hatching. Four zebra finches with an equal distribution in gender were randomly assigned to the three different rearing conditions; biparentally reared‚ maternally deprived‚ or paternally deprived. For the following 115 days‚ the interactions between parental and offspring behaviour was recorded. On PHD 30‚ 90‚ and 120‚ baseline blood samples were taken within five minutes of entering the laboratory room. Corticosterone

Stem cells are primitive cells found in embryos‚ fetuses‚ and recently adults that can grow into 210 types of cells in the body. James A. Thomson‚ an embryologist at the University of Wisconsin‚ and John D. Gearhart of the Johns Hopkins University School of Medicine announced on Thursday‚ November 8 1998 that they and their colleagues had isolated the cell. Scientists have tried for years to find stem cells because of their great medical value. Diseases such as Diabetes‚ Bone Marrow Cancer‚ Chronic

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

With nearly 3‚800 species‚ lizards are a widespread group of squamate reptiles. Some of these creatures are capable of autotomy‚ which allows them to detach their tail and later regenerate a new one. This is most commonly used as a predator defense mechanism. The African house gecko‚ Hemidactylus Mabouia‚ is one of the limited species of reptiles that are able to reproduce a lost limb. Autotomy and tail regeneration can be broken down to several steps‚ from the severing of the old tail to the three

Stem Cell Research NAME American Military University Abstract This Paper explores the fine lines of study regarding Stem Cell Research. We’ll discuss the Stem Cell basics to include the importance for use‚ the effects of repairing the body‚ and the possible benefits to curing diseases and illnesses. As well shed light on the Ethics regarding the use of Stem Cells. To include but not limited to the debate regarding the procedure is immorally wrong (ethically speaking)‚ the death of
