skin cells when needed . Stem cells are characterized by their ability to divide itself to renew and also divide to form different types of cells‚ for example‚ the stem cells of the skin can configure the stem cells of the skin and also specialized cells make specific function such as the formation of melanin. Why stem cells are important for our health? When we are sick or exposed to the injury of our cells are also damaged or

Stem Cell Research: A Moral and Ethical Debate Stem Cell Research A Moral and Ethical Debate Imagine your life at the age of 32. It is as perfect as you could have ever imagined it. You are married with three beautiful children; two girls and a boy. Your oldest daughter is complaining of stumbling and clumsiness‚ so you take her to the doctor. You are devastated to learn that she‚ along with your other two children‚ have a neurological disorder called Batten Disease. This is a rare

Should Embryonic Stem-Cell Research Be Banned? In recent times‚ there is a great deal of controversy surrounding stem-cell research. Some say that it will contribute substantially in curing diseases like cancer‚ Parkinson’s‚ Lou-Gehrig’s‚ etc while others claim that it violates the ethical and moral norms and principles of the society. Bills promoting stem-cell research have been vetoed several times‚ making it a political issue as well. However‚ stem-cell research should not be banned because

Stem Cell Research Stem cell research has always been a controversial subject and will always be debated. The idea of taking a stem cell out of a baby that has not been born yet‚ and put in somebody else to save their life seems morally wrong to some people. Other people us playing god and altering his work to perfect our selves. But there are people that look at it and say is it both a miracle of science and see the future brighter than they did because of it. Stem cell research was started in

Embryonic Stem Cell Research is an important process that is already allowing scientists to test new drugs and figure out the cause of birth defects. The process is very delicate because scientists must work with a four to ten day old blastocyst to get the stem cells. They put the stem cells into a petri dish along with proteins and enzymes. The stew of cells‚ enzymes‚ and proteins is what helps regenerate the bad tissues that cause diseases. “Blastocysts can also potentially be created from a donor

between embryonic stem cells and adult stem cells is that the embryonic stem cells are pluripotent stem cells that are from the inner cell mass of the blastocyst. Adult stem cells are undifferentiated cells and are found throughout the body. The adult stem cells are multiplied by cell division to replenish dying cells and revitalize damaged tissues. Totipotent cells are stem cells that are capable of giving rise to any type of cell or a full embryo. A pluripotent cell is a stem cell that can give

What are the arguments for and against the use of stem cells in medicine? Stem cells – often referred to as “the building blocks of the human body” are like the basic ingredient needed in order to create a human being. This is why large amounts of stem cells can be found in early stage embryos in comparison to the adult human body where there are not as many present. Stem cells are “unspecialized” cells which have the potential to produce different types of specialist cells such as brain‚ muscle

Are stem cells important to medical research? The most basic cells in the human body are stem cells and people are formed from stem cells. Stem cells are an important part of human medical research‚ and they help with specific medical treatments. However‚ with all the good from stem cells‚ controversy surrounds the methods employed to obtain stem cells. Even with all the controversy‚ stem cells are useful. Stem cells are the most basic‚ but useful cells in the human body. They are the building
