Introduction Human embryonic stem cells (hES cells) are currently discussed not only by the biologists by whom they were discovered but also by the medical profession‚ media‚ ethicists‚ governments and politicians. There are several reasons for this. On the one hand‚ these ‘super cells’ have a major clinical potential in tissue repair‚ with their proponents believing that they represent the future relief or cure of a wide range of common disabilities; replacement of defective cells in a patient by transplantation

difference between embryonic stem cells and adult stem cells is that an embryonic stem cell is not fully developed and with no specific cell tissues. Embryonic stem cells are found in the inner cells mass of the early embryo. The very first embryonic stem cells are totipotent (can be able to create all kinds of cells) but the rest after that are pluripotent which means that it can create many different types of cells such as white blood cells‚ nerve cells‚ and neurons. Adult stem cells are less flexible

Embryonic stem cells help treat tough diseases that our bodies attracted‚ and can not fight off. If we continue to use embryonic stem cells then the treatment for these tough diseases will be more efficient. “ Stem cells are expected to be most useful in treating tough diseases.(those that arise from problems with various genes‚ and are often related to environmental causes)” (Pearson). This information is saying that embryonic stem cells are more useful than any other stem cells because they are

fertilized egg cell divides millions of times to form the approximately six billion cells that make up the human body. These types of cells (4 to 7 day old embryo) are called embryonic stem cells that are unspecialized and have the ability to renew themselves and give rise to specialized cell types (they have not yet developed into cells that perform a specific function). A stem cell is uncommitted and remains that way‚ until it receives a signal to develop into a specialized cell‚ unlike a heart

One of the most controversial debates in recent history has been the human embryonic stem cell debate. Millions and millions of embryos are not used each year when they could very well lead to a cure for fatal diseases such as leukemia and cancer. As well as become a cure for neurological diseases like Alzheimer’s disease and Parkinson’s disease. Human embryonic stem cell research has enormous potential to cure many diseases and change the face of modern medicine. However‚ there is much debate

One of the recent biomedical research is “Human Stem Cell” from which all 210 different kinds of tissue in the human body originate(the Center for Bioethics and Human Dignity‚ 94). Additionally‚ UNESCO states that separating some inner cell mass from the embryo at the blastocyst stage‚ they can be cultured to produce pluripotent stem cells‚ capable of developing into blood ‚ muscle‚ or many other kinds of tissues and organs of the body (13). Thus‚ at first “Stem Cell” may sound

Embryonic cells are able to grow into all derivatives of these primary germ layers ectoderm‚ endoderm‚ and mesoderm. Embryonic stem cell research would be a good thing for humans because human embryos for stem cell research can help a number of patients‚ they can be used by scientists to find cure for several medical conditions‚ and the stem cell research may be a treatment

debated whether embryonic stem cell research is necessary to human life. The heated topic has many pros and cons on each side. I believe that embryonic stem cell research could be beneficial if used for the right reasons and by the right people. Some say that the research will conflict with ethical‚ moral‚ and political views. Stem cells are nonspecialized cells that can create other types of specific cells. These cells serve as a repair system inside of many tissues. The cells divide with no limit

Biology 103 Stem cells are known as the foundation of our bodies‚ and without them we would be unable to repair various organs or tissues whenever they may become damaged. Stem cells are very extraordinary cells because after division and a new cell is created‚ they are able to either remain a stem cell or turn into an even more specialized cell such as a muscle cell‚ red blood cell‚ or brain cell. Until recently‚ there were only two major types of stem cells‚ known as embryonic stem cells and adult
