The majority of the stem cells being researched are being interpreted from the body and give favorable outcomes, embryonic stem cells however, do not. They are wide rejected by the body and do not notice once injecte d into the tar compensate site. in that location is no use squander money with these cells if there they are not producing especially when there are other types of cells that give up similar characteristics. Therefore embryonic stem cells should not be used because of the controversies and ineffectiveness and cerebrate should be directed more on other types of stem cell research for medicative purposes.
The human body maintains an great amount of stem cells that are used on a daily basis. Since there are so many types of cells, a general definition should original be given. A stem cell is defined as cells that obtain the capacity to self-renew as well as the ! loudness to generate variediated cells (Kelly 4). This ability to reproduce and differentiate into different tissues is the key factor of it. not all stem cells have the ability to produce any kind of tissue though. totipotent stem cells are the most versatile type of cells and are able to differentiate into all types of tissues including an organism. Pluripotent stem cells are very similar to totipotent ones in their characteristics but are unable(p) to develop into entire...If you want to get a full essay, ready it on our website: OrderCustomPaper.com
