Stem-Cell Research - Term Paper ExampleThe practical use of blood still hunt use has been in existence for over 40 years with many clinical trials using tissue derived bowknot cells (Hug, 2010 104)Today stem cell research has highly-developed into one of the most promising and influential fields of medical science. The nature of its experiments and methods, as well as the results, has also made it easily the most controversial. Its connecter with cloning has opened it up to attacks from religious groups and with many believing that the science aims at enabling humans to play god. Stem cells are cells with the ability to award indefinitely and result in a variety of specialized cells in a process known as developmental plasticity. This ability is common in embryonic cells, and they give the cells the highest potential for growth. Moreover, stem cells stub be categorized into three different groups based on their differential abilities. Namely, embryonic, adult, and foetal stem ce lls, it is worthy noting that adult stem cells relieve oneself only new-madely come to be discovered since the presupposition was they rarely contain stem cells, this has been proved wrong by recent research . Tominipotent cells are to be found in exclusively in early embryos from an individual cell in this category, a complete organism deal be formed. On the another(prenominal) hand, pluripotent cells exist as undifferentiated in blastocyst (Popular issues 2012). ... Embryonic Stem Cells One of the distinguishing characteristics of the embryonic stem cell is that it apprize transform into any other cell ranging from brain to liver cells. The chief source of these cells is the fertilized eggs from couples who are going through the In Vitro Fertilization. The 5 to 6 days old pluripotent embryos can differentiate into any one of the three germ layers (Appasani, 2010 pg 182) After the separation of the stem cells, replication of stem cell into stem cell lines follow that is a ted ious process which does not guarantee results. Replication of stem cell lines may go on in goal dishes countless times and through a period of many years. Adult Stem Cells These can be found in both children and adults with the name vista them apart from the other kinds of stem cells. Adult stem cells are evident in human beings, but the process of their isolation and identification is what tasks specialists in this field. Consequently, the in that respect is no clear cut information on whether they have restrictions to a variety of cells in relation to single tissue type or if they can exist as any tissue type (University of Edinburg Para 6). Foetal Stem Cells Unlike the other cell types, the foetal stem is easier to collect and have a lower likelihood of rejection (University of Edinburg Para 9). They are collected from aborted fetuses, the umbilical cord, or the placenta, however, Albeit considerably differentiated they still have the potential to morph into other cell types m aking them excellent for transplant. However, the downside of these is that they can transmit condition such as leukemia that may not have been detected in the fetus. Besides, there is a plethora of moral and ethical issues, bearing in mind
