Review of Research Paper on Creating Home-Made Stem Cells

Our news report discusses an important step in the research surrounding stubble prison cells. Pluripotent stubble cells are found in the early blastocyst, and open fire contrastingiate into different cell types such as neurons, cardiac muscle, or blood cells.As is explained elsewhere on this paper, stem cells are extremely useful and nab amazing medical potential, especially to grow specific cells, tissues, and even organs for patients. Controversy mires the progress of stem cell research from embryos, however, and technical problems personify along with the ethical ones. Marius Wernig and his team of scientists have had success studying a way to get around this, however. What if, instead of taking stem cells from fresh created embryos, an individuals own cells could be used? The cells in the braggy body are no longer stem cells they arent pluripotent, and can only be a certain type. But with special techniques, its actually possible to induce these adult c ells to convey stem cells, with a pluripotency that allows them to develop into whatever cell type is needed In this experiment, bring on pluripotent stem cells were created using the fibroblast cells from mice. Fibroblasts were removed from underneath the skin of the subject mice. In order to revert the cell back to a induced pluripotent state, quartette specially selected transcription factors (Oct 4, Sox 2, c-Myc and Klf4) were used. These four transcription factors were each incorporated into the desoxyribonucleic acid of a virus that lacked the capacity to infect, and the fibroblasts were exposed to these viruses. Just like regular viruses, these injected their DNA into the fibroblast cells, and the DNA was incorporated into the cell. Now the fibroblasts contained the new transcription ... ... turn a breeding ground for debate as well as a popular platform for presidential candidates. These topics have also become very partisan issues, Democrats being known to fully support stem cell research and Republicans being known to disagree with the practices involved with it. In 2004, stem cell research was a particularly hot topic, and it is commonly thought that President Bushs second term was won that year due to his stance on embryotic stem cell research. He thought is was unethical to create any more embryonic stem cell lines, but that the use of the existing ones for research was acceptable. plant Cited Wernig, Marius, Alexander Meissner, Ruth Foreman, Tobias Brambrink, Manching Ku, Konrad Hochedlinger, Bradley E.
