Human Aborted Embryos of stem cells referred to here-in other words, cells embryos have been time and again taken from aborted fetuses. And because the last three years, research on Aborted Embryos has become one of the most promising of the entire medical sector: here, in these cells, sleeping may be the solution to many problems of transplantation of organs, and degenerative diseases like Alzheimer's or Parkinson's. The embryo, in the words of Liberation, is proving to be a "raw material" of choice.
Because stem cells have the characteristic during the first phase of the embryo, for not having yet become specialized. The researchers are working on what is to come then to control them, to tell these cells: you, you will become a lung, you, a spleen, you, a kidney, you, the brain tissue, we Then we will use to fight AD in this gentleman.
Many laboratories, therefore, feel the hot soup, and think themselves entitled to go to the most urgent, perhaps hoping to demonstrate to politicians the importance of continuing research on embryo cells.
But between the use of embryos or aborted "supernumerary" (in fertility clinics, it produces more than less, in case it would not work the first time), and the use of an embryo "created" specifically for us to take him his cell, there is a large margin psychological, that this clinical Virginia became the first to cross the world-at least, the first to be recognized. People from the Jones Institute for Reproductive Medicine, part of the Medical School of Virginia, defended themselves by claiming they had consulted members of the clergy, ethicists, lawyers and other experts on the possibility of creating these embryos as raw material for stem cells. The ethics committee of the Institute concluded the consultations that "the creation of embryos for research purposes was justifiable and it is our duty to humanity to provide a better understanding of early stages of human development.” This development is also part of the official announcement published in the July issue of the journal Fertility and Sterility.
Stem cells are the precursors of all cells of the human body. What makes stem cells so special is that they are regenerative and malleable. They have the ability to reproduce and to repair or replace other tissues of the human body. Some tissues such as skin must constantly renew itself, which would not occur without the stem cells of the skin. Other stem cells repair damage to body tissues, for example, rebuilding of damaged muscle tissue or degeneration. Recent research indicates that the malfunction or damage to stem cells may be responsible for some cancers and even muscle degenerative diseases such as muscular dystrophy. Research on stem cell function is an essential component for the discovery of treatments for these diseases and other diseases (Kathryn, 2001).
Stem cells have two important characteristics that differentiate them from other cell types. First, as noted above, all stem cells are unspecialized, and renew themselves for long periods through cell division. Then when they get biochemical signals, they can differentiate (see ...
