Those who have this ideal said, "Early embryos not transplanted into the uterus do not have psychological, emotional or physical characteristics associated with humans, so we are concerned about the need for protection On the other hand, supporters of this type of research believe that "fertilized human eggs are only part of the body of others until they grow to an extent sufficient to survive independently" It is. The only respect that is caused by blastocysts is respect that is to be shown in the property of others.
As defined in "Human embryonic stem cell controversy: science, ethics, and public policy", human embryonic stem cells are "self-renewing cell lines that produce all the cells and tissues of the body" (the Netherlands 3). Most stem cells can only differentiate into a single form of progeny cells, also known as progeny cells. For example, hematopoietic stem cells are stem cells that form only blood cells, but skin stem cells can only produce skin cells. Because these stem cells are taken from postnatal patients, they are called adult stem cells or somatic stem cells (Devolder 5). At the same time, the embryonic stem cells are pluripotent, which means they have the capacity to produce all the cells and tissues of the body (Holland 5)
Human embryonic stem cells go into regenerative medicine. The use of human embryonic stem cells poses different ethical problems. Application of these cells can be applied to tissue engineering, genetic engineering and other medical research purposes. Although the use of adult stem cells is not controversial, the use of human embryonic stem cells poses different ethical issues based on cellular origin. (Hug, the source of human embryonic stem cell research, 2005)
There is extensive controversy regarding the use of human embryonic stem cells. This controversy is primarily directed to techniques for obtaining new embryonic stem cell lines that require destruction of blastocysts. The opposition to the use of human embryonic stem cells in research is usually based on philosophical, moral or religious objections. This study includes adult stem cells, amniotic stem cells, and induced pluripotent stem cells.
There are two types of stem cells. One is an embryonic stem cell and the other is an adult stem cell. How did they get it with human embryonic stem cells? Embryonic stem cells use cells derived from a single cell such as eggs, sperm, fertilized eggs. "Stem cells are cells inside human embryos. The blastocyst is the developmental stage of the formation of the inner cell mass of the embryo. The trophoblast is removed from the embryo, the inner cell mass is isolated and the embryonic stem cells are extracted from the internal mass using a micropipette. Thereafter, the material obtained from the internal material is obtained. To help transplant into tissues and fight difficult diseases, put in culture and frozen in liquid nitrogen (http://www.e-stem-cell.com). When stem cells are obtained from a living human embryo, the harvest of such cells requires destruction of the embryo.
