Stem Cell Use and Research

The type of cells that adult stem cells can differentiate can be restricted by the original tissue, but there is evidence that it is not the case. Contrary to embryonic stem cells seen on 4 to 5 days of human embryos. Because of the lack of irritation to distinguish them, they can divide into more stem cells more rapidly and rapidly than they can be any kind of cells in the body. Finally you can stimulate them into special type of cells. It is worth noting that embryonic stem cells are harvested in a strange way.

Stem cells are "transformed from fertilized eggs to infants" (10). "In adults, replace new or damaged cells with damaged cells" (10). The stem cells used for the study are embryonic cells. "Embryonic stem cells are cells that develop in the early stages of human and animal development" (16). The use of embryonic cells has caused many controversies, especially in the United States. In 2001, President Bush implemented the rule that only 60 trunks created before August 9, 2001 can be used for stem cell research. It will be funded by the Federal Fund (Black)

In the field of stem cell research embryos and adult stem cells are often compared. The controversial use of embryonic stem cells is supported on the basis of their many advantages on adult stem cells. Embryonic stem cells are more readily available; they have greater cell proliferation, also known as proliferation, ability; and they are more versatile. Blastocyst stem cells are isolated from the embryo during the blastocyst stage and this process destroys the structure of the embryo to the extent that the embryo can no longer develop. Since these stem cells are obtained when the inner cell mass is concentrated in the embryo, they are more readily available than adult stem cells and the number of adult stem cells is limited. Another beneficial advantage of embryonic stem cells is their ability to grow and grow indefinitely when cultured under appropriate conditions (Devolder 9)

There are three types of stem cells: embryonic stem cells, adult stem cells, artificial pluripotent stem cells (iPS). The most famous type of stem cells are embryonic stem cells. This is due to the extensive coverage of such stem cells by the media and the many judiciary laws developed based on their use. Because they are the most flexible stem cell types, they are also popular among researchers. Unlike their more mature counterparts, they have the ability to regenerate all types of cells. Embryonic stem cells are found in two areas: umbilical cord and embryo. Embryonic stem cells are found in blood taken from umbilical cord immediately after birth. It contains hematopoietic stem cells that can be used to produce erythrocytes; among other things. There are also mesenchymal stem cells that can be used to grow muscle and bones. Hematopoietic cells are used for the treatment of blood related diseases such as autoimmune diseases and leukemia
