Stem Cell Research Under Fire

Stem cell research in fires Stem cell research should continue curing the most serious diseases in the world in the world such as Alzheimer's disease, heart disease, Parkinson's disease, diabetes etc. in a day. Stem cells are taken from human embryos, placed in a petri dish, scientists can manipulate them to produce any desired cells (Blumenstyk, 2004). Stem cells can be used for the regeneration of bones, organs and tissues, and it is also useful for treating the above diseases. Many universities such as Vanderbilt and Case Western participated in this study for two main reasons.

Stem cells grow in a laboratory petri dish and are not transplanted into a woman's uterus. These cells can be used to generate stem cell lines that can grow indefinitely under optimal conditions ("Stem Cells and Diseases", 2011). Embryonic stem cells can be derived from existing stem cell lines (any set of cells from the same original embryo), aborted or aborted embryos, unused in vitro fertilized embryos, and clonal embryos produced from somatic cell nuclear transfer (from unfertilized) . The egg is replaced with the nucleus of the adult stem cell This technique is used for therapeutic cloning, which will be the growth organs and skin grafts of the patient, but prior to 2001 only federal government funded research Was done. Several embryonic stem cell lines made using embryos (Dunn, 2005; Embryo and Fetal Research Methods, 2008; Therapeutic Cloning, 2009)

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 grow. These stem cells are more readily available than adult stem cells because they are obtained when the inner cell mass is concentrated in the embryo 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
