Stephen Napier on Stem Cell Research

The controversy this article is analyzing is one of the major discussions of today. The focus of discussion is whether embryonic stem cells should be used to treat degenerative diseases such as Parkinson's disease, Alzheimer's disease, diabetes and so on. The writer is Stephen Napier working with Philadelphia's Bioethics Center in Pennsylvania. This article was published in Journal of Medicine and Philosophy in 2009. In this article, Mr. Napier remembered past arguments about the current debate and provided readers with his position on the use of stem cells as part of the research, he said that the position of the fetus is vulnerable and that it is moral Value to believe in existence

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

The basis of stem cell biology starts with the definition of stem cells. Roughly speaking, stem cells are two important functioning cells: 1) self replication and 2) differentiation, or conversion to other cells. Self-regeneration means that the cell divides (mitotically) and proliferates, or the number increases. Differentiation is the process by which stem cells are converted to another more specialized cell. An example of this is hematopoietic stem cells or blood stem cells found in the bone marrow, which can be increased (self-replicating) and differentiated into leukocytes to obtain an immune response (author's warning: technical The lineage is due to a group of ancestors) then enter the terminal differentiated cells)

Japanese Section 1 The term stem cell of stem cell research paper is an undifferentiated cell. In other words, it can divide and proliferate before doing special work in the body such as bone cells and skin cells. Embryonic stem cells are derived from developing embryos, adult-derived somatic stem cells, and umbilical cord blood-derived umbilical cord stem cells. (Stem cell basis, 2) Each of these stem cells can be used to treat various different diseases, but ... others. Research on the use of stem cells holds infinite possibilities in the medical field. Stem cells are cells of our original form. These cells, whether it is neural tissue or other cells, are not the cell type they are targeting. However, stem cell research is a very new field, but its progress is limited by ethical and ethical issues.
