Stem Cells: Are They More Than Just Cells?.
Should stem cells be considered as a life? Many religious people may think so and describe stem cell research to be immoral and wrong. Scientists believe that stem cells can lead them to cures for multifarious diseases. Some people say that stem cell research should not be done because of moral and religious reasons, but many others feel that it can lead to many cures in the future. .
Stem cells are considered the building blocks of biology. Research in developmental biology is what led to the discovery of human stem cells, precursor cells that can give rise to multiple tissue types. A stem cells comes to be when an egg is fertilized and it triggers a majestic sequence whose first step is to create a new structure that is composed if stem calls. Stem cells are capable of morphing into any component of the body such as the heart, nerves, blood, bone and muscle. The embryos of all mammals start out and a group of forty stem cells (Yount 40). The different types of stem cells are embryonic stem (ES), embryonic germ (EG), fetal stem cells, and adult stem cells. The ES and EG cells come from aborted fetuses which raise the question of whether this is moral or not, much like the controversy of abortion (American 1). .
The research and study of stem cells can lead us to many great opportunities in the future. It was thought for a long time that because stem cells are genetically programmed to be changed into other things it would be impossible to control them. In December 1998 two scientists, Gearheart and Thomson, found this to be not the case. Each of them isolated embryonic cells and induced them to begin copying themselves with out turning into anything else. In doing this they have discovered a way to make stem cells by the billions. The process is not very complicated and the stem cells can be reproduced roughly in the same way that pharmaceutical manufacturers produce drugs.
Thirty years ago they discovered the stem cell. Now, scientists are researching human stem cells. ... Stem cell research has become a very controversial issue today. ... But because of the controversies around stem cells, some people want stem cell research stopped. ... There have been many publicized events on stem cell research. ...
Many urged President Bush to agree with former President Clinton's policy on stem cell research and that was; that the Congressional ban on funding embryo research would not be broken if the support was provided for only stem cell research and not for human cloning and no embryos would be destroyed to acquire these stem cells. ... Arlen Specter, R-Pa wants funding of stem cell research without any limitations. ... Arlen is the most critical of President Bush's policy on stem cell research funding. ... Thompson argues that he did not believe that any of the stem cells were conta...
Stem Cells 1. ... Adult and cord blood stem cells can be donated. If embryonic stem cells are done through donation, then I condone them for research only. ... Stem cells are important for living organisms for many reasons. ... Unlike muscle cells, blood cells, or nerve cells " which do not normally replicate themselves " stem cells may replicate many times. ...
Stem cell research has become an issue of much debate. ... The basic ethical issue raised is related to where we obtain the stem cells. ... Stem cells can also be obtained from an adult's blood or bone marrow, but these stem cells are not as versatile and can grow only into a few select tissues, as opposed to embryonic stem cells that can grow into almost any tissue (Stem Cells: Corporate Profile). ... However, there are two conditions for my support of stem cell research. ... He announced on August 10, 2001 that some federal funding for stem cell research would be provided for ste...
Stem cell research is a controversial issue in America. Stem cells are a primitive cell that can multiply and conform to be any cells. Unfortunately, the best source for stem cells is human fetal tissues. To extract the stem cells, you will in turn, kill the embryo. ... Both of these are options for obtaining stem cells. ...
Some of the stem cells sources are adult stem cells, cord blood stem cells, embryonic stem cells, freckles that yield stem cells, and stem cells from extracted teeth. Adult stem cells, also called somatic stem cells, possess the same basic characteristics of all stem cells[Mur14]. ... The reason why we have adult stem cell in our body is to repair and maintain specific tissues adjacent to the adult stem cell. ... Embryonic stem cells are derived from embryos. As with all stem cells, embryonic stem cells are unspecialized cells that have the ability just like the adult stem cells[Mur14]. ...
Stem Cell Research, it's Past and Current Policy Stem cells are the latest controversial topic in the forefront biological research. ... Embryonic stem cells are unlike any other adult stem cells. ... Another type of stem cell that has properties similar to the embryonic stem cell is the embryonic germ cell, derived from the early stages of the developing fetus. ... This method collects embryonic stem cells. ... To create embryonic stem cells for research, a "stem cell line" must be created form the inner cell mass of a week-old embryo. ...
Recently, I have been researching the positives and negatives of adult stem cell research and embryonic stem cell research. Throughout my findings, I have discovered that I feel as if adult stem cell research is more beneficial for many people because adult stem cells offer a possibility of a renewable source of replacement tissues and cells, adult stem cells have the ability to differentiate in to other types of cells, and also adult stem cell research can further advance the possible cures and benefits that adult stem cells provide, that can further provide treatment for diseases, disabilit...
