Stem cells a technology assessment essay

Stem cells in drug development One way that stem cells are used at the moment is in developing and testing new drugs.

However, the creation and destruction of embryos is involved in this process. For this reason, not all are supportive of embryonic stem cell research and the controversy surrounding it is still so much in the picture. What Are Stem Cells?

These are unspecialized cells found in living things and are able to renew themselves and develop into other cells by means of growth and repair so long as the host is still alive.

They can also be manipulated to become tissue or organ specific cells. What are embryonic stem cells? Basically, these are cells derived from blastocysts which are day old embryos. Most of these sources come from unfertilized in vitro eggs and are used in research studies.

These eggs are taken with consent from donors and brought to laboratories for scientists to use. Embryonic stem cells are important because they have several potential uses, from getting information about cell development to creating new drugs for medical disorders such as diabetes and cardiovascular disease.

During this stage, the egg divides into smaller cells and become what is known as blastocyst. This is then harvested and grown on a petri dish and divide to become embryonic cells.

This process wherein cells are grown in an artificial environment is known as cell culture. This is used in cell engineering, molecular biology and stem cell.

Although both can become differentiated cell types, cells from embryos are pluripotent. Adult cells have limited capabilities to differentiate into other cell types. Moreover, adult stem cells are not as available as embryonic stem cells, making them hard to culture in laboratories.

When it comes to transplantation rejection however, embryonic stem cells are more likely to be rejected as opposed to adult stem cells, according to scientists especially that there have only been few clinical trials done to test the effect of human embryonic stem cells on transplantation.

Despite the potential benefits of embryonic cells, there are also possible setbacks surrounding its applications. Supporters and critics continue their debate on this controversial issue and express their views on different forums.

Scientists are also divided based on ethical and moral concerns. Here is a look at some of the pros and cons of embryonic stem cell research that are worth looking into. They are not to be considered to have life.

On the issue whether embryos have moral status, proponents claim that at this point, these embryos should not be considered as persons because they lack physical and psychological properties human beings have because they have not yet been implanted in the uterus.Catholic Support for Ethically Acceptable Stem Cell Research Sometimes it is wrongly said that the Catholic Church opposes stem cell research.

In fact, the Church supports ethically responsible stem cell research, while opposing any research that exploits or destroys human embryos.

Because students can typically answer a multiple choice item much more quickly than an essay question, tests based on multiple choice items can typically focus on a relatively broad representation of course material, thus increasing the validity of the assessment. Cultured meat, also called clean meat, synthetic meat or in vitro meat, is meat grown from in vitro animals cell culture instead of from slaughtered animals. It is a form of cellular agriculture.. Cultured meat is produced using many of the same tissue engineering techniques traditionally used in regenerative medicine. The concept of cultured meat . Related Journals of Stem Cell.

A vast spectrum of therapeutic interventions is based on stem cell technology, ranging from inert bio-materials to pluripotent, virally-modified cells.
