A discussion on the embryonic stem cell research

Similar embryonic-type stem cells can also be obtained from aborted fetuses. These cells, called induced pluripotent cells or iPSCs, have many of the same properties as embryonic stem cells. BiologyWise Staff The controversy that surrounds embryonic stem cell research has varied angles to it, chief among them being the ethical and moral values attached to it.

A portion of stem cell researchers use embryos that were created but not used in in vitro fertility treatments to derive new stem cell lines.

The moral status of the embryo is a controversial and complex issue. It therefore does not have any interests to be protected and we can use it for the benefit of patients who ARE persons.

InPresident Barack Obama lifted the federal funding ban on embryonic stem cell research, making it a historic moment in the American medical research fraternity.

The efficiency of establishing embryonic stem cell lines from nuclear transfer embryos is currently unknown, but expected to be lower than from IVF embryos. Experiments carried out within the last two years have demonstrated, for example, that bone marrow cells can give rise to nerve cells in mouse brain Mezey et al.

Like ESCs, they are pluripotent. Chapter 1 of this film introduces some of the key ethical arguments. But there is a difference between losing some nerve cells and losing the complete nervous system - or never having had a nervous system.

An early embryo that has not yet been implanted into the uterus does not have the psychological, emotional or physical properties that we associate with being a person. Neural stem cells are committed to the neuronal lineages neuronsastrocytesand oligodendrocytesand thus their potency is restricted.

Nevertheless, the prospect of autologous transplantation of haematopoietic stem cells of bone marrow in the long term makes this an important research area in terms of alternatives to therapeutic cloning see below. Salhan, Sudha August But when scientists learned how to remove stem cells from human embryos inboth excitement and controversy ensued.

There is also risk in some of the procedures used to get stem cells out of the body such as from liposuction or spinal tap or to deliver stem cells to the body such as implanting them in the heartbrainspinal cord, or other organs.

What are embryonic stem cells.

Frequently Asked Questions (FAQs)

Even though the human embryo is tiny at this point, as human beings and in solidarity with that life, we are not free to allow its use simply as a commodity for our convenience or benefit.

But there are several main disadvantages to using adult stem cells: T his BioEthics Education Project video is an introduction to the ethical issues in stem cell research. Given their unique regenerative abilities, stem cells offer new potentials for treating diseases such as diabetes, and heart disease.

Research teams in the United States and Japan have developed a simple and cost-effective method of reprogramming human skin cells to function much like embryonic stem cells by introducing artificial viruses.

A final variant on adult stem cell sources concerns the use of embryonal carcinoma EC cells, a stem cell population found in tumours teratocarcinomas of young adult patients.

Ethical Issues in Stem Cell Research

While research is going on in this field, extracting stem cells from skin or bone marrow, is quite a difficult procedure as compared to the ease of obtaining stem cells from embryos.

The debate on embryonic cell research has been one of the hottest topics in the international media in the recent few years. Watch video · Embryonic stem cells offer hope for new therapies, but their use in research has been hotly debated.

Different countries have chosen to regulate embryonic stem cell research in very different ways. Mention embryonic stem cells in the pub and the topic still divides opinion. The use of human embryos for research on embryonic stem (ES) cells is currently high on the ethical and political agenda in many countries.

Despite the potential benefit of using human ES cells in the treatment of disease, their use remains controversial because of their derivation from early embryos.

Although the discussion here concerns.
