Research paper on stem cells
This dilemma is called embryonic stem cell research, and it has caused conflicts with peoples’ opinions, morals, and religion for years.... All cell culture procedures were performed under sterile conditions in laminar class ii biohazard safety cabinet (esco).

One thing that seems to be reliable to treat all diseases and disorders is stem cell research.

Instrumental use of ch into the development of cell‐replacement therapy requires the instrumental use of pre‐implantation embryos from which hes cells are derived since current technology requires lysis of the trophectoderm and culture of the icm; the embryo disintegrates and is thus destroyed. These cells, known as stem cells, produce nearly all the other cells and tissues found in the human body (sobel sep 4, 22).
Though this field is rapidly progressing, several limiting factors have reduced the efficacy and survival of many transplanted cells. Due to self-renewal property and differentiation capability of stem cell, it becomes a new hope in modern treatment.

It has been suggested that stem cell therapy is the answer to treating many patients greatly improving their quality of life.... Broadly speaking, two types of stem cell can be distinguished: embryonic stem (es) cells which can only be derived from pre‐implantation embryos and have a proven ability to form cells of all tissues of the adult organism (termed ‘pluripotent’), and ‘adult’ stem cells, which are found in a variety of tissues in the fetus and after birth and are, under normal conditions, more specialized (‘multipotent’) with an important function in tissue replacement and cells are derived from the so‐called ‘inner cell mass’ of blastocyst stage embryos that develop in culture within 5 days of fertilization of the oocyte (thomson et al.
The adult individual, a variety of tissues have also been found to harbour stem cell populations. The most revolutionary option would be the creation of embryos specifically for the purpose of isolating stem cells via ‘nuclear transfer’ (‘therapeutic cloning’).
In the final analysis, the debate about embryonic stem cell research is not primarily about medical benefits. The ethical issue surrounding embryonic stem cells research arises because human embryos are destroyed in the process.

The argument on whether human cloning/ stem cell research should be deemed acceptable still exists. The isolation of hes cells for research into cell‐replacement therapies operates as a catalyst for this discussion.

All of those things and more could be a thing of the past with the incredible potential of stem cell research.
It has even been suggested that the results from adult stem cell research are being misinterpreted for political motives and ‘hints of the versatility of the adult cells have been over interpreted, overplayed and over hyped’ (vastag, 2001). Embryonic stem cell is one of the most controversial, widely discussed medical issues in the united states today.
The precise implications of this difference in moral status for the regulation of the instrumental use of embryos need further ethical the principle of proportionality and a permissive interpretation of the principle of subsidiarity, make a moratorium on the isolation of hes cells el research on alternatives is important and requires major support. Stem cell research gives a great opportunity to patients with incurable and/or deadly diseases that have been around for many centuries....
Two types of stem cells are key to unlocking the complex coding of cellular make-up and those are embryonic and adult stem cells. Cells that have the ability to become, basically, any other cell in the body are called stem cells.
Critics of the use of hes cells claim that at least three such alternatives exist, which have in common that they do not require the instrumental use of embryos: (i) xenotransplantation; (ii) human embryonic germ cells (heg cells), and (iii) adult stem question is not whether these possible alternatives require further research (this is, at least for the latter two, largely undisputed), but whether only these alternatives should be the subject of research. The acid-bath method creates viable induced pluripotent stem (ips) cells recent breakthroughs in stem cell research are helping to narrow the ethical divide surrounding the use of embryonic stem cells.
An example of the logical version is that acceptance of hes cells for the development of stem cell therapy for the treatment of serious disease automatically means there is no argument against acceptance of use, for example, for cosmetic rejuvenation (nuffield council on bioethics, 2000). 2001) has also been reported, but the controlled expansion and differentiation to specific cell types is an area where considerable research will be required before cell transplantation becomes clinical practice (for review, see passier and mummery, 2003).
