Stem cell research has attracted much attention from all over the world for its immense potential in improving and regulating a variety of body functions. Stem cells are those groups of cells which can generate specialized cells and organs that have specific functions to perform. Two main sources of stem cells include embryos during the early phase of embryonic development and adult stem cells. Stem cells from both these sources have the potential to grow into or create specific cell types. History of stem cell research can be traced the back the to late 1800s at which time scientists were experimenting with mammalian egg fertilization processes, but achieved success only in 1959 with the successful production of rabbits through in-vitro fertilization. This paved way for fertilization of human eggs. The first in-vitro fertilization of human eggs was successfully achieved in 1981 in the United States (Viegas, 2003). Numerous groundbreaking discoveries have been made through research conducted all over the world. These researches have uncovered the immense potential these stem cells have on human life. However, the research field also faces many economic, religious, ethical and moral dilemmas and limitations from federal policies in the West and also East. Stem cell research is impacted at an international level because most of the researches are funded from Western Nations.
The source for embryonic stem cells is the human embryo which is not more than 5 days old; this stage is commonly referred to as the blastocyst phase. This embryo is derived from in-vitro fertilization (IVF) at clinics where the fertilization process is carried out in a test tube and then implanted into the womb of a woman. In the normal pregnancy, blastocyst stage continues till the 10th week of gestation after all major organs are created. The blastocyst consists of the inner cell mass or embryoblast and outer cell mass or trophoblast.   ...Download file to see next pagesRead More

...the theoretical side of the question, and 3) transplant center in order to compare the shared ideas of other study participants with the thoughts provided by medical personnel who had a chance to use embryonic stem cell research in practice. As Yin (2011) emphasized, site selection should be purposeful. The proposed method will suit this requirement. The sampling technique will be purposeful and strictly aimed at recruiting health professionals working in stem cell research field. Age, gender, and other demographic characteristics will be included in the selection criteria since they are very important...

Human and Embryonic Stem cell research

...of research. This is becoming harder and harder to keep politically, due to the fact that the rise of people in favor of embryonic stem cell research is increasing. Many private companies are starting to take advantage of this situation by providing funding and many scientists are eager to take advantage due to the fact that it does not use federal funding. These scientists are hoping to show the power of stem cells, as a medical technique in that they can be programmed into whatever is required for a patient. The debate of the destruction of embryos is not an issue due to the fact that they are used at in vitro clinics...

Concern Related to Embryonic Stem Cell Technology

...whereas adult stem cells form during adulthood. It is evident that embryos which undergo stem cell collection may not survive. The logic of saving the life of a person by destroying the life of an embryo is often questioned by religious leaders and sociologists. In their opinion, there is no point in saving a life at the expense of another life. On the other hand supporters of embryonic stem cell technology are of the view that human life is more important than an embryo’s life. In their opinion, embryos cannot be labeled as human and therefore the human right issues are not applicable...

Embryonic Stem Cells Research

...stem cell research utilizes embryonic stem cells but, the religious leaders are of the opinion that adult stem cells are an alternative that is viable for use (The Pew Forum on Religion & Public Life, 2008, Para. 3). The Catholic Church and most Christian groups view the research as murder as it results in the destruction of human embryos. To them these embryos have rights by virtue of being human; thus, their dignity and the right to life must be respected from the moment they are created. However, some Christian groups, the Episcopal church, are in support of the...

Adult Stem Cells – a Better Alternative than Embryonic Stem cells Based on the above findings and according to Diane Irving, a professor at Georgetown University, adult stem cells are better than embryonic cells because they are closer to the cells that require replacement. The important thing needs to be noticed is that chances of genetic errors with adult stem...

...). Advantages of the Embryonic Stem Cell Research - a promise foretold Supporters of the embryonic stem cell study raise positive statements regarding the benefits that humans can reap if it will be allowed to continue. One potential importance of the human stem cell lines is its promise for cell-replacement therapies. This means the human embryonic stem cells can heal damage tissues in some major organs. Since it has pluripotency characteristics, these cells can replace worn-out tissues...

...researchers have established other potential sources of diverse adult tissues. These include; umbilical cords discarder after babies are born, human placenta, bone marrow, fat, nerves, amniotic fluid, pulp of baby teethe and muscles. All these have been found to be a source of versatile stem cells. Such serious disease like childhood leukemia, juvenile, diabetes, Alzheimer's Parkinson, spinal cord injuries, heart diseases, multiple sclerosis, cancer, burns have found their cure (Hams, 35). The achievement made so far regards these diseases and methods used have not violated the moral ethics respect and dignity of the human person. Effects of bio cloning to moral...

Human embryonic stem cell (heSC) research

...Embryonic stem cell research Embryonic stem cells are pluripotent, meaning that they have the ability to develop into any form of human tissue. They are extracted from the blastocyst of mammalian embryo. They are unique because they have the ability of unlimited undifferentiating proliferation in vitro in culture. They also differentiate into the three germ layers derivatives that are the endoderm, mesoderm and ectoderm. In addition, they are unspecialized, making them fit for use in any part of the body. Their capacity to develop into cardiomyocytes shortens several embryonic development processes....

Embryonic Stem Cell Research

...Embryonic Stem Cell Research Blastocyst encompasses hollow structures in progression of early embryos, which is an important source of embryonic cell lines in humans. These cell lines are not specific to one tissue or organ therefore they have the ability to produce cells of any type. Through studies and research on how these cells work in formation of the skin, blood or even bones it has become possible to also study their functioning as well as what happens when a particular disease attacks them. With these understandings, doctors and...
