Stem cell research may be promising and has potential to the cure of many diseases. However, it can also be expensive and there are risks as well as ethical issues involved.
What are the pros and cons of stem cells?
One major pro of stem cells is that it can be contrasted with differentiated cells whereby there is much hope offered for the advancement of various medical fields. They have high ability to differentiate and grow into any kind of cell in human body. For instance, when neural cells which are mainly found in spinal cord and in the brains, they can be replaced by cells generated from stem cells. More also, diseases such as cancer when they are treated by chemotherapy or radiation it leads to huge damage of those cells and they are destroyed and eliminated from the body. Through stem cell research new cells can be generated which are used to replace the destroyed ones and they can easily adapt to the affected area which brings back the normal functioning of the body. Dead cells which occur as a result of injury or disease, they can be replaced into new healthy cells in any part of the body which is taken to the normal functioning of the body. Therefore stem cells are found to be quite flexible.
How do stem cells help with diseases?
With research, most scientist have believed that therapy of the stem cells can result to revolutionary way of treating there deadly diseases by repairing those body tissues that are diseased and damaged and generating healthy ones for replacing them. A lot of research is needed to evaluate how various stem cells work so that a way can be invented on how to treat their conditions.
What is the difference between mature and young stem cells?
The young stem cells are pluri-pontent which gives it ability to differentiate and making any cell in the body whereas those of mature stem cells they are multi potent and they have limited flexibility and this hinders it ability to become any body cell type. The mature stem cells are quite uncommon and as one ages, their cells become scarcer in the body. For the young stem cells, they are readily available since many blastocysts for research are readily available today which have been acquired through IVF while other new methods such as somatic cell nuclear transfer (SCNT) are coming up to help with the research. With the invention of this technology there is no high risk of immune rejection because this will enable patients to use their own cells (Cowan, 2004, 1354).
How can stem cells be used in research?
Stem cells research can enable one to come up with an ideal way of identifying various factors that results to differentiation of stem cells to become more specialized cell type. The factors which are identified can be used to drive tissue regeneration and repair of various damaged tissue if they are given therapeutically. More also, valuable biological information can be acquired which relates to development of human being, genomic imprinting and also somatic cell aging are valuable information that can be acquired when research is carried on the study of the human pluripotent stem cell.
Why do people oppose embryonic stem cell research?
Therefore, on ethical grounds it is believed that human life begin from the time an egg became fertilized and so those who value human life have greatly opposed the idea of embryonic stem cell research. Since when stem cells are extracted from the embryo, it means that the embryo needs to be destroyed in order to facilitate research and obtain the cells. This has been valued as taking away of human life which has been seen as murder (Popular Issues, 2002). Embryonic research has revealed that the tiny blastocyst have no elements of human features and further studies shows that there are new stem cell lines, which have existed as a result of in vitro fertilization (IVF). According to research, it has been noted that there are many fertilized human cells that are already banked today but they are not being used for research and for ethical purpose. Many have advocated that new human life should not be claimed at the expense of experimentation.
Why is stem cell research important?
Stem cell research is quite important in many issues which regards to human body. The research which has involved mainly the scientists want to make use of stem cell’s ability to differentiate into many cells in treating various diseases such as Parkinson disease, diabetes, Alzheimer or head condition. They also believe that the research can enable them test drugs sensitivity and they can also develop other types of drugs. Productive and cell biology knowledge can also be gained by vast research made on stem cells. Basically, stem cell research has great potential of improving human health by use of stem cell therapy.
Why do mice die from embryonic stem cells?
Some research have revealed that when mice were used for experimenting embryonic stem cells in treatment of Parkinson diseases, it revealed that some mice which were treated with the embryonic stem cells eventually died as a result of tumor which developed on the brain (David P. 2005). It has also been noted that when embryonic stem cells are stored for a long time, they develop chromosomal abnormalities which eventually result to cancer cells. Therefore, for quite good reasons, funds that are used for research in embryonic stem cells can otherwise be used in better ways by funding the adult and the umbilical cord research which have been proved to be very useful in the lives of many.

How long after conception do embryonic stem cells grow?
1. The embryonic stem cells are harvested 5-7 days after conception.#N#Adult stem cells do not provide the same benefits as embryonic ones from a therapeutic standpoint. They fall short in their viability to treat genetic diseases. That’s because the same disease found in the adult body can be present in their stem cells. When the harvesting takes place, it occurs during the first week after conception. At this stage, the embryo has not yet developed to a stage where a personal identity can be assigned to it, nor can it live outside of a specialized environment. It is essentially a mass of cells.
How do embryonic stem cells form?
Human embryonic stem cells come from a transference of cells from a preimplantation-stage embryo in a laboratory culture dish. It is mixed with culture medium, allowing the cells to divide, and then spread over the surface of this dish. These cells can then develop into all three derivatives of the primary germ layers, making it possible for them to eventually turn into one of the over 200 different cell types that are found in the human body.

Embryonic stem cell research received $347 million, while umbilical cord blood or placenta-based stem cells received $34 million. 7. Many of the stem cell lines under research are two decades’ old. Most of the approved embryonic stem cell research lines that are worked on in the United States were created on or before August 2001.
