What is stem cell technology?
stem cell technology is a medical research of a study of stem cells of human and animals. Stem cells are naturally occurring cells necessary for the growth and regeneration of organisms. Stem cells are already used for therapeutic purposes and research suggests that the future future benefits of stem cells in many areas of medicine. However, this research is controversial because some stem cell technologies include the use of human embryos. They are able to transform themselves into any of the specialized cells necessary for the growth and maintenance of organs. In the development of embryos, they become cells necessary for the formation of different organs. In later life, they complement these organs by replacing dead or sick cells. One of the functions of stem cell technology is to achieve a better understanding of this complex process. Bone marrow transplantation, Communications The treatment of leukemia patients is one form of stem cell technology. Some scientists believe that a similar use of stem cells wouldIn the end, it could have treated diseases as diverse as diabetes, nervous disease, Alzheimer's loss and auditory loss. If genetic research can explain the functioning of stem cells, they could theoretically be used to replace these diseases or destroyed cells of damaged or destroyed.
It is not clear whether stem cell technology will be able to overcome potential disadvantages to such treatment. For example, stem cells can actually create cancer if they are allowed to grow in the body without regulation. Tissue rejection is also a problem, as with any organ transplantation, if the source of stem cells is someone other than the patient. The use of adult stem cells from anywhere in the patient's body could overcome these problems, but these options need to be examined.
Many research technology of stem cells is carried out by means of stem cells from animals such as mice.Human stem cells are sometimes removed from frozen embryos saved in front of practices such as in vitro fertilization. This embryos are no longer needed and are used with the permission of the donor. However, the practice remains controversial because many people believe that these embryos form a living human being.
Scientists discovered in 2007 to synthesize stem cells called induced pluripotent stem cells, from other cells to manipulation with the gene. This has the potential to enable therapeutic use of stem cells without embryo involvement. This is not a perfect solution because cancer remains a risk, but such cells harvested from the patient may not be susceptible to the rejection of the tissue. Stem cell technology is still in its infancy, but potential benefits for humanity could be huge.
