Preparation of Embryonic Stem Cells


Embryonic stem cells exist only in the early stages of embryonic development and are able to produce any type of cell in the body. The use of embryonic and fetal tissues revived the debate over the position of kernel and the beginning of human life. Now there was a substantial change in the parties concerned. So far, the debate was limited to groups "pro choice" who advocated the decriminalization of abortion and groups "for life" that assign the value of human person from conception to embryo (Takahashi, 2007).

The study of stem cells will allow us to understand the mechanisms of cell specialization. What mechanisms cause a gene to be active and do their job and what mechanisms inhibit the expression of that gene. Cancer, for example, is a case of abnormal cell specialization (Andrews , 2005).

Most cells of an adult (we are referring to man and higher mammals) are often multiplied, except for keeping some tissues such as blood and skin. Muscle cells and fat not normally divide. If you get fat, no more cells is that we actually have the same amount of cells, but these have increased in size.

Stem cells can be used to test new drugs in all types of tissue prior to actual testing in animals or humans. Stem cells have applications in cell therapy, regenerative medicine and tissue engineering. Many diseases are caused by malfunctions cellular or tissue destruction. One of the remedies, in severe cases, it is the transplant. Pluripotent stem cells may be used in cases of Parkinson and Alzheimer's, spinal cord injuries, burns, heart or brain injuries, diabetes, osteoporosis and rheumatoid arthritis (
