The “Magical” Stem Cell

What if we can regrow our amputated hand back? Or recreate our broken kidney? Or save someone’s life through medical process. Most of you would say yes wouldn’t you? Thanks to science, particularly biology, allows us to do such thing. This “magical” cell is called stem cell. Stem cell is an undifferentiated cell of a multicellular organism that is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation. Instead of cloning the whole individual, its organs are the one that is cloned.
Stem cell can be obtained from two sources, human’s bone marrow and embryo. So far, embryotic stem cell is proven to be more versatile than adult stem-cell. It is due to the undifferentiated beginning of embyotic stem cell, embryotic stem cell has far greater potential to develop into any human organs.
I’m personally in favour of this stem cells idea. Embyonic stem cells can be use to renew our organ an it might as well increase human’s life expectancy. Not only “normal” organs that can be obtained from donors, but less common organ such as brain or spinal cord, or even the heart. Althoug this has brought up a lot of ethical discussion, such as the process of acquiring the stem cell. It is taken from an embryo, an unborn fertilized cells that is soon to be developed as a baby. If stem cell cloning goes public, there might be a possibility that illegal market on human embryo increase to fullfill the demand of patient that needs stem cell. Acquiring stem cell from embryo can be considered as murdering, although I these embryos have not been through any experience form life or experience what so called “life”.
It is also a possibility that peole in authority will have greater possibility to receive stem cell treatment, there will always be these conspiracy that puts the less privileged people in a harmful position. Issues such as stem cell cloning rose plenty of social issues.
