Should stem cell research be legal
What is stem cell research
However, because they cannot yet create cells that mimic cancer cells in a controlled way, it is not always possible to replicate the results precisely. The legislation should provide broad, principled ethical standards so that the science itself can evolve in the direction that experimentation and serendipity takes it—alongside easily adapted regulations governing the research, based on the broad ethical standards approved by Congress. Obtaining adult stem cells, such as from bone marrow, can be painful. It is not a fetus. Where do stem cells come from? SCL: By this line of reasoning, human embryos are inviolable and should not be used for research, even if that research might save many lives. Federal funding of stem cell research will generate many of these patents. For some people, life starts when a baby is born, or when an embryo develops into a fetus. The blastocyst represents such an early stage of embryonic development that the cells it contains have not yet differentiated, or taken on the properties of particular organs or tissues—kidneys, muscles, spinal cord, and so on. Those who fail to take seriously the belief that embryos are persons miss this point. The laws surrounding the two differ because while both have similar capacities in differentiation, their modes of derivation are not. Scientists will be able to learn more about genetics and unique human traits. However, by , scientists had already started using pluripotent stem cells. MS: In the course of treating infertility, American fertility clinics routinely discard thousands of human embryos.
This paved the way for Mario CapecchiMartin Evansand Oliver Smithies to create the first knockout mouseushering in a whole new era of research on human disease. Embryonic stem cells were isolated in mice inand in humans in As a result, this technique does not have the same ethical concerns.
The researchers believe that this material will replace fillings, as the stem cells would prompt the damaged teeth to heal themselves. Foremost among these was the discovery in August that adult cells can be reprogrammed into a pluripotent state by the introduction of four specific transcription factors, resulting in induced pluripotent stem cells.
Such blastocysts are either cloned in the lab or created in fertility clinics. Bharadwaj, Aditya; Glasner, Peter E. MS: Consider an analogy: although every oak tree was once an acorn, it does not follow that acorns are oak trees, or that I should treat the loss of an acorn eaten by a squirrel in my front yard as the same kind of loss as the death of an oak tree felled by a storm.
The legislation should provide broad, principled ethical standards so that the science itself can evolve in the direction that experimentation and serendipity takes it—alongside easily adapted regulations governing the research, based on the broad ethical standards approved by Congress.
SCL: What is the basis for the belief that personhood begins at conception? Just as acorns are potential oaks, human embryos are potential human beings.
