The Ethics of Stem Cell Research.

Extracts from this document...

Introduction

The Ethics of Stem Cell Research Biology Amy Ng The Ethics of Stem Cell Research Since there is really no right or wrong in this world, it is not quite possible to tell if it is right or wrong for a patient to choose his principles and not take the stem cell operation. The patient can say, "Yes" or "No" according to their own thoughts and how successful will the operation will be. Stem Cells are blank cells that have not been differentiated yet and they are able to develop into cells of any kind in the human body. Researchers hope to use stem cells to repair tissues or renew and organ. There are three types of stem cells. ...read more.

When the human embryos are 3-5 days old from the day that they were fertilized, the stem cells are extracted. They are then are placed in a dish, so they could be harvested to become any type of cells or tissues, in the laboratory. Other than being a large medical potential, they are also thought as being killing human lives because when the stem cells are extracted, it ends the life of the embryo. Some people think that killing the embryo is also a kind of murder. But, some say that is not morally wrong because they can save other people's lives and decrease human suffering. Later, researchers found out another way to obtain stem cells. Stem cells can be also found in adults, not only the embryo, stem cells found in the bone marrow can also develop into other types of cells in the human body. ...read more.

Conclusion

There are two types of stem cells in the bone marrow. There is the Hematopoietic stem cell and the Bone Marrow Stromal cells. The Hematopoietic stem cell forms all types of blood cells in the body and the Bone Marrow Stromal cell generates cartilage, fat, bone, and fibrous connective tissue. Parkinson's disease causes the death of brain cells to produce dopamine, it produces effects such as increased blood pressure and heart rate. Researchers discovered that the umbilical cord blood stem cells might help speed up the recovery of the Parkinson's disease. It might also be able to cure the Alzheimer's disease and avoid using embryonic stem cells. In conclusion, stem cell research helps decrease human suffering and finds ways to cure serious diseases. Researchers are finding other ways and uses of stem cells, so they do not involve in using embryonic stem cells, which is said to be killing a human's life. ...read more.
