Embryonic stem cells research
Stem cell research could be one of the biggest breakthroughs in medical history. Stem cell research has shown a great promise and advance in its technique since 1998 when human stem cells were isolated for the first time. Since then research on stem cells has received much public attention both because of their extraordinary potential in curing devastating diseases and because of relevant legal and ethical issues. Research in human developmental biology has led to the discovery of human stem cells. Two major stem cells research are embryonic stem cells and adult stem cells. Recently, techniques have been developed for the in vitro culture of stem cells, providing unprecedented opportunities for studying and understanding human embryology. The understanding of the science is particularly important for discussing ethical and policy issues. I’m going to discuss technical details about embryonic stem cells. Then, I’ll discuss their advantages and disadvantages of embryonic stem cells. Finally, I’ll discuss the debate concerning with the stem cells research.
Stem cells come from human embryos created in the laboratory- usually through in-vitro fertilization. Scientists inject the sperm into the egg. A day after the egg is fertilized, it splits into a two-celled embryo. The next day, it splits into four cells, then into eight cells. By the fourth or fifth day after fertilization, the embryo is a multi-celled ball called a blastocyst. At this point, the embryo is very tiny about the size of the dot on an “i”. It can either be implanted into a woman’s womb to start a pregnancy, or it can be frozen to start a pregnancy at a later time. It can also be used for research. (CNN, David Muhlhausen)
If the embryo is used for research, scientists remove stem cells from inside the blastocyst, which destroys the embryo. The stem cells are cultivated in the lab and can multiply indefinitely. Scientists treat the cells to coax them...
