Harbour 1 Jarrod Harbour November 27, 2006 English 101 Stem Cell Research Scientists and medical researchers have come a long way in people’s healthcare. People are living longer and healthier lives than ever before. There are new ways to prevent cancer and researchers are developing more surgical procedures than ever in medical history. One of the most controversial medical issues is embryonic stem cell research. Embryonic stem cells haven’t helped one patient yet, but it just might be the future of the healthcare field. Embryonic stem cell research should be accepted and pursued in modern society because it promises the cure of diseases, can repair tissues and cells, and make people live longer. The embryonic stem cell originates in the embryo, where the egg and sperm fuse together to result in fertilization. After four or five days, the embryo is created in a blastocyst, a small group of cells usually containing about 64 cells (Malcolm and Wobus 18). Inside the blastocyst, there are stem cells that are pluripotent, which means that stem cells can be made into over 200 cell types in the human body (Malcolm and Wobus). These stem cells are just generalized and not made to be specified in the beginning. With 200 cell types able to be made, it would become an enormous asset in creating new cells (Malcolm and Wobus). Just like regular cells, stem cells divide through a process called mitosis. When stems cells divide, more cells are newly made. In result, stem cells create new tissue that cannot be replaced naturally.

Harbour 2 At the most basic level, pluripotent stem cells could help us to understand what happens in human growth and development (Clemitt). The primary goal for microbiologists would be the identification of the factors involved in the cellular decision-making process, which results in cell specialization. For cell specialization, turning genes on and off is central to this process, but it’s not known why genes do this process (Clemitt). Some of the most serious medical conditions, such as cancer and birth defects, are due to abnormal cell specialization and division (Clemitt). In biology, scientists consistently learn about cell division and mitosis to understand more about cancer and the mutation of cells. With stem cells, biologists can observe newly-made cells and find out why mutations are created to make the several types of cancers (Feldman). For patients with cancer and other cell mutating diseases, treating them may become much easier for both doctors and patients. Stem cell research is also known as cell therapy. Cell therapy can be defined as a
