Rui Nuno McLellan 2/25/14 Biology 8:35 Tues-Thurs Stem cells Due March 4th All term papers will follow the combined theme of Biotechnology and "Stem Cell Research". Please select your topic relating to some aspect of stem cell research or biotechnology or both. There are many things that make stem cells so unique. These characteristics gives them the potential to cure human diseases, because they are not specialized into becoming a certain cells yet, which allows them to be reprogrammed into whatever cell is needed. Also, there ability to regenerate and the usability brings scientists and researchers an endless supply of living cells, which can then be modeled and transported, to a worthy participant. The body is made up of many types of cells including blood, skin and many others. What many people fail to understand is that all of those cells came from one single cell. The start of the human body came from one cell, a fertilized egg. After that process has taken place, the cell begins cell division and starts to become two cells, then four and so on. All of these cells are indifferent, not showing any physical or internal differences. These cells have not been assigned a job or to carry out any human functions yet besides multiplying. These embryonic stem cells have the ability to self-renew which would allow a continuous supply of stem cells. They also have the ability to become a specialized cell, which can then carry out functions of that specific cell. This is very important because once a stem cell has been arranged to become a specialized cell, it loses its ability to transform into a different specialized cell. Stem cells can be present in some adult bodies not just newly formed fertilized eggs. Some of these ste... ... middle of paper ... ... injury, and other neurological brain disease target neural stem cell transplants. There are many ways we can use stem cells and many more we will soon find out with more scientific advancements. If we can all embrace this idea who knows what kind of body repair stem cell research could bring. The futures direction for stem cells research is bright. New experiments shown in mice, that self-repairing cells found in the brain can be stimulated the same way as we stimulate our immune system with a vaccination. If this is possible in humans we can bypass the need for stem cell transplant. Scientists are still trying to discover a drug that can stimulate cell regeneration in the brain. Research is bringing us closer to having stem cells in every clinic, but until further research is done for safety and efficiency needs, stem cell research can only stay in a laboratory.
Stem cells are the building blocks of the human body. Embryos consist of unspecialized stem cells that transform into the various specialized cells in the body such as cardiac, muscle or bone cells. Fetuses also have stem cells. However, the stem cells are divided into types like muscle, bone or nerves and don't perform a specialized function. Surprisingly, adult bodies also contain stem cells. In adults, stem cells are undifferentiated but limited to specific tissue type. When needed, the stem cells transform into the cells needed for repair and maintenance. The most common source of adult stem cells is bone marrow. Researchers also acquire stem cells from umbilical cords. Without stem cells, embryos could not develop into fetuses and adult
The body is composed of cells, which form the basic unit of life. Unique cells found in the body are the stem cells. These cells are biological cells that are not specialized for particular functioning in organisms. They can be distinguished since they have the ability to differentiate or divide into multiple body cells, and their ability to replicate self. They are unique in the way they can renew themselves by undergoing cell division when inactive for a long period. It is also possible to induce stem cells to organs or tissue cells under some conditions. When the cells divide, they replenish the cells in a living organism. They serve as an internal system that repairs and replaces the tissues that are worn out.1 Dividing cells may remain as stem cells or become specialized in their functions, for instance red blood cells, brain or muscle cells.
Stem cells can be thought of as blank slates or cells that have yet to become specialized. They can be transformed to become cells with special functions.
Stem cells are pluripotent cells of the body which are “undifferentiated.” This means that stem cells can ultimately give rise to any type of body tissue. Thus stem cells have the potential to cure a vast number of diseases and physical ailments including Parkinson’s, diabetes, spinal cord injury, and heart disease. Consequently, stem cell research and the development of associated medical applications are of great interest to the scientific and medical community. The area of stem cell research involving human embryonic stem cells is of particular interest in that embryonic stem cells are derived from week-old blastocysts developed from in vitro fertilized eggs. As opposed to adult stem cells, which must undergo a complicated process of de-differen...
Because stem cells are essentially a blank slate, scientists are theoretically capable of growing any human tissue cell. There is enormous medical potential in this. Stem cell research is the next step in advancing the medical field. It is comparable to the discovery of penicillin or the inoculation for smallpox.
Stem cell research began in 1956 when Dr. E Donnall Thomas performed the first bone marrow transplant (“Adult stem cells are not more promising,” 2007). Since that time, research has evolved into obtaining cells from a variety of tissues. According to stem cell research professors, Ariff Bongso and Eng Hin Lee (2005), “Stem cells are unspecialized cells in the human body that are capable of becoming cells, each with new specialized functions” (p. 2). Stem cells are in various adult tissues, such as bone marrow, the liver, the epidermis layer of skin, the central nervous system, and eyes. They are also in other sources, such as fetuses, umbilical cords, placentas, embryos, and induced pluripotent stem cells (iPSCs), which are cells from adult tissues that have been reprogrammed to pluripotency. Most stem cells offer multipotent cells, which are sparse...
Stem Cells are cells that scientist have began to try and use to help people. “In the mid 1800s it was discovered that cells were basically the building blocks of life and that some cells had the ability to produce other cells.” With the discovery of stem cells came the opening to a new area of development in what could be done with health and medicine of the world. Of course throughout history, stem cells have been a very heated subject between different groups of people who believe it is right or wrong. Some people believe that this form of research is against ethical or moral values. They too see this as being wrong because they view human embryos as a form of life. These cells are neutral cells that can be turned into any other one that is needed at the time. Stem cells can make more of themselves when they aren’t being used allowing them to be ready when something happens. In the human body, stem cells help repair the tissue that has been broken, torn, or lost. They help fix bones, heal abrasions, and even repair internal organs if needed. Scientist have the ability now to mani...
The importance of embryonic stem cells rests in their lack of specialization. These basic cells are present in the earliest stages of developing embryos and are able to develop into virtually any type of cell and tissue in the body. Being self-renewing, they offer a potentially limitless source of cells and tissue. (Tucker)

This report aims to investigate the different views held on the pros and cons of development in stem cell research. This report will provide background to the debate, its social significance, parties that are involved and analysis of the arguments related to the topic researched.
Drugs can be tested on stem cells that develop into the target tissue before using it on human test subjects, which improves safety. Finally, transplantation of organs created from stem cells could eliminate the need for human organ donors.... ... middle of paper ... ... The 'Standard' of the 'Standard'.
Could you imagine being able to create new organs, tissues, muscles, and even food? With embryonic stem cell technology, believe it or not, these things are possible. Stem cells are the body's raw materials. Specifically, they are cells from which all other cells with specialized functions are generated. Under the right conditions in the body or in a laboratory, stem cells can divide to form more cells called daughter cells. These daughter cells either become new stem cells or turn into specialized cells with a more specific function, such as blood cells, brain cells, muscle cells or bone cells. The possibilities are almost endless. The debate and main issue with this technology is that the actual stem cells come from embryos. Embryos are an unborn or unhatched offspring in the process of development. Although there is controversy surrounding these cells, embryonic stem cells should continue to be researched and used, because they have so much potential.
For decades, biologists have been using stem cells to figure out possible cures for different diseases and even prevent them. Stem cells are cells that can become useable in certain tissues in the body (according to an infant), or tissue cells that are already found in blood, bones, the brain, and skin (in adults or children). Stem cells are being used for patients with lymphoma (begins in the immune system), leukemia (cancer of white blood cells), and other types of blood disorders.
