BIO.152 Buse Gizem Danış 2011207120 Embryonic Stem Cells vs Induced Pluripotent Stem Cells: Why do they Generate so Much Excitement Stem cells have an ability to change into other types of cells in body or in laboratory during early life and growth. Since stem cells can generate into a range of cell types such as bone, muscle, skin, cartilage and other specialized types of cells, they have the potential to treat many diseases like Parkinson's, Alzheimer's, diabetes and cancer. It is expected that they may also be used to create organs, which means that patients no longer need organ transplants and related surgeries in the long term . Therefore, thanks to the stem cells, the problems of finding a suitable donor and transplant rejection can be solved . "Stem cells are like little kids who, when they grow up, can enter a variety of professions," Dr. Marc Hedrick of the UCLA School of Medicine says. "A child might become a fireman, a doctor or a plumber, depending on the influences in their life -- or environment. In the same way, these stem cells can become many tissues by making certain changes in their environment." There are three types of stem cells, namely unlimited stem cells ( also known as embriyonic stem cells ) , limited stem cells ( also known as adult stem cells ) and induced pluripotent stem cells (iPSCs) which are produced in the lab by reprogramming adult cells to express ES characteristics. Initially, ebriyonic stem cells are isolated from a four- or five-day-old human embryo that is in the blastocyst phase of development. They are currently obtained with patients’ permission from donors. The embryos are usually extras that have been created in IVF (in vitro fertilization) c... ... middle of paper ... ...derlying pluripotency and differentiation.As it is said above, there are three types of stem cells, including ebriyonic stem cells, adult cells and induced pluripotent stem cells. While there are still many ethical, political and technological barriers to the clinical use of stem cells, they may help to eradicate many disease (therapeutic cloning), and possibly create even for the generation of organs for transplantation (also known as regenerative medicine).

  • Should Stem Cells Be Used In Medical Research Essay

    604 Words  | 2 Pages

    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 cells unique nature has scientists intrigued to do research with the focus of finding a way that these cells can be used to replace patients’ injured or diseased tissues. Advancement is made to all the three types of stem cells namely embryonic stem cells, adult stem cells in addition to induced pluripotent cells. Embryonic cells are the building blocks of an embryo that is developing, and can develop into almost all body cell types. Somatic cells are found in the body tissues. They renew and regenerate in healthy bodies. The third type which is induced pluripotent is genetically modified embryo cells from skin cells.2 Research on these cells are geared towards saving humanity; a noble course.

    “Through the isolation and manipulation of cells, scientists are finding ways to identify young, regenerating ones that can be used to replace damaged of dead cells in diseased organs. This therapy is similar to the process of organ transplant, only the treatment consists of the transplantation of cells rather than organs. The cells that have shown by far the most promise of supplying diseased organs with healthy cells are called stem cells.” (Chapter Preface)

    Late one night a woman is driving home on the freeway, she’s hit head on by a drunk driver and killed. The man is charged with two accounts of murder; the woman, and her four-week-old embryo inside her. By law, everyone human being is guaranteed rights of life; born or unborn they are equal. The same law should be enforced concerning human embryonic stem cell research. Dr. James A. Thomson discovered stem cells in 1998 and they’ve intrigued scientist ever since. The stem cells themselves are derived from a three to four day old cluster of cells called a blastocyst and they are so coveted because they are pluripotent, meaning they can differentiate into any type of cell in the human body. Although embryonic stem cells show amazing potential to cure various disease such as cancer, congestive heart failure, Alzheimer’s and Parkinson’s disease, muscular dystrophies, and more. The methods by which they are obtained is controversial. Research on embryonic stem cells is unethical, unnecessary, and purely homicide.

  • The Debate Concerning Embryonic Stem Cell Research

    1400 Words  | 3 Pages

    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...

  • Stem Cell Research Debate

    1200 Words  | 3 Pages

    Stem cell research is a heavily debated topic that can stir trouble in even the tightest of Thanksgiving tables. The use cells found in the cells of embryos to replicate dead or dying cells is a truly baffling thought. To many, stem cell research has the potential to be Holy Grail of modern medicine. To many others, it is ultimately an unethical concept regardless of its capabilities. Due to how divided people are on the topic of stem cell research, its legality and acceptance are different everywhere. According to Utilitarianism, stem cell research should be permitted due to the amount of people it can save, however according to the Divine Command of Christianity, the means of collecting said stem cells are immoral and forbidden.

    Stem cells have the ability to transform into any kind of cell. These cells can divide and also replenish other cells in the body, such as muscle cells, brain cells, red blood cells, or they may just simply remain as stem cells. Stem cells are able to replicate even after long periods of dormancy. They naturally repair damaged tissues and can be experimentally induced to work with particular tissues and organs (NIH, 2013).

    Those who favour stem cell research are optimistic about the continued developments in stem cell research will open doors to many breakthrough discoveries in biomedical science. The scientific and ethical questions arise as rapidly as the reaching of milestones in stem cell research. There are two main types of stem cells, namely embryonic stem cells and adult stem cells. Adult stem cells are undifferentiated cells in our body. But they have restricted-range of cells that they can further differentiate. On the contrary, embryonic stem cells have the ability to differentiate into nearly two hundred cell types in the human body, called pluripotency. The process of harvesting embryonic stem cells involves destruction of embryos (Mooney, 2009).

  • Embryonic Stem Cell Research Persuasive Essay

    2065 Words  | 5 Pages

    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.
