Stem cells get their name from the fact that they are basic cells that other cells develop from. They are capable of developing into a wide range of cells. Stem cells could potentially be used to grow new cells to replace the cells that were destroyed or damaged by age or disease, or the side effects of treating diseases. Once they change, they cannot be changed back. Stem cells can divide to create more cells before they start to change (Freedman 6).
There are two types of stem cells: adult and embryonic. Adult stem cells are produced in bone marrow in the arm and leg bones. They are more mature than embryonic stem cells, so they can’t change into as many types of cells (Freedman 8). Embryonic stem cells can be taken from leftover embryos at fertility clinics or from embryos from terminated pregnancies (Freedman 10). Scientists take the stem cells from early embryos and use them to create cells found in 200 different types of tissues (Freedman 8). There are also umbilical cord stem cells that can be obtained from the blood that comes out of umbilical cords (Freedman 9). They are less mature than adult stem cells but more mature than embryonic stem cells (Freedman 10).

...acilities but do not agree with making embryos in vitro. Southern Baptists strongly oppose the use of embryonic tissue from aborted embryos (StemCells Inc.)
All types of stem cell research should be supported and funded. There are so many ways we can potentially use them. In the last 20 years, more than 20,000 patients have received umbilical cord blood transplants, treating mostly leukemia and blood disorders in children (NIH Stem Cells). Although, there is a lot of research left to do to use stem cells to their full extent, the amount our scientists can do with them is amazing.

- Stem cell research has been grabbing attention and debate from the scientific community as well as in the media. Although the application of stem cells is not limited to regenerative medicine, a great majority of scientists believe that stem cell research could be a promising source to replacing damaged neurons causing movement disorders which often occur post-stroke (1). Stem cells are not a new discovery; In fact, scientists have known of the existence of these self-renewing, unspecialized cells for over a century (1)....

- Stem Cell Research Stem cell research can be a beneficial aspect to the healthcare system worldwide because of its significance in curing several types of disease. In many cases, research scientists have demonstrated that stem cells research can play a dynamic role by treating patients with different types of illness. In addition, it has been view as the new upcoming treatment in the health care system that is capable of easing many type of uncommon diseases such as Alzheimer’s disease, spinal cord disease, Parkinson disorder, Lou Gehrig disease, and others....

- A mother cannot remember her children’s names anymore because of Alzheimer’s diseases. A daughter will never be able to walk again because of a car accident that has made her paralyzed from the waist down. A husband will never be able to see his wife again because he has become blind. But maybe these people will be able to remember, walk or see again. Someday all of the diseases in the world may be curable through stem cell research. Stem cells are very unique because they have the ability to morph into any of the over 200 cells that make up the human body.... [tags: Stem Cell Research ]

- Potential benefits of using embryonic stem cells There are many applications of embryonic stem cells in both research and for development of treatments and therapies. Research on embryonic stem cell is used for thorough investigation to find and achieve a more complete understanding of complex processes regarding human development, cell division and cell differentiation. [Women’s Health] [NIH 2015]. The information from these research may yield information about the origins of diseases and disorders such as Parkinson’s, Alzheimer’s, multiple sclerosis, cancers, many of which are due to abnormal cell division and differentiation [Stem Cell & Regenerative Medicine Center] [NIH 2015]....

- The article “Stem Cell Research,” elaborates on the medical benefits that come from stem cell research. It defines exactly what stem cells are and how their abilities can be harnessed and applied to treat chronic human ailments and degenerative diseases. It goes on to present supporting and opposing views that challenge its progress and reviews the role the government is taking in the issue (Stem Cell Research). There is significant scientific information that supports the potential for stem cells to treat or possibly cure various diseases that afflict humanity.... [tags: Pro Stem Cell Research]

- Sam is a fifteen year old girl who has been fighting cystic fibrosis her whole life, and at this age she knows her life is cut short and will barley make it past the age of thirty. Kids who are born with this have an abnormal gene, and something as simple as that can cut someone’s life short. Modern technology and science has changed the world we live in today, from creating things as simple as a play station four’s or a smart phone to creating the power to genetically clone human race. Scientist could genetically modify genes to be cured from diseases like cystic fibrosis, Huntington disease, and even breast cancer but many argue that this wouldn’t be an ethical thing to do....

The research on the development of stem cells and cloning has benefits scientifically, ethnically, and medically that are outgrowing today’s surrounding controversy. Adult and/or Embryonic stem cells are conjoined with animal cells to clone. In the process of cloning, genetic material is transferred between the human and the animal cell. To begin with, stem cells can establish several different cell types in the human body during the times of early life and growth.... [tags: Stem cell, Cellular differentiation]
