Throughout diseases, such as Parkinson’s, diabetes and strokes.

Throughout history there have been a variety of medical discoveries that have saved people’s lives, methods including pills and surgery treatments are the most generally known, accessible and recognized.

There have been other not as recognizable methods that have come to the medical world earlier, such as cell treatment, although it is yet to be accepted and recognized by society, there is a promising future forthis method to cure the diseases that other treatments are unable or uncertain. In this new field, there are controversial and challenging factors specifically about the experimentation of “Stem cells”. This essay will be focused on what are stem cells, their functionalities, thebenefits and limitations and main problems in society that are generated by stem cells.

A stem cell is an immature cell of the body; stem cellsfunction to generate all the other specialized cells or to form new stem cells. They can divide to evolve more cells called daughter cells inside the body or in a laboratory. Daughter cells then develop into a specialized cells or in a new stem cell.

Only stem cells have the capacity offorming other type of cells. Stem cells can also provide restoration for affected organs and tissues. They receive a signal about the injured zone and rush through the blood system to repair the problem. It is believed that in the future, stem cells have a reassuring chance of been used as an official treatment to cure diseases, such as Parkinson’s, diabetes  and strokes. Adult stem cells. This cells are found in small quantities in adult tissues, such in fat or in the bone marrow. These cells have a more limited capacity to transform into diverse cells of the body compared to embryonic stem cells.

Not long ago, scientists thought that adult stem cells could form different type of alike cells. For example, stem cells situated in the bone marrow could only create blood cells. Although, there has been evidence that adult stem cellshave the capability to form different type of unrelated cells. For example, the bone marrow’s stem cells  are able to form cardiomyocytes or osteocytes. This investigation has led early stage clinical trials to examine the efficacy and safety in people.

For example, currently adult  stem cells are examined in people with cardiac and neurological disease.Although there have been positive discoveries about adult stem cells, it is still a fact that adult stem cells are less enduring and versatile than embryonic stem cells. Adult stem cells can’t be controlled toreproduce all type of cells, which limits the way it can be applicated to treat diseases.

Adult stem cells are also more exposed to theanomalies due to environmental risk, such as toxins, or errors produced in stem cells during multiplication.Embryonic stem cells. These type of stem cells come from embryos that have a life span of 3 to 5 days. In this phase, an embryo is defined as a blastula and contains around 150 cells.These are pluripotent  stem cells, cells which can divide in a larger quantity of stem cells or form into any other type of cell.

Because of its adaptability in it’s functions, embryonic stem cells could be used to repair or recreate malfunction organs or tissues.Embryonic stem cells are taken from embryos in early stages, a group of cells that are formed when the women’s ovum is fertilized with the sperm of a man in a in vitro fertilization clinic. Many concerned questions about the ethics of this investigation are caused because embryonic stem cells areobtained from human embryos. Although embryonic stem cells is the best option for future studies and application in diseases, it is a complicated subject and term to define whether or not it is right to carry on experimenting with embryonic stem cells because there is a collision of diverse opposing, but equally valid views that are affected by moral, ethical and political values.There is a noticeable line between both opposing groups.

On one of the group’s perspective, it is considered that children are alive the minute they are conceived. Others believe that the child does not have the awareness yet, it would have to take months until the child has a brain and it is considered to be alive. An embryo is sacrificed in every procedure of the embryonic stem cell research.

Even though the embryo has not yet developed, and is purposely made for the research in the in vitro fertilization, there is still a debate on whether scientists are killing innocent lives or not. If  the problem of this group of people is the fact of killing a life, then it is needed to be taken as consideration that 73% of in vitro fertilization embryos don’t survive. It would mean that 1 out of 4 embryos will survive and the others would be wasted.  Even though there is a large group against the abstraction of embryonic stem cells, many medical researchers think it is necessary to keep investigating these stem cellsbecause the the result could change and potentiate medicine without harming any lives. The excess of embryos  or the failed ones from the in vitro fertilization could be donated to research clinics. Although there are many positive factors about embryonic stem cells, there are also serious limitations to consider.

One of the main problems is donor rejection. For example, there are some cases where the body might reject a transplant as it may detect an unknown organism and would simultaneously attack the organ. This reaction from the body would cause serious infection and illness to the patient. Depending the situation, not just those symptoms would appear, but also the cell could mutate and could cause tumors. Another serious disadvantage is, the procedure of obtaining eggs. Women who donate eggs would go through a painful and long process, with the limitations of only donating a certain number of eggs at one go.

After the surgery there is a risk of infertility. That adds up to the possibility of bleeding and infection that could also affect the ability for a women to conceive children. ConclusionI believe stem cell research is right for society. If medical researches are able to perfect the treatment, a lot of diseases andinjuries will be cured. There would be a world with less sick, there won’t be anyone that couldn’t walk, no one dying of a terminal illness.

If the donors are volunteering to give away their eggs there is no problem, it’s their bodies. There is no reason why researchers wouldn’t take advantage of dead embryos for a good cause. Anyways the egg was made for that purpose and has no consciousness or organs. It is not a human.

Stem cell research is a tremendous discovery and possible new field in medicine, it could benefit people in so many ways, it is our era’s cure. This research has saved many lives and will continue to with the research still developing. Stem cell research is not taking lives, it is saving thousands upon thousands who have the chance of losing it.
