Since these cells are capable of differentiating into nearly all cell types, they serve as imperative research tools for the improved development of treatments and therapies for a vast number of diseases and conditions. Adult stem cells are undifferentiated cells, which are found throughout the human body after development. These cells multiply and divide in an effort to replenish any dying cells or damaged tissues in the body. These cells are multipotent, meaning they can differentiate into multiple, but limited cell types (Fritsch et al., 2008). Another type of stem cell that is of particular interest is induced pluripotent stem cells (iPS cells).
The liver, bone marrow, heart, brain, and muscle all have cells that are capable of differentiating into cells of that same type. These are called stem cells, and are a new medical tool that is helping regrow vital organs in our body to help us survive. Stem cells can come from adult cells, or the blastocyst of the embryo. The cells that come from these are undifferentiated, and can be specialized into certain cell types, making them available for many damaged tissues in the body. While using stem cells in the body is a main use, they are also being used to help doctors understand how disease processes start.
There are primarily two different types of stem cells that scientist work with, embryonic stem cells and adult stem cells. Embryonic and adult stem cells each have many advantages and disadvantages regarding their potential use. Adult and embryonic stem cells differ in the number and type of cells that they can become. (Antkowiak, 2001). ?Embryonic stem cells are cells from the embryo that have the potential to become a wide variety of specialized cell types,?
The possibilities for stem cell use are endless and cloning is a new way to achieve them. Potential problems may include further ethics debates and a possible shortage of donor eggs, but I believe scientists will overcome these obstacles.
It is significant to know possible risks of using stem cells, as well as their benefits. Basically, stem cells are unspecialized cells in the human organism, which have a significant ability to renew themselves and become specialized with new functions. They have distinguishing properties to develop into different types of cells, such as brain cells, nerve or liver cells etc. The stem cells repair dead cells; moreover they can divide without any limitations. Generally, there are four sources of stem cells: stem cells from embryo; stem cells from fetus; stem cells from adult human; stem cells from umbilical cord.
Knowing the basics of stem cells is important to understanding how they might positively influence those with different types of medical conditions. Stem cells are defined as unspecialized cells capable of renewing themselves through cell division. (stemcells.nih.gov) Stem Cells develop in many different cell types during the early stages of life and development. As long as a human or animal is alive the many tissues in the body assist on any internal repairs in the tissue. Stem cells can either stay stem cells or become more in detail and become a muscle cell, a red blood cell, or a brain cell.
There are still many technological advances to be made in the area of stem cells before they can be used. In order for all these advances to take place, we need government funding, not personal differences and gains. Despite the argument of the ethical issue, political and religious, along with scientific, stem cell research is opening a new door in medical science that will change the world and the lives of everyone forever.
One of the most controversial topics in the field of biomedicine has been the research of embryonic stem cells. Stem cells are extremely fascinating to what they can do they have the potential to develop into many different cell types in the body during early life and growth. In many tissues they serve as a sort of internal repair system, dividing without limit to replace other cells as along as the person is still alive. When stem cells divide they could become specialized cells such as muscle cells, red blood cells, brain cells, and etc. their unique generative abilities, stem cells offer a new potential for treating diseases such as diabetes, and heart disease.
There are various types of stem cells that can be used for therapy including embryonic, adult, and umbilical cells. Embryonic stem cells are gathered from the cell mass of an unfertilized egg from a variety of sources including animals and humans. Adult stem cells can be found in various places of the body where they are used to replace old cells or tis... ... middle of paper ... ...ved, they should be compensated for their donation. The taking of cells from an oocyte can be dangerous to the donor, so taking such a risk for the purpose of helping others and furthering research should be rewarded and detailed informed consent should be of utmost importance to the doctors or scientist. Stem cell therapy for genetic disease is providing great opportunities for the discovery of a cure for thousands.
One of the new techniques being practiced today is stem cell therapy. Stem cell therapy can be defined as a group of new techniques, or technologies, that rely on replacing diseased or dysfunctional cells with healthy, functioning ones. ( Langwith 23) These new techniques are being used to treat a wide variety of disorders such as Parkinson’s Disease and Lou Gehrig’s Disease. To be able to comprehend the importance of the discovery of stem cells, it is crucial to understand the terms and definitions that go along with the topic of stem cells. A stem cell is derived from a human embryo, scientists are able to keep these stem cells alive and have them replicate after extraction.
