stem cells

?Stem cells have the remarkable potential to develop into many different cells types in the body. Serving as a sort of repair system for the body, they can theoretically divide without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential to either remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell or a brain cell,? (National Institute of Health, 2004). In the face of prevention and treatment of human diseases, devastating illnesses such as heart disease, diabetes, cancer, Parkinson?s and Alzheimer?s continue to deprive people of health.

They distinguish themselves from other types of cells by ensuring two main characteristics: they are unspecialized cells adept at renewing themselves through cell division, and they can be prompted to become tissue for specific organs or cells with specialized functions. Research on stem cells can provide scientists with a better understanding of normal cell development. Although extensive research on stem cells can provide answers to many medical questions and cures to various medical conditions, embryonic stem cell research is a matter of great controversy due to the fact that embryonic stem cells are acquired from human embryos. Science and medical experts principally work with two types of stem cells which come from either animals or humans, these include embryonic stem cells and adult stem cells which are also called Somatic stem cells. There is a rich supply of adult stem cells found throughout the body in bone marrow, fat tissue, and even the amniotic fluid that surrounds and protects unborn babies.

Generally, stem cells are unique cells in the human’s body, which have an ability to renew themselves and become specialized into liver cells, kidney cells or spinal cord cells from unspecialized type of cells. There are several advantages and disadvantages of using stem cells in treatment the most common diseases of the world. The subject of this research project is to evaluate the benefits and risks of using stem cells in curing global diseases. It merits study, because stem cells are the constituent part of human organism and their abilities must be explored, in order to use them in therapies for diseases such as Alzheimer’s, Parkinson’s, diabetes mellitus, spinal cord injuries and cardiac disorders. It is significant to know possible risks of using stem cells, as well as their benefits.

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.

Thus, the requisition of stem cell research is imperative to elongating the existence of human life. Stem cells are a class of undifferentiated cells that are able to differentiate into specialized cell types. In addition, in many tissues, they serve as an internal repair system. When a stem cell divides, each new cell has the capability of either remaining a stem cell, or becoming another type of cell with a more specialized function, such as muscle cells, blood cells, or brain cells (Stem Cell Basics). "Stem cells have an interesting history that has been somewhat tainted with debate and controversy" (Murnaghan).

Recently, a renewed interest has been taken into a specific type of cell called the stem cell. According to Wikipedia, stem cells are undifferentiated biological cells that can differentiate into specialized cells and through mitosis (division of a cell in the nucleus), and can divide to produce more stem cells. These cells can be divided into two groups; adult stem cells and embryonic stem cells. Although stem cell research may bring about a positive change to our daily lives, the topic remains very debatable since many argue that stem cells may not live up to all of their expectations. Adult stem cells are relatively noncontroversial due to the fact t... ... middle of paper ... ...quivocal experiment.

Stem cells definitely have the ability to have a large impact in the science and medical fields. Science has grown so fast into finding new ways to treat a large number of different medical conditions and it is only a matter of time till these new findings are put into effect. The stem cells among us already have the ability to restore tissue and to also transform into different types of cells to fix diseases. The adult and embryonic cells are cells that scientists will continue to use to treat the many different diseases. Therefore, it is very important to know the basics of stem cells, the difference between the types of stem cells, and the possible uses of stem cells because science is moving quickly to have a promising future for those in need of medical help.

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.

Introduction As the human race progresses into more advance healthcare and discovered new strategies to cure diseases, stem cells become a debatable topic of interest for both the cell biologist and the common society. Stem cells have the ability to become any cell in the human body. A stem cell can be obtained from any adult tissues like organ, amniotic fluid. Stem cell for research purposes are obtained from a vitro fertilization clinic. As promising as it looks, it comes with an underlying risk that is associated with the use of stem cell.

These cells have the unique ability to differentiate into any type of cell. These cells are able to divide quickly, like they would during the process of fetal development. These qualities have made it possible for researchers to understand when and how certain cells differentiate, or change, to develop into different types of cells. Because of this, the researchers have been able to pinpoint the locations of certain genes and their gene switches, and are able to replicate this process in order to develop new tissue. These human embryonic stem cells are generated by a process of transferring cells from an embryo into a nutrient filled culture disc.
