Essay about Leukemia And Stem Cells

The unique properties of stem cells are that they are capable of dividing and renewing themselves for a long time. This means they can multiply as many times as they want and grow into lots of different types of cells. They are also under certain physiologic and experimental conditions. They can produce tissue or organ-pacific cells with special functions. There are three classifications of stem cells. There are Totipotent, Pluripotent and Multipotent. Each one of these classifies stem cells in a certain way. Totipotent cells can change into all cells types, Pluripotent cells can change into most cell types and Multipotent cells can change into certain cell types. There are two major types of stem cells, Embryonic and Adult. Although they are both major types of stem cells they are very different from each other. Embryonic stem cells can change into all types of cells and Adult stem cells can change only into certain types of cells. Embryonic stem cells are classified as Totipotent and Pluripotent. Adult stem cells are classified as Multipotent. Another reason why Embryonic and Adult stem cells are different is because they have

Leukemia Leukemia is a group of blood diseases characterized by cancer of the blood forming tissues. It was discovered in Europe during the XIX century when a group of doctors directed by John Hughes Bennett tested their patients and discovered their elevated number of white blood cells. It was then called “white blood” and later was named leukemia from the words greek words “leukos” (white) and “hemia” (blood). Leukemia is a disfunction of the bone marrow stem that over

Stem cells are cells with the potential to become any type of cell in the body. There are two different types of stem cells: adult stem cells and embryonic stem cells. Adult stem cells are very valuable and are used mainly to treat blood diseases, but sometimes adult stem cells from the brain are used to treat neurological diseases. Adult stem cells can also be difficult to recognize in the adult body. Embryonic stem cells are more flexible than adult stem cells and can be used for a bigger variety of diseases (California’s Stem Cell Agency,2011). Some people do not believe in the use of embryonic stem cells, because they believe they are killing future life. Despite the controversy over how stem cells are gathered, stem cells have undeniable

Stem Cells are the unspecialized cells from which differentiated cells develop. Scientists say that stem cells are totipotent. I will talk about that later. There are two different types of stem cells. One is an embryonic stem cell and the other is an adult stem cell. The two are very different. Let’s talk about the difference.

One type of Stem cells is embryonic stem cells. 5 or 7 days into a fertilization process, the egg divides rapidly and produces a ball of cells called a blastocyst in which all the cells are alike. Gradually, after this stage, the cells start differentiating. Differentiation involves the expression of some genes from the organism’s genuine in the cell, but not others. This process assigns each cell specific purposes and once differentiation takes place, it cannot be reversed in most cases. Cells in the blastocyst have the potential to turn into almost any cell types: they are said to be pluripotent and are known as embryonic stem cells. These cells are isolated from the inner cell mass of blastocysts of pre – implantation stage embryos. The properties of embryonic stem cells are still kept.

Leukemia is a cancer that affects the bone marrow. The bon marrow is the soft spongy center of the bone that produces blood cells. Leukemia is found in white blood cells or leukocytes. The white blood cells help to fight ff infections and other diseases. Normally, cells produce in an orderly way, but people that have leukemia the cell production gets out of control. The marrow produces too many immature white blood cells called blasts. They are differently shaped and can’t carry out their usual duties.

Stem cells (underlying biology): Have the ability to expand into multiple new cell types in the body throughout early life and growth. when a stem cell splits ,every current cell has the ability to carry on as a stem cell or develop into different cells with a greater specialized purpose, like a muscle cell, a red blood cell and a brain cell.

In very simple terms, stem cells are cells that have the strong ability to become any number of other cells. “Stem cells are distinguished from other cell types by two important characteristics. First, they are unspecialized cells capable of renewing themselves through cell division . . . Second, they can be induced to become tissue-or organ-specific cells with special functions” (NIH 2002, 1). There are two extensive groupings of stem cells in which scientists primarily work with. These include embryonic stem cells and adult stem cells. Embryonic stem cells are “derived from the developing

Over the decade, stem cell research has been ongoing around the world experimenting ways to control stem cells safely and effectively in the hope of curing as many diseases and help as many patients as possible. Stem cells are the foundation cell of our bodies. They are immature blood cells that have the remarkable potential and the ability to divide and form hundreds of copies and develop into various types of cell. Thus, it can be used to develop healthy tissues or organs to replace those that are damaged. In theory, there is no limit to the types of diseases that could be possibly treated with stem cell because it has the potential to develop into many different types of cell in the body. There are many people suffer in

Aplastic Anemia is a rare disease in which a person’s bone marrow fails to produce new blood cells. Bone marrow is the spongy tissue found in some of our bones and is responsible for blood cell formation, hematopoiesis. Our bone marrow is given the task to generate red blood cells, which carry oxygen, white blood cells, which fight foreign entities, and platelets, which are responsible for blood clotting. In children, bone marrow is found in the long bones such as the femur, and in adults it is mostly found in flat bones such as the sternum and pelvic girdle. Patients who are diagnosed with Aplastic Anemia are deficient in all three blood cells, due to damage to

Stem cells are unique cells because of their special features. First of all, they are able to regenerate themselves through the process of cell division. Each time this process happens, each new cell created can become another type of cell. Secondly, if they undertake some conditions, they can become tissue and organ cells. There are two main types of stem cells that are being looked today, embryonic stem cells and adult stem cells (Also known as somatic stem cells). However, all stem cells have three main functions.

According to the National Institutes of Health, stem cells are the amazing cells that are capable of forming the entire human body. At the very beginning of life, fertilized egg cell divides repeatedly to form a group of stem cells that go on to eventually make all the organ and tissue in the body. Stem cell have the capability and prospective to develop into many different cell types in the body during early life and growth. The stem cell have the potential to divide into new cell, stay as a stem cell or become another cell. These cells can later become a cell with a more specialized function, such muscle cell, red blood cell, white blood cell and epithelial cell.

Now as we all grow up we ponder the idea of what our profession will be and the same approach comes into play with stem cells. There are two main types of stem cells, which are embryonic stem cells and adult stem cells. An embryonic stem cell is a undifferentiated cell that can give rise to all of the bodies cells and your existence in whole by choosing its profession. While most cells can only recreate more of its own kind;

Stem cells have the potential to develop and multiply into many different cell types in the body. Stem cells are able to divide throughout life without limit. This causes the stem cells to be able to develop into another cell type, which means it is specialised cell; to do a more specific function or it may remain the same. [5] As stem cells divide they have the ability to help to be able to renew or repair damaged tissue.[3,5]There are two main stem cell, Embryonic Stem Cells and Adult Stem Cells. [1,2,3] As my research question is about embryonic stem cells, I will discuss embryonic stem cells specifically. Embryonic stems cells are pluripotent stem cells that are derived from a human embryo that is four to five days old. An embryo,

     Another option is Bone Marrow Transplantation. In many cases of acute leukemia and cml, doctors give high doses of chemotherapy and radiation, when indicated to destroy all of the patient’s bone marrow, since it is not functioning correctly. Then they give the patient healthy bone marrow from the donor, whose tissue it the same or almost the same as theirs; ideally an identical twin or a sibling. They also might give bone marrow that was removed from the patient earlier and especially treated to remove any leukemia cells. Patients who have a bone marrow transplant bone marrow begins to produce enough
