Background Info? Bone marrow transplantation restores stem cells that were destroyed by high doses of chemotherapy and/or radiation therapy. After being treated with high-dose anticancer drugs and/or radiation, the patient receives the harvested stem cells, which travel to the bone marrow and begin to produce new blood cells. Bone marrow is the soft, sponge-like material found inside bones. It contains immature cells known as hematopoietic or blood-forming stem cells. Bone marrow is the spongy tissue inside some of your bones, such as your hip and thigh bones. It contains immature cells, called stem cells. The stem cells can develop into red blood cells, which carry oxygen throughout the body, white blood cells, which fight infections, and platelets, which help the to blood clot.It is used to treat diseases such as leukemia, anemia, and multiple myeloma.Before you have a transplant, you need to get high doses of chemotherapy and possibly radiation. This destroys the faulty stem cells in your bone marrow. It also suppresses your body's immune system so that it won't attack the new stem cells after the transplant. How is it used/benefits? Bone marrow transplantation (BMT) restores stem cells that have been destroyed by high doses of chemotherapy and/or radiation therapy. One reason BMT is used in cancer treatment is to make it possible for patients to receive very high doses of chemotherapy and/or radiation therapy. Chemotherapy and radiation therapy generally affect cells that divide rapidly. They are used to treat cancer because cancer cells divide more often than most healthy cells. However, because bone marrow cells also divide frequently, high-dose treatments can severely damage or destroy the patient’s bone marrow.

Potential long-term risks include complications of the pretransplant chemotherapy and radiation therapy, such as infertility (the inability to produce children); cataracts (clouding of the lens of the eye, which causes loss of vision); secondary (new) cancers; and damage to the liver, kidneys,lungs, and/or heart. You can easily get infections after the transplant because your immune system is weak. The risk of infections decreases as your immune system recovers. Transplant recipients sometimes are given vaccines to prevent viruses and infections, such as the flu and pneumonia. If you develop an infection, your doctor will prescribe medicine to treat it. GVHD is a common complication for people who get stem cells from a donor. In GVHD, the new stem cells attack your body.
... it, which destroys all healthy bone marrow in the body. As a result of this, the patient will have to undergo a process to replace all deteriorated or damaged bone marrow. This process involves taking the stem cells from a donor and transplanting them into the patient’s body, so that the patient will transform these stem cells into bone marrow. Bone marrow can also be a complication for the body if it escapes into the blood stream. If the bone marrow enters the blood stream, it can travel throughout the body, and cause serious complications. This is a condition referred to as fat embolism, and mainly occurs after serious trauma or surgery to lower limbs. There is not a specific diagnosis or treatment for this; it is mostly based on the patient’s condition or symptoms. Bone marrow can be a very dangerous thing if it has any type of complications within the body.
Stem cells are the building blocks of the human body. Embryos consist of unspecialized stem cells that transform into the various specialized cells in the body such as cardiac, muscle or bone cells. Fetuses also have stem cells. However, the stem cells are divided into types like muscle, bone or nerves and don't perform a specialized function. Surprisingly, adult bodies also contain stem cells. In adults, stem cells are undifferentiated but limited to specific tissue type. When needed, the stem cells transform into the cells needed for repair and maintenance. The most common source of adult stem cells is bone marrow. Researchers also acquire stem cells from umbilical cords. Without stem cells, embryos could not develop into fetuses and adult
Specific Purpose: After listening to my speech, my audience will know the history of organ transplants/transplantation and its medical advances over the years.
As the healthcare field continues to grow and evolve at an accelerated rate, new and advanced technologies are sprouting up everyday and becoming increasingly commonplace. A technology that has garnered both positive and negative attention is transplanting stem cells. Hematopoietic stem cells refer to the body's blood forming blood cells (American Cancer Society, 2013). Here is some background information on these types of stem cells. These cells are young and immature.
“Through the isolation and manipulation of cells, scientists are finding ways to identify young, regenerating ones that can be used to replace damaged of dead cells in diseased organs. This therapy is similar to the process of organ transplant, only the treatment consists of the transplantation of cells rather than organs. The cells that have shown by far the most promise of supplying diseased organs with healthy cells are called stem cells.” (Chapter Preface)
When asked how he feels about the advancement of science to places that were once notions to be the job of the creator, Dr. Martin Luther King replies by saying, “Cowardice asks is it safe? Expedience asks is it political? Vanity asks is it popular? But the conscience asks is it right?”
Current cancer therapies are very painful, and involve the destruction of good tissue as well. Stem cells that destroy cancerous tissue can be engineered, and used to kill all cancer cells in a body. By injecting stem cells that destroy only cancer cells, no harm is done to good tissue.
Many parts and systems of the human body can be impacted by cancer. The system of blood that supplies oxygen and nutrients is one such area. Leukemia is cancer that starts in the tissue that forms blood. Most blood cells are formed in bone marrow called stem cells. Bone marrow is the soft jelly-like substance in the center of bones. Once the cell is mature, it develops into different types of blood cells, each type performs a specific task. These cells include erythrocytes also known as red blood cells and leukocytes also known as white blood cells. Leukocytes are potent infection fighters and they come in the form of B-cells, natural killer cells, helper T-cells, and cytotoxic-T cells. Adoptive cellular therapy is a treatment used to help
...with these side effects, researchers are worried that cancer cells are capable of genetic mutations that make them resistant to damage done by chemo and radiation (Radiation Therapy Side Effects). That is where stem cells come in handy. When embryonic stem cells are applied to the tumor they try to repair the damage done and can prevent the cancer from spreading or creating a secondary cancer. Also, using stem cells would be a more natural way to rid of the disease. Since a patient would be using human cells to attack the cancer there are no traumatic side effects that come with it. Some of the few side effects of stem cell transfusions include irritated skin where the transfusion was made and fatigue. Typically these symptoms fade away three months after the transfusion (Dr. Martin, Thomas, and Lisa Considine). Cancer affects many families around the globe.
There are a few problems with the process. The most common being is the same as any other transplant, the body doesn't accept the new cell stem cells if the cells aren't exactly the same as the patients; instead the body's immune system recognizes them as unwanted cells and rejects or destroys them often causing more damage to the body. The most common use of stem cells is bone marrow transplant. Some adult stem cells are usually found in bone marrow, when the marrow is transplanted the cells regenerate and help replace the failing surrounding marrow. However, this type of procedure doesn't involv...
To understand where and how leukemia occurs it helps to know a little about the blood and lymph systems. Bone marrow is soft inner part of the bone where blood cells are formed There are three different types of major blood cells; white blood cells, red blood cells, and platelets. In infants active blood cells are found in almost in all bones but by the teenage years they are found in mostly flat bones (skull, shoulder blades, ribs, and pelvis) and the vertebrate. Bone marrow consist of a small number of blood stem cells, more mature blood forming cells, fat cells, and supporting tissues to help the tissue grow. They go through a series of changes to make new blood cells. With this process 1 of 3 things is made- red blood cells, white blood cells, or platelets. Red blood cells carry oxygen from the lungs to all the other parts of the body and transport carbon dioxide back to the lungs. Platelets are cell fragments made by a type of bone...
Blood cancer is a life-threatening disease that includes: leukemia, lymphoma and myeloma (American Society of Hematology). Leukemia is classified into myeloid and lymphoid leukemia. Each type has acute and chronic phases. Leukemia reduces the ability of white blood cells (WBCs) to fight infection (American Society of Hematology). In addition, leukemia limits the bone marrow’s ability to produce red blood cells (RBCs) (American Society of Hematology). It is one of the most common cancers in the world and can be treated by chemotherapy and bone marrow transplant.
...t that could be because the patient doesn’t take the correct mandatory health percautions or the body rejects the transplant. Jonathoan Finger was a transplant patient, with his first transplanted kidney failing, “The fact he hadn’t taken care of the kidney he’d recieved less than two years earlier caused emotional pain,”(Storch 44). Jonathan learned the hard what you have to care for your body especially after organ donation. Because not everyone is given an second chance and it could mean your life.
You’re 50 years old now. You haven’t taken care of your body as well as you thought you did and now you must go through hundreds of tests to see if you can get that new organ that you need. Would your chances of survival be good if you needed a transplant back in the 1800’s? What about present time? Do you have a chance of living a long life? Does the future truly look brighter for transplants? You’ll learn about your chances of a successful transplant in both the past, present, and future.
...there are some risk factors in using stem cell for therapeutic approaches, hematopoietic stem cell therapy by bone marrow transplantation has already been proofed to be safe if donors’ background and screening, cell contamination, HLA matching and opportunistic or nosocomial infections during immunocompromised period were carefully monitored and controlled. Still, other types of stem cell therapies, despite of their good therapeutic efficacy, are remain in experimental stage and need more data to support and demonstrate the safety in clinical trials. More understanding of stem cell biology is also required in order to keep stem cell under controlled and avoid some complications that they might cause. So, to pave the way for successful stem cell therapy, research in this extent is needed to pursue to maximized therapeutic efficiency with highest safety in patients.
