Bone Marrow Transplant | CureSearch

By Dr. Matthew Watson

Before the transplant admission:

When the healthcare team decides that BMT is the best treatment option for your child, they will schedule a lengthy conversation with you to explain the procedure. They will explain the many risks associated with BMT, as well as what you can expect before, during, and after the transplant.

Your child will undergo testing to make sure he/she is healthy enough to withstand the rigors of transplant. Testing will include evaluation of the heart function with electrocardiogram (ECG) and kidney and liver function, and infection status. Depending upon the disease, a bone marrow aspirate and spinal tap may be performed.

When your child is deemed healthy enough for BMT, physicians will usually insert a central line catheter that allows easy access to a large vein in the chest. The catheter will be used to deliver the new stem cells, as well as blood, antibiotics, and other medications during treatment.

Preparation Before Transplant:

Your child will be given preparative treatment, called conditioning before the transplant. Conditioning includes high doses of chemotherapy and sometimes, radiation of the whole body. The type and purpose of conditioning depends upon your childs underlying diagnosis but may include:

Commonly used drugs include:

The Transplant

Once conditioning is complete, stem cells are given through a catheter. This is very similar to a blood transfusion. After traveling through the bloodstream to the bone marrow, the transplanted stem cells will begin to make red and white blood cells, and platelets.

It can take between 14 and 30 days for enough blood cells, particularly white blood cells, to be created so the body can fight infection. The identification of new blood cells and an increase in white blood cells following BMT is called engraftment. Until then, your child will be at a high risk for infection, anemia, and bleeding. Your child will remain in the hospital until he or she is well enough for discharge.

Bone marrow transplant | UF Health, University of Florida …

By Dr. Matthew Watson

Definition

A bone marrow transplant is a procedure to replace damaged or destroyed bone marrow with healthy bone marrow stem cells.

Bone marrow is the soft, fatty tissue inside your bones. The bone marrow produces blood cells. Stem cells are immature cells in the bone marrow that give rise to all of your different blood cells.

Transplant - bone marrow; Stem cell transplant; Hematopoietic stem cell transplant; Reduced intensity nonmyeloablative transplant; Mini transplant; Allogenic bone marrow transplant; Autologous bone marrow transplant; Umbilical cord blood transplant; Aplastic anemia - bone marrow transplant; Leukemia - bone marrow transplant; Lymphoma - bone marrow transplant; Multiple myeloma - bone marrow transplant

Before the transplant, chemotherapy, radiation, or both may be given. This may be done in 2 ways:

There are three kinds of bone marrow transplants:

A stem cell transplant is usually done after chemotherapy and radiation is complete. The stem cells are delivered into your bloodstream usually through a tube called a central venous catheter. The process is similar to getting a blood transfusion. The stem cells travel through the blood into the bone marrow. Most times, no surgery is needed.

Donor stem cells can be collected in two ways:

A bone marrow transplant replaces bone marrow that is either not working properly or has been destroyed (ablated) by chemotherapy or radiation. Doctors believe that for many cancers, the donor's white blood cells may attack any remaining cancer cells, similar to when white cells attack bacteria or viruses when fighting an infection.

Your health care provider may recommend a bone marrow transplant if you have:

A bone marrow transplant may cause the following symptoms:

Possible complications of a bone marrow transplant depend on many things, including:

Complications may include:

Your provider will ask about your medical history and do a physical exam. You will have many tests before treatment begins.

Before transplant, you will have 1 or 2 tubes, called catheters, inserted into a blood vessel in your neck or arms. This tube allows you to receive treatments, fluids, and sometimes nutrition. It is also used to draw blood.

Your provider will likely discuss the emotional stress of having a bone marrow transplant. You may want to meet with a counselor. It is important to talk to your family and children to help them understand what to expect.

You will need to make plans to help you prepare for the procedure and handle tasks after your transplant:

A bone marrow transplant is usually done in a hospital or medical center that specializes in such treatment. Most of the time, you stay in a special bone marrow transplant unit in the center. This is to limit your chance of getting an infection.

Depending on the treatment and where it is done, all or part of an autologous or allogeneic transplant may be done as an outpatient. This means you do not have to stay in the hospital overnight.

How long you stay in the hospital depends on:

While you are in the hospital:

After you leave the hospital, be sure to follow instructions on how to care for yourself at home.

How well you do after the transplant depends on:

A bone marrow transplant may completely or partially cure your illness. If the transplant is a success, you can go back to most of your normal activities as soon as you feel well enough. Usually it takes up to 1 year to recover fully, depending on what complications occur.

Complications or failure of the bone marrow transplant can lead to death.

Is donating bone marrow painful? | Anthony Nolan

By Dr. Matthew Watson

The myth that stem cell or bone marrow donation is painful is extremely common and worryingly, it often stops people from registering to donate.

In 2016, a YouGov survey found that a shocking 34% of young men who wouldnt sign up as a stem cell donor were just tooscared that the experience would be painful.

We urgently need that to change because it couldnt be further from the truth.

I would 100% recommend it to other people. Its comfortable, painless and so worthwhile.Zachary, stem cell donor

It was painless and thats coming from someone with a fear of needles! I remember being amazed at how simple it was.Sean, stem cell donor

90% of people now donate directly from their bloodstream, in a procedure known as peripheral blood stem cell donation (PBSC).

Youll receive a series of four hormone injections to make your stem cells multiply into the bloodstream. Then youll head to a clinic, where the stem cells will be extracted from one arm, and your blood returned to the other.

And thats it. Some people report flu-like symptoms from the hormone injections, but these are usually mild and vanish within a few days.

Ive felt worse after a few bruising encounters on the football pitch. Within a week of the donation, I was back on my feet and feeling much better; all in all, its a very small price to pay for what could be achieved.Liam, bone marrow donor

Some people have asked me if it was painful or difficult. It was actually quite simple and nothing compared to what the recipient is going through at the same time.Andrew, stem cell and bone marrow donor

Just 10% of people are asked to donate from the bone marrow itself.

This is the procedure that lies at the root of the bone marrow donation is painful myth but in reality, it takes place under general anaesthetic, so you wont feel any pain while its happening.

Afterwards, youll probably feel a bit tired and bruised, and we recommend that you take a short break from work to recover. But thats all and it makes a lifesaving difference.

Tackling the myth that stem cell or bone marrow donation is painful is one of our biggest priorities.

Thats why we often ask our donors to share their stories, to bust the myths and show the world what donation is really like.

For a wide variety of donation experiences, just check out the Anthony Nolan Facebook page we usually add one or two new stories every week!

If you're aged 16-30, sign up to our lifesaving register by clicking on the link below:

Stem Cells Used in Cord Blood Treatments

By Dr. Matthew Watson

Stem cells are powerful, adaptable cells that can be used to promote healing and reverse damage. Stem cells are found in various places within the human body, but the purest stem cells are found in the umbilical cord.

Stem cells can be used in treatments for many different types of diseases. One of the main places young stem cells are found is in cord blood, which can be stored at birth and saved for future use if needed. Stem cells are also found in other places in the human body, including blood and bone marrow.

Regenerative transplants use stem cells from three main sources:

Bone marrow is tissue located in the center of your bones, making healthy blood cells that strengthen your immune system and fight off outside infections. A large amount of cells are located in bone marrow, and doctors frequently use hip bone marrow for most transplants, since the stem cells in this area are the most plentiful.

When doctors remove bone marrow, the patient receives anesthesia. This puts them to sleep and numbs any pain from the surgery. Doctors then insert a large needle, and pull the liquid marrow out. Once enough bone marrow is harvested, the solution is filtered and cryogenically frozen.

When a patient needs bone marrow for a transplant, stem cells are thawed and injected into the bloodstream. The cells then make their way to the bone marrow, and start producing new blood cells this process usually takes a few weeks.

While most people have a small amount of stem cells in their bloodstream, donors produce more stem cells after taking growth factor hormones. Doctors give these medications a few days before stem cell harvesting, which makes the bone marrow push more cells into the bloodstream.

During the harvesting procedure, doctors use a catheter to draw out blood. The blood moves through a machine, which separates stem cells and allows these cells to be put into storage. This process takes a few hours, and may be repeated over several days in order for doctors to get enough stem cells.

Stem cells are injected into the veins during a peripheral blood transplant, and naturally work their way to the bone marrow. Once there, the new cells start increasing healthy blood count. Compared to bone marrow transplants, cells from peripheral blood are usually faster, creating new blood cells within two weeks.

Umbilical cord blood contains a large amount of stem cells. If parents sign up for personalized storage or donation, medical staff will remove stem cells from the umbilical cord and placenta. The blood is then cryogenically frozen, and put into long-term storage.

While the stem cell count is smaller during a cord blood transplant, these cells multiply quickly, and researchers are studying new methods to increase cells naturally. Compared to bone marrow, cord blood cells multiply faster and dont require an exact match type to complete a successful transplant. Some techniques medical experts are testing to increase the amount of stem cells include:

While all three stem cell sources are used in similar procedures, they each have advantages and drawbacks. Bone marrow transplants are the traditional form of therapy, but peripheral blood cells are becoming more popular, since doctors often get more stem cells from the bloodstream.

The procedure for peripheral blood harvesting is easier on the patient than a bone marrow transplant, and stem cell transplants are faster. However, the chances for graft-versus-host disease, where donated cells attack the patients body, are much higher after a peripheral blood transplant.

Cord blood transplants are the least invasive, since they come from an external source the umbilical cord.

The biggest advantage for cord blood is the immaturity of the cells, which means transplants do not require an exact match. For bone marrow and peripheral blood transplants, donors need to match the patients cellular structure. However, cord blood cells can adapt to a wide variety of patients, and dont require donor matching. Chances for graft-versus-host disease are also much lower for cord blood transplants.

Patients and doctors can avoid graft-versus-host disease, and other dangerous side effects, by using HLA matching.

Multipotent stem cells develop into organ system cells, and are made from two different types of cells:

HSCs can become any type of blood cell or cellular blood component inside the body, including white blood cells and red blood cells. These cells are found in umbilical cord blood and are multipotent, which means they can develop into more than one cell type.

This cell type has been used in over 1 million patient transplants around the world.

MSCs can turn into bone, cartilage, fat tissue, and more. Although they are associated with bone marrow, these cells are also found in umbilical cord blood. These cells can function as connective tissue, which connects vital organs inside the body. Like HSCs, MSCs are multipotent.

Pluripotent cells can replace any type of cellular system in the body. Cord blood contains a rich variety of pluripotent stem cells, which allows treatment for a large amount of patients.

iPS cells are artificially-made pluripotent stem cells. This technique allows medical staff to create additional pluripotent cells, which will increase treatment options for patients using stem cell therapy in the near future.

ES cells are pluripotent, and similar to iPS cells, but come from an embryo. However, this kills the fertilized baby inside the embryo. This type of cell also has a high chance for graft-versus-host disease, when transplanted cells attack the patients body.

Your adult cells have one disadvantage to cord blood cells they cannot change their cell type. When stem cells from cord blood and tissue are transplanted, they adjust to fit the individual patient and replace damaged cells. Adult stem cells are also older, which means they have been exposed to disease, and may damage patients after the transplant. Compared to cord blood cells, adult cells have a higher chance for graft-versus-host disease.

Cord blood contains a wide variety of cell types, but there are different stem cell sources available to patients in need of a transplant.

Bone Marrow for Spine and Orthopaedic Stem Cell Treatment …

By Dr. Matthew Watson

Stem cells are the next frontier in the treatment of orthopaedic and spinal disorders, and the Cary Orthopaedics team is leading the way.

Using stem cells harvested from an adult patients own bone marrow,Dr. Sameer Mathurand Dr. Nael Shanti both board-certified orthopaedic spinal surgeons have developed a minimally invasive remedy for those suffering from degenerative disc disease, back pain and spinal arthritis. Applying a similar approach, Cary OrthosDr. Douglas Martini a fellowship-trained, board-certified orthopaedic surgeon specializing in sports medicine has crafted a pain-relief solution for patients living with osteoarthritis and soft tissue injuries.

Multiple research studies have shown a significant reduction in low back and joint pain and improved function after stem cell injections. While these treatments are new, 80% to 90% of patients are already reporting improvement in their symptoms after orthopaedic stem cell treatments.

Many patients suffering from degenerative disc diseases or low back pain are often not ideal candidates for surgery, and some who have chosen to undergo surgery have had unsatisfactory results. Therefore, the typical remedy for chronic orthopaedic conditions is extensive physical therapy combined with oral anti-inflammatory medications. The result: The majority of patients still had to live with pain.

Physicians at Cary Orthopaedics are utilizing orthopaedic stem cell treatment using the patients own bone marrow, the soft, spongy tissue found in the center of bones. Bone marrow in adults contains a rich reservoir of multipotent stem cells also known as Mesenchymal Precursor Cells (MPCs) that can be extracted from the patients pelvis or hip bone. Due to their unique, regenerative composition, these cells can become various types of tissues including soft tissue, bone or cartilage, which make them an excellent resource for repairing and rebuilding damaged tissue, accelerating the healing process and improving overall function.

Thanks to advancements in technology, the removal and harvesting process has become easier and less expensive. Since this is a minimally invasive procedure, it has fewer side effects compared to traditional surgery, and it causes minimal discomfort to the patient.

Bone marrow injections are a breakthrough for patients in pain. Dr. Martini, a sports medicine physician at Cary Orthopaedics, has been active in the sports medicine community, previously serving as team physician for the Carolina Hurricanes, numerous colleges, and local high schools. After 25 years of experience in sports medicine, he realizes the need for improved treatment options for the greying athlete. He has begun incorporating bone marrow aspirate concentrate (BAC) into the treatment of both acute and chronic soft tissue and joint-related injuries. I believe this will be equally helpful to the patient who needs to exercise for overall health benefits as it would be for those who need to stay at their peak athletic performance, says Dr. Martini.

We have found based on our research and experience that stem cell therapy can be very safe and effective when used with the appropriate patient population, said Kevin G. Morrison, PA-C, a member of Dr. Martinis team. All the feedback to this point has been quite positive, both on the process of having the procedure done as well as the early response. But ultimately long-term data will need to be compiled and critically examined.

Much of the previous research into stem cells has centered around placental stem cells, which can also adapt into other types of tissues. However, these have not performed well when put to the test for orthopaedic treatment. Bone marrow aspirate concentrate provides MPCs that can transform into osteocytes, chondrocytes and adipocytes, all of which are important in treating orthopedic conditions.

The latest research around mesenchymal stem cells, specifically bone marrow aspiration, is certainly promising. Dr. Martini will continue to collect more data and review patients responses.

Dr. Mathur has been an instrumental force in elevating the level of patient care at Cary Orthopaedic Spine Center since joining the practice in 2008. Dr. Mathur completed his medical school at the University of Pennsylvania and spinal reconstructive fellowship at the Rush University Medical Center in Chicago. He also taught at Dana Farber Cancer Institute in Boston. Over the last 10 years, in conjunction with the National Institutes of Health, he has conducted significant study of disc degeneration and analysis of the expression of genes that may damage the disc.

In the past decade, there have been several advancements in spinal surgery, but regenerative medicine is the next frontier, said Dr. Mathur. I see so many patients that have low back pain and leg pain from degenerative disc disease. For many, there is no good surgical treatment, and stem cell injections may be a viable option.

As an orthopaedic spine specialist, Dr. Mathur is not only an expert in spinal surgery but also in the diagnosis and treatment of a wide range of spinal problems. His depth of experience allows him to best determine whether a patient would benefit from physical therapy, stem cell injections or surgical intervention. When providing stem cell treatment, Dr. Mathur performs a single injection for all patients, whereas other clinics typically require multiple injections over several weeks.

There is currently extensive, ongoing research on the application of stem cell therapy and tissue regeneration, including an application for spinal cord injury and disc pathology, which is very exciting, said Dr. Shanti, who has dedicated a great deal of time researching the potential impact stem cell therapy can provide for his patients. Dr. Shanti believes stem cell therapy is the next great advancement in healthcare with an application for a wide spectrum of medical conditions.

Recently recognized as Top Orthopaedic Doctor by The Leading Physicians of the World for the outstanding patient care, Dr. Shantis in-depth experience and understanding of the spine allows him to guide his patients especially those with chronic back pain to the most appropriate path of treatment with the shared collaborative goal of pain relief. Dr. Shanti completed his spine surgery fellowship training at the prestigious New England Baptist Hospital, Tufts University program with an emphasis on minimally invasive spine surgery, and he has authored and presented multiple papers and textbooks on the advancement of minimally invasive spine surgery.

Orthopaedic stem cell treatment is an excellent solution for patients with degenerative disc disease and also those suffering from arthritis of the spine, bulging disc, low back pain, facet joint pain or disc with annular tears.

The stem cell injection is a same-day procedure that generally takes one hour to perform. The actual extraction of bone marrow takes up to 10 minutes. The bone marrow extraction site typically the back of the patients hip or pelvis bone is numbed using a mixture of local anesthetics. A suctioned syringe is attached to a long needle that reaches the posterior aspect of the hip. The patient may experience a minimal amount of discomfort during the extraction.

The sample is collected, transferred through a filter, and then placed into a centrifuge for spinning. The speed separates the stem cells and platelets from the bone marrow. This concentration of stem cells is then reintroduced into the degenerative or painful area under image guidance with fluoroscopy to confirm accurate placement.

The harvesting site will be numb for 1 to 2 hours after the procedure, so the patient will need to have transportation home. It is permissible to fly after the treatment, but this may cause increased pain or discomfort.

Stem cell therapy relies on the bodys own regenerative process to heal, which takes time. Patients have seen the benefits in two to three months after treatment; however, many have noticed improvements in symptoms sooner.

The recommended age range for the treatment is 20 to 70 years old. As the body ages, the quality and quantity of stem cells slowly decline. After age 70, patients may experience a sharper decline in stem cells, resulting in less beneficial outcomes.

If you think you might be a candidate for orthopaedic stem cell therapy treatment, contact Cary Orthopaedics to schedule a consultation.

Become a Donor | The Bone Marrow Foundation

By Dr. Matthew Watson

Jack, diagnosed with Acute Myelogenous Leukemia (AML), and his donor Kristy

To become a donor it just takes a small vial of blood or swab of cheek cells to be typed as a bone marrow/stem cell donor. There are many patients who are desperately waiting to find a donor match. You may be able to save someones life. There are donor registry sites throughout the country.

You must be between the ages of 18 and 60 and in general good health. You should be committed to helping any patient. A simple blood test or cheek cell swab that is given through an authorized National Marrow Donor Program Donor Center or Recruitment Group is needed to obtain your HLA tissue type so it can be entered into the National Registry. You will have to complete a short health questionnaire and sign a form stating that you understand what it means to be listed in the Registry.

The cost for HLA tissue typing ranges from $45 to $96 depending on the Donor Center, the level of testing performed, and the laboratory that analyzes the test results. There may be funding available to offset this cost through the Donor Center. After the initial testing, all medical expenses are covered by the recipient or the recipients insurance. Please contact your local Donor Center for further information.

Every 15 minutes, someone in the United States is diagnosed with a medical condition (over 35,000 people a year) such as leukemia, anemias, myelodysplastic disorders and other life-threatening diseases that require treatment with bone marrow/stem cell transplants. Nearly 70 percent of these patients must rely on an unrelated donor to offer them this precious gift of life. Unfortunately, many patients who are in need of a bone marrow/stem cell transplant cannot find a suitable donor no relatives that match and no match among volunteer donors.

Fortunately, there is an alternative that has been researched and is now proving to be a good option for many of these patientsstem cells from a newborns placental and umbilical cord blood. A newborns umbilical cord and placenta contains stem cells that are the building blocks for mature blood and immune system cells. Umbilical cord blood is collected at the time of birth under controlled conditions, shipped to a blood bank where it is tested, typed and stored.

Two studies published in The New England Journal of Medicine, Volume 351:2276-285 and an editorial by Miguel A. Sanz, M.D., Ph.D. in the same issue, concluded that cord blood should be considered as an acceptable source of stem cells in the absence of a matched bone marrow donor. For many gravely ill patients (who do not have an available donor who is a match), the immediate availability of typed cord blood units is a compelling reason for its use. And for ethnic minorities, who may have unique combinations of HLA types, the chances of finding a donor match with cord blood is greater than from the existing bone marrow donor pool.

If you have a family history of certain diseases you might choose to save your babys cord blood with a private bank. Alternatively, you can donate the cord blood to a public bank. The Bone Marrow Foundation encourages you to direct any questions you have concerning the use and storage of cord blood to your physician or other appropriate health care professional.

What is BMC, Bone Marrow Stem Cell Therapy?

By Dr. Matthew Watson

Bone Marrow Concentrate (BMC) Therapy, also known as Bone Marrow Aspirate Concentrate (BMAC) Therapy, is a promising cutting-edge regenerative therapy to help accelerate healing in moderate to severe osteoarthritis and tendon injuries. While similar to Platelet Rich Plasma (PRP) in its ability to harness the bodys ability to heal itself through the aid of growth factors, BMC also utilizes regenerative cells that are contained within a patients own bone marrow. The marrow contains a rich reservoir of pluripotent stem cells that can be withdrawn from the patients hip bone and used for the procedure. Unlike other cells of the body, stem cells are undifferentiated, meaning they are able to replicate themselves into various types of tissue.

In the past, the process of removing and harvesting these cells was often difficult and expensive. With recent medical advancements in both the aspiration of the bone marrow and harvesting of the regenerative cells, the procedure can be done with minimal discomfort and patients are sent home the same day. The process is relatively simple. The patient is first numbed using a mixture of local anesthetics. Under the guidance of an X-Ray machine, the physician then removes a small amount of the patients bone marrow from the hip bone which is then placed into a centrifuge to separate the regenerative cells and platelets from the rest of the blood products. The final product is a concentrate which has approximately 5-10 times the baseline levels of regenerative cells and growth factors. This point of care treatment allows for minimal manipulation of cells which are then injected to the injured area. The entire process takes approximately 2 hours and patients go home the same day.

How Bone Marrow and Stem Cells are Collected | BMT Infonet

By Dr. Matthew Watson

Language English

If you are providing the blood stem cells for a transplant, they will either be collected from your bloodstream (peripheral blood) or from your bone marrow.

The largest concentration of blood stem cells is in your bone marrow. However, the blood stem cells can be moved or "mobilized" out of the bone marrow into the bloodstream (peripheral blood) where they can be easily collected. Most transplants these days use stem cells collected from the bloodstream.

When blood stem cells are collected from the bloodstream, the procedure is called a peripheral blood stem cell collection or harvest.

Prior to the harvest, you will receive injections of a drug such as filgrastim (Neupogen) or plerixifor (Mozobil) over a four to five day period. These drugs move stem cells out of the bone marrow into the bloodstream.

Most people tolerate these drugs well, although mild, flu-like symptoms are common. The symptoms end a few days after the injections stop.

If you are collecting stem cells for your own transplant, chemotherapy drugs may be used to help move the stem cells out of your bone marrow into the bloodstream.

Peripheral blood stem cell collections are done in an outpatient clinic.

The procedure is painless. However, you may feel lightheaded, cold or numb around the lips. Some people feel cramping in their hands which is caused by the blood thinning agent used during the procedure. These symptoms cease when the procedure ends.

The procedure used to collect bone marrow for transplant is called a bone marrow harvest. It is a surgical procedure that takes place in a hospital operating room. Typically it is done as an outpatient procedure.

The amount of bone marrow harvested depends on the size of the patient and the concentration of blood stem cells in your marrow.

Typically one to two quarts of marrow and blood are harvested. While this may sound like a lot, your body can usually replace it in four weeks.

When the anesthesia wears off, you may feel some discomfort in your hip and lower back for several days. The pain is similar to what you would feel if you took a hard fall and bruised your hip. You may find sitting for a long period of time or climbing stairs uncomfortable for a few days. The pain is usually relieved with acetaminophen (Tylenol).

Bone marrow suppression – Wikipedia

By Dr. Matthew Watson

Bone marrow suppressionSynonymMyelotoxicity, myelosuppression

Bone marrow suppression also known as myelotoxicity or myelosuppression, is the decrease in production of cells responsible for providing immunity (leukocytes), carrying oxygen (erythrocytes), and/or those responsible for normal blood clotting (thrombocytes).[1] Bone marrow suppression is a serious side effect of chemotherapy and certain drugs affecting the immune system such as azathioprine.[2] The risk is especially high in cytotoxic chemotherapy for leukemia.

Nonsteroidal anti-inflammatory drugs (NSAIDs), in some rare instances, may also cause bone marrow suppression. The decrease in blood cell counts does not occur right at the start of chemotherapy because the drugs do not destroy the cells already in the bloodstream (these are not dividing rapidly). Instead, the drugs affect new blood cells that are being made by the bone marrow.[3] When myelosuppression is severe, it is called myeloablation.[4]

Many other drugs including common antibiotics may cause bone marrow suppression. Unlike chemotherapy the effects may not be due to direct destruction of stem cells but the results may be equally serious. The treatment may mirror that of chemotherapy-induced myelosuppression or may be to change to an alternate drug or to temporarily suspend treatment.

Because the bone marrow is the manufacturing center of blood cells, the suppression of bone marrow activity causes a deficiency of blood cells. This condition can rapidly lead to life-threatening infection, as the body cannot produce leukocytes in response to invading bacteria and viruses, as well as leading to anaemia due to a lack of red blood cells and spontaneous severe bleeding due to deficiency of platelets.

Parvovirus B19 inhibits erythropoiesis by lytically infecting RBC precursors in the bone marrow and is associated with a number of different diseases ranging from benign to severe. In immunocompromised patients, B19 infection may persist for months, leading to chronic anemia with B19 viremia due to chronic marrow suppression.[5]

Bone marrow suppression due to azathioprine can be treated by changing to another medication such as mycophenolate mofetil (for organ transplants) or other disease-modifying drugs in rheumatoid arthritis or Crohn's disease.

Bone marrow suppression due to anti-cancer chemotherapy is much harder to treat and often involves hospital admission, strict infection control, and aggressive use of intravenous antibiotics at the first sign of infection.[citation needed]

G-CSF is used clinically (see Neutropenia) but tests in mice suggest it may lead to bone loss.[6][7]

GM-CSF has been compared to G-CSF as a treatment of chemotherapy-induced myelosuppression/Neutropenia.[8]

In developing new chemotherapeutics, the efficacy of the drug against the disease is often balanced against the likely level of myelotoxicity the drug will cause. In-vitro colony forming cell (CFC) assays using normal human bone marrow grown in appropriate semi-solid media such as ColonyGEL have been shown to be useful in predicting the level of clinical myelotoxicity a certain compound might cause if administered to humans.[9] These predictive in-vitro assays reveal effects the administered compounds have on the bone marrow progenitor cells that produce the various mature cells in the blood and can be used to test the effects of single drugs or the effects of drugs administered in combination with others.

What is a Bone Marrow Transplant (Stem Cell Transplant …

By Dr. Matthew Watson

A bone marrow transplant, also called a stem cell transplant, is a treatment for some types of cancer. For example, you might have one if you have leukemia, multiple myeloma, or some types of lymphoma. Doctors also treat some blood diseases with stem cell transplants.

In the past, a stem cell transplant was more commonly called a bone marrow transplant because the stem cells were collected from the bone marrow. Today, stem cells are usually collected from the blood, instead of the bone marrow. For this reason, they are now often called stem cell transplants.

A part of your bones called bone marrow makes blood cells. Marrow is the soft, spongy tissue inside bones. It contains cells called hematopoietic stem cells (pronounced he-mah-tuh-poy-ET-ick). These cells can turn into several other types of cells. They can turn into more bone marrow cells. Or they can turn into any type of blood cell.

Certain cancers and other diseases keep hematopoietic stem cells from developing normally. If they are not normal, neither are the blood cells that they make. A stem cell transplant gives you new stem cells. The new stem cells can make new, healthy blood cells.

The main types of stem cell transplants and other options are discussed below.

Autologous transplant. This is also called an AUTO transplant or high-dose chemotherapy with autologous stem cell rescue.

In an AUTO transplant, you get your own stem cells after doctors treat the cancer. First, your health care team collects stem cells from your blood and freezes them. Next, you have powerful chemotherapy, and rarely, radiation therapy. Then, your health care team thaws your frozen stem cells. They put them back in your blood through a tube placed in a vein (IV).

It takes about 24 hours for your stem cells to reach the bone marrow. Then they start to grow, multiply, and help the marrow make healthy blood cells again.

Allogeneic transplantation. This is also called an ALLO transplant.In an ALLO transplant, you get another persons stem cells. It is important to find someone whose bone marrow matches yours. This is because you have certain proteins on your white blood cells called human leukocyte antigens (HLA). The best donor has HLA proteins as much like yours as possible.

Matching proteins make a serious condition called graft-versus-host disease (GVHD) less likely. In GVHD, healthy cells from the transplant attack your cells. A brother or sister may be the best match. But another family member or volunteer may also work.

Once you find a donor, you receive chemotherapy with or without radiation therapy. Next, you get the other persons stem cells through a tube placed in a vein (IV). The cells in an ALLO transplant are not typically frozen. This way, your doctor can give you the cells as soon as possible after chemotherapy or radiation therapy.

There are 2 types of ALLO transplants. The best type for each person depends on his or her age, health, and the type of disease being treated.

Ablative, which uses high-dose chemotherapy

Reduced intensity, which uses milder doses of chemotherapy

If your health care team cannot find a matched adult donor, there are other options. Research is ongoing to determine which type of transplant will work best for different people.

Umbilical cord blood transplant. This may be an option if you cannot find a donor match. Cancer centers around the world use cord blood.

Parent-child transplant and haplotype mismatched transplant. These types of transplants are being used more often. The match is 50%, instead of near 100%. Your donor might be a parent, child, brother, or sister.

Your doctor will recommend an AUTO or ALLO transplant based mostly on the disease you have. Other factors include the health of your bone marrow and your age and general health. For example, if you have cancer or other disease in your bone marrow, you will probably have an ALLO transplant. In this situation, doctors do not recommend using your own stem cells.

Choosing a transplant is complicated. You will need help from a doctor who specializes in transplants. You might need to travel to a center that does many stem cell transplants. Your donor might also need to go. At the center, you will talk with a transplant specialist and have an examination and medical tests.

Before a transplant, you should also think about non-medical factors. These include:

Who can care for you during treatment

How long you will be away from work and family responsibilities

If your insurance pays for the transplant

Who can take you to transplant appointments

Your health care team can help you find answers to these questions.

The information below tells you the main parts of AUTO and ALLO transplants. Your health care team usually does the steps in order. But sometimes certain steps happen in advance, such as collecting stem cells. Ask your health care team what to expect before, during, and after a transplant.

Part 1: Collecting your stem cells

During this part, you get injections of a medication to raise your number of stem cells.Your doctor may collect stem cells through your veins using standard IVs or a catheter, which is placed in a large vein in the chest. This stays in place throughout your stay at the hospital. The catheter is used to give chemotherapy, other medications, and blood transfusions.

Time: Several days

Where it is done: Clinic or hospital building. You do not need to stay in the hospital overnight.

Part 2: Transplant treatment

You get high doses of chemotherapy, and rarely, radiation therapy.

Time: 5 to 10 days

Where it is done: A clinic or hospital. At many transplant centers, people need to stay in the hospital for the duration of the transplant, usually about 3 weeks. At some centers, a person receives treatment in the clinic and can come in every day.

Part 3: Getting your stem cells back

This part is called the stem cell infusion. Your health care team puts your stem cells back in your blood through the transplant catheter.

Time: Each infusion usually takes less than 30 minutes. You may receive more than 1 infusion.

Where it is done: A clinic or hospital.

Part 4: Recovery

You take antibiotics and other drugs. You get blood transfusions through your transplant catheter, if needed. This is also when your health care team helps with any transplant side effects.

Time: Approximately 2 weeks

Where it is done: A clinic or hospital. You might be staying in the hospital.

Part 1: Collecting stem cells from your donor

During this part, the health care team gives your donor injections of a medication to increase white cells in the blood, if the cells are collected from blood. Some donors will donate bone marrow in the operating room during a procedure which takes several hours.

Time: Varies based on how the stem cells are collected

Where it is done: A clinic or hospital

Part 2: Transplant treatment

You get chemotherapy with or without radiation therapy.

Time: 5 to 7 days

Where it is done: Many ALLO transplants are done in the hospital.

Part 3: Getting the donor cells

This part is called the stem cell infusion. Your health care team puts the donors stem cells in your blood through the transplant catheter. It takes less than 1 hour. The transplant catheter stays in until after treatment.

Time: 1 day

Where it is done: A clinic or hospital

Part 4: Recovery

During the recovery, you receive antibiotics and other drugs. This includes medications to prevent graft-versus-host disease. If needed, you get blood transfusions through your catheter. This is also when your health care team takes care of any side effects from the transplant.

After the transplant, people visit the clinic frequently at first and less often over time.

Time: It varies.For an ablative transplant, people are usually in the hospital for about 4 weeks in total.For a reduced intensity transplant, people are in the hospital or visit the clinic daily for about a week.

The words successful transplant might mean different things to you, your family, and your health care team. Below are 2 ways to measure transplant success: Your blood counts are back to safe levels. A blood count is the number of red cells, white cells, and platelets in your blood. A transplant makes these numbers very low for 1 to 2 weeks. This causes risks of:

Infection from low numbers of white cells, which fight infections

Bleeding from low numbers of platelets, which stop bleeding

Tiredness from low numbers of red cells, which carry oxygen

Doctors lower these risks by giving blood and platelet transfusions after a transplant. You also take antibiotics to help prevent infections. When the new stem cells multiply, they make more blood cells. Then your blood counts improve. This is one way to know if a transplant is a success.

It controls your cancer. Doctors do stem cell transplants with the goal of curing disease. A cure may be possible for some cancers, such as some types of leukemia and lymphoma. For other people, remission is the best result. Remission is having no signs or symptoms of cancer. After a transplant, you need to see your doctor and have tests to watch for any signs of cancer or complications from the transplant.

Talking often with your health care team is important. It gives you information to make decisions about your treatment and care. The following questions may help you learn more about stem cell transplant:

Which type of stem cell transplant would you recommend? Why?

If I will have an ALLO transplant, how will we find a donor? What is the chance of a good match?

What type of treatment will I have before the transplant? Will radiation therapy be used?

How long will my treatment take? How long will I stay in the hospital?

How will a transplant affect my life? Can I work? Can I exercise and do regular activities?

How will we know if the transplant works?

What if the transplant does not work? What if the cancer comes back?

What are the short-term side effects that may happen during treatment or shortly after?

What are the long-term side effects that may happen years later?

What tests will I need later? How often will I need them?

If I am worried about managing the costs of treatment, who can help me with these concerns?

Stem cell and bone marrow transplants – NHS

By Dr. Matthew Watson

A stem cell or bone marrow transplant replaces damaged blood cells with healthy ones. It can be used to treat conditions affecting the blood cells, such as leukaemia and lymphoma.

Stem cells arespecial cells produced bybone marrow (aspongytissue found in the centre of some bones) that can turn into different types of blood cells.

The 3 maintypes of blood cellthey can become are:

A stem cell transplant involves destroying any unhealthy blood cells and replacing them with stem cells removed from the blood or bone marrow.

Stem cell transplants are used to treat conditions in which the bone marrow is damaged and is no longer able to produce healthy blood cells.

Transplants can also be carried out to replace blood cells that are damaged or destroyed as a result of intensive cancer treatment.

Conditions that stem cell transplants can be used to treat include:

A stem cell transplant will usually only be carried out if other treatments haven't helped, the potential benefits of a transplant outweigh the risks and you're in relatively good health, despite your underlying condition.

A stem cell transplant can involve taking healthy stem cells from the blood or bone marrow of one person ideally a close family member with the same or similar tissue type (see below) and transferring them to another person. This is called an allogeneic transplant.

It's also possible to remove stem cells from your own body and transplant them later, after any damaged or diseased cells have been removed. This is called an autologous transplant.

Astem celltransplant has 5 main stages. These are:

Having a stem cell transplant can be an intensive and challenging experience. You'll usually need to stay in hospital fora month or more until the transplant starts to take effect and itcan takea year or 2 to fully recover.

Read more about what happens during a stem cell transplant.

Stem celltransplants arecomplicated procedures with significant risks. It's important that you're aware of both the risks and possible benefits before treatment begins.

Possible problems that can occur during or after the transplant process include:

Read more about the risks of having a stem cell transplant.

Ifit isn't possible to use your own stem cells for the transplant (see above), stem cells will need to come from a donor.

To improve the chances ofthetransplant being successful, donated stem cells need tocarry a special genetic marker known as a human leukocyte antigen (HLA) that'sidentical or very similar to that of the person receiving the transplant.

The best chance of getting a match is from a brother or sister, or sometimes another close family member. If there are no matches in your close family,a search of theBritish Bone Marrow Registry will be carried out.

Most peoplewill eventually find a donor in the registry,although a small number of people may find it very hard or impossibleto find a suitable match.

The NHS Blood and Transplant website and the Anthony Nolan website have more information about stem cell and bone marrow donation.

Bone Marrow & Stem Cell Transplant | IU Health

By Dr. Matthew Watson

To prepare your body for bone marrow or stem cell transplant, youll be treated with high doses of chemotherapy with or without radiation to destroy cancerous cells. Some healthy cells may also be destroyed, which can cause unpleasant side effects. These side effects typically go away after a few weeks.

Once this preparation is complete, new stem cells will be transplanted through your veins and the cells will make their way to your bone marrow. These stem cells will mature into healthy marrow, to produces healthy blood and immune cells.

Stem cells transplants can come from your own bone marrow (autologous) or a donors marrow (allogeneic). Whether autologous or allogeneic stem cells are used depends on your condition, and the procedures have some differences.

Uses your own stem cells. Before chemotherapy, your stem cells are collected by apheresis, frozen with a preservative and stored until they are needed. Because the cells are yours, theres no risk of your body rejecting the transplanted stem cells. This method is appropriate for blood-related cancers like multiple myeloma, non-Hodgkin lymphomas and Hodgkin disease, as well as certain germ-cell cancers.

Use healthy cells from a donor, when an immunological effect is needed to fight your cancer. Your donor will usually be a sibling or a strong match from the national registry. If a matched sibling or unrelated donor cannot be found, cord blood stem cells or a mismatched relative donor may be used.

The donors stem cells are collected by apheresis or from the bone marrow in a surgical procedure. Youll need to take medicines to suppress your immune system to prevent rejection and keep the donors immune cells from attacking your normal cells. Donor-cell transplant is used to treat blood-related cancers like leukemias and some lymphomas or multiple myeloma, and bone marrow failure disorders like myelodysplastic syndrome and aplastic anemia.

How Bone Marrow and Stem Cell Transplants Work

By JoanneRUSSELL25

If you or a loved one will be having a bone marrow transplant or donating stem cells, what does it entail? What are the different types of bone marrow transplants and what is the experience like for both the donor and recipient?

A bone marrow transplant is a procedure in which when special cells (called stem cells) are removed from the bone marrow or peripheral blood, filtered and given back either to the same person or to another person.

Since we now derive most stem cells needed from the blood rather than the bone marrow, a bone marrow transplant is now more commonly referred to as stem cell transplant.

Bone marrow is found in larger bones in the body such as the pelvic bones. This bone marrow is the manufacturing site for stem cells. Stem cells are "pluripotential" meaning that the cells are the precursor cells which can evolve into the different types of blood cells, such as white blood cells, red blood cells, and platelets.

If something is wrong with the bone marrow or the production of blood cells is decreased, a person can become very ill or die. In conditions such as aplastic anemia, the bone marrow stops producing blood cells needed for the body. In diseases such as leukemia, the bone marrow produces abnormal blood cells.

The purpose of a bone marrow transplant is thus to replace cells not being produced or replace unhealthy stem cells with healthy ones. This can be used to treat or even cure the disease.

In addition to leukemias, lymphomas, and aplastic anemia, stem cell transplants are being evaluated for many disorders, ranging from solid tumors to other non-malignant disorders of the bone marrow, to multiple sclerosis.

There are two primary types of bone marrow transplants, autologous and allogeneic transplants.

The Greek prefix "auto" means "self." In an autologous transplant, the donor is the person who will also receive the transplant. This procedure, also known as a "rescue transplant" involves removing your stem cells and freezing them. You then receive high dose chemotherapy followed by infusion of the thawed out frozen stem cells. It may be used to treat leukemias, lymphomas, or multiple myeloma.

The Greek prefix "allo" means "different" or "other." In an allogeneic bone marrow transplant, the donor is another person who has a genetic tissue type similar to the person needing the transplant. Because tissue types are inherited, similar to hair color or eye color, it is more likely that you will find a suitable donor in a family member, especially a sibling. Unfortunately, this occurs only 25 to 30 percent of the time.

If a family member does not match the recipient, the National Marrow Donor Program Registry database can be searched for an unrelated individual whose tissue type is a close match. It is more likely that a donor who comes from the same racial or ethnic group as the recipient will have the same tissue traits. Learn more about finding a donor for a stem cell transplant.

Bone marrow cells can be obtained in three primary ways. These include:

The majority of stem cell transplants are done using PBSC collected by apheresis (peripheral blood stem cell transplants.) This method appears to provide better results for both the donor and recipient. There still may be situations in which a traditional bone marrow harvest is done.

Donating stem cells or bone marrow is fairly easy. In most cases, a donation is made using circulating stem cells (PBSC) collected by apheresis. First, the donor receives injections of a medication for several days that causes stem cells to move out of the bone marrow and into the blood. For the stem cell collection, the donor is connected to a machine by a needle inserted in the vein (like for donating blood). Blood is taken from the vein, filtered by the machine to collect the stem cells, then returned back to the donor through a needle in the other arm. There is almost no need for a recovery time with this procedure.

If stem cells are collected by bone marrow harvest (much less likely), the donor will go to the operating room and while asleep under anesthesia and a needle will be inserted into either the hip or the breastbone to take out some bone marrow. After awakening, there may be some pain where the needle was inserted.

A bone marrow transplant can be a very challenging procedure for the recipient.

The first step is usually receiving high doses of chemotherapy and/or radiation to eliminate whatever bone marrow is present. For example, with leukemia, it is first important to remove all of the abnormal bone marrow cells.

Once a person's original bone marrow is destroyed, the new stem cells are injected intravenously, similar to a blood transfusion. The stem cells then find their way to the bone and start to grow and produce more cells (called engraftment).

There are many potential complications. The most critical time is usually when the bone marrow is destroyed so that few blood cells remain. Destruction of the bone marrow results in greatly reduced numbers of all of the types of blood cells (pancytopenia). Without white blood cells there is a serious risk of infection, and infection precautions are used in the hospital (isolation). Low levels of red blood cells (anemia) often require blood transfusions while waiting for the new stem cells to begin growing. Low levels of platelets (thrombocytopenia) in the blood can lead to internal bleeding.

A common complication affecting 40 to 80 percent of recipients is graft versus host disease. This occurs when white blood cells (T cells) in the donated cells (graft) attack tissues in the recipient (the host), and can be life-threatening.

An alternative approach referred to as a non-myeloablative bone marrow transplant or "mini-bone marrow transplant" is somewhat different. In this procedure, lower doses of chemotherapy are given that do not completely wipe out or "ablate" the bone marrow as in a typical bone marrow transplant. This approach may be used for someone who is older or otherwise might not tolerate the traditional procedure. In this case, the transplant works differently to treat the disease as well. Instead of replacing the bone marrow, the donated marrow can attack cancerous cells left in the body in a process referred to as "graft versus malignancy."

If you'd like to become a volunteer donor, the process is straightforward and simple. Anyone between the ages of 18 and 60 and in good health can become a donor. There is a form to fill out and a blood sample to give; you can find all the information you need at the National Marrow Donor Programwebsite. You can join a donor drive in your area or go to a local Donor Center to have the blood test done.

When a person volunteers to be a donor, his or her particular blood tissue traits, as determined by a special blood test (histocompatibility antigen test,) are recorded in the Registry. This "tissue typing" is different from a person's A, B, or O blood type. The Registry record also contains contact information for the donor, should a tissue type match be made.

Bone marrow transplants can be either autologous (from yourself) or allogeneic (from another person.) Stem cells are obtained either from peripheral blood, a bone marrow harvest or from cord blood that is saved at birth.

For a donor, the process is relatively easy. For the recipient, it can be a long and difficult process, especially when high doses of chemotherapy are needed to eliminate bone marrow. Complications are common and can include infections, bleeding, and graft versus host disease among others.

That said, bone marrow transplants can treat and even cure some diseases which had previously been almost uniformly fatal. While finding a donor was more challenging in the past, the National Marrow Donor Program has expanded such that many people without a compatible family member are now able to have a bone marrow/stem cell transplant.

Bone Marrow-Derived Stem Cell Therapy Milwaukee, WI …

By LizaAVILA

Advanced Therapy with Advanced Results

Since 1968, the medical community has been harnessing the incredible healing, and regenerative power of bone marrow-derived stem cells. Bone Marrow Derived Stem Cell Therapy takes stem cells isolated from your bone marrow and relocates them to heal, regenerate and treat damaged areas and chronic conditions. This revolutionary technology is a result of decades of evidence-based research and advancements in the area of stem cells.

A process called hematopoiesis, which occurs inside your bones, has been working to grow and regenerate cells in your body since you were in the womb. The human body is in constant high demand for blood cells, so the hematopoiesis process stays hard at work to produce. During hematopoiesis, hematopoietic stem cells are produced with the raw potential power to develop into white blood cells, red blood cells, and platelets. Blood cells are vital to immune function and healing, so these stem cells are rich in growth factors that facilitate the repair and replacement of damaged cells. Mesenchymal stem cells are also found in bone marrow. Mesenchymal stem cells are reserved adult stem cells that help facilitate the regeneration of tissue naturally in the body. They are an integral part of wound healing, regulation of aging, and stabilizing vital organs. These mesenchymal stem cells are considered to be raw potential meaning they can differentiate into the tissue cells needed in a specific area. These mesenchymal stem cells have the potential to repair damaged cartilage, bone, tendons, muscle, skin, and connective cell tissue.

Stem cell therapy is one of the newest and most cutting-edge therapies for chronic joint pain. Using this therapy, our providers offer patients essential properties for healing and restoring joint health:

Bone marrow transplant – Mayo Clinic

By raymumme

Overview

A bone marrow transplant is a procedure that infuses healthy blood stem cells into your body to replace your damaged or diseased bone marrow. A bone marrow transplant is also called a stem cell transplant.

A bone marrow transplant may be necessary if your bone marrow stops working and doesn't produce enough healthy blood cells.

Bone marrow transplants may use cells from your own body (autologous transplant) or from a donor (allogeneic transplant).

Mayo Clinic's approach

A bone marrow transplant may be used to:

Bone marrow transplants can benefit people with a variety of both cancerous (malignant) and noncancerous (benign) diseases, including:

Bone marrow is the spongy tissue inside some bones. Its job is to produce blood cells. If your bone marrow isn't functioning properly because of cancer or another disease, you may receive a stem cell transplant.

To prepare for a stem cell transplant, you receive chemotherapy to kill the diseased cells and malfunctioning bone marrow. Then, transplanted blood stem cells are put into your bloodstream. The transplanted stem cells find their way to your marrow, where ideally they begin producing new, healthy blood cells.

A bone marrow transplant poses many risks of complications, some potentially fatal.

The risk can depend on many factors, including the type of disease or condition, the type of transplant, and the age and health of the person receiving the transplant.

Although some people experience minimal problems with a bone marrow transplant, others may develop complications that may require treatment or hospitalization. Some complications could even be life-threatening.

Complications that can arise with a bone marrow transplant include:

Your doctor can explain your risk of complications from a bone marrow transplant. Together you can weigh the risks and benefits to decide whether a bone marrow transplant is right for you.

If you receive a transplant that uses stem cells from a donor (allogeneic transplant), you may be at risk of developing graft-versus-host disease (GVHD). This condition occurs when the donor stem cells that make up your new immune system see your body's tissues and organs as something foreign and attack them.

Many people who have an allogeneic transplant get GVHD at some point. The risk of GVHD is a bit greater if the stem cells come from an unrelated donor, but it can happen to anyone who gets a bone marrow transplant from a donor.

GVHD may happen at any time after your transplant. However, it's more common after your bone marrow has started to make healthy cells.

There are two kinds of GVHD: acute and chronic. Acute GVHD usually happens earlier, during the first months after your transplant. It typically affects your skin, digestive tract or liver. Chronic GVHD typically develops later and can affect many organs.

Chronic GVHD signs and symptoms include:

You'll undergo a series of tests and procedures to assess your general health and the status of your condition, and to ensure that you're physically prepared for the transplant. The evaluation may take several days or more.

In addition, a surgeon or radiologist will implant a long thin tube (intravenous catheter) into a large vein in your chest or neck. The catheter, often called a central line, usually remains in place for the duration of your treatment. Your transplant team will use the central line to infuse the transplanted stem cells and other medications and blood products into your body.

If a transplant using your own stem cells (autologous transplant) is planned, you'll undergo a procedure called apheresis (af-uh-REE-sis) to collect blood stem cells.

Before apheresis, you'll receive daily injections of growth factor to increase stem cell production and move stem cells into your circulating blood so that they can be collected.

During apheresis, blood is drawn from a vein and circulated through a machine. The machine separates your blood into different parts, including stem cells. These stem cells are collected and frozen for future use in the transplant. The remaining blood is returned to your body.

If a transplant using stem cells from a donor (allogeneic transplant) is planned, you will need a donor. When you have a donor, stem cells are gathered from that person for the transplant. This process is often called a stem cell harvest or bone marrow harvest. Stem cells can come from your donor's blood or bone marrow. Your transplant team decides which is better for you based on your situation.

Another type of allogeneic transplant uses stem cells from the blood of umbilical cords (cord blood transplant). Mothers can choose to donate umbilical cords after their babies' births. The blood from these cords is frozen and stored in a cord blood bank until needed for a bone marrow transplant.

After you complete your pretransplant tests and procedures, you begin a process known as conditioning. During conditioning, you'll undergo chemotherapy and possibly radiation to:

The type of conditioning process you receive depends on a number of factors, including your disease, overall health and the type of transplant planned. You may have both chemotherapy and radiation or just one of these treatments as part of your conditioning treatment.

Side effects of the conditioning process can include:

You may be able to take medications or other measures to reduce such side effects.

Based on your age and health history, your doctor may recommend lower doses or different types of chemotherapy or radiation for your conditioning treatment. This is called reduced-intensity conditioning.

Reduced-intensity conditioning kills some cancer cells and somewhat suppresses your immune system. Then, the donor's cells are infused into your body. Donor cells replace cells in your bone marrow over time. Immune factors in the donor cells may then fight your cancer cells.

Your bone marrow transplant occurs after you complete the conditioning process. On the day of your transplant, called day zero, stem cells are infused into your body through your central line.

The transplant infusion is painless. You are awake during the procedure.

The transplanted stem cells make their way to your bone marrow, where they begin creating new blood cells. It can take a few weeks for new blood cells to be produced and for your blood counts to begin recovering.

Bone marrow or blood stem cells that have been frozen and thawed contain a preservative that protects the cells. Just before the transplant, you may receive medications to reduce the side effects the preservative may cause. You'll also likely be given IV fluids (hydration) before and after your transplant to help rid your body of the preservative.

Side effects of the preservative may include:

Not everyone experiences side effects from the preservative, and for some people those side effects are minimal.

When the new stem cells enter your body, they begin to travel through your body and to your bone marrow. In time, they multiply and begin to make new, healthy blood cells. This is called engraftment. It usually takes several weeks before the number of blood cells in your body starts to return to normal. In some people, it may take longer.

In the days and weeks after your bone marrow transplant, you'll have blood tests and other tests to monitor your condition. You may need medicine to manage complications, such as nausea and diarrhea.

After your bone marrow transplant, you'll remain under close medical care. If you're experiencing infections or other complications, you may need to stay in the hospital for several days or sometimes longer. Depending on the type of transplant and the risk of complications, you'll need to remain near the hospital for several weeks to months to allow close monitoring.

You may also need periodic transfusions of red blood cells and platelets until your bone marrow begins producing enough of those cells on its own.

You may be at greater risk of infections or other complications for months to years after your transplant.

A bone marrow transplant can cure some diseases and put others into remission. Goals of a bone marrow transplant depend on your individual situation, but usually include controlling or curing your disease, extending your life, and improving your quality of life.

Some people complete bone marrow transplantation with few side effects and complications. Others experience numerous challenging problems, both short and long term. The severity of side effects and the success of the transplant vary from person to person and sometimes can be difficult to predict before the transplant.

It can be discouraging if significant challenges arise during the transplant process. However, it is sometimes helpful to remember that there are many survivors who also experienced some very difficult days during the transplant process but ultimately had successful transplants and have returned to normal activities with a good quality of life.

Explore Mayo Clinic studies testing new treatments, interventions and tests as a means to prevent, detect, treat or manage this disease.

Living with a bone marrow transplant or waiting for a bone marrow transplant can be difficult, and it's normal to have fears and concerns.

Having support from your friends and family can be helpful. Also, you and your family may benefit from joining a support group of people who understand what you're going through and who can provide support. Support groups offer a place for you and your family to share fears, concerns, difficulties and successes with people who have had similar experiences. You may meet people who have already had a transplant or who are waiting for a transplant.

To learn about transplant support groups in your community, ask your transplant team or social worker for information. Also, several support groups are offered at Mayo Clinic in Arizona, Florida and Minnesota.

Mayo Clinic researchers study medications and treatments for people who have had bone marrow transplants, including new medications to help you stay healthy after your bone marrow transplant.

If your bone marrow transplant is using stem cells from a donor (allogeneic transplant), you may be at risk of graft-versus-host disease. This condition occurs when a donor's transplanted stem cells attack the recipient's body. Doctors may prescribe medications to help prevent graft-versus-host disease and reduce your immune system's reaction (immunosuppressive medications).

After your transplant, it will take time for your immune system to recover. You may be given antibiotics to prevent infections. You may also be prescribed antifungal, antibacterial or antiviral medications. Doctors continue to study and develop several new medications, including new antifungal medications, antibacterial medications, antiviral medications and immunosuppressive medications.

After your bone marrow transplant, you may need to adjust your diet to stay healthy and to prevent excessive weight gain. Maintaining a healthy weight can help prevent high blood pressure, high cholesterol and other negative health effects.

Your nutrition specialist (dietitian) and other members of your transplant team will work with you to create a healthy-eating plan that meets your needs and complements your lifestyle. Your dietitian may also give you food suggestions to control side effects of chemotherapy and radiation, such as nausea.

Your dietitian will also provide you with healthy food options and ideas to use in your eating plan. Your dietitian's recommendations may include:

After your bone marrow transplant, you may make exercise and physical activity a regular part of your life to continue to improve your health and fitness. Exercising regularly helps you control your weight, strengthen your bones, increase your endurance, strengthen your muscles and keep your heart healthy.

Your treatment team may work with you to set up a routine exercise program to meet your needs. You may perform exercises daily, such as walking and other activities. As you recover, you can slowly increase your physical activity.

What is a Stem Cell Transplant (Bone Marrow Transplant)? | Cancer.Net

By Sykes24Tracey

A stem cell transplant is a treatment for some types of cancer. For example, you might have one if you have leukemia, multiple myeloma, or some types of lymphoma. Doctors also treat some blood diseases with stem cell transplants.

In the past, patients who needed a stem cell transplant received a bone marrow transplant because the stem cells were collected from the bone marrow. Today, stem cells are usually collected from the blood, instead of the bone marrow. For this reason, they are now more commonly called stem cell transplants.

A part of your bones called bone marrow makes blood cells. Marrow is the soft, spongy tissue inside bones. It contains cells called hematopoietic stem cells (pronounced he-mah-tuh-poy-ET-ick). These cells can turn into several other types of cells. They can turn into more bone marrow cells. Or they can turn into any type of blood cell.

Certain cancers and other diseases keep hematopoietic stem cells from developing normally. If they are not normal, neither are the blood cells that they make. A stem cell transplant gives you new stem cells. The new stem cells can make new, healthy blood cells.

The main types of stem cell transplants and other options are discussed below.

Autologous transplant. Doctors call this an AUTO transplant. This type of stem cell transplant may also be called high-dose chemotherapy with autologous stem cell rescue.

In an AUTO transplant, you get your own stem cells after doctors treat the cancer. First, your health care team collects stem cells from your blood and freezes them. Next, you have powerful chemotherapy, and rarely, radiation therapy. Then, your health care team thaws your frozen stem cells. They put them back in your blood through a tube placed in a vein (IV).

It takes about 24 hours for your stem cells to reach the bone marrow. Then they start to grow, multiply, and help the marrow make healthy blood cells again.

Allogeneic transplantation. Doctors call this an ALLO transplant.

In an ALLO transplant, you get another persons stem cells. It is important to find someone whose bone marrow matches yours. This is because you have certain proteins on your white blood cells called human leukocyte antigens (HLA). The best donor has HLA proteins as much like yours as possible.

Matching proteins make a serious condition called graft-versus-host disease (GVHD) less likely. In GVHD, healthy cells from the transplant attack your cells. A brother or sister may be the best match. But another family member or volunteer might work.

Once you find a donor, you receive chemotherapy with or without radiation therapy. Next, you get the other persons stem cells through a tube placed in a vein (IV). The cells in an ALLO transplant are not typically frozen. So, doctors can give you the cells as soon after chemotherapy or radiation therapy as possible.

There are 2 types of ALLO transplants. The best type for each patient depends his or her age and health and the type of disease being treated.

Ablative, which uses high-dose chemotherapy

Reduced intensity, which uses milder doses of chemotherapy

If your health care team cannot find a matched adult donor, there are other options. Research is ongoing to determine which type of transplant will work best for different patients.

Umbilical cord blood transplant. This may be an option if you cannot find a donor match. Cancer centers around the world use cord blood.

Parent-child transplant and haplotype mismatched transplant. These types of transplants are being used more commonly. The match is 50%, instead of near 100%. Your donor might be a parent, child, brother, or sister.

Your doctor will recommend an AUTO or ALLO transplant based mostly on the disease you have. Other factors include the health of your bone marrow and your age and general health. For example, if you have cancer or other disease in your bone marrow, you will probably have an ALLO transplant. In this situation, doctors do not recommend using your own stem cells.

Choosing a transplant is complicated. You will need help from a doctor who specializes in transplants. So you might need to travel to a center that does many stem cell transplants. Your donor might need to go, too. At the center, you talk with a transplant specialist and have an examination and tests. Before a transplant, you should also think about non-medical factors. These include:

Who can care for you during treatment

How long you will be away from work and family responsibilities

If your insurance pays for the transplant

Who can take you to transplant appointments

Your health care team can help you find answers to these questions.

The information below tells you the main parts of AUTO and ALLO transplants. Your health care team usually does the steps in order. But sometimes certain steps happen in advance, such as collecting stem cells. Ask your doctor what to expect before, during, and after a transplant.

A doctor puts a thin tube called a transplant catheter in a large vein. The tube stays in until after the transplant. Your health care team will collect stem cells through this tube and give chemotherapy and other medications through the tube.

You get injections of a medication to raise your number of white blood cells. White blood cells help your body fight infections.

Your health care team collects stem cells, usually from your blood.

Time: 1 to 2 weeks

Where its done: Clinic or hospital building. You do not need to stay in the hospital overnight.

Time: 5 to 10 days

Where its done: Clinic or hospital. At many transplant centers, patients need to stay in the hospital for the duration of the transplant, usually about 3 weeks. At some centers, patients receive treatment in the clinic and can come in every day.

Time: Each infusion usually takes less than 30 minutes. You may receive more than 1 infusion.

Where its done: Clinic or hospital.

Time: approximately 2 weeks

Where its done: Clinic or hospital. You might be staying in the hospital or you might not.

Time: Varies based on how the stem cells are collected

Where its done: Clinic or hospital

Time: 5 to 7 days

Where its done: Many ALLO transplants are done in the hospital.

Time: 1 day

Where its done: Clinic or hospital.

You take antibiotics and other drugs. This includes medications to prevent graft-versus-host disease. You get blood transfusions through your catheter if needed. Your health care team takes care of any side effects from the transplant.

After the transplant, patients visit the clinic frequently at first and less often over time.

Time: Varies

For an ablative transplant, patients are usually in the hospital for about 4 weeks in total.

For a reduced intensity transplant, patients are in the hospital or visit the clinic daily for about 1 week.

The words successful transplant might mean different things to you, your family, and your doctor. Below are 2 ways to measure transplant success.

Your blood counts are back to safe levels. A blood count is the number of red cells, white cells, and platelets in your blood. A transplant makes these numbers very low for 1 to 2 weeks. This causes risks of:

Infection from low numbers of white cells, which fight infections

Bleeding from low numbers of platelets, which stop bleeding

Tiredness from low numbers of red cells, which carry oxygen

Doctors lower these risks by giving blood and platelet transfusions after a transplant. You also take antibiotics to help prevent infections. When the new stem cells multiply, they make more blood cells. Then your blood counts improve. This is one way to know if a transplant is a success.

It controls your cancer. Doctors do stem cell transplants with the goal of curing disease. A cure may be possible for some cancers, such as some types of leukemia and lymphoma. For other patients, remission is the best result. Remission is having no signs or symptoms of cancer. After a transplant, you need to see your doctor and have tests to watch for any signs of cancer or complications from the transplant.

Talking often with the doctor is important. It gives you information to make health care decisions. The questions below may help you learn more about stem cell transplant. You can also ask other questions that are important to you.

Which type of stem cell transplant would you recommend? Why?

If I will have an ALLO transplant, how will we find a donor? What is the chance of a good match?

What type of treatment will I have before the transplant? Will radiation therapy be used?

How long will my treatment take? How long will I stay in the hospital?

How will a transplant affect my life? Can I work? Can I exercise and do regular activities?

How will we know if the transplant works?

What if the transplant doesnt work? What if the cancer comes back?

What are the side effects? This includes short-term, such as during treatment and shortly after. It also includes long-term, such as years later.

What tests will I need later? How often will I need them?

If I am worried about managing the costs of treatment, who can help me with these concerns?

Bone marrow | anatomy | Britannica.com

By Sykes24Tracey

Bone marrow, also called myeloid tissue, soft, gelatinous tissue that fills the cavities of the bones. Bone marrow is either red or yellow, depending upon the preponderance of hematopoietic (red) or fatty (yellow) tissue. In humans the red bone marrow forms all of the blood cells with the exception of the lymphocytes, which are produced in the marrow and reach their mature form in the lymphoid organs. Red bone marrow also contributes, along with the liver and spleen, to the destruction of old red blood cells. Yellow bone marrow serves primarily as a storehouse for fats but may be converted to red marrow under certain conditions, such as severe blood loss or fever. At birth and until about the age of seven, all human marrow is red, as the need for new blood formation is high. Thereafter, fat tissue gradually replaces the red marrow, which in adults is found only in the vertebrae, hips, breastbone, ribs, and skull and at the ends of the long bones of the arm and leg; other cancellous, or spongy, bones and the central cavities of the long bones are filled with yellow marrow.

Red marrow consists of a delicate, highly vascular fibrous tissue containing stem cells, which differentiate into various blood cells. Stem cells first become precursors, or blast cells, of various kinds; normoblasts give rise to the red blood cells (erythrocytes), and myeloblasts become the granulocytes, a type of white blood cell (leukocyte). Platelets, small blood cell fragments involved in clotting, form from giant marrow cells called megakaryocytes. The new blood cells are released into the sinusoids, large thin-walled vessels that drain into the veins of the bone. In mammals, blood formation in adults takes place predominantly in the marrow. In lower vertebrates a number of other tissues may also produce blood cells, including the liver and the spleen.

Because the white blood cells produced in the bone marrow are involved in the bodys immune defenses, marrow transplants have been used to treat certain types of immune deficiency and hematological disorders, especially leukemia. The sensitivity of marrow to damage by radiation therapy and some anticancer drugs accounts for the tendency of these treatments to impair immunity and blood production.

Examination of the bone marrow is helpful in diagnosing certain diseases, especially those related to blood and blood-forming organs, because it provides information on iron stores and blood production. Bone marrow aspiration, the direct removal of a small amount (about 1 ml) of bone marrow, is accomplished by suction through a hollow needle. The needle is usually inserted into the hip or sternum (breastbone) in adults and into the upper part of the tibia (the larger bone of the lower leg) in children. The necessity for a bone marrow aspiration is ordinarily based on previous blood studies and is particularly useful in providing information on various stages of immature blood cells. Disorders in which bone marrow examination is of special diagnostic value include leukemia, multiple myeloma, Gaucher disease, unusual cases of anemia, and other hematological diseases.

Bone Marrow Transplantation | Bone Marrow Transplant …

By raymumme

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 blood to clot.

A bone marrow transplant is a procedure that replaces a person's faulty bone marrow stem cells. Doctors use these transplants to treat people with certain diseases, such as

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.

In some cases, you can donate your own bone marrow stem cells in advance. The cells are saved and then used later on. Or you can get cells from a donor. The donor might be a family member or unrelated person.

Bone marrow transplantation has serious risks. Some complications can be life-threatening. But for some people, it is the best hope for a cure or a longer life.
