Next Steps for Cardiac Stem Cells – MedStar Heart …

By Sykes24Tracey

To determine why the first stem cell trials were not providing the anticipated therapeutic potential, all variables, such as which stem cells were used, and how they were developed and administered, were open to consideration, says Dr. Epstein.

A key issue was the use of autologous stem cells in all previous studies. Studies demonstrated these old stem cells are functionally defective when compared to stem cells obtained from young healthy individuals. So harvesting a healthy young donors bone marrow and growing the resident stem cells might produce more robust cells.

However, giving a patient allogenic stem cells raised an important issue: whether such cells will be rejected by an immune response. But research showed mesenchymal stem cells (MSCs), a type of adult stem cell, have been designed by nature to be stealth bombers, explainsDr. Epstein. They express molecules on their surface that prevent the body from recognizing the cells as foreign, so the patient does not reject the donated MSCs.

To further explore and refine potential stem cell cardiovascular therapies, MHVI expanded the translational research team to include Michael Lipinski, MD, PhD, an expert in molecular biology and scientific lead for preclinical research at the MedStar Cardiovascular Research Network, and Dror Luger, PhD, an expert in immunology and inflammatory responses. By bringing together these diverse areas of expertise, we forged a team with the potential to produce research that could lead to important breakthroughs in understanding how stem cells might work and thereby provide more successful treatment of patients with cardiac disease, says Dr. Epstein.

CardioCell, a San Diego-based stem cell company focused on stem cell therapy for cardiovascular disease, found that MSCs grew faster and showed improved function when cultured in a reduced oxygen environment. Stem cells typically grow in the body, in bone marrow and other tissues, in a low oxygen environmentonly five percent oxygen, as opposed to room air, which is about 20 percent, explains Dr. Lipinski. All previous stem cell trials used cells exposed to, and grown under, room air oxygen conditions.

Using CardioCells low oxygen-grown MSCs, the MHVI scientists demonstrated biologically important effects occurred, even when the MSCs were administered intravenously. This mode of administration was previously rejected by scientists who thought cells would be trapped in the first capillary bed they traversedthe lungsand never reach the heart.

However, the MHVI team demonstrated a small percentage of these IV administered MSCs did reach the heart, where they could exert beneficial effects. The cells seek out inflamed cardiac tissue after a heart attack because they upregulate receptors that allow them to be attracted to and penetrate inflamed tissue in high numbers, says Dr. Luger.

The investigators also found the cells residing in other tissues could provide other benefits. It has been shown that a heart attack activates the immune and inflammatory systems, including those in the spleen, explains Dr. Luger. The systemic anti-inflammatory effects produced by MSCs in the spleen, lungs and other tissues caused by the molecules secreted by the MSCs could exert positive effects as well. Dr. Epstein added that such anti-inflammatory effects could also benefit the excessive inflammatory activities that exist in many heart failure patients.

For the clinical heart failure trial, MHVI is partnering with CardioCell, which will grow and provide stem cells already used in Phase I and 2a clinical trials and approved by the Food and Drug Administration.

As an extension of their stem cell work, the MHVI investigators are building on the fact that any beneficial effect of adult stem cells will not derive from their transformation into heart muscle, but rather from the molecules they secrete; these, in turn, stimulate pathways favoring tissue healing. The team is investigating the use of liposomes as therapeutic delivery vehicles for these secreted products, which include those with anti-inflammatory and angiogenesis activities.

If successful, using MSCs for anti-inflammatory and immune-modulatory effects could have implicationsfor many different diseases, including arthritis and autoimmune diseases like rheumatoid arthritis. Dr. Epstein cautions that a great deal of research is yet to be done before such applications can be routinely used to treat patients with these conditions. For now, they hope the current studies in heart failure patients will demonstrate effectiveness. If so, Dr. Epstein says, it changes the whole playing field for stem cells.

Spinal Surgery Stem Cell Treatment | ProMedSPINE

By daniellenierenberg

Stem cells have the incredible ability to develop into a variety of different cell types within the body. In addition, stem cells can play a crucial role in internally repairing many types of tissues. During this process, stem cells divide, replenishing other cells without limit.

While stem cells have been used by medical professionals for a wide variety of reasons in order to treat injuries, ailments, and diseases affecting every part of the body, the use of stem cells in the treatment of spinal damage may be the most exciting and potent use yet. Through the application of these spinal treatments, patients have the ability to recover not only more completely, but also in a more natural and therefore more complete manner than ever before. When paired with the insight of a skilled spinal surgeon, the results can be astonishing.

If you or a loved one is suffering from spine damage and are looking to learn more about how stem cell treatments can help you, get in touch with the expert back team at ProMed SPINE today by filling out ouronline contact form. Schedule a consultation with us and begin the path to recovery today!

Stem cells differ from other cell types because they are unspecialized and therefore capable of renewing themselves through cell division. Under certain physiologic or experimental conditions, they have the ability to become tissue or even organ-specific cells with special functions. Given these unique regenerative abilities, stem cells offer new potential in the enhancement of every surgery.

Rather then undergoing an invasive surgery that wont actually repair damage from degenerative disc disease, stem cell spinal treatments are short, minimally invasive and capable of healing the damage that has been done to the disc. Stem cell therapy produces new disc cells inside the disc itself, allowing it to rebuild to a like-new condition. When treating degenerative disc disease, bone marrow is extracted from the patients hipbone and stem cells are filtered out using a centrifuge. Then stem cells are injected into the disc with the help of an x-ray. After this step, the patient is free to go home and begin the recovery process. Over the next few months to a year, patients will experience a lessening of back pain as the disc begins to restore itself. It is quite common for patients who have undergone stem cell injections to experience complete relief from back pain and a vast improvement in their overall quality of life.

Stem cells can also be used to enhance the effects of a spinal fusion surgery. A lack of useful new bone growth after this type of surgery can be a significant problem. This new technology helps patients grow new bone and avoid harvesting a bone graft from the patients own hip or using bone from a deceased donor. By avoiding these steps, patients are able to recover faster and prevent painful procedures.

A major component of stem cells is their ability to reinforce stronger, healthier healing in patients. Oftentimes, the body is in a weakened state following a surgical procedure and therefore more susceptible to developing infection. Stem cells unique ability to replenish themselves offers the body fresh, healthy cells that are not nearly as vulnerable to incurring infection so that the body can heal more quickly and effectively.

After undergoing a surgery and the rehabilitation process that follows, many patients are left with unsightly scars. These scars are often painful reminders of a traumatic event and, in some cases, cause self-consciousness or outright embarrassment due to their appearance. Stem cells have become an increasingly useful aid in ridding patients of unattractive scars so that they can fully recover from their injuries. Stem cells are useful in the treatment of scarring in three major ways: they carry anti-inflammatory properties that prevent excessive scarring, are capable of replenishing normal cells in the tissue through differentiation, and finally, stem cells dissolve the excess collagen in scar tissue by emitting large amounts of enzymes whose specific function is to dissolve scar tissue.

The potential medical benefits of stem cell research are unparalleled in the healing and rejuvenating processes following a spinal procedure. Whether you are facing a major surgery or are considering your options concerning continued pain and physical limitations, knowing what options may be best for you is vital in the search for skilled medical care. Schedule an appointment with a laser spine surgeonto find out how stem cell therapy can be used to help you find a healthier and happier life.

Cure Spinal Cord injury Research, therapies, treatments, 2018

By JoanneRUSSELL25

Update: January 2018

Background information:One of the biggest issues preventing recovery after achronicspinal cord injury is the scar that appears a few days or weeks after the injury and prevents any axon from growing away from the lesion area. One of the key scar reduction strategies involves using the Chondroitinase enzyme.

In this chapter we are also covering the therapeutic strategies that are used to neutralize growth inhibitors (often referred to as NoGo) after the spinal cord injury, and /or promote nerve growth.

The intrathecal delivery of the NoGo Trap protein delivery has shown axonal growth associated with a certain recovery of function by rats. It is reported to promote nerve sprouting and synaptic plasticity, as well as, to a lesser extent, axonal regeneration. The ReNetX company is now planning a clinical trial for cervical injury patients.

Input from Spinal Research, who initiated the project: since 2014, the CHASE-IT consortium has achieved several critical milestones by working on, and overcoming, many of the issues related to creating a safe gene therapy for chondroitinase:

-The gene for chondroitinase can now be expressed in an active form in human cells-Expression of chondroitinase in the spinal cord can now be controlled, switching it on and off using an inducible switch responsive to the antibiotic doxycycline-Treatment gives rise to improved walking and unprecedented upper limb function in clinically-relevant spinal cord injury models

-Demonstrate inducible chondroitinase gene therapy works in chronic injuries-Transfer the inducible gene therapy machinery developed in the lentiviral vector to the more clinically-acceptable Adeno-associated viral (AAV) vector-Eliminate any background expression of chondroitinase when system in the uninduced off state-Confirm chondroitinase-AAV retains comparable efficacy as chondroitinase-L

Stem Cell Basics

By JoanneRUSSELL25

The human body comprises more than 200 types of cells, and every one of these cell types arises from the zygote, the single cell that forms when an egg is fertilized by a sperm. Within a few days, that single cell divides over and over again until it forms a blastocyst, a hollow ball of 150 to 200 cells that give rise to every single cell type a human body needs to survive, including the umbilical cord and the placenta that nourishes the developing fetus.

Each cell type has its own size and structure appropriate for its job. Skin cells, for example, are small and compact, while nerve cells that enable you to wiggle your toes have long, branching nerve fibers called axons that conduct electrical impulses.

Cells with similar functionality form tissues, and tissues organize to form organs. Each cell has its own job within the tissue in which it is found, and all of the cells in a tissue and organ work together to make sure the organ functions properly.

Regardless of their size or structure, all human cells start with these things in common:

Stem cells are the foundation of development in plants, animals and humans. In humans, there are many different types of stem cells that come from different places in the body or are formed at different times in our lives. These include embryonic stem cells that exist only at the earliest stages of development and various types of tissue-specific (or adult) stem cells that appear during fetal development and remain in our bodies throughout life.

Stem cells are defined by two characteristics:

Beyond these two things, though, stem cells differ a great deal in their behaviors and capabilities.

Embryonic stem cells are pluripotent, meaning they can generate all of the bodys cell types but cannot generate support structures like the placenta and umbilical cord.

Other cells are multipotent, meaning they can generate a few different cell types, generally in a specific tissue or organ.

As the body develops and ages, the number and type of stem cells changes. Totipotent cells are no longer present after dividing into the cells that generate the placenta and umbilical cord. Pluripotent cells give rise to the specialized cells that make up the bodys organs and tissues. The stem cells that stay in your body throughout your life are tissue-specific, and there is evidence that these cells change as you age, too your skin stem cells at age 20 wont be exactly the same as your skin stem cells at age 80.

Stem Cells Can Create Skin For Burn Victims | IFLScience

By JoanneRUSSELL25

When burn victims need a skin graft they typically have to grow skin on other parts of their bodies - a process that can take weeks. A new technique uses stem cells derived from the umbilical cord to generate new skin much more quickly. The results were published in Stem Cells Translational Medicine by lead author Ingrid Garzn from the University of Granadas Department of Histology.

Not only can the stem cells develop artificial skin more quickly than regular normal skin growth, but the skin can also be stored so it is ready right when it is needed. Tens of thousands of grafts are performed each year for burn victims, cosmetic surgery patients, and for people with large wounds having difficulty healing. Traditionally, this involves taking a large patch of skin (typically from the thigh) and removing the dermis and epidermis to transplant elsewhere on the body.

The artificial skin requires the use of Wharton's jelly mesenchymal stem cells. As the name implies, Whartons jelly is a gelatinous tissue in the umbilical cord that contains uncommitted mesenchymal stemcells (MSC). The MSC is then combined with agarose(a polysaccharide polymer) and fibrin (the fibrous protein that aids in blood clotting). This yielded two results: skin and the mucosal lining of the mouth. The researchers are very pleased to have found two new uses for the stem cells of Whartons jelly, which have not previously been researched for epithelial applications.

Once the epithelial tissues have been created, researchers can store it in tissue banks. If someone is brought into the hospital following a devastating burn or accident, the tissue is ready to graft immediately; not in a few weeks. However, the stem-cell skin is not able to fully differentiate in vitro. After the graft, it has complete cell-cell junctions and will develop all of the necessary layers of normal epithelial tissue.

The MSCs are taken from the umbilical cord after the baby has been born, which poses no risk to either the mother or the child. This method is relatively inexpensive and has been shown to be more efficient than stem cells derived from bone marrow.

Spinal Cord Injury and Stem Cells | Cells4Life

By Dr. Matthew Watson

The spinal cord is a collection of nerve fibres and other tissues contained with the spine. The nerves within the spinal cord connect the peripheral nervous system to the brain forming the central nervous system. The spinal cord is essential for the transmission and reception of electrical messages to and from the brain to other areas of the body. Should the spinal cord become damaged, the impacts can be devastating or even fatal.

Preventable causes such as violence, falls and road traffic accents account for the majority of spinal cord injuries. Every year, between 250,000 and 500,000 people suffer a spinal cord injury globally. Unfortunately, those with a spinal cord injury are 2 to 5 times more likely to suffer premature death than those without.[1]

A spinal cord injury can affect anyone at any time and unfortunately there is currently no effective treatment available to those with a spinal cord injury.

The cost of spinal cord injury to the UK alone is estimated at 1 billion per annum.[2]

While there is currently no effective treatment for spinal cord injury available to the general public, stem cells could hold the key to successful spinal cord repair in the future. A British professor, Geoffrey Raisman, headed research which used stem cells to enable a paralysed man to walk again.

The research used a type of stem cell called olfactory ensheathing cells (OECs) from the nose of the patient and transplanted them into the spinal cord. OECs are specialist cells which form part of the sense of smell enabling nerve fibres in the olfactory system to continually renew. It was previously thought that severed nerve fibres in the spinal cord were unable to repair themselves. However, once OECs have been transplanted into the spinal cord it appears they facilitate the growth of the ends of severed nerve fibres and even enable them join together.[6]

In addition to Raismans research, Dr. Carlos Lima of Portugal had transplanted olfactory stem cells to treat spinal cord injury in over 100 patients. Lima and his team showed that a few patients were able to regain some motor function and sensation thanks to the transplanted olfactory stem cells.[7]

Promisingly, there are currently 38 clinical trials investigating the application of stem cells in spinal cord injury.[8]

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.

COPD

Over 32 million Americans suffer from chronic obstructive pulmonary disease (also known as COPD). COPD is a progressive lung disease, however regenerative medicine, such as lung regeneration therapies using stem cells are showing potential for COPD by encouraging tissue repair and reducing inflammation to the diseased lung tissue.

Following up with stem cell therapy and exome therapy immediately in the first 36 to 48 hours after stroke symptoms surface has proven to be crucial to long-term recovery and regaining mobility again. Cell therapy also calms post-stroke inflammation in the body, and reduces risk of serious infections.

Parkinsons is a neurodegenerative brain disorder caused by the gradual loss of dopamine-producing cells in the brain. It afflicts more than 1 million people in the U.S., and currently, there is no known cure. Stem cell therapies have been showing incredible progress. Using induced pluripotent stem (iPS) cells, a mature cell can be reprogrammed into an embryonic-like, healthy and highly-functioning state, which has the potential to become a dopamine-producing cell in the brain.

A thick, full head of hair is possible, naturally! Stem cell and exosome therapy promotes healing from within to naturally stimulate hair follicles, which encourages new hair growth. Using your own stem cells, Platelet Rich Plasma (PRP) and exosomes, you can regrow your own healthy, thick hair naturally and restore your confidence!

Erectile Dysfunction (ED) is the inability to achieve or maintain an erection sufficient for satisfactory sexual intercourse. Regenerative medicine offers a non-surgical option that commonly uses the patients own stem cells, exosomes, and other sources of growth factors to regenerate healthy tissue to improve performance and sensation.

If chronic joint pain is derailing your active lifestyle, then youre not alone. Regenerative medicine offers a non-surgical option that commonly uses the patients own stem cells, exosomes, and other sources of growth factors to reduce inflammation, promote natural healing and regenerate healthy tissue surrounding the joint for relief.

Multiple Sclerosis (MS) affects 400,000 people in the U.S., and occurs when the body has an abnormal immune system response and attacks the central nervous system. Regenerative medicine now offers treatment for MS with stem cell therapy, which is an exciting and rapidly developing field of therapy. Stem cells work to repair damaged cells these new cells can become replacement cells to restore normal functionality.

Spinal cord injuries are as complex as they are devastating. Today, cellular treatments, usually a combination of therapies, such as stem cell, Platelet Rich Plasma (PRP) and exosome therapy with growth factors are showing promise in contributing to spinal cord repair and reducing inflammation at the site of injury.

If you have chronic nerve injury pain that doesnt fade, your health care provider may recommend surgery to reverse the damage. However, regenerative medicine offers a non-surgical option to repair damaged tissue and reduce inflammation at the site of injury. Stem cell therapy commonly uses the patients own stem cells, exosomes, and other sources of growth factors to regenerate healthy tissue.

Neuropathy also called peripheral neuropathy occurs when nerves are damaged and cant send messages from the brain and spinal cord to the muscles, skin and other parts of the body. Simply put, the two areas stop communicating. Stem cell and exosome therapies treat damaged nerves affected by neuropathy, and they have the ability to replicate and create new, healthy cells, while repairing damaged tissue.

Stem Cell Treatments – Brain and Spinal Cord

By Sykes24Tracey

Because stem cells have the potential to generate cells designed to replace or repair cells damaged by spinal cord injury, advocates of stem cell research and treatment believe that the benefits far outweigh the negative aspects. Opponents of this research and treatment, however, typically bring up the issue of embryonic stem cells, which are harvested from embryos and fetal tissue. Accordingly, they feel the use of these embryonic stem cells is not moral or ethical. Because stem cells are harvested from embryos and fetal tissue, they feel it is not moral or ethical. Secondly, opponents are concerned about the health and safety of the participants in human stem cell research trials. It is important to note that non-embryonic stem cells, called somatic or adult stem cells, have recently been identified in various body tissues including brain, bone marrow, blood vessels, and various organ tissues.

Lets talk about how stem cell research could possibly impact spinal cord injury. Stem cell research came on the scene in 1998, when a group of scientists isolated pluripotent stem cells from human embryos and grew them in a culture. Since then, specialists have discovered that stem cells can become any of the 200 specialized cells in the body, giving them the ability to repair or replace damaged cells and tissues. While not yet known to have the diversification potential of embryonic stem cells, adult somatic cells act similarly and are generating excitement in the research and medical community.

When all is said and done, could stem cell treatment be the miracle cure for spinal cord injury and paralysis? Well, we dont really know. Because of all of the controversy, much of the evidence that shows stem cells can be turned into specific cells for transplantation involves only mice, whose cells are significantly different than human cells. Nevertheless, some initial research points to promising results. One hurdle that remains to be cleared is whether an immune response would reject a cellular transplant.

Ultimately, no one yet knows the extent to which stem cell treatment could help spinal cord injury and paralysis. Scientists remain hopeful, but currently there just hasnt been enough research done to substantiate any particular result. Additional research needs to be done before we have more definitive answers.

Again, we just dont know. Much of the answer depends upon whether the political process and moral debate continues to limitand put the hold onthe amount of research done. At this point its impossible to say for sure whenor even ifstem cells will be useful in the treatment of paralysis.

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?

Syrinx of the Spinal Cord or Brain Stem – Neurologic Disorders – Merck Manuals …

By raymumme

A syrinx is a fluid-filled cavity within the spinal cord (syringomyelia) or brain stem (syringobulbia). Predisposing factors include craniocervical junction abnormalities, previous spinal cord trauma, and spinal cord tumors. Symptoms include flaccid weakness of the hands and arms and deficits in pain and temperature sensation in a capelike distribution over the back and neck; light touch and position and vibration sensation are not affected. Diagnosis is by MRI. Treatment includes correction of the cause and surgical procedures to drain the syrinx or otherwise open CSF flow.

Syrinxes usually result from lesions that partially obstruct CSF flow. At least half of syrinxes occur in patients with congenital abnormalities of the craniocervical junction (eg, herniation of cerebellar tissue into the spinal canal, called Chiari malformation), brain (eg, encephalocele), or spinal cord (eg, myelomeningocele). For unknown reasons, these congenital abnormalities often expand during the teen or young adult years. A syrinx can also develop in patients who have a spinal cord tumor, scarring due to previous spinal trauma, or no known predisposing factors. About 30% of people with a spinal cord tumor eventually develop a syrinx.

Syringomyelia is a paramedian, usually irregular, longitudinal cavity. It commonly begins in the cervical area but may extend downward along the entire length of the spinal cord.

Syringobulbia, which is rare, usually occurs as a slitlike gap within the lower brain stem and may disrupt or compress the lower cranial nerve nuclei or ascending sensory or descending motor pathways.

Spinal Chord Injury Stem Cell Therapy | NSI Stem Cell

By LizaAVILA

How Adipose Stem Cell Technology Develops Spinal Cord Injury Treatment

No matter where they may naturally be found in the body, Adult Stem Cells are like electricity. They are pure potential. When properly stimulated, stem cells become whatever type of cell the body needs: bone, blood, cartilage, muscle, nerve, and more. The results of studies like those published on CellTherapyJournal.org and reported on at MedScape.com state that stem cells, particularly Adipose-Derived Stem Cells, have great potential in the development of Stem Cell Therapy for Spinal Cord Injury.*

When a Spinal Cord Injury occurs, the resulting inflammation releases inhibiting factors that ultimately cause the fibers of nerve cells to retract. Scar tissue develops, effectively preventing a bridge to be formed across the area of injury. This, in essence, is what prevents healing and causes the debilitating effects after injury. But research has shown that Adult Stem Cells, particularly Adipose-Derived Stem Cells, have the potential for bridging the gap. Additionally, stem cells might excrete substances that reduce damaging inflammation. Already, trials involving Spinal Cord Injury Therapy via stem cells are producing remarkable effects.

Studies from around the world are reporting exciting results, from trial subjects undergoing stem cell therapy for spinal cord injury who regain the capacity to feel light touch to some who were able to walk for at least an hour with the aid of a walker. An improvement in bladder and bowel control was also reported.

Where To Find Stem Cell Therapy In The U.S.

No medical clinic is better equipped and keeps a closer eye on the very latest Stem Cell Treatments than NSI Stem Cell Center in Florida. Rest assured that we are poised and ready to offer stem cell Spinal Cord Injury Therapy at its earliest development. We are already providing therapies for neurological disorders such as Multiple Sclerosis and Parkinsons Disease, as well as many treatments for a growing list of other injuries, illnesses, and chronic conditions.

Printing Skin Cells on Burn Wounds – Wake Forest School of …

By daniellenierenberg

Skin is the body's largest organ. Loss of the skin barrierresults in fluid and heat loss and the risk of infection. Thetraditional treatment for deep burns is to cover them with healthyskin harvested from another part of the body. But in cases ofextensive burns, there often isn't enough healthy skin toharvest.

During phase I of AFIRM, WFIRM scientists designed, built andtested a printer designed to print skin cells onto burn wounds. The"ink" is actually different kinds of skin cells. A scanner is usedto determine wound size and depth. Different kinds of skin cellsare found at different depths. This data guides the printer as itapplies layers of the correct type of cells to cover the wound. Youonly need a patch of skin one-tenth the size of the burn to growenough skin cells for skin printing.

During Phase II of AFIRM, the WFIRM team will explore whether atype of stem cell found in amniotic fluid and placenta (afterbirth)is effective at healing wounds. The goal of the project is to bringthe technology to soldiers who need it within the next 5 years.

This video -- with a mock hand and burn -- demonstrates the process.

Studies: Stem cells reverse heart damage – CNN

By LizaAVILA

Story highlights

On a June day in 2009, a 39-year-old man named Ken Milles lay on an exam table at Cedars-Sinai Medical Center in Los Angeles. A month earlier, he'd suffered a massive heart attack that destroyed nearly a third of his heart.

"The most difficult part was the uncertainty," he recalls. "Your heart is 30% damaged, and they tell you this could affect you the rest of your life." He was about to receive an infusion of stem cells, grown from cells taken from his own heart a few weeks earlier. No one had ever tried this before.

About three weeks later, in Kentucky, a patient named Mike Jones underwent a similar procedure at the University of Louisville's Jewish Hospital. Jones suffered from advanced heart failure, the result of a heart attack years earlier. Like Milles, he received an infusion of stem cells, grown from his own heart tissue.

"Once you reach this stage of heart disease, you don't get better," says Dr. Robert Bolli, who oversaw Jones' procedure, explaining what doctors have always believed and taught. "You can go down slowly, or go down quickly, but you're going to go down."

Conventional wisdom took a hit Monday, as Bolli's group and a team from Cedars-Sinai each reported that stem cell therapies were able to reverse heart damage, without dangerous side effects, at least in a small group of patients.

In Bolli's study, published in The Lancet, 16 patients with severe heart failure received a purified batch of cardiac stem cells. Within a year, their heart function markedly improved. The heart's pumping ability can be quantified through the "Left Ventricle Ejection Fraction," a measure of how much blood the heart pumps with each contraction. A patient with an LVEF of less than 40% is considered to suffer severe heart failure. When the study began, Bolli's patients had an average LVEF of 30.3%. Four months after receiving stem cells, it was 38.5%. Among seven patients who were followed for a full year, it improved to an astounding 42.5%. A control group of seven patients, given nothing but standard maintenance medications, showed no improvement at all.

"We were surprised by the magnitude of improvement," says Bolli, who says traditional therapies, such as placing a stent to physically widen the patient's artery, typically make a smaller difference. Prior to treatment, Mike Jones couldn't walk to the restroom without stopping for breath, says Bolli. "Now he can drive a tractor on his farm, even play basketball with his grandchildren. His life was transformed."

At Cedars-Sinai, 17 patients, including Milles, were given stem cells approximately six weeks after suffering a moderate to major heart attack. All had lost enough tissue to put them "at big risk" of future heart failure, according to Dr. Eduardo Marban, the director of the Cedars-Sinai Heart Institute, who developed the stem cell procedure used there.

The results were striking. Not only did scar tissue retreat -- shrinking 40% in Ken Milles, and between 30% and 47% in other test subjects -- but the patients actually generated new heart tissue. On average, the stem cell recipients grew the equivalent of 600 million new heart cells, according to Marban, who used MRI imaging to measure changes. By way of perspective, a major heart attack might kill off a billion cells.

"This is unprecedented, the first time anyone has grown living heart muscle," says Marban. "No one else has demonstrated that. It's very gratifying, especially when the conventional teaching has been that the damage is irreversible."

Perhaps even more important, no treated patient in either study suffered a significant health setback.

The twin findings are a boost to the notion that the heart contains the seeds of its own rebirth. For years, doctors believed that heart cells, once destroyed, were gone forever. But in a series of experiments, researchers including Bolli's collaborator, Dr. Piero Anversa, found that the heart contains a type of stem cell that can develop into either heart muscle or blood vessel components -- in essence, whatever the heart requires at a particular point in time. The problem for patients like Mike Jones or Ken Milles is that there simply aren't enough of these repair cells waiting around. The experimental treatments involve removing stem cells through a biopsy, and making millions of copies in a laboratory.

The Bolli/Anversa group and Marban's team both used cardiac stem cells, but Bolli and Anversa "purified" the CSCs, so that more than 90% of the infusion was actual stem cells. Marban, on the other hand, used a mixture of stem cells and other types of cells extracted from the patient's heart. "We've found that the mixture is more potent than any subtype we've been able to isolate," he says. He says the additional cells may help by providing a supportive environment for the stem cells to multiply.

Other scientists, including Dr. Douglas Losordo, have produced improvements in cardiac patients using stem cells derived from bone marrow. "The body contains cells that seem to be pre-programmed for repair," explains Losordo. "The consistent thing about all these approaches is that they're leveraging what seems to be the body's own repair mechanism."

Losordo praised the Lancet paper, and recalls the skepticism that met Anversa's initial claims, a decade ago, that there were stem cells in the adult heart. "Some scientists are always resistant to that type of novelty. You know the saying: First they ignore you, then they attack you and finally they imitate you."

Denis Buxton, who oversees stem cell research at the National Heart, Lung and Blood Institute at the National Institutes of Health, calls the new studies "a paradigm shift, harnessing the heart's own regenerative processes." But he says he would like to see more head-to-head comparisons to determine which type of cells are most beneficial.

Questions also remain about timing. Patients who suffer large heart attacks are prone to future damage, in part because the weakened heart tries to compensate by dilating -- swelling -- and by changing shape. In a vicious circle, the changes make the heart a less efficient pump, which leads to more overcompensation, and so on, until the end result is heart failure. Marban's study aimed to treat patients before they could develop heart failure in the first place.

In a third study released Monday, researchers treated patients with severe heart failure with stem cells derived from bone marrow. In a group of 60 patients, those receiving the treatment had fewer heart problems over the course of a year, as well as improved heart function.

A fourth study also used cells derived from bone marrow, but injected them into patients two to three weeks after a heart attack. Previous studies, with the cells given just days afterward, found a modest improvement in heart function. But Monday, the lead researcher, Dr. Dan Simon of UH Case Medical Center, reported that with the three-week delay, patients did not see the same benefit.

With other methods, there may be a larger window of opportunity. At least in initial studies, Losordo's bone marrow treatments helped some patients with long-standing heart problems. Bolli's Lancet paper suggests that CSCs, too, might help patients with advanced disease. "These patients had had heart failure for several years. They were a wreck!" says Bolli. "But we found their stem cells were still very competent." By that, he means the cells were still capable of multiplying and of turning into useful muscle and blood vessel walls.

Marban has an open mind on the timing issue. In fact, one patient from his control group e-mailed after the study was complete, saying he felt terrible and pleading for an infusion of stem cells. At Marban's request, the FDA granted special approval to treat him. "He had a very nice response. That was 14 months after his heart attack. Of course that's just one person, and we need bigger studies," says Marban.

For Ken Milles, the procedure itself wasn't painful, but it was unsettling. The biopsy to harvest the stem cells felt "weird," he recalls, as he felt the doctor poking around inside his heart. The infusion, a few weeks later, was harder. The procedure -- basically the same as an angioplasty -- involved stopping blood flow through the damaged artery for three minutes, while the stem cells were infused. "It felt exacfly like I was having a heart attack again," Milles remembers.

Milles had spent the first weeks after his heart attack just lying in bed re-watching his "Sopranos" DVDs, but within a week of the stem cell infusion, he says, "I was reinvigorated." Today he's back at work full time, as an accounting manager at a construction company. He's cut out fast food and shed 50 pounds. His wife and two teenage sons are thrilled.

Denis Buxton says the new papers could prove a milestone. "We don't have anything else to actually regenerate the heart. These stem cell therapies have the possibility of actually reversing damage."

Bolli says he'll have to temper his enthusiasm until he can duplicate the results in larger studies, definitive enough to get stem cell therapy approved as a standard treatment. "If a phase 3 study confirmed this, it would be the biggest advance in cardiology in my lifetime. We would possibly be curing heart failure. It would be a revolution."

Stem Cells & Spinal Cord Injuries – sci-info-pages.com

Stem cell therapy can be defined as a part of a group of new techniques, or technologies that rely on replacing diseased or dysfunctional cells with healthy, functioning ones. These new techniques are being applied experimentally to a wide range of human disorders, including many types of cancer, neurological diseases such as Parkinson's disease and ALS (Lou Gehrig's disease), spinal cord injuries, and diabetes.

Coalition for the Advancement of Medical ResearchThe Coalition for the Advancement of Medical Research (CAMR) is comprised of nationally-recognized patient organizations, universities, scientific societies, foundations, and individuals with life-threatening illnesses and disorders, advocating for the advancement of breakthrough research and technologies in regenerative medicine - including stem cell research and somatic cell nuclear transfer - in order to cure disease and alleviate suffering.

Portraits of HopeVolunteer group of patients and their families and friends who believe that stem cell research has the potential to save the lives of those afflicted by many medical conditions, including spinal cord injury. Purpose is to show the faces and recount the stories of people who have such illnesses and present these portraits to federal and state legislators in request for government support.

Induced Pluripotent Stem Cells for Cardiovascular …

By LizaAVILA

Nearly 500,000 people in the US die of sudden cardiac death each year, and long QT syndrome (LQTS) is a major form of sudden cardiac death. LQTS can be triggered by drug exposure or stresses. Drug-induced LQTS is the single most common reason for drugs to be withdrawn from clinical trials, causing major setbacks to drug discovery efforts and exposing people to dangerous drugs. In most cases, the mechanism of drug-induced LQTS is unknown. However, there are genetic forms of LQTS that should allow us to make iPS cellderived heart cells that have the key features of LQTS. Our objective is to produce a cell-based test for LQTS with induced pluripotent stem (iPS) cell technology, which allows adult cells to be reprogrammed to be stem celllike cells.Despite the critical need, current tests for drug-induced LQTS are far from perfect. As a result, potentially unsafe drugs enter clinical trials, endangering people and wasting millions of dollars in research funds. When drugs that cause LQTS, such as terfenadine (Seldane), enter the market, millions of people are put at serious risk. Unfortunately, it is very difficult to know when a drug will cause LQTS, since most people who develop LQTS have no known genetic risk factors. The standard tests for LQTS use animal models or hamster cells that express human heart genes at high levels. Unfortunately, cardiac physiology in animal models (rabbits and dogs) differs from that in humans, and hamster cells lack many key features of human heart cells. Human embryonic stem cells (hESCs) can be differentiated into heart cells, but we do not know the culture conditions that would make the assay most similar to LQTS in a living person. These problems could be solved if we had a method to grow human heart cells from people with genetic LQTS mutations, so that we know the exact test conditions that would reflect the human disease. This test would be much more accurate than currently available tests and would help enable the development of safer human pharmaceuticals.Our long-term goal is to develop a panel of iPS cell lines that better represent the genetic diversity of the human population. Susceptibility to LQTS varies, and most people who have life-threatening LQTS have no known genetic risk factors. We will characterize iPS cells with well-defined mutations that have clinically proven responses to drugs that cause LQTS. These iPS cell lines will be used to refine testing conditions. To validate the iPS cellbased test, the results will be directly compared to the responses in people. These studies will provide the foundation for an expanded panel of iPS cell lines from people with other genetic mutations and from people who have no genetically defined risk factor but still have potentially fatal drug-induced LQTS. This growing panel of iPS cell lines should allow for testing drugs for LQTS more effectively and accurately than any current test.To meet these goals, we made a series of iPS cells that harbor different LQTS mutations. These iPS cells differentiate into beating cardiomyocytes. We are now evaluating these LQTS cell lines in cellular assays. We are hopeful that our studies will meet or exceed all the aims of our original proposal.
