Amniotic stem cells demonstrate healing potential
By raymumme
Rice University and Texas Children's Hospital scientists are using stem cells from amniotic fluid to promote the growth of robust, functional blood vessels in healing hydrogels.
In new experiments, the lab of bioengineer Jeffrey Jacot combined versatile amniotic stem cells with injectable hydrogels used as scaffolds in regenerative medicine and proved they enhance the development of vessels needed to bring blood to new tissue and carry waste products away.
The results appear in the Journal of Biomedical Materials Research Part A.
Jacot and his colleagues study the use of amniotic fluid cells from pregnant women to help heal infants born with congenital heart defects. Such fluids, drawn during standard tests, are generally discarded but show promise for implants made from a baby's own genetically matched material.
He contends amniotic stem cells are valuable for their ability to differentiate into many other types of cells, including endothelial cells that form blood vessels.
"The main thing we've figured out is how to get a vascularized device: laboratory-grown tissue that is made entirely from amniotic fluid cells," Jacot said. "We showed it's possible to use only cells derived from amniotic fluid."
In the lab, researchers from Rice, Texas Children's Hospital and Baylor College of Medicine combined amniotic fluid stem cells with a hydrogel made from polyethylene glycol and fibrin. Fibrin is a biopolymer critical to blood clotting, cellular-matrix interactions, wound healing and angiogenesis, the process by which new vessels branch off from existing ones. Fibrin is widely used as a bioscaffold but suffers from low mechanical stiffness and rapid degradation. Combining fibrin and polyethylene glycol made the hydrogel much more robust, Jacot said.
The lab used vascular endothelial growth factor to prompt stem cells to turn into endothelial cells, while the presence of fibrin encouraged the infiltration of native vasculature from neighboring tissue.
Mice injected with fibrin-only hydrogels showed the development of thin fibril structures, while those infused with the amniotic cell/fibrin hydrogel showed far more robust vasculature, according to the researchers.
Similar experiments using hydrogel seeded with bone marrow-derived mesenchymal cells also showed vascular growth, but without the guarantee of a tissue match, Jacot said. Seeding with endothelial cells didn't work as well as the researchers expected, he said.

Amniotic stem cells demonstrate healing potential
Stem cell disease model clarifies bone cancer trigger
By JoanneRUSSELL25
Using induced pluripotent stem cells (iPSCs), a team led by Mount Sinai researchers has gained new insight into genetic changes that may turn a well known anti-cancer signaling gene into a driver of risk for bone cancers, where the survival rate has not improved in 40 years despite treatment advances.
The study results, published today in the journal Cell, revolve around iPSCs, which since their 2006 discovery have enabled researchers to coax mature (fully differentiated) bodily cells (e.g. skin cells) to become like embryonic stem cells. Such cells are pluripotent, able to become many cell types as they multiply and differentiate to form tissues. The iPSCs can then be converted again as needed into differentiated cells such as heart muscle, nerve cells, bone, etc.
While some seek to use iPSCs as replacements for cells compromised by disease, the new Mount Sinai study sought to determine if they could serve as an accurate model of genetic disease "in a dish." In this context, the dish stands for a self-renewing, unlimited supply of iPSCs or a cell line - which enables in-depth study of disease versions driven by each person's genetic differences. When matched with patient records, iPSCs and iPSC-derived target cells may be able to predict a patient's prognosis and whether or not a given drug will be effective for him or her.
In the current study, skin cells from patient with and without disease were turned into patient-specific iPSC lines, and then differentiated into bone-making cells where both rare and common bone cancers start. This new bone cancer model does a better job than previously used mouse or cellular models of "recapitulating" the features of bone cancer cells driven by key genetic changes.
"Our study is among the first to use induced pluripotent stem cells as the foundation of a model for cancer," said lead author Dung-Fang Lee, PhD, a postdoctoral fellow in the Department of Developmental and Regenerative Biology, Icahn School of Medicine at Mount Sinai. "This model, when combined with a rare genetic disease, revealed for the first time how a protein known to prevent tumor growth in most cases, p53, may instead drive bone cancer when genetic changes cause too much of it to be made in the wrong place."
Rare Disease Sheds Light on Common Disease
The Mount Sinai disease model research is based on the fact that human genes, the DNA chains that encode instructions for building the body's structures and signals, randomly change all the time. As part of evolution, some code changes, or mutations, make no difference, some confer advantages, and others cause disease. Beyond inherited mutations that contribute to cancer risk, the wrong mix of random, accumulated DNA changes in bodily (somatic) cells as we age also contributes to cancer risk.
The current study focused on the genetic pathways that cause a rare genetic disease called Li-Fraumeni Syndrome or LFS, which comes with high risk for many cancers in affected families. A common LFS cancer type is osteosarcoma (bone cancer), with many diagnosed before the age of 30. Beyond LFS, osteosarcoma is the most common type of bone cancer in all children, and after leukemia, the second leading cause of cancer death for them.
Importantly, about 70 percent of LFS families have a mutation in their version of the gene TP53, which is the blueprint for protein p53, well known by the nickname "the tumor suppressor." Common forms of osteosarcoma, driven by somatic versus inherited mutations, have also been closely linked by past studies to p53 when mutations interfere with its function.
Rare genetic diseases like LFS are good study models because they tend to proceed from a change in a single gene, as opposed to many, overlapping changes seen in more related common diseases, in this case more common, non-inherited bone cancers. The LFS-iPSC based modeling highlights the contribution of p53 alone to osteosarcoma.

Fecal transplant, stem cells may help Crohn's disease
By Sykes24Tracey
Two experimental therapies might help manage the inflammatory bowel disorder Crohn's disease, if this early research pans out.
In one study, researchers found that a fecal transplant -- stool samples taken from a healthy donor -- seemed to send Crohn's symptoms into remission in seven of nine children treated.
In another, a separate research team showed that stem cells can have lasting benefits for a serious Crohn's complication called fistula.
According to the Crohn's & Colitis Foundation, up to 700,000 Americans have Crohn's -- a chronic inflammatory disease that causes abdominal cramps, diarrhea, constipation and rectal bleeding. It arises when the immune system mistakenly attacks the lining of the digestive tract.

A number of drugs are available to treat Crohn's, including drugs called biologics, which block certain immune-system proteins.
But fecal transplants take a different approach, explained Dr. David Suskind, a gastroenterologist at Seattle Children's Hospital who led the new study.
Instead of suppressing the immune system, he said, the transplants alter the environment that the immune system is reacting against: the "microbiome," which refers to the trillions of bacteria that dwell in the gut.
Like the name implies, a fecal transplant involves transferring stool from a donor into a Crohn's patient's digestive tract. The idea is to change the bacterial composition of the gut, and hopefully quiet the inflammation that causes symptoms.

Spinal cord injury – Wikipedia, the free encyclopedia
By NEVAGiles23
A spinal cord injury (SCI) is an injury to the spinal cord resulting in a change, either temporary or permanent, in the cord's normal motor, sensory, or autonomic function.[1] Common causes of damage are trauma (car accident, gunshot, falls, sports injuries, etc.) or disease (transverse myelitis, polio, spina bifida, Friedreich's ataxia, etc.). The spinal cord does not have to be severed in order for a loss of function to occur. Depending on where the spinal cord and nerve roots are damaged, the symptoms can vary widely, from pain to paralysis to incontinence.[2][3] Spinal cord injuries are described at various levels of "incomplete", which can vary from having no effect on the patient to a "complete" injury which means a total loss of function.
Treatment of spinal cord injuries starts with restraining the spine and controlling inflammation to prevent further damage. The actual treatment can vary widely depending on the location and extent of the injury. In many cases, spinal cord injuries require substantial physical therapy and rehabilitation, especially if the patient's injury interferes with activities of daily life.
Research into treatments for spinal cord injuries includes controlled hypothermia and stem cells, though many treatments have not been studied thoroughly and very little new research has been implemented in standard care.
The American Spinal Injury Association (ASIA) first published an international classification of spinal cord injury in 1982, called the International Standards for Neurological and Functional Classification of Spinal Cord Injury. Now in its sixth edition, the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) is still widely used to document sensory and motor impairments following SCI.[4] It is based on neurological responses, touch and pinprick sensations tested in each dermatome, and strength of the muscles that control ten key motions on both sides of the body, including hip flexion (L2), shoulder shrug (C4), elbow flexion (C5), wrist extension (C6), and elbow extension (C7).[5] Traumatic spinal cord injury is classified into five categories on the ASIA Impairment Scale:
Dimitrijevic[6] proposed a further class, the so-called discomplete lesion, which is clinically complete but is accompanied by neurophysiological evidence of residual brain influence on spinal cord function below the lesion.[7]
Signs recorded by a clinician and symptoms experienced by a patient will vary depending on where the spine is injured and the extent of the injury. These are all determined by the area of the body that the injured area of the spine innervates. A section of skin innervated through a specific part of the spine is called a dermatome, and spinal injury can cause pain, numbness, or a loss of sensation in the relevant areas. A group of muscles innervated through a specific part of the spine is called a myotome, and injury to the spine can cause problems with voluntary motor control. The muscles may contract uncontrollably, become weak, or be completely paralysed. The loss of muscle function can have additional effects if the muscle is not used, including atrophy of the muscle and bone degeneration.
A severe injury may also cause problems in parts of the spine below the injured area. In a "complete" spinal injury, all functions below the injured area are lost. An "incomplete" spinal cord injury involves preservation of motor or sensory function below the level of injury in the spinal cord.[8] If the patient has the ability to contract the anal sphincter voluntarily or to feel a pinprick or touch around the anus, the injury is considered to be incomplete. The nerves in this area are connected to the very lowest region of the spine, the sacral region, and retaining sensation and function in these parts of the body indicates that the spinal cord is only partially damaged. This includes a phenomenon known as sacral sparing which involves the preservation of cutaneous sensation in the sacral dermatomes, even though sensation is impaired in the thoracic and lumbar dermatomes below the level of the lesion.[9] Sacral sparing may also include the preservation of motor function (voluntary external anal sphincter contraction) in the lowest sacral segments.[8] Sacral sparing has been attributed to the fact that the sacral spinal pathways are not as likely as the other spinal pathways to become compressed after injury.[9] The sparing of the sacral spinal pathways can be attributed to the lamination of fibers within the spinal cord.[9]
A complete injury frequently means that the patient has little hope of functional recovery.[citation needed] The relative incidence of incomplete injuries compared to complete spinal cord injury has improved over the past half century, due mainly to the emphasis on better initial care and stabilization of spinal cord injury patients.[10] Most patients with incomplete injuries recover at least some function.[citation needed]
Determining the exact "level" of injury is critical in making accurate predictions about the specific parts of the body that may be affected by paralysis and loss of function. The level is assigned according to the location of the injury by the vertebra of the spinal column closest to the injury on the spinal cord.
Cervical (neck) injuries usually result in full or partial tetraplegia (Quadriplegia). However, depending on the specific location and severity of trauma, limited function may be retained.

Human 'heart on a chip' to aid drug tests
By Dr. Matthew Watson
for the first time, scientists - including an Indian American bioengineer - have developed a network of pulsating cardiac muscle cells housed in an inch-long silicone device that effectively models human heart tissue.
This organ-on-a-chip represents a major step forward in the development of accurate, faster methods of testing for drug toxicity.
"Ultimately, these chips could replace the use of animals to screen drugs for safety and efficacy," said professor Kevin Healy of University of California, Berkeley, who led the team.
"This system is not a simple cell culture where tissue is being bathed in a static bath of liquid," said study lead author Anurag Mathur, a postdoctoral scholar in Healy's lab.
"We designed this system so that it is dynamic. It replicates how tissue in our bodies actually gets exposed to nutrients and drugs," Mathur explained.
The study authors noted a high failure rate associated with the use of nonhuman animal models to predict human reactions to new drugs.
Much of the failure is due to fundamental differences in biology between species, the researchers explained.
"Using a well-designed model of a human organ could significantly cut the cost and time of bringing a new drug to market," Healy added.
The heart cells were derived from human-induced pluripotent stem cells, the adult stem cells that can be coaxed to become many different types of tissue.
The researchers designed their cardiac microphysiological system, or heart-on-a-chip, so that its 3D structure would be comparable to the geometry and spacing of connective tissue fibre in a human heart.

Bone marrow or peripheral blood stem cell transplant for …
By Sykes24Tracey
Normal doses of chemotherapy (chemo) can harm normal cells as well as cancer cells. A stem cell transplant offers doctors a way to use the very high doses of chemo needed to kill all the leukemia cells. Although the drugs destroy the patient's bone marrow, stem cells given after the chemo can restore the blood-making bone marrow stem cells. This is called a stem cell transplant (SCT).
These blood-forming stem cells can come from the bone marrow or peripheral blood from either the patient or from a donor whose tissue type closely matches that of the patient. For CML, a donor (or allogeneic) transplant is most often used. The donor may be a brother or sister or less often a person not related to the patient.
Before modern targeted therapy drugs like imatinib (Gleevec), SCT was commonly used to treat CML. Thats because before drugs like imatinib, less than half of patients lived more than 5 years after diagnosis. Now, these drugs are the standard treatment, and transplants are being used less often. Still, a SCT from a donor offers the only proven chance to cure this disease, and many doctors will recommend a transplant for younger patients, especially children. Transplant may also be recommended if the CML is not responding well to the new drugs.

A bone marrow transplant made them blood brothers
By daniellenierenberg
With no match in the family, his doctors in Ahmedabad started scrounging for random donors across India. There are only four voluntary marrow donor registries in Delhi, Chennai and Mumbai.
Two years ago, 15-year-old blood cancer patient Bhargav Gajipara's parents were a worried lot. Doctors had given up all hope for his cure as no medicines would work on the cancer. The last resort, they said, was a bone marrow transplant. Bhargav was suffering from acute myeloid leukemia (AML), a condition in which cancerous white blood cells (WBCs) get generated in the bone marrow and circulate in the blood stream. Even as Bhargav had fever and bleeding, his search for a bone marrow match within his family failed. The chances of a bone marrow transplant for him looked bleak until May in 2013.
With no match in the family, his doctors in Ahmedabad started scrounging for random donors across India. There are only four voluntary marrow donor registries in Delhi, Chennai and Mumbai.
Life suddenly changed for Bhargav in July, when his bone marrow matched with hundred percent accuracy with that of 26-year-old media professional Sachin Mampatta of Mumbai. The chance of finding a random bone marrow donor match are one in over 10,000.
On Tuesday, Bhargav and Sachin met one year after the latter donated his marrow to the patient. Sachin had incidentally pledged his marrow around the same time when the request for procuring Bhargav's match was put in by doctors. "I became aware that people can pledge their marrow when I attended a marrow donor drive at Matunga. The doctors took a swab from my inner cheek and genetically typed it. A few months later I received a call asking if I would be in a position to donate my marrow to Bhargav. I readily agreed," said Sachin.
"Sachin's blood was taken and his stem cells were extracted from the bloodstream. The 220 ml of stem cell component was transported to the Ahmedabad-based hospital where Bhargava was admitted," said Raghu Rajagopal, CEO, Datri Blood Stem Cell Donors Registry.
The doctors administered injections to destroy all the WBCs in Bhargav's blood and transfused Sachin's stem cells in Bhargav's blood. Soon, his blood was free of cancerous cells.
Ashok spent Rs 25 lakhs for Bhargav's bone marrow transplant procedure and raised money by selling his ancestral land in Rajkot.
Datri has 80,000 voluntary donors who have pledged their marrow since 2009. But the demand for marrow is very high. Up to one lakh people get blood cancer every year, a sizeable chunk of whom can be cured only through bone marrow transplant. "We have up to 2,500 patients on list, waiting to receive bone marrow, but have not been able to find a match for them. We get 15-20 patients every day who enroll for want of marrow. Many patients die on waiting list. More Indians need to come up and pledge their bone marrow," said Rajagopal.

Tiny hair follicle holds big clues about the life and death of stem cells
By daniellenierenberg
Inside the microscopic world of the mouse hair follicle, Yale Cancer Center researchers have discovered big clues about how stem cells regenerate and die. These findings, reported in the journal Nature, could lead to a better understanding of how the stem cell pool is maintained or altered in tissues throughout the body.
Stem cells are undifferentiated cells that replenish themselves and based on their tissue location can become specialized cells such as blood or skin cells. The hair follicle is an ideal site for exploring stem cell behavior because it has distinct and predictable oscillations in the number and behavior of stem cells, said the study's lead author Kailin R. Mesa, a third-year doctoral student in the lab of Valentina Greco, associate professor of genetics, cell biology and dermatology.
Using live microscopic imaging to track stem cell behavior in the skin of living mice, researchers observed that the stem cell niche, or surrounding area, played a critical role in whether stem cells grow or die.
"Prior to this, it wasn't clear whether stem cell regulation was intrinsic or extrinsic, and now we know it is external in that the niche instructs the stem cells," Mesa said. "In terms of cancer, we can next explore how we might perturb or change the niche in hopes of affecting the growth of cancer stem cells."
Also, researchers were surprised to find that the stem cells within the pool fed on other dying stem cells. This reveals a mechanism for removing dead cells, a process previously observed in mammary glands but never in the skin.

Dr. Owen Witte recognized with AACR G.H.A. Clowes Memorial Award
By raymumme
PHILADELPHIA -- The American Association for Cancer Research (AACR) is honoring Owen N. Witte, MD, founding director of the Eli & Edythe Broad Center of Regenerative Medicine & Stem Cell Research and distinguished professor of microbiology, immunology, and molecular genetics at the University of California, Los Angeles, with the 55th annual AACR G.H.A. Clowes Memorial Award at the AACR Annual Meeting 2015, to be held in Philadelphia, April 18-22.
Witte, who is also a Howard Hughes Medical Institute investigator and an elected fellow of the AACR Academy, is being recognized for his many contributions to the understanding of human leukemias, immune disorders, and epithelial cancer stem cells. Witte's work, which contributed to the development of several approved targeted therapies, has transformed the lives of patients with Philadelphia chromosome-positive leukemias and B-cell malignancies. He will present his lecture, "Finding Therapeutic Targets for Aggressive Prostate Cancer," Monday, April 20, 5:30 p.m. ET, in the Grand Ballroom of the Pennsylvania Convention Center.
The AACR and Eli Lilly and Company established the G.H.A. Clowes Memorial Award in 1961 to honor Dr. G.H.A. Clowes, a founding member of the AACR and research director at Eli Lilly. This award recognizes an individual with outstanding recent accomplishments in basic cancer research.
Witte's innovative work helped revolutionize modern cancer treatment by defining tyrosine kinases as crucial drug targets in human disease. Most notably, he pinpointed the molecular consequences of the Philadelphia (Ph) chromosome abnormality present in chronic myelogenous leukemia (CML) and related types of leukemia and defined the tyrosine kinase activity of the ABL gene product. These findings played a crucial role in the subsequent development of ABL kinase-targeted therapies, including imatinib (Gleevec), which remains the front-line treatment for Ph-positive CML.
In addition to his research involving ABL, Witte also co-discovered Bruton agammaglobulinemia tyrosine kinase (BTK). This particular kinase is essential for B-cell maturation and when mutated, results in the onset of the immunodeficiency disease, X-linked agammagloblulinemia. Recent studies involving this protein have resulted in the U.S. Food and Drug Administration approval of ibrutinib (Imbruvica), a selective BTK inhibitor, for the treatment of chronic lymphocytic leukemia mantle cell lymphoma, and Waldenstrm macroglobulinemia.
More recently, Witte's work has focused on defining the epithelial stem cell populations that contribute to prostate cancer. He is currently using mass spectrometry approaches to identify kinases that could be potential therapeutic targets for human prostate cancer.
"Much progress has been made in the area of personalized cancer medicine due to the dedication of scientists and physicians around the world, many of whom I've had the pleasure of working with through the AACR's innovative initiatives," said Witte. "But much more work is needed as we seek to understand cancer, which is not a single disease but rather many diseases that develop differently. I thank the AACR for their leadership in this effort and am honored to receive the Clowes Memorial Award."
An active AACR member, Witte has served on the AACR board of directors and several grant review committees. He is a past recipient of the AACR-Richard and Hinda Rosenthal Award and a co-leader of the Stand Up to Cancer Dream Team: Targeting Adaptive Pathways in Metastatic Treatment-Resistant Prostate Cancer. Additionally, he is also serving an appointed term on the President's Cancer Panel.
Witte has been recognized throughout his career with numerous honors. He has received the Nakahara Memorial Lecture Prize, the Cotlove Lectureship from the Academy of Clinical Laboratory Physicians and Scientists, the de Villiers International Achievement Award from the Leukemia and Lymphoma Society, the Warren Alpert Prize, and is elected member of the Institute of Medicine, National Academy of Sciences, and fellow of the American Academy of Arts and Sciences and the American Academy of Microbiology.
Witte received his medical degree from Stanford University School of Medicine in California, and was a postdoctoral fellow at the Center for Cancer Research at the Massachusetts Institute of Technology in Cambridge. He joined the UCLA faculty in 1980.

Stem Cells for Paralysis: First of Its Kind Study
By JoanneRUSSELL25
SAN DIEGO. (Ivanhoe Newswire) -- According to the Christopher and Dana Reeve Foundation, nearly one in 50 people is living with paralysis. Until now, there wasn't much hope. But a new study involving stem cells has doctors and patients excited.
Two years ago, Brenda Guerra's life changed forever.
Guerra told Ivanhoe, They told me that I went into a ditch and was ejected out of the vehicle.
The accident left the 26-year-old paralyzed from the waist down, and confined to a wheelchair.
I don't feel any of my lower body at all she said.
Guerra has traveled from Kansas to UC San Diego to be the first patient to participate in a ground-breaking safety trial, testing stem cells for paralysis.
Joseph D. Ciacci, MD, Professor of Neurosurgery at UC San Diego told Ivanhoe, We are directly injecting the stem cells into the spine.
The stem cells come from fetal spinal cords. The idea is when they're transplanted they will develop into new neurons and bridge the gap created by the injury by replacing severed or lost nerve connections. They did that in animals and doctors are hoping for similar results in humans. The ultimate goal is to help people like Brenda walk again.
The ability to walk is obviously a big deal not only in quality of life issues, but it also affects your survival long-term Dr. Ciacci said.

WKU plans bone marrow registry drive

Chris Goodman said its one of the most rewarding things hes ever done.
His stem cells reside inthe blood of a woman hes never met.
Goodman, a junior at Western Kentucky University, is working with a drive sponsored byWKU Greek Life and WKU student-athletesto register people for potential bone marrow donations. Donated stem cells, which are extracted from bone marrow, can be used to help people recover from serious illnesses.
The drive is April 20-22 at Raymond B. Preston Health and Activities Center. The hours are from 10 a.m. to 6 p.m.April 20 and 21 and from 10 a.m.to 7 p.m.April 22 in the Blue Court. Goodman will be working at the drive April 21, he said.
Goodman, 20, is from Knoxville, Tenn., and is a backstroke swimmer for WKU. Hes studying speech pathology and communications disorders and wants someday to work with kids who have speech difficulties.
A five-minute swab of your cheek could help save a life, Goodman said.
Goodman received a short note from the woman who was helped by his donation.
The letter I received from my patient was one which was very short in length but nonetheless very impactful, he said in an email. She and her family were very grateful that a complete stranger would give so much to someone they dont know.
His journey to becoming a bone marrow donator began when he registered withDelete Blood Cancer DKMSas a potential donor in April 2013. In October, Delete Blood Cancer sent him to Washington, D.C., and he donated stem cells during a five-day process.
He watched movies while sitting in his hospital bed as the procedure occurred. Having never even given a blood donation before, Goodman said the process did leave him a bit weak, although he participated in a swim meet for WKU within a week following the procedure, he said.
