Mesenchymal Stem Cells | National Stem Cell Foundation

Posted: Published on November 1st, 2013

Mesenchymal (stromal) stem cells give rise to a variety of cell types, including bone cells (osteocytes), cartilage cells (chondrocytes), fat cells (adipocytes), pancreatic islet cells and connective tissue cells such as those found in tendons. Mesenchymal stem cells can be found in umbilical cord blood, fat, muscleand the pulp of baby teeth. They are referred to as multipotent cells because they can develop into multiple tissues, but they do not have the capacity to reconstitute an entire organ. An extremely rich source of mesenchymal stem cells is the developing tooth bud of the mandibular (lower) third molar, or wisdom tooth. While considered multipotent, these stem cells may prove to be pluripotent, capable of generating all tissue types. The stem cells found in developing third molars eventually form enamel, dentin, blood vessels, dental pulp, nervous tissue and a minimum of 29 different unique tissues and organs. Because of extreme ease in collection at 810 years of age, they will probably constitute a major source for personal banking, research and multiple therapies. Adipose (fat) tissue is one of the richest sources of mesenchymal stem cells. There are 500 times more mesenchymal stem cells in 1 gram of fat than there are in … Continue reading

Mesenchyme – Wikipedia, the free encyclopedia

Posted: Published on November 1st, 2013

Mesenchyme, also called mesenchymal connective tissue, is a type of undifferentiated loose connective tissue that is derived mostly from mesoderm, although some is derived from other germ layers; e.g. neural crest cells and thus originates from the ectoderm. Most embryologists use the term "mesenchyme" only for those cells that develop from the mesoderm.[citation needed] The term mesenchyme essentially refers to the morphology of embryonic cells, however, they do persist as stem cells into adulthood. Mesenchymal cells are able to develop into the tissues of the lymphatic and circulatory systems, as well as connective tissues throughout the body, such as bone and cartilage. A sarcoma is a cancer of mesenchymal cells.[1][2] Mesenchyme is characterized morphologically by a prominent ground substance matrix containing a loose aggregate of reticular fibrils and unspecialized cells.[3] Mesenchymal cells can migrate easily, in contrast to epithelial cells, which lack mobility and are organized into closely adherent sheets, are polygonal in shape, and are polarized in an apical-basal orientation.

Mesenchymal stem cell – Wikipedia, the free encyclopedia

Posted: Published on November 1st, 2013

Mesenchymal stem cells, or MSCs, are multipotent stromal cells that can differentiate into a variety of cell types,[1] including: osteoblasts (bone cells),[2]chondrocytes (cartilage cells),[3] and adipocytes (fat cells). This phenomenon has been documented in specific cells and tissues in living animals and their counterparts growing in tissue culture. While the terms Mesenchymal Stem Cell and Marrow Stromal Cell have been used interchangeably, neither term is sufficiently descriptive as discussed below: The youngest, most primitive MSCs can be obtained from the umbilical cord tissue, namely Wharton's jelly and the umbilical cord blood. However the MSCs are found in much higher concentration in the Whartons jelly compared to the umbilical cord blood, which is a rich source of hematopoietic stem cells. The umbilical cord is easily obtained after the birth of the newborn, is normally thrown away and poses no risk for collection. The umbilical cord MSCs have more primitive properties than other adult MSCs obtained later in life, which might make them a useful source of MSCs for clinical applications. An extremely rich source for mesenchymal stem cells is the developing tooth bud of the mandibular third molar. While considered multipotent, they may prove to be pluripotent. The stem cells eventually … Continue reading

Funding for muscle-wasting condition

Posted: Published on November 1st, 2013

1 November 2013 Last updated at 09:20 ET By Marianne Taylor BBC Scotland news Families of children with a devastating muscle-wasting condition have welcomed funding for a new medical expert. Duchenne muscular dystrophy, which affects about 200 children and young people in Scotland, is incurable and causes severe disability. A shortage of experts makes it difficult for potential new treatments to reach those with the condition. Parents said the funding would help their children lead more fulfilling lives. We need to ensure any treatments developed by scientists make it to the people who desperately need them Duchenne, which mostly affects boys, causes muscles to weaken and waste over time, leading to increasing and severe disability. Few born with the condition - which affects about one in 3,600 boys - currently live to the age of 30 due to damage to heart and breathing muscles. A new funding partnership between the Chief Scientist Office and charities Muscular Dystrophy Campaign and Action Duchenne, will provide 75,000 a year for three years for a medical training fellow to research potential treatments and work directly with children. It is hoped the new expert will be in post by autumn 2014. Originally posted here: Funding … Continue reading

Important breakthrough in identifying effect of epilepsy treatment

Posted: Published on November 1st, 2013

PUBLIC RELEASE DATE: 31-Oct-2013 Contact: Tanya Gubbay tanya.gubbay@rhul.ac.uk Royal Holloway, University of London 50 years after valproate was first discovered, research published today in the journal Neurobiology of Disease, reports how the drug works to block seizure progression. Valproate (variously labelled worldwide as Epilim, Depacon, Depakene, Depakote, Orlept, Episenta, Orfiril, and Convulex) is one of the world's most highly prescribed treatments for epilepsy. It was first discovered to be an effective treatment for epilepsy, by accident, in 1963 by a group of French scientists. In thousands of subsequent experiments, animals have been used to investigate how valproate blocks seizures, without success. Scientists from Royal Holloway University and University College London have now identified how valproate blocks seizures in the brain, by using a simple amoeba. "The discovery of how valproate blocks seizures, initially using the social amoeba Dictyostelium, and then replicated using accepted seizure models, highlights the successful use of non-animal testing in biomedical research," said Professor Robin Williams from the School of Biological Sciences at Royal Holloway. "Sodium valproate is one of the most effective antiepileptic drugs in many people with epilepsy, but its use has been limited by side-effects, in particular its effect in pregnant women on the … Continue reading

Applied Behavior Analysis (ABA) | What is Autism?/Treatment …

Posted: Published on November 1st, 2013

Autism Speaks Autism Treatment Network (ATN) now has a tool kit to help parents work with their childrens applied behavior analysts. (Learn more and download it here.) Although the tool kit was developed with children and teens in mind, it also contains helpful information for those wanting to better understand and support ABA therapy for an adult with autism. Behavior analysis is a scientifically validated approach to understanding behavior and how it is affected by the environment. In this context, behavior" refers to actions and skills. "Environment" includes any influence physical or social that might change or be changed by one's behavior. On a practical level, the principles and methods of behavior analysis have helped many different kinds of learners acquire many different skills from healthier lifestyles to the mastery of a new language. Since the 1960s, therapists have been applying behavior analysis to help children with autism and related developmental disorders. Behavior analysis focuses on the principles that explain how learning takes place. Positive reinforcement is one such principle. When a behavior is followed by some sort of reward, the behavior is more likely to be repeated. Through decades of research, the field of behavior analysis has developed many … Continue reading

Autism Fact Sheet: National Institute of Neurological Disorders …

Posted: Published on November 1st, 2013

Autism spectrum disorder (ASD) is a range of complex neurodevelopment disorders, characterized by social impairments, communication difficulties, and restricted, repetitive, and stereotyped patterns of behavior. Autistic disorder, sometimes called autism or classical ASD, is the most severe form of ASD, while other conditions along the spectrum include a milder form known as Asperger syndrome, and childhood disintegrative disorder and pervasive developmental disorder not otherwise specified (usually referred to as PDD-NOS). Although ASD varies significantly in character and severity, it occurs in all ethnic and socioeconomic groups and affects every age group. Experts estimate that 1 out of 88 children age 8 will have an ASD (Centers for Disease Control and Prevention: Morbidity and Mortality Weekly Report, March 30, 2012). Males are four times more likely to have an ASD than females. The hallmark feature of ASD is impaired social interaction. As early as infancy, a baby with ASD may be unresponsive to people or focus intently on one item to the exclusion of others for long periods of time. A child with ASD may appear to develop normally and then withdraw and become indifferent to social engagement. Children with an ASD may fail to respond to their names and often … Continue reading

Autism therapies – Wikipedia, the free encyclopedia

Posted: Published on November 1st, 2013

Autism therapies attempt to lessen the deficits and abnormal behaviours associated with autism and other autism spectrum disorders (ASD), and to increase the quality of life and functional independence of autistic individuals, especially children. Treatment is typically tailored to the child's needs. Treatments fall into two major categories: educational interventions and medical management. Training and support are also given to families of those with ASD.[2] Studies of interventions have methodological problems that prevent definitive conclusions about efficacy.[3] Although many psychosocial interventions have some positive evidence, suggesting that some form of treatment is preferable to no treatment, the methodological quality of systematic reviews of these studies has generally been poor, their clinical results are mostly tentative, and there is little evidence for the relative effectiveness of treatment options.[4] Intensive, sustained special education programs and behavior therapy early in life can help children with ASD acquire self-care, social, and job skills,[2] and often can improve functioning, and decrease symptom severity and maladaptive behaviors;[5] claims that intervention by around age three years is crucial are not substantiated.[6] Available approaches include applied behavior analysis (ABA), developmental models, structured teaching, speech and language therapy, social skills therapy, and occupational therapy.[2] Educational interventions have some effectiveness … Continue reading

How Is Autism Treated? | What is Autism? | Autism Speaks

Posted: Published on November 1st, 2013

Image Courtesy UNC Medical Center Each child or adult with autism is unique and, so, each autism intervention plan should be tailored to address specific needs. Intervention can involve behavioral treatments, medicines or both. Many persons with autism have additional medical conditions such as sleep disturbance, seizures and gastrointestinal (GI) distress. Addressing these conditions can improve attention, learning and related behaviors. (Learn more about Treatment of Autisms Core Symptoms and Treatment of Associated Medical Conditions.) Early intensive behavioral intervention involves a child's entire family, working closely with a team of professionals. In some early intervention programs, therapists come into the home to deliver services. This can include parent training with the parent leading therapy sessions under the supervision of the therapist. Other programs deliver therapy in a specialized center, classroom or preschool. (Learn more about Early Intervention.) Typically, different interventions and supports become appropriate as a child develops and acquires social and learning skills. As children with autism enter school, for example, they may benefit from targeted social skills training and specialized approaches to teaching. Adolescents with autism can benefit from transition services that promote a successful maturation into independence and employment opportunities of adulthood. (Learn more about Transition in … Continue reading
