Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.

Injuries to DNA that introduce deviations from its normal, intact structure and which may, if left unrepaired, result in a MUTATION or a block of DNA REPLICATION. These deviations may be caused by physical or chemical agents and occur by natural or unnatural, introduced circumstances. They include the introduction of illegitimate bases during replication or by deamination or other modification of bases; the loss of a base from the DNA backbone leaving an abasic site; single-strand breaks; double strand breaks; and intrastrand (PYRIMIDINE DIMERS) or interstrand crosslinking. Damage can often be repaired (DNA REPAIR). If the damage is extensive, it can induce APOPTOSIS.
One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.

Adult neural stem/progenitor cells in neurodegenerative repair. (1/1106)

Although the mammalian brain has long been thought to be entirely postmitotic, the recent discovery has confirmed an existence of neural stem or progenitor cells in various regions of the adult mammalian brain. Like embryonic stem cells, adult neural progenitor cells possess the capacity of self-renewal and differentiation potential for neurogenesis or gliogenesis. In addition to the subventricular zone and hippocampus where active cell division naturally occurs, adult neural progenitors with neurogenic potential exist in the striatum and the vicinity of dopaminergic neurons in the substantia nigra. Normally, progenitors in those regions proliferate at a low level, and most proliferated cells remain uncommitted. In response to the selective lesion of nigrostriatal dopaminergic pathway by the neurotoxins, such as 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) or 6-hydroxydopamine, progenitors in the injured areas markedly increase their proliferation rate. Depending upon the magnitude and kinetics of the lesion, neurogenesis and gliogenesis were induced in the lesion sites at varying extents. A large number of growth and neurotrophic factors influence proliferation and/or differentiation of progenitor cells under normal and lesioned conditions. Some factors (epidermal and basic fibroblast growth factors and brain-derived neurotrophic factor) are facilitatory, while others (usually bone morphogenetic proteins) are inhibitory, for controlling division and fate of neuronal or glial progenitors. Expression of endogenous factors and their respective receptors in existing and newborn cells are also subject to be altered by the lesion. These genomic responses are considered to be important elements for the formation of a local molecular niche for a given phenotypic cell regeneration. Taken together, adult neural progenitor cells in the nigrostriatal dopaminergic system have the ability to respond to the lesion to repopulate missing cells. The regenerative neuro- or gliogenesis in situ can, at least in part, endogenously compensate injured neural elements, and achieve a self-repair of neurodegenerative disorders such as Parkinson's disease.  (+info)

Differentiation versus plasticity: fixing the fate of undetermined adult stem cells. (2/1106)

Adult mesenchymal stem cells own a considerable plasticity, which enables them to respond to various extra- and intracellular cues and exert, at least partially, various differentiation pathways. Recently, we have shown that multipotent adult stem cells (MASCs) derived from the mouse bone marrow (mBM-MASCs) consist of distinct cell populations that have similar differentiation abilities but differ in the expression of several stem cell markers. Despite their remarkable developmental potential MASCs seem to miss crucial components to complete specific differentiation programs necessary to acquire a fully functional phenotype. A thorough analysis of active and inactive regulatory circuits in multipotent adult stem cells might lead the way to a controlled programming of these cells and rational therapeutic applications.  (+info)

The consensus of the task force of the European Society of Cardiology concerning the clinical investigation of the use of autologous adult stem cells for repair of the heart. (3/1106)

A task force has been established by the European Society of Cardiology to investigate the role of progenitor/stem cell therapy in the treatment of cardiovascular disease. This article is the consensus of this group, of what clinical studies are needed in this field, and the challenges to be addressed in the translation of progenitor/stem cell biology to repair of the heart.  (+info)

X inactivation patterns of closely, but not distantly, related cells are highly correlated: little evidence for stem cell plasticity in normal females. (4/1106)

The early, random nature of X inactivation should cause related cells to have similar, but distinctive, active X chromosomes. We assessed the frequency of stem cell plasticity using X inactivation proportions (XIPs), determined at the human androgen receptor locus, in paired tissue samples from healthy individuals. Tissues sampled were stomach (n = 18 informative females), duodenum (n = 18), colon (n = 10) with corresponding peripheral blood samples (n = 33), and varicose veins (n = 28) with corresponding T cells (n = 26) and peripheral blood granulocytes (n = 25). XIPs from samples thought to have common stem cell origins were highly correlated: multiple samples from single vein, r = .80 (n = 24); T cells versus granulocytes, r = .67 (n = 23); duodenum versus stomach, r = .63 (n = 12). Blood cells and vessels are derived from a common hemangioblast, but XIP correlations were moderate or poor: vein versus T cells, r = .42 (n = 26); vein versus granulocytes, r = .11 (n = 25). X inactivation is believed to be a late process in gut, especially hind-gut, with corresponding independence from blood precursors. Correlations with blood cells were low: stomach, r = .23 (18); duodenum, r = .21 (18); colon, r = .034 (10). Any crossover of stem cells between different organs during adult life should increase correlations with age; no such increase was seen. This study confirms that XIPs can be used to track stem cell populations, provides a theoretical basis for the power of such studies, and indicates that hemopoietic stem cell plasticity is, at most, uncommon in normal humans.  (+info)

A role for angiotensin-converting enzyme in the characterization, enrichment, and proliferation potential of adult murine pituitary colony-forming cells. (5/1106)

Recently, we described a rare cell type within the adult murine pituitary gland with progenitor cell hallmarks (PCFCs). PCFCs are contained exclusively within a subpopulation of cells that import fluorescent beta-Ala-Lys-Nepsilon-AMCA (7-amino-4-methylcoumarin-3-acetic acid). Herein, we investigate the utility of cell surface molecules angiotensin-converting enzyme (ACE) and stem cell antigen-1 (Sca-1) to further enrich for PCFCs. ACE and Sca-1 were expressed on 61% and 55% of AMCA(+)CD45(-)CD31(-) cells, respectively, and coexpressed on 38%. ACE(+)Sca-1(+)AMCA(+) cells enriched for PCFCs by 195-fold over unselected cells. ACE(+)AMCA(+) cells enriched for PCFCs by 170-fold, and colonies were twofold larger than for AMCA(+) selection alone. Conversely, ACE(-)-selected cells reduced both colony-forming activity and size. Notably, colonies generated from AMCA(+) cells obtained from ACE(null) mice were 2.7-fold smaller than for wild-type mice. These data identify ACE as a previously unrecognized marker of PCFCs and suggest that ACE is functionally important for PCFC proliferation. Anatomically, the cells that imported AMCA and expressed ACE were situated in the marginal epithelial cell layer of the pituitary cleft and in the adjacent subluminal zone, thus supporting previous proposals that the luminal zone is a source of precursor cells in the adult pituitary.  (+info)

Regrow or repair: potential regenerative therapies for the kidney. (6/1106)

Regenerative medicine is being heralded in a similar way as gene therapy was some 15 yr ago. It is an area of intense excitement and potential, as well as myth and disinformation. However, with the increasing rate of end-stage renal failure and limited alternatives for its treatment, we must begin to investigate seriously potential regenerative approaches for the kidney. This review defines which regenerative options there might be for renal disease, summarizes the progress that has been made to date, and investigates some of the unique obstacles to such treatments that the kidney presents. The options discussed include in situ organ repair via bone marrow recruitment or dedifferentiation; ex vivo stem cell therapies, including both autologous and nonautologous options; and bioengineering approaches for the creation of a replacement organ.  (+info)

Cell cycle quiescence of early lymphoid progenitors in adult bone marrow. (7/1106)

Lymphocyte production in bone marrow (BM) requires substantial cell division, but the relationship between largely quiescent stem cells and dividing lymphoid progenitors is poorly understood. Therefore, the proliferation and cell cycle status of murine hematopoietic progenitors that have just initiated the lymphoid differentiation program represented the focus of this study. Continuous bromo-2'-deoxyuridine (BrdU) incorporation and DNA/RNA analysis by flow cytometry revealed that a surprisingly large fraction of RAG-1(+)c-kit(hi) early lymphoid progenitors (ELPs) and RAG-1(+)c-kit(lo) pro-lymphocytes (Pro-Ls) in adult BM were in cell cycle quiescence. In contrast, their counterparts in 14-day fetal liver actively proliferated. Indeed, the growth fraction (cells in G(1)-S-G(2)-M phases) of fetal ELPs was on average 80% versus only 30% for adult ELPs. After 5-fluorouracil treatment, as many as 60% of the adult ELP-enriched population was in G(1)-S-G(2)-M and 34% incorporated BrdU in 6 hours. Transcripts for Bcl-2, p21Cip1/Waf1, and p27 Kip1 cell cycle regulatory genes correlated inversely well with proliferative activity. Interestingly, adult lymphoid progenitors in rebound had the high potential for B lymphopoiesis in culture typical of their fetal counterparts. Thus, lymphocyte production is sustained during adult life by quiescent primitive progenitors that divide intermittently. Some, but not all, aspects of the fetal differentiation program are reacquired after chemotherapy.  (+info)

Multipotent adult progenitor cells from swine bone marrow. (8/1106)

We show that multipotent adult progenitor cells (MAPCs) can be derived from both postnatal and fetal swine bone marrow (BM). Although swine MAPC (swMAPC) cultures are initially mixed, cultures are phenotypically homogenous by 50 population doublings (PDs) and can be maintained as such for more than 100 PDs. swMAPCs are negative for CD44, CD45, and major histocompatibility complex (MHC) classes I and II; express octamer binding transcription factor 3a (Oct3a) mRNA and protein at levels close to those seen in human ESCs (hESCs); and have telomerase activity preventing telomere shortening even after 100 PDs. Using quantitative-reverse transcription-polymerase chain reaction (Q-RT-PCR), immunofluorescence, and functional assays, we demonstrate that swMAPCs differentiate into chondrocytes, adipocytes, osteoblasts, smooth muscle cells, endothelium, hepatocyte-like cells, and neuron-like cells. Consistent with what we have shown for human and rodent MAPCs, Q-RT-PCR demonstrated a significant upregulation of transcription factors and other lineage-specific transcripts in a time-dependent fashion similar to development. When swMAPCs were passaged for 3-6 passages at high density (2,000-8,000 cells per cm(2)), Oct3a mRNA levels were no longer detectable, cells acquired the phenotype of mesenchymal stem cells (CD44(+), MHC class I(+)), and could differentiate into typical mesenchymal lineages (adipocytes, osteoblasts, and chondroblasts), but not endothelium, hepatocyte-like cells, or neuron-like cells. Even if cultures were subsequently replated at low density (approximately 100-500 cells per cm(2)) for >20 PDs, Oct3a was not re-expressed, nor were cells capable of differentiating to cells other than mesenchymal-type cells. This suggests that the phenotype and functional characteristics of swMAPCs may not be an in vitro culture phenomenon.  (+info)

Simply put, adult stem cells, when taken as a whole, have the potential to grow into any of the bodys more than 200 cell types.. Adult Stem Cells are Ethical. Because adult stem cells are derived from adult tissues, there are no ethical dilemmas related to this type of therapy. Furthermore, research continues to show adult stem cells have far greater potential than embryonic stem cells to treat a variety of disease and conditions, including cancer, heart disease and neurodegenerative diseases.. It is only through continued research and clinical trials in patients that scientists and doctors will identify the different applications for adult stem cell therapy.. Adult Stem Cell Therapy. One of the oldest forms of adult stem cell treatment are bone marrow transplants, which have been practiced since the late 1960s. In the case of a patient suffering with a blood cancer such as leukemia, a bone marrow transplant ( ...
An adult stem cell is thought to be an undifferentiated cell, found among differentiated cells in a tissue or organ that can renew itself and can differentiate to yield some or all of the major specialized cell types of the tissue or organ.. The primary roles of adult stem cells in a living organism are to maintain and repair the tissue in which they are found.. Scientists also use the term somatic stem cell instead of adult stem cell, where somatic refers to cells of the body (not the germ cells, sperm or eggs). Unlike embryonic stem cells, which are defined by their origin (the inner cell mass of the blastocyst), the origin of adult stem cells in some mature tissues is still under investigation.. Research on adult stem cells has generated a great deal of excitement. Scientists have found adult stem cells in many more tissues than they once thought possible. This finding has led researchers and clinicians to ask whether adult stem cells could be used for transplants.. In fact, adult ...
Adult stem cells are multipotent, semi-differentiated, cells that exist in all tissues. Adult stem cell, however, is not the preferred term used in the field to refer to them-developmental biologists will usually refer to them as tissue resident stem cells or as a specific cell type (often referencing the genes they express). They function to maintain tissue homeostasis by dividing to replace damaged or senescent somatic cells. The two most well-studied examples of adult stem cells are the hematopoietic stem cells, which give rise to blood cells, and the intestinal crypt stem cells, which give rise to the intestinal epithelium.[1] As multipotent cells, most adult stem cell types can generate cells of several different types. However, because they are already epigenetically programmed to favor a particular fate, they generally cannot generate cell types outside of their lineage without genetic manipulation. Identifying and characterizing stem cells within all adult tissues is an area of much ...
Definition of Adult stem cell in the Legal Dictionary - by Free online English dictionary and encyclopedia. What is Adult stem cell? Meaning of Adult stem cell as a legal term. What does Adult stem cell mean in law?
Adult stem cell treatments have been used for many years to successfully treat leukemia and related bone/blood cancers utilizing bone marrow transplants.[49] The use of adult stem cells in research and therapy is not considered as controversial as the use of embryonic stem cells, because the production of adult stem cells does not require the destruction of an embryo. Early regenerative applications of adult stem cells has focused on intravenous delivery of blood progenitors known as Hematopetic Stem Cells (HSCs). CD34+ hematopoietic Stem Cells have been clinically applied to treat various diseases including spinal cord injury,[50] liver cirrhosis [51] and Peripheral Vascular disease.[52] Research has shown that CD34+ hematopoietic Stem Cells are relatively more numerous in men than in women of reproductive age group among spinal cord Injury victims.[53] Other early commercial applications have focused on Mesenchymal Stem Cells (MSCs). For both cell lines, direct injection or placement of cells ...
5 Misconceptions About Adult Stem Cells. by Lake Nona Medical Arts. If you feel confused about adult-derived stem cells, youre not alone. Many people are unclear of how cells differ based on whether they are adult, embryonic, or come from the umbilical cord of a newborn baby. This confusion causes them to believe common misconceptions that could prevent them from realizing the full benefit of adult stem cells.. An adult stem cell is undifferentiated, which means that it is located in differentiated cells in the major organs and tissues of the body. It is capable of self-renewal and can yield to some or all the most prominent types of cells in an organ or tissue. The main job of adult stem cells is to repair and maintain the tissues where they are located.. Even though adult-derived stem cells and stem cells in general offer tremendous promise in the treatment of previous incurable diseases, many misconceptions persist about them. Below are five of the most common myths debunked.. ...
Dr. David Prentice, Adjunct Professor of Molecular Genetics and an international expert on the stem cell topic, recently testified several times to Kansas lawmakers on this developing field. Prentice quoted recent science and medical journals demonstrating that:. *1 in 200 Americans will undergo an Adult Stem Cell (ASC) transplant in their lifetime;. *over 60,000 ASC transplants occur globally each year;. *there are over 2,600 ongoing, or completed, FDA-approved ASC trials. Over 60,000 people around the globe are treated each year with adult stem cells, Prentice told NRL News Today. The diseases and conditions successfully treated by adult stem cells, as shown by published scientific evidence, continue to expand, with published success for numerous cancers, spinal cord injury, heart damage, multiple sclerosis, sickle cell anemia, and many others. Adult stem cells also have a proven track record for success at saving lives and improving health on a daily basis.. Dr. Smith gave an interview to ...
Numerous previous studies have shown that adult stem cells can facilitate repair of damaged heart muscle. Now an Israeli team has developed a method to stimulate bone marrow adult stem cells to increase their ability to help restore heart function. The new method uses laser-treated bone marrow adult stem cells to help restore heart function. The technique using low-level laser light is called shining. In the mouse study to show the techniques effectiveness, the team shone laser light directly on bone marrow, and then tracked the bone marrow adult stem cells and the repair of the mouse hearts after treatment. ...
Multiple sclerosis (MS) treatment with adult stem cells also showed multiple positive results over the past year. A team of scientists from Thessaloniki, Greece, showed that chemotherapy followed by adult stem cell transplant can stop progression of aggressive MS. The team observed a group of 35 patients who received transplants of their own bone marrow adult stem cells after being treated with chemotherapy to wipe out the rogue immune cells that were attacking their nervous system and causing their MS. An average of 11 years after their transplants, 25% of the patients in Greece have not seen their disease progress. And a U.K. team led by Dr. Neil Scolding showed that a simple intravenous infusion of the patients adult stem cells, without using chemotherapy, could work to improve MS patient symptoms ...
Peyton Manning, quarterback for the Indianapolis Colts and four-time NFL MVP, apparently went to Europe to get an adult stem cell procedure on his neck, according to a report Sunday by Jay Glazer of Fox Sports. Manning has had three surgeries on his neck in the last 19 months, Little detail was available, but the information indicates that the procedure may have used adipose (fat) derived adult stem cells from Mannings own body; this autologous procedure (using your own adult stem cells) bypasses any problems of transplant rejection and is relatively safe. Mannings adult stem cells may have then been ...
New research has been published confirming that multipotent adult progenitor cells (MAPCs), a type of adult stem cell, can repair and restore damaged blood systems in mice. Catherine Verfaillie and colleagues at the University of Minnesota first described these novel stem cells in 2002, but other teams have had difficulty in replicating the work. In a new paper published in the journal Experimental Medicine, Verfaillie has worked with a leading sceptic of the research, Dr Irving Weissman of Stanford University, to show that the cells can be grown in the laboratory and successfully transplanted into animals. Dr Weissman, who directs Stanfords Institute for Stem Cell Biology and Regenerative Medicine, rigorously examined the data and concluded, These experiments point to potential precursors of blood forming stem cell in an unexpected population of cultured cells.. Usually adult stem cells are precursors to populations of particular cell types, for instance neural stem cells may be ...
While administration of ex vivo culture-expanded stem cells has been used to study immunosuppressive mechanisms in multiple models of autoimmune diseases, less is known about the uncultured, nonexpanded stromal vascular fraction (SVF)-based therapy. The SVF is composed of a heterogeneous population of cells and has been used clinically to treat acute and chronic diseases, alleviating symptoms in a range of tissues and organs. In this study, the ability of human SVF cells was compared with culture-expanded adipose stem cells (ASCs) and bone-derived marrow stromal cells (BMSCs) as a treatment of myelin oligodendrocyte glycoprotein (35-55)-induced experimental autoimmune encephalitis in C57Bl/6J mice, a well-studied multiple sclerosis model (MS). A total of 1 × 106 BMSCs, ASCs, or SVF cells were administered intraperitoneally concomitantly with the induction of disease. Mice were monitored daily for clinical signs of disease by three independent, blinded investigators and rated on a scale of 0 to 5.
Human MSCs, or closely related cells, are currently being tested in a number of animal models for human diseases [18, 19], and several clinical trials with the cells have been initiated [20-22]. For most of these experiments and trials, the MSCs were prepared with a standard protocol in which nucleated cells were isolated from a bone marrow aspirate with a density gradient, and then both enriched and expanded in the presence of fetal calf serum by their tight adherence to plastic tissue culture dishes. Cultures of human MSCs, unlike murine cells [23], become free of hematopoietic precursors after one or two passages and can be extensively expanded before they senesce. However, cultures of human MSCs are morphologically heterogeneous, even when cloned from single-cell-derived colonies [12, 24]. Moreover, the cultures undergo subtle changes as they are expanded, with a marked decrease in the rate of proliferation and multipotentiality [10, 24].. The difficulties in expanding human MSCs in culture ...
The standard of care treatment for acute myocardial infarction (AMI) usually includes immediate perfusion, optimal pain relief, oxygen, aspirin or other anti-coagulants, Beta-Blockers, nitrates and Ace-inhibitors. However, because salvaging the viable myocardium is dependent on early reperfusion, only a minority of patients will reach the hospital within the time-window for myocardial rescue. Thus, even if the patient manages their tobacco use, hypertension, lipid levels, diabetes, weight and exercise, many patients will go on to develop Congestive Heart Failure (CHF). Though the medical management for CHF may improve symptoms and slow disease progression, such treatment cannot restore a functioning myocardium. A therapy that could improve the myocardial remodeling process and reduce the incidence or severity of CHF following acute MI would provide a significant benefit. The characteristics and biologic activity of Prochymal®, along with a good safety profile in human trials to date, suggest ...

Also, a single adult stem cell should be able to generate a line of genetically identical cells-known as a clone-which then gives rise to all the appropriate differentiated cell types of the tissue. Scientists tend to show either that a stem cell can give rise to a clone of cells in cell culture, or that a purified population of candidate stem cells can repopulate the tissue after transplant into an animal. Recently, by infecting adult stem cells with a virus that gives a unique identifier to each individual cell, scientists have been able to demonstrate that individual adult stem cell clones have the ability to repopulate injured tissues in a living animal ...
使用成人幹細胞治療發性硬化症 December 14, 2009 The latest success story comes from Australia. Ben Leahy, 20, was in a wheelchair and experiencing vision problems when he was treated earlier in 2009. Ben is now walking after treatment with adult stem cells. The treatment involves isolating the patients bone marrow adult stem cells, giving the patient mild chemotherapy to destroy the rogue immune cells that are attacking the nervous system, then re-injecting the patients adult stem cells.. 之前最新的報導指出 一位罹患多發性硬化症的20歲澳大利亞小孩Ben Leahy, 他視力受損且無法行走只能坐在輪椅上.而在今年2009稍早的時候進行了成人幹細胞治療. 該治療包含了隔絕他的骨髓幹細胞, 並且給予溫和的化療來徹底摧毀不正常的免疫細胞, 然後再注入他自身的成人幹細胞..

Adult stem cells in the intestine and skin of mice can be induced to multiply massively by the introduction of a master gene regulatory protein derived from embryonic stem cells. This finding, reported in the May 6 Cell by Rudy Jaenisch and his colleagues at MIT, may provide a technique for expanding tissue-specific stem cells from adults for clinical use. While the study dealt only with epithelial cells, future studies will determine if the trick is useful for generating neural stem cells, a possibility that the researchers are very interested to explore, said Jaenisch. There is much optimism that neural stem cells may help to treat cell losses associated with a variety of neurodegenerative diseases, including Alzheimer disease (see ARF related news story and ARF news story).. The remarkable expansion of adult stem cells was induced by forced expression of the protein Oct-4, a transcription factor that is normally expressed in embryonic stem cells and is required for their pluripotency and ...
TY - JOUR. T1 - Adult stem cell plasticity. T2 - Will engineered tissues be rejected?. AU - Fang, Te Chao. AU - Alison, Malcolm R.. AU - Wright, Nicholas A.. AU - Poulsom, Richard. PY - 2004/6. Y1 - 2004/6. N2 - The dogma that adult tissue-specific stem cells remain committed to supporting only their own tissue has been challenged; a new hypothesis, that adult stem cells demonstrate plasticity in their repertoires, is being tested. This is important because it seems possible that haematopoietic stem cells, for example, could be exploited to generate and perhaps deliver cell-based therapies deep within existing nonhaematopoietic organs. Much of the evidence for plasticity derives from histological studies of tissues from patients or animals that have received grafts of cells or whole organs, from a donor bearing (or lacking) a definitive marker. Detection in the recipient of appropriately differentiated cells bearing the donor marker is indicative of a switch in phenotype of a stem cell or a ...
Adult stem cells are undifferentiated cells, found throughout the body after embryonic development, which multiply by cell division to replenish dying cells and regenerate damaged tissue. Adult stem cells support tissue and organ turnover throughout life by maintaining a delicate balance between apoptosis and tissue-specific cellular proliferation and differentiation.
In contrast to ES cells, when we inject the bone marrow stem cells into recipient animals, the bone marrow stem cells do not form teratomas [tumors containing many different tissue types], but respond to local cues and differentiate into blood cells as well as into epithelium of liver, gut, and lung.. In response to recent critics of the potential of adult stem cells, Verfaillies research shows in vitro that a single cell differentiates into cells of the three germ layers, that they were euploid (correct number of chromosomes) and that they never co-cultured the bone marrow cells with endothelial, neuronal or liver cells. Therefore, the in vitro observation cannot be the result of fusion. Verfaillie also shows that the chimerism is balanced and that engraftment occurs without selectable pressure.. Verfaillie said she believes that adult stem cells may hold therapeutic promise, but cautioned that a large number of studies is still required to fully characterize the potential of MAPCs. Side by ...
For many years, researchers have been seeking to understand the bodys ability to repair and replace the cells and tissues of some organs, but not others. After years of work pursuing the how and why of seemingly indiscriminant cell repair mechanisms, scientists have now focused their attention on adult stem cells. It has long been known that stem cells are capable of renewing themselves and that they can generate multiple cell types. Today, there is new evidence that stem cells are present in far more tissues and organs than once thought and that these cells are capable of developing into more kinds of cells than previously imagined. Efforts are now underway to harness stem cells and to take advantage of this new found capability, with the goal of devising new and more effective treatments for a host of diseases and disabilities. What lies ahead for the use of adult stem cells is unknown, but it is certain that there are many research questions to be answered and that these answers hold great ...
A considerable amount of controversy has arisen surrounding the use of embryonic stem cells to treat various conditions and diseases. This moral and ethical question may be avoided through the use of adult stem cells. However, some of us are unfamiliar with the benefits of these cells and why their adult counterparts may present an ideal option. It is a good idea to take a more in-depth look at both of these topics. How do Adult Stem Cells Work? Like embryonic stem cells, adult cells are not specialised. In other words, they have not formed one type of cell or another. This will allow them to differentiate later in their lifespan. By placing them into certain areas of the body, cells which are damaged or not present may be able to be regenerated. Where are they Found? Stem cells are found within a variety of locations throughout the body. Some of the most common areas where they are harvested include: The skin. Bone marrow. Blood vessels. Skeletal muscle. The liver. Obtaining these cells from an adult
Bone marrow (30 ± 5 mL) was harvested from the posterior iliac crest of healthy pigs. Mononuclear cells were separated from red cells by density gradient centrifugation with Ficoll Paque (density, 1.077 g/cm3). The buffy coat was collected and washed twice for 5 minutes at 1500 rpm. The cells are plated in α-MEM medium, containing HEPES, fetal bovine serum (10%), antibiotic solution (penicillin (10,000 U), streptomycin (10 mg)), amphotericin B (25 µg) /mL), L-glutamine (200 mM), and incubated at 37°C, and 5% carbon dioxide. Cells were initially plated in 25 cm2 vented culture flasks, at a density of 2 × 106 cells/mL. After 3 days, medium and nonadherent cells were discarded.. ...
Cell differentiation in embryogenesis involves extensive changes in gene expression structural reorganization within the nucleus, including chromatin condensation and nucleoprotein immobilization. We hypothesized that nuclei in naive stem cells would therefore prove to be physically plastic and also more pliable than nuclei in differentiated cells. Micromanipulation methods indeed show that nuclei in human embryonic stem cells are highly deformable and stiffen 6-fold through terminal differentiation, and that nuclei in human adult stem cells possess an intermediate stiffness and deform irreversibly. Because the nucleo-skeletal component Lamin A/C is not expressed in either type of stem cell, we knocked down Lamin A/C in human epithelial cells and measured a deformability similar to that of adult hematopoietic stem cells. Rheologically, lamin-deficient states prove to be the most fluidlike, especially within the first ≈10 sec of deformation. Nuclear distortions that persist longer than this are

Boy, these must be difficult times for all those embronic stem cell research advocates. With so many reports coming out showing the potential for adult stem cells, and the Korean cloning scandal to boot, will they join the adult stem cell cause (at least as an additional cause, if not a replacement)?

A research team at Nanyang Technological University, Singapore (NTU Singapore) has found an easier way to harvest healing factors-molecules that promote tissue growth and regeneration-from adult stem cells.. Presently, scientists pre-condition adult stem cells to secrete healing factors by putting them in a low-oxygen chamber or by using biochemicals or genetic engineering.. However in lab experiments, the NTU team of materials scientists and biologists tried mimicking the physical conditions that cells find inside the body and grew a particular type of stem cell-Mesenchymal Stem Cells (MSCs) - on a softer surface than is normally used.. MSCs grown on the softer surface, known as hydrogel, increased their secretion of healing factors, known as the secretome, compared to normal growing surfaces. ...

The four newest approvals are sold by the company BioTime, Inc., which had two other hESC lines approved June 2, 2011. Details of the embryo destruction and hESC derivation (including from siblings) were published by ESI and Sydney IVF workers in 2007, around the time that ESI abandoned its schemes for therapies based on hESC. BioTime subsequenctly acquired ESI in 2010.. The total number of approved hESC lines is now 132, after a push of approvals earlier this year at NIH.. While NIH continues to waste more taxpayer funds on destructive embryo research, adult stem cells are the only stem cell treating patients, with more and more published evidence accumulating every week. Published scientific evidence over the last few months shows effectiveness of adult stem cells in helping patients with angina pain, aggressive multiple sclerosis, enlarged hearts, systemic sclerosis, and creating new windpipes, to name just a few examples of adult stem cell successes.. Adult stem cells remain the gold ...
Biologically there are several reasons adult stem cells are preferable. First they dont require immune suppressive drugs to prevent rejection (not an issue with some transplants, but certainly important for pancreatic tissue and thus diabetes) Second ESC are less developed than adult stem cells and ESCs may errantly develop growing without constraint because the DNA does not have an adult methylation state (sounds like cancer because it is like cancer). This actually happened in one European clinical trial. Adult stem cells are capable of a more limited cell type production and do not appear to have the unconstrained quality of ES cells. Obviously someday someone might figure out how to fix ESCs but how long if ever that would take is unknowable ...

It has also been suggested that BMSCs provide an environment conducive to regeneration in the injured cord. Methods: In the current study, both spinal cord-derived NSPCs and BMSCs were cultured from adult male rats expressing eGFP. Neurospheres or dissociated BMSCs were transplanted 9 days after clip compression injury (35-g force). Cell survival and fate, and functional recovery were examined after 14 weeks. Results: BMSCs showed no neural differentiation but had much ...
For Adult stem cells. Myth: Embryonic stem cell research has the greatest promise. Fact: Up to now, no human being has ever been cured of a disease using embryonic stem cells.

Mesenchymal stem cells (MSCs) have been identified as a viable treatment for inflammatory bowel disease (IBD). MSCs derived from bone marrow (BM-MSCs) have predominated in experimental models whereas the majority of clinical trials have used MSCs derived from adipose tissue (AT-MSCs), thus there is little consensus on the optimal tissue source. The therapeutic efficacies of these MSCs are yet to be compared in context of the underlying dysfunction of the enteric nervous system innervating the gastrointestinal tract concomitant with IBD. This study aims to characterise the in vitro properties of MSCs and compare their in vivo therapeutic potential for the treatment of enteric neuropathy associated with intestinal inflammation. BM-MSCs and AT-MSCs were validated and characterised in vitro. In in vivo experiments, guinea-pigs received either 2,4,6-trinitrobenzene-sulfonate acid (TNBS) for the induction of colitis or sham treatment by enema. MSCs were administered at a dose of 1x106 cells via enema 3 hours

Pope Benedict XVI has reaffirmed his opposition to embryonic stem cell research, saying its morally wrong to destroy an embryo no matter how beneficial the resulting treatment is.. Benedict made the comments Saturday to participants of a Vatican conference on adult stem cells convened under an unusual new partnership between the Vaticans culture office and a small U.S. biotech firm, NeoStem Inc.. Church teaching holds that life begins at conception. As a result, the Vatican opposes embryonic stem cell research because embryos are destroyed in the process. It supports research using adult stem cells.. Benedict said: The destruction of even one human life can never be justified in terms of the benefit that it might conceivably bring to another. ...

AU - Wagner, Kay Uwe. AU - Mohi, Golam. PY - 2014/7. Y1 - 2014/7. N2 - Jak2, a member of the Janus kinase family of nonreceptor protein tyrosine kinases, is activated in response to a variety of cytokines, and functions in survival and proliferation of cells. An activating JAK2V617F mutation has been found in most patients with myeloproliferative neoplasms, and patients treated with Jak2 inhibitors show significant hematopoietic toxicities. However, the role of Jak2 in adult hematopoietic stem cells (HSCs) has not been clearly elucidated. Using a conditional Jak2 knockout allele, we have found that Jak2 deletion results in rapid loss of HSCs/progenitors leading to bone marrow failure and early lethality in adult mice. Jak2 deficiency causes marked impairment in HSC function, and the mutant HSCs are ...
The relevant adult marrow-derived cell populations capable of acquiring the lung phenotype have not been fully identified or characterized. Using parabiotic mice that share a common circulatory system, Abe and colleagues have shown that bone marrow-derived cells are recruited to the lung during elastase-induced emphysema [9]. The accumulating data suggest the existence of circulating stem A cells that we assumed and also raise the possibility of using of adult marrow-derived cells to treat COPD/emphysema [10,11]. Our understanding of the resident progenitor cellular components of the human lung is progressing rapidly, as is our understanding of the dynamic behavior of adult stem/progenitor cells. If future stem-cell-based therapies are to be successful, it is important that we fully understand that the basic regulating mechanism for the dynamic behavior of adult stem/ progenitor cells in the lung is a biosystem. The mathematical model we proposed in this paper is a first trial of establishing ...

A stem cell is a cell that has the ability to duplicate itself endlessly and to become cells of virtually any organ and tissue of the body. Embryonic stem cells are cells extracted from the blastula, the very early embryo, that have an exceptional ability to duplicate in vitro, that is in a test tube, and to become cells of almost any tissue. Adult stem cells are cells found in an organism after birth. Until very recently, it was believed that adult stem cells could only become blood cells, bone and connective tissue. But recent development over the past 5 years have revealed that adult stem cells have capabilities similar to embryonic stem cells.. 2. What is the Stem Cell Theory of Renewal?.

New insights have been added to identification, behavior and cellular properties of embryonic and tissue-specific stem cells over the last few years. in the lung, can help to identify novel targets which will prevent and rescue the fatal lung disease in Rabbit Polyclonal to RPLP2 infancy and childhood and for lung regeneration after injury. Furthermore, identification of the molecular programs regulating the balance between the proliferation and differentiation of endogenous lung-specific stem cells is critical for developing techniques that harness the ability of these cells to regenerate diseased and damaged lungs. Despite its importance, little is known about ACD in epithelial stem cells in the lung. Undifferentiated epithelial stem cells undergo multiple division-linked cell fate decisions (symmetric and asymmetric) in the lung, which lead to an apparently homogeneous expansion of the stem cell populace (Lu et al., 2008; Rawlins, 2008). Multipotent epithelial stem cells localize within the ...

The Pro-Life Secretariat of the U.S. Conference of Catholic Bishops continues to oppose embryonic work. Deirdre McQuade, an official there, said that compared to adult stem cell research, work on embryonic cells is proving fruitless.. Adult cells have been transplanted routinely for decades, first in bone marrow transplants and then in procedures that transfer just the cells. Doctors recover the cells from the marrow or bloodstream of a patient or a donor, and infuse them as part of the treatment for leukemia, lymphoma and other blood diseases. Tens of thousands of people are saved each year by such procedures, experts say.. ...
If the FDA can claim that a persons own stem cells (manipulated, cultured, or not) are drugs and therefore have authority to regulate, then how can any abortions be legal when the same criteria is applied? Think about it. I am taking no position on abortion rights. This is purely an exercise in basic biology and semantics. Once a zygote is produced in the fallopian tube and is then fertilized by sperm, it becomes an embryonic stem cell ready to divide; becoming a fetus. The Supreme Court in Roe V. Wade ruled that a pregnant woman has a right to abort (or manipulate) an unborn fetus (a large collection of embryonic stem cells, at very early stages), because her body is her own property. This being the case, then how is that different than using your own adult stem cells for whatever purpose you like. Morality and political positions aside, the argument in Roe V. Wade is prima facie with regards to autologous adult stem cell manipulation. Therefore, if adult stem cells are classified as drugs and ...

Recently, we have described a simple protocol to obtain an enriched culture of adult stem cells organized in neurospheres from two post-natal tissues: skin and adipose tissue. Due to their possible application in neuronal tissue regeneration, here we tested two kinds of scaffold well known in tissue engineering application: hyaluronan based membranes and fibrin-glue meshes. Neurospheres from skin and adipose tissue were seeded onto two scaffold types: hyaluronan based membrane and fibrin-glue meshes. Neurospheres were then induced to acquire a glial and neuronal-like phenotype. Gene expression, morphological feature and chromosomal imbalance (kariotype) were analyzed and compared. Adipose and skin derived neurospheres are able to grow well and to differentiate into glial/neuron cells without any chromosomal imbalance in both scaffolds. Adult cells are able to express typical cell surface markers such as S100; GFAP; nestin; βIII tubulin; CNPase. In summary, we have demonstrated that neurospheres

A Kansas Senate committee has endorsed an effort to build a center devoted to adult stem cells at The University of Kansas Medical Center.
Autologous stem cells are theorized to have the ability to self-renew, or divide, to replenish dying tissue of specialized cell types. They are considered by some to be our own built-in repair systems that regenerate cells damaged by disease, injury, and every day wear-and-tear. Once stem cells are administered to the body, they appear to respond to inflammatory signals secreted by damage cells. Ultimately, adult stem cells are thought to replenish these damaged cells.. Attempts at stem cell therapy for autism spectrum disorder targets the brain. In autism, areas of brain regulating memory, concentration, attention, speech etc. are damaged.

The Center for Stem Cells and Regenerative Medicine is striving to cure diseases with adult stem cells-before discoveries are made with embryonic stem cells.
Normal adult stem cells are thought to be relatively quiescent, a property that protects them from proliferative exhaustion (2). Because of this property, label-retention studies have been used to identify and characterize tissue-specific stem cells for decades, following the pioneering work by Potten and colleagues in the intestine (3). The existence of label-retaining cells has been proposed to be important for radiation response (3, 4). Label-retention approaches have also been used to identify stem cells in the interfollicular epidermis (5-9) and the hematopoietic system (10-12). In the hematopoietic stem cell (HSC) compartment, some studies have suggested the existence of a slowly cycling stem cell population (9, 10, 12), whereas other investigators have not found label retention in this compartment (11).
