Reduced differentiation potential of primary MyoD-/- myogenic cells derived from adult skeletal muscle. (1/5339)

To gain insight into the regeneration deficit of MyoD-/- muscle, we investigated the growth and differentiation of cultured MyoD-/- myogenic cells. Primary MyoD-/- myogenic cells exhibited a stellate morphology distinct from the compact morphology of wild-type myoblasts, and expressed c-met, a receptor tyrosine kinase expressed in satellite cells. However, MyoD-/- myogenic cells did not express desmin, an intermediate filament protein typically expressed in cultured myoblasts in vitro and myogenic precursor cells in vivo. Northern analysis indicated that proliferating MyoD-/- myogenic cells expressed fourfold higher levels of Myf-5 and sixfold higher levels of PEA3, an ETS-domain transcription factor expressed in newly activated satellite cells. Under conditions that normally induce differentiation, MyoD-/- cells continued to proliferate and with delayed kinetics yielded reduced numbers of predominantly mononuclear myocytes. Northern analysis revealed delayed induction of myogenin, MRF4, and other differentiation-specific markers although p21 was upregulated normally. Expression of M-cadherin mRNA was severely decreased whereas expression of IGF-1 was markedly increased in MyoD-/- myogenic cells. Mixing of lacZ-labeled MyoD-/- cells and wild-type myoblasts revealed a strict autonomy in differentiation potential. Transfection of a MyoD-expression cassette restored cytomorphology and rescued the differentiation deficit. We interpret these data to suggest that MyoD-/- myogenic cells represent an intermediate stage between a quiescent satellite cell and a myogenic precursor cell.  (+info)

Lack of regulation in the heart forming region of avian embryos. (2/5339)

The ability to regenerate a heart after ablation of cardiogenic mesoderm has been demonstrated in early stage fish and amphibian embryos but this type of regulation of the heart field has not been seen in avians or mammals. The regulative potential of the cardiogenic mesoderm was examined in avian embryos and related to the spatial expression of genes implicated in early cardiogenesis. With the identification of early cardiac regulators such as bmp-2 and nkx-2.5, it is now possible to reconcile classical embryological studies with molecular mechanisms of cardiac lineage determination in vivo. The most anterior lateral embryonic cells were identified as the region that becomes the heart and removal of all or any subset of these cells resulted in the loss of corresponding cardiac structures. In addition, removal of the lateral heart forming mesoderm while leaving the lateral endoderm intact also results in loss of cardiac structures. Thus the medial anterior mesoderm cannot be recruited into the heart lineage in vivo even in the presence of potentially cardiac inducing endoderm. In situ analysis demonstrated that genes involved in early events of cardiogenesis such as bone morphogenetic protein 2 (bmp-2) and nkx-2.5 are expressed coincidentally with the mapped far lateral heart forming region. The activin type IIa receptor (actR-IIa) is a potential mediator of BMP signaling since it is expressed throughout the anterior mesoderm with the highest level of expression occurring in the lateral prospective heart cells. The posterior boundary of actR-IIa is consistent with the posterior boundary of nkx-2.5 expression, supporting a model whereby ActR-IIa is involved in restricting the heart forming region to an anterior subset of lateral cells exposed to BMP-2. Analysis of the cardiogenic potential of the lateral plate mesoderm posterior to nkx-2.5 and actR-IIa expression demonstrated that these cells are not cardiogenic in vitro and that removal of these cells from the embryo does not result in loss of heart tissue in vivo. Thus, the region of the avian embryo that will become the heart is defined medially, laterally, and posteriorly by nkx-2.5 gene expression. Removal of all or part of the nkx-2.5 expressing region results in the loss of corresponding heart structures, demonstrating the inability of the chick embryo to regenerate cardiac tissue in vivo at stages after nkx-2.5 expression is initiated.  (+info)

Expression and developmental regulation of the Hydra-RFamide and Hydra-LWamide preprohormone genes in Hydra: evidence for transient phases of head formation. (3/5339)

Hydra magnipapillata has three distinct genes coding for preprohormones A, B, and C, each yielding a characteristic set of Hydra-RFamide (Arg-Phe-NH2) neuropeptides, and a fourth gene coding for a preprohormone that yields various Hydra-LWamide (Leu-Trp-NH2) neuropeptides. Using a whole-mount double-labeling in situ hybridization technique, we found that each of the four genes is specifically expressed in a different subset of neurons in the ectoderm of adult Hydra. The preprohormone A gene is expressed in neurons of the tentacles, hypostome (a region between tentacles and mouth opening), upper gastric region, and peduncle (an area just above the foot). The preprohormone B gene is exclusively expressed in neurons of the hypostome, whereas the preprohormone C gene is exclusively expressed in neurons of the tentacles. The Hydra-LWamide preprohormone gene is expressed in neurons located in all parts of Hydra with maxima in tentacles, hypostome, and basal disk (foot). Studies on animals regenerating a head showed that the prepro-Hydra-LWamide gene is expressed first, followed by the preprohormone A and subsequently the preprohormone C and the preprohormone B genes. This sequence of events could be explained by a model based on positional values in a morphogen gradient. Our head-regeneration experiments also give support for transient phases of head formation: first tentacle-specific preprohormone C neurons (frequently associated with a small tentacle bud) appear at the center of the regenerating tip, which they are then replaced by hypostome-specific preprohormone B neurons. Thus, the regenerating tip first attains a tentacle-like appearance and only later this tip develops into a hypostome. In a developing bud of Hydra, tentacle-specific preprohormone C neurons and hypostome-specific preprohormone B neurons appear about simultaneously in their correct positions, but during a later phase of head development, additional tentacle-specific preprohormone C neurons appear as a ring at the center of the hypostome and then disappear again. Nerve-free Hydra consisting of only epithelial cells do not express the preprohormone A, B, or C or the LWamide preprohormone genes. These animals, however, have a normal phenotype, showing that the preprohormone A, B, and C and the LWamide genes are not essential for the basic pattern formation of Hydra.  (+info)

Immunocytochemical and morphological evidence for intracellular self-repair as an important contributor to mammalian hair cell recovery. (4/5339)

Although recent studies have provided evidence for hair cell regeneration in mammalian inner ears, the mechanism underlying this regenerative process is still under debate. Here we report immunocytochemical, histological, electron microscopic, and autoradiographic evidence that, in cultured postnatal rat utricles, a substantial number of hair cells can survive gentamicin insult even their stereocilia are lost. These partially damaged hair cells can survive for a prolonged time and regrow the stereocilia. Although the number of stereocilia-bearing hair cells increases over time after gentamicin insult, hair cell and supporting cell numbers remain essentially unchanged. Tritiated thymidine autoradiography and bromodeoxyuridine immunocytochemistry of the cultures demonstrate that cell proliferation in the sensory epithelium is very limited and is far below the number of recovered hair cells. Furthermore, terminal deoxynucleotidyl transferase-mediated biotinylated UTP nick end labeling analysis indicates that gentamicin-induced apoptosis in the sensory epithelium occurs mainly during a 2 d treatment period, and additional cell death is minimal 2-11 d after treatment. Considered together, intracellular repair of partially damaged hair cells can be an important contributor to spontaneous hair cell recovery in mammalian inner ears.  (+info)

Alteration of endothelium-dependent hyperpolarizations in porcine coronary arteries with regenerated endothelium. (5/5339)

The present study was designed to test the ability of regenerated endothelium to evoke endothelium-dependent hyperpolarizations. Hyperpolarizations induced by serotonin and bradykinin were compared in isolated porcine coronary arteries with native or regenerated endothelium, 4 weeks after balloon endothelial denudation. The experiments were performed in the presence of inhibitors of nitric oxide synthase (Nomega-nitro-L-arginine) and cyclooxygenase (indomethacin). The transmembrane potential was measured using conventional glass microelectrodes. Smooth muscle cells from coronary arteries with regenerated endothelium were depolarized in comparison with control coronary arteries from the same hearts. Spontaneous membrane potential oscillations of small amplitude or spikes were observed in some of these arteries but never in arteries with native endothelium. In coronary arteries from control pigs, both serotonin and bradykinin induced concentration-dependent hyperpolarizations. In the presence of ketanserin, 10 micromol/L serotonin induced a transient hyperpolarization in control coronary arteries. Four weeks after balloon denudation, the response to serotonin was normal in arteries with native endothelium, but the hyperpolarization was significantly lower in coronary arteries with regenerated endothelium. In control arteries, the endothelium-dependent hyperpolarization obtained with bradykinin (30 nmol/L) was reproducible. Four weeks after balloon denudation, comparable hyperpolarizations were obtained in coronary arteries with native endothelium. By contrast, in arteries with regenerated endothelium, the hyperpolarization to bradykinin became voltage-dependent. In the most depolarized cells, the hyperpolarization to bradykinin was augmented. The changes in resting membrane potential and the alteration in endothelium-dependent hyperpolarizations observed in the coronary arteries with regenerated endothelium may contribute to the reduced response to serotonin and the unchanged relaxation to bradykinin described previously.  (+info)

The homeodomain protein IDX-1 increases after an early burst of proliferation during pancreatic regeneration. (6/5339)

Islet duodenal homeobox 1 (IDX-1/PF-1/STF-1/PDX-1), a homeodomain protein that transactivates the insulin promoter, has been shown by targeted gene ablation to be required for pancreatic development. After 90% pancreatectomy (Px), the adult pancreas regenerates in a process recapitulating embryonic development, starting with a burst of proliferation in the epithelium of the common pancreatic duct. In this model, IDX-1 mRNA was detected by semiquantitative reverse transcription-polymerase chain reaction in total RNA from isolated common pancreatic ducts at levels 10% of those of isolated islets. The IDX-1 mRNA levels were not significantly different for common pancreatic ducts of Px, sham Px, and unoperated rats and did not change with time after surgery. By immunoblot analysis, IDX-1 protein was only faintly detected in these ducts 1 and 7 days after Px or sham Px but was easily detected at 2 and 3 days after Px. Similarly, IDX-1 immunostaining was barely detectable in sham or unoperated ducts but was strong in ducts at 2-3 days after Px. The increase of IDX-1 immunostaining followed that of BrdU incorporation (proliferation). These results indicate a posttranscriptional regulation of the IDX-1 expression in ducts. In addition, islets isolated 3-7 d after Px showed higher IDX-1 protein expression than control islets. Thus, in pancreatic regeneration IDX-1 is upregulated in newly divided ductal cells as well as in islets. The timing of enhanced expression of IDX-1 implies that IDX-1 is not important in the initiation of regeneration but may be involved in the differentiation of ductal cells to beta-cells.  (+info)

Hedgehog is required for activation of engrailed during regeneration of fragmented Drosophila imaginal discs. (7/5339)

Surgically fragmented Drosophila appendage primordia (imaginal discs) engage in wound healing and pattern regulation during short periods of in vivo culture. Prothoracic leg disc fragments possess exceptional regulative capacity, highlighted by the ability of anterior cells to convert to posterior identity and establish a novel posterior compartment. This anterior/posterior conversion violates developmental lineage restrictions essential for normal growth and patterning of the disc, and thus provides an ideal model for understanding how cells change fate during epimorphic pattern regulation. Here we present evidence that the secreted signal encoded by hedgehog directs anterior/posterior conversion by activating the posterior-specific transcription factor engrailed in regulating anterior cells. In the absence of hedgehog activity, prothoracic leg disc fragments fail to undergo anterior/posterior conversion, but can still regenerate missing anterior pattern elements. We suggest that hedgehog-independent regeneration within the anterior compartment (termed integration) is mediated by the positional cues encoded by wingless and decapentaplegic. Taken together, our results provide a novel mechanistic interpretation of imaginal disc pattern regulation and permit speculation that similar mechanisms could govern appendage regeneration in other organisms.  (+info)

Transforming growth factor-beta-induced upregulation of transforming growth factor-beta receptor expression in pancreatic regeneration. (8/5339)

The transforming growth factor-beta (TGFbeta) signaling pathway is one important player in the regulation of extracellular matrix turnover and cell proliferation in epithelial regeneration. We used cerulein-induced pancreatitis in rats as a model to investigate the regulation of TGFbeta receptor type I and type II expression on protein and messenger RNA level during regeneration. In the regenerating pancreas, mRNA levels of TGFbeta receptor I and II were significantly increased with a maximum after 2 days. On protein level, expression of TGFbeta receptor II was significantly increased after three to 3-5 days. This elevated expression could be inhibited by neutralizing the endogenous biological activity of TGFbeta1 with a specific antibody. In cultured pancreatic epithelial cells, TGFbeta1 reduced cell proliferation as measured by [3H]thymidine incorporation. Furthermore the transcript levels of TGFbeta1 as well as mRNA and protein concentrations of type I and type II receptor increased during TGFbeta stimulation in vitro. These results indicate that epithelial pancreatic cells contribute to the enhanced TGFbeta1 synthesis during pancreatic regeneration by an autocrine mechanism. TGFbeta1, furthermore, upregulates the expression of its own receptors during the regenerative process, thereby contributing to the increase of the TGFbeta-induced cellular responses.  (+info)

Title:Adult Stem Cells and Skeletal Muscle Regeneration. VOLUME: 15 ISSUE: 4. Author(s):Domiziana Costamagna, Emanuele Berardi, Gabriele Ceccarelli and Maurilio Sampaolesi. Affiliation:Translational Cardiomyology Laboratory, Stem Cell Institute Leuven, KU Leuven, Belgium.. Keywords:Adult stem cells, Muscular dystrophy, Skeletal muscle regeneration.. Abstract:Satellite cells are unipotent stem cells involved in muscle regeneration. However, the skeletal muscle microenvironment exerts a dominant influence over stem cell function. The cell intrinsic complexity of the skeletal muscle niche located within the connective tissue between fibers includes motor neurons, tendons, blood vessels, immune response mediators and interstitial cells. All these cell types modulate the trafficking of stimuli responsible of muscle fiber regeneration. In addition, several stem cell types have been discovered in skeletal muscle tissue, mainly located in the interstitium. The majority of these stem cells appears to ...

AU - Izpisua Belmonte, Juan Carlos. PY - 2012/4/3. Y1 - 2012/4/3. N2 - Background: Mammals are not able to restore lost appendages, while many amphibians are. One important question about epimorphic regeneration is related to the origin of the new tissues and whether they come from mature cells via dedifferentiation and/or from stem cells. Several studies in urodele amphibians (salamanders) indicate that, after limb or tail amputation, the multinucleated muscle fibres do dedifferentiate by fragmentation and proliferation, thereby contributing to the regenerate. In Xenopus laevis tadpoles, however, it was shown that muscle fibres do not contribute directly to the tail regenerate. We set out to study whether dedifferentiation was present during muscle regeneration of the tadpole limb and zebrafish larval tail, mainly by cell ...
Apparatuses, systems, and methods for enhancing bone or soft tissue regeneration are provided. For example, a conduit, having one or more segments, can originate at a tissue regeneration site and can have a first opening to promote physiological signals to enter the conduit and transit to a second opening that penetrates a histologically rich source of multipotent mesenchymal cells, promoting the multipotent mesenchymal cells to produce tissue regeneration response products, the response products transiting through the second opening to egress at the first opening of the conduit, and promoting tissue regeneration at the tissue regeneration site. Transit of the physiological signals and the tissue regeneration response products is promoted through physical and/or chemical means, as is promotion of the anatomical functionality of the regenerated tissue. For example, a number of the segments of the conduit can be formed at least partially from an osteoceramic material.

Here, we used classical genetics in zebrafish to identify temperature-sensitive mutants in caudal fin regeneration. Gross morphological, histological, and molecular analyses revealed that one of these strains, emmental (emm), failed to form a functional regeneration blastema. Inhibition of emm function by heat treatment during regenerative outgrowth rapidly blocked regeneration. This block was associated with reduced proliferation in the proximal blastema and expansion of the nonproliferative distal blastemal zone. Positional cloning revealed that the emm phenotype is caused by a mutation in the orthologue of yeast sly1, a gene product involved in protein trafficking. sly1 is upregulated in the newly formed blastema as well as during regenerative outgrowth. Thus, sly1 is essential for blastemal organization and proliferation during two stages of fin regeneration ...

In the adult heart, the immune system facilitates scar formation, which repairs the damaged myocardium but compromises cardiac function. In neonatal mice, the heart can regenerate fully without scarring following MI; however, this regenerative capacity is lost by P7. The signals that govern neonatal heart regeneration are unknown. By comparing the immune response to MI in mice at P1 and P14, we identified differences in the magnitude and kinetics of monocyte and macrophage responses to injury. Using a cell-depletion model, we determined that heart regeneration and ...

Regeneration research is more focused on translational values. However, lying at its very foundation is an understanding of how tissues and organs repair and renew themselves at the cellular level. The past decade has witnessed paradigm changing advances in regenerative biology, many of these stems from novel insights into stemness, pluripotency, cell death and their related intra- and inter-cellular biochemical and molecular processes. Some of these new insights are highlighted in the paragraphs that follow. We now have a much better understanding of how regeneration occurs in lower organisms. We have also discovered tools and means of nuclear reprogramming to generate induced pluripotency and changes in cell fate in mammalian models. With further research, there is reasonable hope that various obstacles of regeneration in humans can be better understood and tackled. As regeneration research enters a new era, CellBio welcomes timely review articles and original papers on the theme of

This work studies Ni-based catalyst deactivation and regeneration processes in the presence of H2S under a biogas tri-reforming process for hydrogen production, which is an energy vector of great interest. 25 ppm of hydrogen sulfide were continuously added to the system in order to provoke an observable catalyst deactivation, and once fully deactivated two different regeneration processes were studied: a self-regeneration and a regeneration by low temperature oxidation. For that purpose, several Ni-based catalysts and a bimetallic Rh-Ni catalyst supported on alumina modified with CeO2 and ZrO2 were used as well as a commercial Katalco 57-5 for comparison purposes. Ni/Ce-Al2O3 and Ni/Ce-Zr-Al2O3 catalysts almost recovered their initial activity. For these catalysts, after the regeneration under oxidative conditions at low temperature, the CO2 conversions achieved-79.5% and 86.9%, respectively-were significantly higher than the ones obtained before sulfur poisoning-66.7% and 45.2%, respectively.

Background: Epidemiological studies related poor maternal nutrition and subsequent growth retardation in the progeny to the development of diabetes later in life. Low-protein diet during gestation altered the beta-cell development of the rat progeny by decreasing beta-cell proliferation and increasing their sensitivity to nitric oxide and cytokines in the foetus. This disturbed maternal environment had long-lasting consequences because the higher beta-cell vulnerability was maintained at adulthood. Aim: The aim of this study was to determine whether early malnutrition influences the vulnerability and the regeneration capacity of beta-cells after streptozotocin (STZ) damage at adulthood. Methods: Gestating rats were fed either a control or a low-protein diet until weaning. Adult female offspring received injections of Freunds adjuvant weekly for 5 weeks followed 24 h later by STZ. Half of the cohort was killed at d34, whereas the other half was maintained until d48 to analyse the regeneration ...
The pancreas is a vertebrate-specific endodermal organ executing major functions in food digestion and glucose homeostasis. The mature organ is composed of an exocrine compartment with acinar and duct cells that produce and transport digestive enzymes into the gut, and an endocrine compartment from which metabolism-regulating peptide hormones including insulin are secreted into the blood stream. Studies on pancreas regeneration have focused mainly on the endocrine compartment, with the aim of gaining knowledge on β-cell regeneration. More recently, exocrine pancreas regeneration has been receiving more attention in the context of cancer and diabetes research because experimental models revealed a high capacity for cell fate plasticity (Murtaugh and Keefe, 2015).. Regeneration of exocrine tissue has been mainly studied in mouse models, where the loss of cells can be induced by caerulein treatment or partial duct ligation (Aghdassi et al., 2011; Lerch and Gorelick, 2013). Using these procedures, ...

In humans, most cardiovascular disorders lead to the destruction of cardiac tissue which will be replaced by fibrosis, leading to arrhythmia and reduced contractile function, resulting in an increase in ventricular load. In order to maintain an overall cardiac output, cardiomyocytes undergo hypertrophic response, leading to pathological hypertrophy and heart failure. This increase in ventricular load, have to be sensed by mechanosensors such as the mechanosensitive ion channels such as TREK-1. Unlike mammals, adult zebrafish (zf) can fully regenerate their heart after an extensive insult through cardiomyocyte dedifferentiation followed by proliferation. We believe that in adult mammals, cardiomyocyte proliferation has been blocked/inhibited. Therefore its likely that genes which respond to increased ventricular load in mammals and trigger pathological hypertrophy will trigger cardiomyocyte proliferation during heart regeneration in zf. In this study we show that zTREK1a and zTREK1b have similar

Towards Minimally Invasive Exosome Therapies for Internal Organ Regeneration - posted in News: Targeted delivery of therapeutics remains one of the thorny issues in medical development. Everyone wants a way to deliver high doses of a therapeutic to a specific location in the body without it also ending up everywhere else. The major issue is that systemic administration will send the majority of whatever is injected into the body into the liver and lungs, and that limits the dose that can b...
Researchers at Weill Cornell Medical College, and colleagues, say they have taken an important step forward in their quest to turn on lung regeneration -- an advance that could effectively treat millions of people suffering from respiratory disorders. In the October 28, 2011 issue of Cell, the research team reports that they have uncovered the biochemical signals in mice that trigger generation of new lung alveoli, the numerous, tiny, grape-like sacs within the lung where oxygen exchange takes place. Specifically, the regenerative signals originate from the specialized endothelial cells that line the interior of blood vessels in the lung. While it has long been known that mice can regenerate and expand the capacity of one lung if the other is missing, this study now identifies molecular triggers behind this process, and the researchers believe these findings are relevant to humans. Several adult human organs have the potential upon injury to regenerate to a degree, and while we can readily ...
Macrophages play an essential role in the resolution of tissue damage through removal of necrotic cells, thus paving the way for tissue regeneration. Macrophages also directly support the formation of new tissue to replace the injury, through their acquisition of an anti-inflammatory, or M2, phenotype, characterized by a gene expression program that includes IL-10, the IL-13 receptor, and arginase 1. We report that deletion of two CREB-binding sites from the Cebpb promoter abrogates Cebpb induction upon macrophage activation. This blocks the downstream induction of M2-specific Msr1, Il10, II13ra, and Arg-1 genes, whereas the inflammatory (M1) genes Il1, Il6, Tnfa, and Il12 are not affected. Mice carrying the mutated Cebpb promoter (betaDeltaCre) remove necrotic tissue from injured muscle, but exhibit severe defects in muscle fiber regeneration. Conditional deletion of the Cebpb gene in muscle cells does not affect regeneration, showing that the C/EBPbeta cascade leading to muscle repair is muscle

A mammal model of true organ regeneration may help scientists better understand this process so that they can prompt the regeneration of human organs.
An abundance of data across several vertebrate taxon groups (3, 11, 12) suggests that nerves may have a conserved evolutionary role that is essential to, or permissive for, limb regeneration. Despite the absence of innervation to the hind limb throughout the time of regeneration, the mouse model replaces the amputated digit tip with surprising fidelity in most tissue types. Our comprehensive examination at single-cell levels of primary hind limb tissues during normal maintenance, regeneration, and wound healing reveals that many presumed tissue stem/progenitor cells maintain clonal and differentiation capabilities in the absence of nerve supply.. In salamander embryos, removal of a large section of the neural tube leads to limb development without innervation. These limbs can be transplanted to the flank of a normal larva, where they can regenerate in the absence of nerve supply (33). This lack of nerve dependence is made possible by the substitution of nerve-derived factors from ectodermal ...

New research in mice and rats, conducted at Wake Forest Baptist Medical Centers Institute for Regenerative Medicine, suggests that in body regeneration of muscle tissue might be possible by harnessing the bodys natural healing powers.. Reporting online ahead of print in the journal Acta Biomaterialia, the research team demonstrated the ability to recruit stem cells that can form muscle tissue to a small piece of biomaterial, or scaffold that had been implanted in the animals leg muscle. The secret to success was using proteins involved in cell communication and muscle formation to mobilize the cells.. Working to leverage the bodys own regenerative properties, we designed a muscle-specific scaffolding system that can actively participate in functional tissue regeneration, said Sang Jin Lee, Ph.D., assistant professor of regenerative medicine and senior author. This is a proof-of-concept study that we hope can one day be applied to human patients. ...
The mammalian heart has generally been considered to lack the ability to repair itself after injury, but a 2011 study in new-born mice challenged this view, providing evidence for complete regeneration after resection of 10% of the apex. However, in this study researchers attempted to replicate these recent findings but failed to uncover any evidence of complete heart regeneration in new-born mice that underwent apex resection.
In response to a severe injury that destroys a majority of the tissue, skeletal muscle is capable of complete regeneration and restoration of the cytoarchitecture within a 2‐week period (Miller et al, 1999; Seale and Rudnicki 2000; Shi and Garry 2006). This remarkable regenerative capacity is due to a rare population of cells termed myogenic progenitor cells that are resident in adult skeletal muscle. Although intense interest has been directed toward muscle regeneration, the molecular mechanisms that direct the MPC population are incompletely defined. In the present study, we have begun to decipher the MPC regulatory program by making three principal findings that enhance our mechanistic understanding of the MPC population. First, we utilized transgenic technology to define modular sequences of the Foxk1 gene that directs lacZ reporter expression to the MPC population. We have previously demonstrated that Foxk1 is restricted to the MPC population in adult skeletal muscle (Garry et al, 1997, ...
Before the new study, scientists did not know if all cardiomyocytes in the zebrafish heart shared the same regenerative ability or if they were equally able to regenerate all zones of the heart muscle. Cell plasticity, the ability of cells to convert themselves into another cell type, is frequently observed during embryonic development, but has never before been reported during tissue regeneration in an adult organism. In the study, which received funding from the European Research Council (ERC Starting Grant 2013 337703 zebraHeart), the authors investigated two types of cardiomyocyte, one localized in the innermost heart regions, the trabeculae, and the other in the exterior heart wall. Scientists had presumed that during regeneration each cardiomyoctye population would give rise only to the same specialized cell type. But the CNIC study shows that cardiomyocytes from the trabeculae can contribute to the regeneration of the external heart wall. The researchers conclude that their results ...
Direct regenerations by using mature cotyledonary node as a explants has been shown to be time-saving and convenient strategy for micropropagation of soybean. So we have evaluated regeneration protocol through single shoot using cotyledonary node as a rapid and efficient protocol for two soybean cultivars and one mutant line. Cotyledonary nodes explants obtained from 7-days-old in vitro seedlings. After 28 days, the percent of regeneration and after 42 days, regeneration area were calculated. The results showed that percent of regeneration and regeneration area of mutant line was significantly more than two cultivars, L17 and Williams. After shoot induction, plants were transferred to shoot elongation medium followed by transferring plants to rooting medium. The results showed that the percent of rooting was not significantly affected by genotypes. In another experiment to test kanamycin sensitivity of regenerated shoots, it was found that kanamaycin with 150 mg/L concentration is lethal for
In an earlier post, I pointed out the problems with trying to do away with the term regeneration by attempting to subsume regeneration under the category of effectual calling. But while I agree regeneration is a distinct (note: not separate) act from effectual calling, I agreed that it was through Gods Word in effectual calling that regeneration happens.. In his article on the topic however, John Murray goes further, trying to distinguish between two types of regeneration. The first is unmediated by the proclaimed Word but purely of divine fiat. The second is mediated by the proclaimed Word (pp. 196-7). In a certain sense, we can say that some people seem to show signs of regeneration prior to the proclamation of the Gospel, but is that a real example of someone who is regenerated by divine fiat alone apart from the proclaimed Word?. It is my contention that Murray is wrong here. While certainly there is a distinction between the divine fiat Word, and the proclaimed Word, yet, inasmuch as the ...
Regeneration is the ability to restore lost or damaged tissues, organs or limbs. It is a common feature in invertebrates, but far more limited in most vertebrates. Nevertheless, even humans possess some degree of regeneration ability. Children under 6 years of age are capable of regenerating lost fingertips and the human liver retains its ability to regenerate throughout a persons lifetime. Aside from being used to generally describe any number of specific healing processes, regeneration also is a specific method of healing that is noted for its ability to regrow lost limbs, severed nerve connections, and other wounds. This is present in some animals such as the newt, hydra, and a type of mouse. [1] [2]. With the exception of the MRL mice, mammals do not in general have the ability to regenerate. If the processes behind regeneration are fully understood, it is believed this would lead to better treatment for individuals with nerve injuries, broken backs, paralysis, and missing limbs ...
Researchers from Boston Childrens Hospital have discovered that the Lin28 gene, which is linked to Wilms tumor, may be the key to kidney regeneration.
To investigate losartans role in muscle injury regeneration in the context of aging, the Hopkins team worked with 40 mice which, at 21-months old, were considered geriatric. The researchers examined the stained muscle tissue under a microscope at four days and again at 19 days, looking for signs of regeneration: small fibers with larger-than-usual nuclei.. After four days, they saw no difference in the number of regenerating fibers between the losartan-treated mice and those not treated. However, after 19 days, the losartan-treated mice had about 10 to 15 per cent of scar tissue formation compared with 30 to 40 per cent of scar tissue formation in those not treated.. Next, the researchers conducted disuse experiments to find out if losartan, in addition to improving muscle regeneration, might have even broader clinical applications in the protection against immobilization atrophy.. Again, using 21-month-old mice, half treated with losartan and half not, the team this time clipped the hind right ...
Most metazoans have at least some ability to regenerate damaged cells and tissues, although the regenerative capacity varies depending on the species, organ, or developmental stage. Cell replacement and regeneration occur in two contexts: renewal of spent cells during tissue homeostasis (homeostatic growth), and in response to external injury, wounding, or amputation (epimorphic regeneration). Model organisms that display remarkable regenerative capacity include amphibians, planarians, Hydra, and the vertebrate liver. In addition, several mammalian organs, including the skin, gut, kidney, muscle, and even the human nervous system, have some ability to replace spent or damaged cells. Although the regenerative response is complex, it typically involves the induction of new cell proliferation through formation of a blastema, followed by cell specification, differentiation, and patterning. Stem cells and undifferentiated progenitor cells play an important role in both tissue homeostasis and tissue ...
Using single-cell RNA sequencing, researchers identified cells in mouse and human prostate tissues that appear to help regrow the gland after prostate cancer treatment.
After myocardial infarction in the mammalian heart, millions of cardiomyocytes are lost and replaced by fibrotic scar tissue. While fibrosis is persistent in adult mammals, there are some vertebrates, including zebrafish, with the capacity for regeneration. This process does not occur in the absence of fibrosis. Here we studied subpopulations of collagen-producing cells and analyzed their fate after complete regeneration of the zebrafish myocardium. Our data show that fibroblasts persisted in the regenerated heart but shut down the profibrotic program. While fibrosis could be considered as detrimental to the regeneration process, our study reveals a positive effect on cardiomyocyte proliferation. Accordingly, a fibrotic response can be beneficial for heart regeneration. In the zebrafish (Danio rerio), regeneration and fibrosis after cardiac injury are not mutually exclusive responses. Upon cardiac cryoinjury, collagen and other extracellular matrix (ECM) proteins accumulate at the injury site. However,
ECM remodeling is a critical step in development, wound healing and regeneration (31, 38, 40, 41, 60). The present study characterized the ECM composition and its changes during zebrafish regeneration. We have developed a decellularization protocol for zebrafish ventricles that results in ECM enrichment, as well as facilitating the analysis of the proteomic profile of the zebrafish ventricle ECM. Moreover, we have analyzed the ECM changes during heart regeneration and assessed the stiffness of the ECM at different time points of this process. Altogether, the results from our studies should help better understanding the role of the ECM in zebrafish heart regeneration.. The ECM composition has not been fully studied and described in the specific contexts of the zebrafish heart and cardiac regeneration. Few are the studies done to analyze the ECM in the zebrafish heart. The proteome of different zebrafish organs, including the heart, were analyzed by Abramsson and colleagues and only 4 collagen ...
Fibroblast growth factors (Fgfs) regulate critical biological processes such as embryonic development, tissue homeostais, wound healing, and tissue regeneration. In zebrafish, Fgf signaling plays an important role in the regeneration of the spinal cord, liver, heart, fin, and photoreceptors, although its exact mechanism of action is not fully understood. Utilizing an adult zebrafish extraocular muscle (EOM) regeneration model, we demonstrate that blocking Fgf receptor function using either a chemical inhibitor (SU5402) or a dominant-negative transgenic construct (dnFGFR1a:EGFP) impairs muscle regeneration. Adult zebrafish EOMs regenerate through a myocyte dedifferentiation process, which involves a muscle-to-mesenchyme transition and cell cycle reentry by differentiated myocytes. Blocking Fgf signaling reduced cell proliferation and active caspase 3 levels in the regenerating muscle with no detectable levels of apoptosis, supporting the hypothesis that Fgf signaling is involved in the early ...

2. On the 17th December 2012, I reported to Cabinet the release of the consultation document Vibrant and Viable Places - A New Regeneration Framework. That report also recommended a response to that consultation (Cabinet Minute C1949 refers). 3. That report sets the context for current and future Welsh Government area based programmes with regeneration implications and that context is not repeated here. However, particularly relevant is the fact that the Barry Regeneration Area programme was launched by the Welsh Government in March 2010. A total of £9.8m of Welsh Government investment was allocated to the programme, which was initially intended to run for three years (April 2010 - March 2013 inclusive). However, following the spending review by the United Kingdom Government, this allocation was re-profiled over four years. Cabinet considered an update report on the Barry Regeneration Area Programme and the Welsh Governments Ministerial review of approaches to regeneration on 23rd July 2012 ...
During embryonic development, axons extend over long distances to establish functional connections. In contrast, axon regeneration in the adult mammalian central nervous system (CNS) is limited, in part by a reduced intrinsic capacity for axon growth. Therefore, insight into the intrinsic control of axon growth may provide new avenues for enhancing CNS regeneration. Here, we performed one of the first miRNome-wide functional miRNA screens to identify microRNAs (miRNAs) with robust effects on axon growth. High-content screening identified miR-135a and miR-135b as potent stimulators of axon growth and cortical neuron migration in vitro and in vivo in male and female mice. Intriguingly, both these developmental effects of miR-135s relied, in part, on silencing of KLF4, a well-known intrinsic inhibitor of axon growth and regeneration. These results prompted us to test the effect of miR-135s on axon regeneration following injury. Our study shows that intravitreal application of miR-135s facilitates ...
