Abstract
Thromboangitis obliterans (TAO) is considered to be an inflammatory disease. Previous research has demonstrated that phosphatidylcholine-specific phospholipase C (PC-PLC) plays critical roles in various inflammatory responses. However, the connection between PC-PLC and TAO is undetermined. Therefore, we sought to investigate whether PC-PLC was implicated in TAO. In our study, there were two groups: TAO group and control group. The PC-PLC activity of serum of two groups (16 TAO patients and 11 controls) was detected by PC-PLC activity assay. The level and distribution of PC-PLC in posterior tibial arteries in seven TAO patients and four controls were detected by immunofluorescence staining method. PC-PLC activity increased greatly in serum of TAO patients. Immunofluorescence analysis also revealed an upregulation of PC-PLC in the vascular endothelium of TAO patients. Our data suggest that PC-PLC activity and level increase obviously in TAO patients. Our study may provide new clues for seeking pathogenesis of TAO. Furthermore, it may bring new insights into clinical diagnosis and treatment of TAO.

Abstract
Mesenchymal stem cells (MSC) are multipotent cells found as part of the stromal compartment of the bone marrow and in many other organs. They can be identified in vitro as CFU-F (colony forming unit-fibroblast) based on their ability to form adherent colonies of fibroblast-like cells in culture. MSC expanded in vitro retain characteristics appropriate to their tissue of origin. This is reflected in their propensity for differentiating towards specific lineages, and their capacity to generate, upon retransplantation in vivo, a stroma supporting typical lineages of hematopoietic cells. Hox genes encode master regulators of regional specification and organ development in the embryo and are widely expressed in the adult. We investigated whether they could be involved in determining tissue-specific properties of MSC. Hox gene expression profiles of individual CFU-F colonies derived from various organs and anatomical locations were generated, and the relatedness between these profiles was determined using hierarchical cluster analysis. This revealed that CFU-F have characteristic Hox expression signatures that are heterogeneous but highly specific for their anatomical origin. The topographic specificity of these Hox codes is maintained during differentiation, suggesting that they are an intrinsic property of MSC. Analysis of Hox codes of CFU-F from vertebral bone marrow suggests that MSC originate over a large part of the anterioposterior axis, but may not originate from prevertebral mesenchyme. These data are consistent with a role for Hox proteins in specifying cellular identity of MSC.

Abstract
At the embryonic or fetal stages, autonomously myogenic cells (AMCs), i.e., cells able to spontaneously differentiate into skeletal myotubes, have been identified from several different sites other than skeletal muscle, including the vascular compartment. However, in the adult animal, AMCs from skeletal muscle-devoid tissues have been described in only two cases. One is represented by thymic myoid cells, a restricted population of committed myogenic progenitors of unknown derivation present in the thymic medulla; the other is represented by a small subset of adipose tissue-associated cells, which we recently identified. In the present study we report, for the first time, the presence of spontaneously differentiating myogenic precursors in the pancreas and in other skeletal muscle-devoid organs such as spleen and stomach, as well as in the periaortic tissue of adult mice. Immunomagnetic selection procedures indicate that AMCs derive from Flk-1(+) progenitors. Individual clones of myogenic cells from nonmuscle organs are morphologically and functionally indistinguishable from skeletal muscle-derived primary myoblasts. Moreover, they can be induced to proliferate in vitro and are able to participate in muscle regeneration in vivo. Thus, we provide evidence that fully competent myogenic progenitors can be derived from the Flk-1(+) compartment of several adult tissues that are embryologically unrelated to skeletal muscle.

Abstract
Satellite cells are recognized as the main source for myoblasts in postnatal muscle. The possible participation of other cell types in myofiber maintenance remains a subject of debate. Here, we investigated the potential of vascular preparations from mouse retina to undergo myogenesis when cultured alone or with differentiated primary myogenic cultures. The choice of retina, an organ richly supplied with capillary network and anatomically separated from skeletal muscles, ensures that the vasculature preparation is devoid of satellite cells. We demonstrate that retina-derived cells spontaneously fuse with preexisting myotubes and contribute additional myonuclei, some of which initiate expression of muscle-specific genes after fusion. Myogenic differentiation of retinal cells prior to their fusion with preexisting myotubes was not detected. Although originating from vasculature preparations, nuclei undergoing myogenic reprogramming were contributed by cells that were neither endothelial nor blood borne. Our results suggest smooth muscle/pericytes as the possible source, and that myogenic reprogramming depends on the muscle specific transcription factor MyoD. Our studies provide insights into a novel avenue for myofiber maintenance, relying on nuclei of non-myogenic origin that undergo fusion and subsequent myogenic conversion within host myofibers. This process may support ongoing myofiber maintenance throughout life.

Abstract
Human embryonic stem cells (hESCs) are a promising source for cell therapy in degenerative diseases. A key step in establishing the medical potential of hESCs is the development of techniques for the conversion of hESCs into tissue-restricted precursors suitable for transplantation. We recently described the derivation of multipotent mesenchymal precursors from hESCs. Nevertheless, our previous study was limited by the requirement for mouse feeders and the lack of in vivo data. Here we report a stroma-free induction system for deriving mesenchymal precursors. Selective culture conditions and fluorescence-activated cell sorting (FACS)-mediated purification yielded multipotent mesenchymal precursors and skeletal myoblasts. Skeletal muscle cells undergo in vitro maturation resulting in myotube formation and spontaneous twitching. We found that hESC-derived skeletal myoblasts were viable after transplantation into the tibialis anterior muscle of SCID/Beige mice, as assessed by bioluminescence imaging. Lack of teratoma formation and evidence of long-term myoblast engraftment suggests considerable potential for future therapeutic applications.

Abstract
Understanding mechanisms that govern cell fate decisions will lead to developing techniques for induction of adult stem cell differentiation to desired cell outcomes and, thus, production of an autologos source of cells for regenerative medicine. Recently, we demonstrated that stem cells derived from adult central nervous system or bone marrow grown with other cell lineages or with more undifferentiated cells sometimes take on those characteristics. This indicates that manipulating extracellular factors may be sufficient to alter some developmental restrictions regulated by the epigenetic system. In this study, using pharmacological agents that interfere with the main components of the epigenetic program such as DNA methylation and histone deacetylation, we induce high-level expression of embryonic and neural stem cell (NSC) marker Sox2 in bone marrow-derived mesenchymal stem cells (MSCs). Exposure of these modified cells to a neural environment via juxtacrine and paracrine interactions promote efficient generation of neural stem-like cells as well as cells with neuronal and glial characteristics. We concluded that the manipulation strategy used in this study can be a useful method for efficient production of NSC-like cells from MSCs.

Abstract
The muscle satellite cell was first described and actually named on the basis of its anatomic location under the basement membrane surrounding each myofiber. For many years following its discovery, electron microscopy provided the only definitive method of identification. More recently, several molecular markers have been described that can be used to detect satellite cells, making them more accessible for study at the light microscope level. Satellite cells supply myonuclei to growing myofibers before becoming mitotically quiescent in muscle as it matures. They are then activated from this quiescent state to fulfill their roles in routine maintenance, hypertrophy, and repair of adult muscle. Because muscle is able to efficiently regenerate after repeated bouts of damage, systems must be in place to maintain a viable satellite cell pool, and it was proposed over 30 years ago that self-renewal was the primary mechanism. Self-renewal entails either a stochastic event or an asymmetrical cell division, where one daughter cell is committed to differentiation whereas the second continues to proliferate or becomes quiescent. This classic model of satellite cell self-renewal and the importance of satellite cells in muscle maintenance and repair have been challenged during the past few years as bone marrow-derived cells and various intramuscular populations were shown to be able to contribute myonuclei and occupy the satellite cell niche. This is a fast-moving and dynamic field, however, and in this review we discuss the evidence that we think puts this enigmatic cell firmly back at the center of adult myogenesis.

Abstract
Several recent reports suggest that there is far more plasticity that previously believed in the developmental potential of bone-marrow-derived cells (BMCs) that can be induced by extracellular developmental signals of other lineages whose nature is still largely unknown. In this study, we demonstrate that bone-marrow-derived mesenchymal stem cells (MSCs) co-cultured with mouse proliferating or fixed (by paraformaldehyde or methanol) neural stem cells (NSCs) generate neural stem cell-like cells with a higher expression of Sox-2 and nestin when grown in NS-A medium supplemented with N2, NSC conditioned medium (NSCcm) and bFGF. These neurally induced MSCs eventually differentiate into beta-III-tubulin and GFAP expressing cells with neuronal and glial morphology when grown an additional week in Neurobasal/B27 without bFGF. We conclude that juxtacrine interaction between NSCs and MSCs combined with soluble factors released from NSCs are important for generation of neural-like cells from bone-marrow-derived adherent MSCs.

Abstract
We investigated whether the vessel-associated or endothelial cells within mouse embryo muscles can be a source of myogenic progenitors. Immunodetection of the stem cell surface markers, CD34 and Flk1, which are known to characterize the endothelial lineage, was done throughout the course of embryo muscle development. Both markers appeared to be restricted to the vessel-associated cells. On the basis of CD34 labeling, the reactive cells were purified by magnetic-bead selection from the limb muscles of 17-dpc desmin+/-LacZ mouse embryos and characterized by fluorescence-activated cell sorting. The cells in the selected CD34(+) population appeared to be approximately 95% positive for Flk1, but usually negative for CD45. We demonstrated that in vitro the CD34(+)/Flk1(+) population differentiated into endothelial cells and skeletal myofibers. When transplanted into mdx mouse muscle, this population displayed a high propensity to disperse within the recipient muscle, fuse with the host myofibers, and restore dystrophin expression. The marked ability of the embryonic muscle endothelial cells to activate myogenic program could be related to their somitic origin.

Abstract
Growth, repair, and regeneration of adult skeletal muscle depends on the persistence of satellite cells: muscle stem cells resident beneath the basal lamina that surrounds each myofiber. However, how the satellite cell compartment is maintained is unclear. Here, we use cultured myofibers to model muscle regeneration and show that satellite cells adopt divergent fates. Quiescent satellite cells are synchronously activated to coexpress the transcription factors Pax7 and MyoD. Most then proliferate, down-regulate Pax7, and differentiate. In contrast, other proliferating cells maintain Pax7 but lose MyoD and withdraw from immediate differentiation. These cells are typically located in clusters, together with Pax7−ve progeny destined for differentiation. Some of the Pax7+ve/MyoD−ve cells then leave the cell cycle, thus regaining the quiescent satellite cell phenotype. Significantly, noncycling cells contained within a cluster can be stimulated to proliferate again. These observations suggest that satellite cells either differentiate or switch from terminal myogenesis to maintain the satellite cell pool.
