Proteomics results identified salivary and urinary proteins through comparative proteomics analysis between pre and post PLE treatments. Literature search showed no previous implications of SPARC-like protein 1 (SPARC-L 1), leukocyte-associated immunoglobulin-like receptor-1 (LAIR-1), immunoglobulin kappa variable 4 (IGKV4; V4-1), and complement C7 with diabetes (Table 3). Of these, a renal glycoprotein uromdulin, also known as Tamm-Horsfall protein (Lo et al., 2014), showed down-regulation in prediabetic subjects after the PLE treatment whereas, Ezrin (Wasik et al., 2014), which is involved in diabetes and obesity, was found to be upregulated due to PLE-treatment, suggesting ameliorative effects of PLE. Physiological functions of uromodulin are still elusive, despite the fact that it is involved in the pathophysiology of various diseases including diabetes, renal inflammation, acute and chronic kidney diseases. Conventionally, uromodulin was regarded as an instigator in kidney injury; however ...

Quebec Platelet Disorder (QPD) is a rare, autosomal dominant bleeding disorder described in a family from the province of Quebec in Canada. Individuals with QPD are at risk for experiencing a number of bleeding symptoms, including joint bleeds, hematuria, and large bruising. In 2010, the genetic cause of QPD has been determined as a mutation involving an extra copy of the uPA (urokinase plasminogen activator) gene http://bloodjournal.hematologylibrary.org/content/115/6/1264.long.[permanent dead link] The mutation causes overproduction of an enzyme that accelerates blood clot breakdown. The disorder is characterized by large amounts of the fibrinolytic enzyme urokinase-type plasminogen activator (u-PA) in platelets. Consequently, stored platelet plasminogen is converted to plasmin, which is thought to play a role in degrading a number of proteins stored in platelet α-granules. These proteins include platelet factor V, Von Willebrand factor, fibrinogen, thrombospondin-1, and osteonectin. There is ...

Approach and Results-Among various ABC transporters, ABCB6 was highly expressed in megakaryocyte progenitors, exhibiting the same pattern of expression of genes involved in heme synthesis pathway. Transplantation of Abcb6−/− bone marrow into Ldlr−/− recipient mice resulted in expansion and proliferation of megakaryocyte progenitors, attributable to increased reactive oxygen species production in response to porphyrin loading. The enhanced megakaryopoiesis in Abcb6−/− bone marrow-transplanted mice was further illustrated by increased platelet counts, mean platelet volume, and platelet activity. Platelets from Abcb6−/− bone marrow-transplanted mice had higher levels of chemokine (C-C motif) ligand 5, which was associated with increased plasma chemokine (C-C motif) ligand 5 levels. There were also increased platelet-leukocyte aggregates, which resulted in leukocyte activation. Abcb6−/− bone marrow-transplanted mice had accelerated atherosclerosis which was associated with ...

PLAU is a protease that converts plasminogen to plasmin. It appears to affect murine ageing: its overexpression in the brain diminishes food consumption and extends longevity probably through a mechanism similar to caloric restriction [13]. It is unclear at present whether PLAU affects human ageing, despite some evidence linking PLAU to age-related neurological diseases [374]. ...

Because of the scarcity of megakaryocytes in hematopoietic tissues, studying megakaryopoiesis heavily relies on the availability of appropriate cellular models. Here, we report the establishment of a new mouse embryonic stem (ES) cell-derived megakaryocytic cell line, MKD1. The cells are factor-dependent, their cell surface immunophenotype and gene expression profile closely resemble that of primary megakaryocyte progenitors (MkPs) and they further differentiate along the megakaryocyte lineage upon valproic acid treatment. At a functional level, we show that ablation of SCL expression, a transcription factor critical for MkP maturation, leads to gene expression alterations similar to that observed in primary, Scl-excised MkPs. Moreover, the cell line is amenable to biochemical and transcriptional analyses, as we report for GpVI, a direct target of SCL. Thus, the MKD1 cell line offers a pertinent experimental model to study the cellular and molecular mechanisms underlying MkP biology and more broadly

Interestingly, bioG1s cultures produced significantly fewer megakaryocytes providing a first clue that megakaryocyte differentiation is impaired by GATA1s. In order to obtain a more complete initial view of megakaryocyte differentiation we analysed kit (marker of immature hemopoietic cells) and CD41 (marker of megakaryocyte maturation) expression at d6 and d12 of culture (Figure 1E; megakaryocyte differentiation from embryonic stem cells (ESC). from GATA1s-expressing TMD cells failed to complete erythropoiesis.13 This suggests that the N-terminal of GATA1 has a specific developmental role in restraining megakaryocyte production and is required for terminal red cell maturation. However, it is unclear which developmental hemopoietic cell populations require the N-terminus of GATA1 and the cellular and molecular mechanisms responsible for perturbed hemopoiesis in GATA1s cells. In order to identify the cellular populations most perturbed by GATA1s, we studied hemopoietic differentiation from both ...

Platelets, small anucleated blood cells responsible for hemostasis, interact at sights of injury with several exposed extracellular matrix (ECM) proteins through specific receptors. Ligand binding leads to activation, adhesion and aggregation of platelets. Already megakaryocytes (MKs), the immediate precursor cells in bone marrow (BM), are in constant contact to these ECM proteins (ECMP). The interaction of ECMP with MKs is, in contrast to platelets, less well understood. It is therefore important to study how MKs interact with sinusoids via the underlying ECMP. This thesis addresses three major topics to elucidate these interactions and their role in platelet biogenesis. First, we studied the topology of ECMP within BM and their impact on proplatelet formation (PPF) in vitro. By establishing a four-color immunofluorescence microscopy we localized collagens and other ECMP and determined their degree of contact towards vessels and megakaryocytes (MKs). In in vitro assays we could demonstrate that ...

In this study, we demonstrate that (1) BM FRC-like cells are periarteriolar stromal cells that express PDPN in the BM, (2) PDPN binding to CLEC-2 positively regulates megakaryocyte expansion, and (3) CLEC-2/PDPN binding stimulates BM FRC-like cells to secrete CCL5 to promote PPF in megakaryocytes. The CLEC-2/PDPN axis between megakaryocytes and BM FRC-like cells constitutes a reciprocal interaction that generates the megakaryopoietic microenvironment at periarteriolar sites in the BM (supplemental Figure 7). These data support our hypothesis that BM FRC-like cells provide a CLEC-2/PDPN-dependent niche that potentiates megakaryocyte expansion and CCL5-mediated PPF.. In megakaryopoiesis, phosphatidylinositol 3-kinase/Akt signaling promotes the proliferation of megakaryocyte progenitors,36,37 and p44/42 signaling regulates megakaryocytic differentiation.38 Interestingly, p38 does not appear to be involved in megakaryopoietic processes.39 In this study, we found that PDPN binding to CLEC-2 increases ...

Coloured scanning electron micrograph (SEM) of a megakaryocyte. Megakaryocytes are derived from hematopoietic stem cell precursor cells in the bone marrow. During megakaryocyte maturation the cell grows in size and replicates its DNA without cytokinesis, a process called endomitosis. As a result, the nucleus of the megakaryocyte may contain up to 32 copies of the normal complement of DNA in a human cell. Megakaryocytes are responsible for the production of blood thrombocytes (platelets), which are necessary for normal blood clotting. Platelet production begins with the extension of large pseudopodia from the megakaryocyte cell surface that form thin tube-like cytoplasmic extensions (with bulbous thickenings) called proplatelets. As the proplatelet development continues small platelets can be seen forming along the proplatelet processes. Each megakaryocyte produces and releases hundreds of platelets into the circulatory system. Magnification: x2,130 when shortest axis printed at 25mm. - Stock Image C036

Megakaryocytes generate platelets by remodeling their cytoplasm into long proplatelet extensions, which serve as assembly lines for platelet production. Although the mechanics of proplatelet elongation have been studied, the terminal steps of proplatelet maturation and platelet release remain poorly understood. To elucidate this process, released proplatelets were isolated, and their conversion into individual platelets was assessed. This enabled us to (a) define and quantify the different stages in platelet maturation, (b) identify a new intermediate stage in platelet production, the preplatelet, (c) delineate the cytoskeletal mechanics involved in preplatelet/proplatelet interconversion, and (d) model proplatelet fission and platelet release. Preplatelets are anucleate discoid particles 2-10 \(\mu\)m across that have the capacity to convert reversibly into elongated proplatelets by twisting microtubule-based forces that can be visualized in proplatelets expressing GFP-\(\beta\)1-tubulin. The ...

Very successful tethering and overstretching. Tethers are every where: {{#widget:YouTube,id=XDQkC9saRjw,600px}} Tethers are easily found in both the samples. Tethers and overstretching in the new dna-sample proves that the PCR Ant ran, worked. And we are set for unzipping. In some of the overstretching profiles we see the profile on a slope due to the sum signal change at QPD. This problem was due to the ND filter being very close to QPD, as ND filter was moved out, the problem is solved. Another problem was the AOM oscillations, which is due to the crystal, as the laser power modulated by some external source in-front of the AOM-crystal. Due to that I moved the newly constructed shutter after the AOM. So at this point we have solved all the major problems of signal drift at QPD. There is a little momentarily drift because of eclipsing ND filters in-front of the steering assembly first lens, but this is not a problem since we take the data without having that ND filter in way.

The latter work was performed with murine species and, of note, many differences have been emphasized in megakaryocyte localization and ultrastructure of proplatelet formation, between mice and humans.32 The present study performed on human MKs sheds additional light on how these large protrusions can be induced to fragment into small platelets by shear forces in flowing blood. This is also in keeping with evidence that the pulmonary circulation could be an important site of platelet production, as the lung capillaries would be the first to be encountered by cells leaving the bone marrow.28 Indeed, the large cytoplasmic fragments and the isolated platelet-sized fragments that we observed in real time to form on the coverslip during the flow assay resembled those seen downstream of the pulmonary circulation in vivo.33 In our conditions, high shear rates were essential to proplatelet and platelet formation during an exposure time of 20 minutes. In contrast, no proplatelet or platelet was generated ...

BACKGROUND AND OBJECTIVES: Megakaryocyte (Mk) engraftment is often poor and delayed after cord blood (CB) transplantation. Ex vivo manipulations of the cells that will be infused may be a way to achieve better Mk engraftment. In this study we investigated the ability of different hematopoietic growth factor combinations to generate large numbers of Mk cells ex vivo. DESIGN AND METHODS: To find the best cytokine combination capable of generating large numbers of Mks, baseline CB CD34+ (bCD34+) cells and CD34+ and CD34- cells, immunoselected after 4 weeks of expansion with thrombopoietin (TPO), stem cell factor (SCF) and Flt-3 ligand (FL) (eCD34+, eCD34-), were further cultured in the presence of different cytokine combinations (containing interleukin(IL)-3, SCF, TPO and IL-6). To evaluate Mk reconstitution in vivo, Mk-committed cells, generated during 10 days of in vitro culture, were injected into NOD/SCID mice and the kinetics of human platelet production was evaluated. RESULTS: TPO and SCF ...

The first presentation was part of the nursing preconference session and included clinical and laboratory evaluation of inherited platelet disorders. Unlike hemophilia, diagnosing inherited platelet disorders can be a complex process, including careful review of the patient and familys medical history, physical exam and laboratory testing. It is often frustrating for families as lab testing is very expensive and may require repeated lab draws, based on the results of previous tests. As medical science knowledge grows, the best strategies for diagnosing platelet disorders will likely change. Increasingly, we are understanding the platelet disorders are a very heterogeneous group, meaning that we are finding more and more types of platelet disorders. For example, platelet dense granuole deficiencies may be as common as von Willebrand Disease! We are also recognizing the need for newer tests that would automate and standardize testing for greater accessibility and reliability. For patients, the ...

Interleukin 11 (IL-11) is a member of the gp130 family of cytokines. IL-11 functions to promote hematopoietic stem cell proliferation and megakaryocyte differentiation. In non-hematopoietic cell populations, IL-11 stimulates acute-phase proteins, modulates the development of immunoglobulin-producing B cells, and regulates bone turnover. IL-11 binds the IL-11Rα receptor to activate JAK downstream signaling.

Acute Megakaryoblastic Leukemia (AMKL) is a rare form of pediatric leukemia that disproportionately affects children. AMKL associated with the chromosomal translocation fusing RNA Binding Motif 15 gene (RBM15) on chromosome 1 upstream of the transcriptional cofactor Megakaryoblastic Leukemia 1 gene (MKL1) on chromosome 22 (t1;22), is most commonly diagnosed in infants less than three months of age and requires aggressive medical management. Thus, it is likely that the leukemia originates in utero when the hematopoietic system is in its embryonic or fetal stages. We have successfully recapitulated megkaryopoiesis in vitro using human embryonic stem cells and established a model system in which to study megakaryocyte differentiation. Human embryonic stem cells (hESCs) offer a mechanism to study embryogenesis and to understand the processes of fetal blood maturation and leukemia development. We seek to further define the roles of MKL1 and RBM15 during hESC-derived megakaryopoiesis. Furthermore, we ...

DGs have long been considered to be fully formed in MKs, because MKs accumulate serotonin in dense structures26,43,44 and harbor a secretable pool of ADP.45 However, our data suggest that this may not be the case. Our findings demonstrate that although mepacrine uniquely labels DGs in platelets, it incorporates only as a weak base into acidic endolysosomal organelles of MKs and that mepacrine-labeled structures in MKs do not necessarily become dense granules. Mepacrine-labeled structures that are distinct from acidic endolysosomes become evident only in proplatelets, which represent the final stage of MK maturation. These data have important implications for the timing and mechanisms underlying DG maturation and for how diseases such as HPS affect them.. DGs in platelets are characterized as storage compartments for calcium, serotonin, adenine nucleotides, and polyphosphate. Serotonin is also actively incorporated into storage compartments in MKs26,43⇓⇓-46 by a transporter.47 If these ...

In endocytosis small GTPases Rab5 and Rab7 act like molecular switches and regulate vesicular transport and membrane trafficking. Rab5 represents a marker of early endosomes which is essential for homotypic and heterotypic fusion as well for endosome motility while Rab7 represents a marker of late endosomes. Conversion from Rab5 to Rab7 is important for the course of an endolysosomal path. Purpose of this thesis was to investigate correlation between endosome maturation and proplatelet formation. We used Western blot analysis to examine the level of expression of early (Rab5), late (Rab7) and recycling (Rab11) endosomes in different maturation stages of mouse megakaryocytes and platelets. By immunofluorescence and confocal microscopy, we analyzed the localization of early (Rab5, EEA1) and late (Rab7, LAMP1) endosomes considering the maturation stage of megakaryocytes. In addition, we treated megakaryocytes with inhibitors that cause rapid alkalinization of acidic organelles and block conversion ...

During thrombopoiesis, maturing megakaryocytes (MKs) migrate within the complex bone marrow stromal microenvironment from the proliferative osteoblastic niche to the capillary-rich vascular niche where proplatelet formation and platelet release occurs. This physiologic process involves proliferation, differentiation, migration, and maturation of MKs before platelet production occurs. In this study, we report a role for the glycoprotein PECAM-1 in thrombopoiesis. We show that following induced thrombocytopenia, recovery of the peripheral platelet count is impaired in PECAM-1-deficient mice. Whereas MK maturation, proplatelet formation, and platelet production under in vitro conditions were unaffected, we identified a migration defect in PECAM-1-deficient MKs in response to a gradient of stromal cell-derived factor 1 (SDF1), a major chemokine regulating MK migration within the bone marrow. This defect could be explained by defective PECAM-1(-/-) MK polarization of the SDF1 receptor CXCR4 and an increase

AMKL is a heterogeneous subtype of AML generally associated with poor prognosis. Challenges in understanding the molecular basis of this disease derive in part from the difficulties in obtaining a sufficient amount of material, which together with the lack of experimental model limits the development of novel therapeutic strategies. Using a xenotransplantation approach with primary human AMKL patient samples into immunodeficient mice, we have established novel models of AMKL recapitulating features of the human disease. The leukemic blasts engrafted in immunodeficient recipient mice allowed the identification and characterization of novel genetic lesions and were relevant models to test the efficacy of AURKA inhibitors as a potential therapeutic strategy for the treatment of AMKL with various genetic alterations.. Xenotransplantation has been widely used as a strategy to propagate human leukemic cells in immunodeficient mice. To date however, no specific study of AMKL has been reported. In this ...
