De lactibus, sive lacteis venis, quarto vasorum mesaraicorum genere, novo invento Gasparis Asellii Cremo. Dissertatio. (MDCXXIIX), Milan; 1628.), structure, function, development and evolution of this so-called ‘second’ vascular system are still enigmatic. Interest in the LVS was low because it was (and is) hardly visible, and its diseases are not as life-threatening as those of the blood vascular system. It is not uncommon for patients with lymphedema to be told that yes, they can live with it. Usually, the functions of the LVS are discussed in terms of fluid homeostasis, uptake of chylomicrons from the gut, and immune cell circulation. However, the broad molecular equipment of lymphatic endothelial cells suggests that they possess many more functions, which are also reflected in the pathophysiology of the system. With some specific exceptions, lymphatics develop in all organs. Although basic structure and function are the same regardless their position in the body wall or the internal organs, there are important site-specific characteristics. We discuss common structure and function of lymphatics; and point to important functions for hyaluronan turn-over, salt balance, coagulation, extracellular matrix production, adipose tissue development and potential appetite regulation, and the influence of hypoxia on the regulation of these functions. Differences with respect to the embryonic origin and molecular equipment between somatic and splanchnic lymphatics are discussed with a side-view on the phylogeny of the LVS. The functions of the lymphatic vasculature are much broader than generally thought, and lymphatic research will have many interesting and surprising aspects to offer in the future."],["dc.identifier.citation","Cell & Bioscience. 2022 Sep 15;12(1):157"],["dc.identifier.doi","10.1186/s13578-022-00898-0"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/114251"],["dc.language.iso","en"],["dc.relation.orgunit","Universitätsmedizin Göttingen"],["dc.rights","CC BY 4.0"],["dc.rights.holder","The Author(s)"],["dc.subject","Initial lymphatics"],["dc.subject","Lymphatic collector"],["dc.subject","Lymphangiogenesis"],["dc.subject","Circulating endothelial precursor cells"],["dc.subject","Pacemaker cell"],["dc.subject","Smooth muscle cell origin"],["dc.subject","Sphingosine-1-phosphate"],["dc.subject","Melanocortin-2 receptor accessory protein-2"],["dc.title","The lymphatic vascular system: much more than just a sewer"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Material and methods Three vertical defects were created in the maxillary alveolar ridge of six Beagle dogs 3months after the removal of all premolars. One defect in each dog was filled with tricalciumphosphate/hydroxylapatite (TCP/HA) grafting material and stabilized using a poloxamer hydrogel (test group). Defects filled with grafting material only and covered with a collagen membrane as well as empty defects served as controls (controls 1 & 2). Bone formation in the defects was evaluated after 14weeks of healing using histomorphometry on undecalcified thick-section specimens. Results There was no difference between the test group and the controls with respect to the amount of newly formed bone, percentage of bone fill, and bone density. The mean maximum bone height within the augmented area was the only parameter that was significantly higher in the test group compared with empty defects. The use of the poloxamer gel did not result in a better preservation of ridge shape compared with the group of augmentations covered with a collagen membrane.

Due to the lack of appropriate in vivo models NHL research is mainly performed in vitro. Here, we studied the use of the chick chorioallantoic membrane (CAM) for the generation of human BL xenograft tumors, which we compared with known characteristics of the human disease. Methods: In order to generate experimental BL tumors, we inoculated human BL2B95 and BL2-GFP cells on the CAM. BL2B95 xenograft-tumors were grown for seven days and subsequently analyzed with transmission electron and immunofluorescence microscopy, as well as histological staining approaches. BL2-GFP cells were studied at regular intervals up to seven days, and their metastatic behavior was visualized with intravital immunofluorescence techniques. Results: Xenografted BL2B95 cells formed solid tumors in the CAM model with a Ki67-index greater than 90%, preservation of typical tumor markers (CD10, CD19, CD20), a 'starry sky' morphology, production of agyrophilic fibers in the stroma, formation of blood and lymphatic vessels and lymphogenic dissemination of BL2B95 to distant sites. We identified macrophages, lymphocytes and heterophilic granulocytes (chick homolog of neutrophils) as the most abundant immune cells in the experimental tumors. BL2-GFP cells could be traced in real-time during their distribution in the CAM, and the first signs for their dissemination were visible after 2-3 days. Conclusions: We show that xenografted BL2B95 cells generate tumors in the CAM with a high degree of cellular, molecular and proliferative concord with the human disease, supporting the application of the CAM model for NHL research with a focus on tumor-stroma interactions. Additionally we report that BL2-GFP cells, grafted on the CAM of ex ovo cultured chick embryos, provide a powerful tool to study lymphogenic dissemination in real-time."],["dc.description.sponsorship","Deutsche Forschungsgemeinschaft [FOR942/12-1, GRK1034]"],["dc.identifier.doi","10.1186/1471-2407-14-339"],["dc.identifier.isi","000338141900001"],["dc.identifier.pmid","24884418"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/10149"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/33449"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Biomed Central Ltd"],["dc.relation.issn","1471-2407"],["dc.rights","CC BY 2.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/2.0"],["dc.title","The chick chorioallantoic membrane as an in vivo xenograft model for Burkitt lymphoma"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Prox1-null mice show severe deficiencies in liver development, although the underlying mechanisms are unknown. We have studied the effects of Prox1 on the transcriptional profile of met-murine hepatocytes (MMH) obtained on embryonic day 14 (ED14). These immortalized murine hepatoblasts express numerous hepatoblast markers, but not Prox1. We have performed stable transfection with Prox1 cDNA, analyzed the transcriptome with Agilent mouse whole-genome microarrays, and validated genes by quantitative reverse transcription/polymerase chain reaction. We have observed the up-regulation of 22 genes and the down-regulation of 232 genes, by more than 12-fold. Many of these genes are involved in metabolic hepatocyte functions and may be regulated by Prox1 directly or indirectly, e.g., by the down-regulation of hepatocyte nuclear factor 4 alpha. Prox1 induces the down-regulation of transcription factors that are highly expressed in neighboring endodermal organs, suggesting a function during hepatoblast commitment. Prox1 does not influence the proliferative activity of MMH but regulates genes involved in liver morphogenesis. We have observed the up-regulation of both type-IV alpha 3 procollagen and functionally active matrix metalloproteinase-2 (MMP-2), an observation that places Prox1 at the center of liver matrix turnover. This is consistent with MMP-2 expression in hepatoblasts during liver development and with the persistence of a basal lamina around the liver bud in Prox1-deficient mice.
