METHODS: Livers of dipeptidyl peptidase IV (DPPIV)-deficient rats were pre-conditioned with external beam IR (25 Gy) delivered to two-thirds of the right liver lobules followed by a one-third PH of the untreated lobule. DPPIV-positive liver cells (NPC preparations enriched for liver sinusoidal endothelial cells (LSECs) and hepatocytes) were transplanted via the spleen into the recipient livers. The extent and quality of donor cell engraftment and growth was studied over a long-term interval of 16 wk after transplantation. RESULTS: Host liver staining demonstrated 3 different repopulation types. Well defined clusters of donor-derived hepatocytes with canalicular expression of DPPIV were detectable either adjacent to or in between large areas of donor cells (covering up to 90% of the section plane) co-expressing the endothelial marker platelet endothelial cell adhesion molecule. The third type consisted of formations of DPPIV-positive duct-like structures which co-localized with biliary epithelial CD49f. CONCLUSION: Liver IR and PH as a preconditioning stimulus enables multiple cell liver repopulation by donor hepatocytes, LSECs, and bile duct cells."],["dc.identifier.fs","574471"],["dc.identifier.pmid","20712054"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/6866"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/61286"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.issn","1007-9327"],["dc.relation.orgunit","Universitätsmedizin Göttingen"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject.ddc","610"],["dc.subject.mesh","Animals"],["dc.subject.mesh","Bile Ducts"],["dc.subject.mesh","Cell Proliferation"],["dc.subject.mesh","Cell Survival"],["dc.subject.mesh","Dipeptidyl Peptidase 4"],["dc.subject.mesh","Endothelial Cells"],["dc.subject.mesh","Hepatectomy"],["dc.subject.mesh","Hepatocytes"],["dc.subject.mesh","Liver"],["dc.subject.mesh","Liver Regeneration"],["dc.subject.mesh","Rats"],["dc.subject.mesh","Rats, Inbred F344"],["dc.subject.mesh","Rats, Transgenic"],["dc.subject.mesh","Time Factors"],["dc.subject.mesh","Transplantation Conditioning"],["dc.title","Liver sinusoidal endothelial and biliary cell repopulation following irradiation and partial hepatectomy."],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]Details PMID PMC2011Journal Article [["dc.bibliographiccitation.firstpage","37"],["dc.bibliographiccitation.issue","1"],["dc.bibliographiccitation.journal","International Journal of Colorectal Disease"],["dc.bibliographiccitation.lastpage","43"],["dc.bibliographiccitation.volume","26"],["dc.contributor.author","Krause, Petra"],["dc.contributor.author","Bobisch, Nina S."],["dc.contributor.author","Thelen, Paul"],["dc.contributor.author","Koehler, Karola"],["dc.contributor.author","Koenig, Sarah"],["dc.contributor.author","Becker, Heinz"],["dc.contributor.author","Leister, Ingo"],["dc.date.accessioned","2018-11-07T09:01:27Z"],["dc.date.available","2018-11-07T09:01:27Z"],["dc.date.issued","2011"],["dc.description.abstract","Laparoscopic surgery in the treatment of colon carcinoma causes pH value alterations as well as changes in fibrinolytic activity. This results in enhanced proliferation of colon carcinoma cells in vitro and also in enhanced growth of liver metastasis when compared to isobaric (gasless) laparoscopy in vivo. So far, the direct influence of CO2 pneumoperitoneum on the invasiveness and metastatic capabilities of colon cancer cells remains unclear. We therefore evaluated transcripts of the uPA system. The influence of CO2 pneumoperitoneum on the gene expression of plasminogen activator inhibitor-1 (PAI-1), urokinase-type plasminogen activator (uPA), and tissue-type plasminogen activator (tPA) was investigated in colon carcinoma cell lines (HT116, SW48, and WiDr) and mesothelial cells employing a pneumoperitoneum chamber in vitro. Quantitative gene expression data were collected using real-time RT-PCR and statistical analysis was performed by means of analysis of variance and Bonferroni correction. The expression of uPA and PAI-1 was increased in colon carcinoma cell lines when cultivated at pH 6.1, a value corresponding to intraabdominal pH values during CO2 insufflation. Elevated PAI-1 mRNA levels were also observed when CO2 was simultaneously applied with a pressure of 10 mmHg. In contrast, there were no significant changes in mesothelial cells in the investigated parameter. The conditions of CO2 pneumoperitoneum cause changes in the expression of genes controlling the fibrinolytic activity. The increase of PAI-1 and uPA can contribute to the enhancement of metastasis and invasive potential of tumour cells. Therefore, changes in the conditions of laparoscopy may well optimise laparoscopic therapy in colon cancer."],["dc.identifier.doi","10.1007/s00384-010-1062-y"],["dc.identifier.isi","000285785600005"],["dc.identifier.pmid","20931209"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/6937"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/24426"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","0179-1958"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","The plasminogen activator inhibitor system in colon cancer cell lines is influenced by the CO2 pneumoperitoneum"],["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"]]Details DOI PMID PMC WOS
