Surprisingly, the knockout of one or both nidogens does not cause defects in all tissues or in all basement membranes. In this study, we have elucidated the appearance of the major basement membrane components in adult murine kidney lacking nidogen- 1, nidogen- 2, or both nidogens. To this end, we localized laminin- 111, perlecan, and collagen type IV in knockout mice, heterozygous (+/-) or homozygous (-/-) for the nidogen- 1 gene, the nidogen- 2 gene, or both nidogen genes with the help of light microscopic immunostaining. We also performed immunogold histochemistry to determine the occurrence of these molecules in the murine kidney at the ultrastructural level. The renal basement membranes of single knockout mice contained a similar distribution of laminin- 111, perlecan, and collagen type IV compared to heterozygous mice. In nidogen double- knockout animals, the basement membrane underlying the tubular epithelium was sometimes altered, giving a diffuse and thickened pattern, or was totally absent. The normal or thickened basement membrane of double- knockout mice also showed a similar distribution of laminin- 111, perlecan, and collagen type IV. The results indicate that the lack of nidogen- 1, nidogen- 2, or both nidogens, plays no crucial role in the occurrence and localization of laminin- 111, collagen type IV, and perlecan in murine tubular renal basement membranes."],["dc.identifier.isi","000247757300003"],["dc.identifier.pmid","17616934"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/50403"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","F Hernandez"],["dc.relation.issn","0213-3911"],["dc.title","The absence of one or both nidogens does not alter basement membrane composition in adult murine kidney"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

During murine embryogenesis, nearly all BMs of mesenchymal origin express perlecan, and it is believed to participate in the supramolecular assembly of BMs. However, the distribution of perlecan in human embryonic and fetal tissues is widely unknown, except for cartilage anlagen of developing extremities and the fetal spine. Clinical syndromes, caused by perlecan-associated mutations or gene-defects, suggest its multifunctional involvement during human development. Here we reveal the immunohistochemistry of perlecan domains III and V during human development from gestational weeks (gw) 6 to 12 in basement membrane zones (BMZs) of the developing brain, nervous system, blood vessels, skin, lung, heart, kidney, liver, intestine and skeletal system. Interestingly, a difference in the distribution of the two perlecan domains was found in the endoneurium of ganglia. Domain III is strongly present from gw 6 onwards, while domain V shows attenuated expression at this stage and has been detected abundantly only from gw 8 onwards, possibly indicating vascularization of the endoneurium during this early stage. We found perlecan to be present particularly at those stages of human development where epithelial-mesenchymal interactions occur."],["dc.identifier.isi","000266407500007"],["dc.identifier.pmid","19475532"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/16364"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","F Hernandez"],["dc.relation.issn","0213-3911"],["dc.title","Tissue distribution of perlecan domains III and V during embryonic and fetal human development"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
