ScRNA sequencing analysis for human ureters and patient derived ureter oragnoid

ABSTRACT: Tissue engineering offers a promising treatment strategy for ureteral strictures. Successful ureter engineering is necessitated by detailed understanding of the tissue architecture, cellular heterogeneity, and signaling pathways underlying regeneration. We define and spatially map cell populations within the human ureter by using a combinatorial approach: single-cell RNA sequencing, 10X Visium spatial transciptomics, and immunofluorescence. The stromal and urothelial cell populations are analyzed in detail, and we infer potential cell-cell communication networks underpinning the bi-directional crosstalk between these compartments. Specifically, we analyze and experimentally validate the importance of Sonic Hedgehog (SHH) signaling pathway in adult stem cell maintenance. The SHH-expressing basal cells support organoid generation in vitro, and accurately predict the differentiation trajectory of basal stem cells, to terminally differentiated umbrella cells, in vivo. Our results highlight essential processes involved in adult ureter tissue homeostasis, and provide a toolkit for guiding ureter tissue engineering.

Cytokeratin 15 marks basal epithelia in developing ureters and is upregulated in a subset of urothelial transitional cell carcinomas

Project description:The mammalian ureter contains a water-tight epithelium surrounded by smooth muscle. Key molecules have been defined which regulate ureteric bud initiation and drive the differentiation of ureteric mesenchyme into peristaltic smooth muscle. Less is known about mechanisms underlying the developmental patterning of the multilayered epithelium characterising the mature ureter. In skin, which also contains a multilayered epithelium, cytokeratin 15 (CK15), an intermediate filament protein, is a marker for cells whose progeny contribute to epidermal regeneration following wounding. Moreover, CK15+ precursor cells in skin can give rise to basal cell carcinomas. In the current study, using transcriptome microarrays of embryonic wild type mouse ureters, we detected Krt15, coding for CK15.

Gene expression analysis using the ureters of normal and ureteritis mice

Project description:Analysis of ureters of idiopathic ureteritis mice. The B cell functions associated genes were upregulated in the diseased ureters compared to nomal ureter. These results provide a basical information of molecular pathology in idiopathic ureteritis. In the study, the normal ureter (n=3) and diseased ureter (n=3) were used. The total RNA sample of each group was collected to 1 sample, 36,142 genes expressions were compared between these groups.

Mouse ureter: wild type vs miR-143/145 knock out

Project description:mRNA profiling of mouse ureters comparing wild-type ureter vs. ureters from mice having whole body deletion of miR-143 and miR-145 which results in abnormal ureter peristalsis and hydronephrosis We used microarrays to detail the global program of gene expression in wild-type and miR-143/145-deficient ureters which revealed dysregulation of genes linked to smooth muscle morphology and function.
