Light-Sheet Imaging of Collagen in Renal Tissue in Aqueous and Anhydrous Conditions / "Light sheet"-mikroskopi av kollagen i njurvävnad i vattenhaltiga och vattenfria förhållanden

Näsman, Felicia January 2023 (has links)
Chronic kidney disease is a progressive kidney disease that affects approximately one tenth of the world population. In almost all cases of progressive, end-stage kidney disease, fibrosis is seen. Renal fibrosis is a condition of the kidneys in which collagens and other proteins accumulate in the extracellular matrix of the kidneys. The aim of the project was to explore the use of Fast Green to visualize collagen in renal tissue using light-sheet microscopy. A healthy sample and a diseased sample of renal tissue was imaged in aqueous and anhydrous conditions and a comparison of the difference in staining pattern between the conditions was performed. There was a clear difference in staining pattern between the two conditions, where the samples prepared in anhydrous conditions showed a higher staining specificity to collagen as described previously for other types of tissue. An evaluation of the differences in collagen expression between the healthy and the diseased sample was performed as well. There was a visible difference between them where a higher expression of collagen was observed in numerous tubuli, indicative of pathological scarring. / Kronisk njursjukdom är en progressiv njursjukdom som påverkar approximativt en tiondel av världens befolkning. I alla progressiva njursjukdomar ses så kallad njurfibros. Njurfibros är ett tillstånd då kollagen och andra proteiner ansamlas i njurarnas extracellulära matris. Målet med projektet var att utforska användningen av Fast Green för att visualisera kollagen i njurvävnad med ”Light sheet”-mikroskopi. Vävnadsproverfrån frisk vävnad och sjuk vävnad avbildades i vattenhaltiga och vattenfria förhållanden och en jämförelse av inmärkningen mellan förhållandena utfördes. Det var en tydlig skillnad i inmärkningen mellan de två förhållandena, där det i de vattenfria proven observerades att Fast Green märkte in kollagen med högre specificitet. En jämförelse av skillnaderna i kollagenuttryck mellan det friska och det sjuka provet utfördes. Det var tydliga skillnader mellan proven, där ett stort antalkollagen-påverkade tubuli kunde observeras i det sjuka provet.
