Different imaging techniques (optical microscopy, immunohistochemistry, scanning (SEM) and transmission (TEM) electron microscopy) served as tools to proof the sustainability of the model.</p><p><strong>Results: </strong>We demonstrated the feasibility of creating a robust GCPM model. We showed that the model is reproducible under various conditions (6-, 12-, and 24-wells) and pre-analytical processing is possible. The imaging was feasible and allowed the comparison of morphological changes on the GCPM model to normal human peritoneum.</p><p><strong>Conclusions: </strong>We established a reproducible and robust organotypic model of GCPM which can be used to generate deeper knowledge on the pathophysiology of GCPM and might serve as a platform for testing different chemotherapy schemes in order to establish a personalized treatment for patients with GCPM.</p>","PeriodicalId":20231,"journal":{"name":"Pleura and Peritoneum","volume":"10 1","pages":"11-17"},"PeriodicalIF":1.4,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12016017/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143978911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
