In this respect, patient-derived cancer organoids have been developed as preclinical models of various human cancers, with significant advantages over previous cancer models including patient-derived xenografts and cell lines. We recently reported a culture system of patient-derived lung cancer organoids (LCOs) that retain the characteristics of patients’ tumors. Here, we describe a detailed protocol for establishing LCOs from surgically resected tumor tissues and endoscopic biopsy samples. This method improves the efficiency of setting up LCOs composed of pure cancer cells and describes an additional procedure for reconstructing LCOs after cryopreservation. We confirmed that stored LCOs had the ability to self-organize and retain the morphological and genetic characteristics of their parental tissues. They also maintained their responsive properties to certain anticancer drugs after thawing. In conclusion, our method efficiently generates LCOs that enable anticancer drug screening at the individual patient level.","PeriodicalId":100198,"journal":{"name":"Brain Organoid and Systems Neuroscience Journal","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81159186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cell lines have been modified to reflect researchers’ specific purposes, and in vitro experiments have become fundamental for biological studies, with an ability to replace in vivo experiments. However, immortalized cell lines and cancer-derived cell lines have the limitation of losing their inherent properties, potentially resulting in changes in signaling pathways and cell metabolism. These limitations have made it necessary for researchers to find a novel way to overcome the limitations of cell lines. In recent years, organoids, which are 3-dimensional multicellular in vitro tissue constructs that fundamentally imitate in vivo organs, have been developed as alternative systems to study various aspects of organs. Herein, we review recent studies on the application of organoids in disease modeling, with a focus on intestine, lung, and tonsil organoids. These 3 organoids have been of utmost interest to researchers since their initial development. Most importantly, organoids are novel experimental models that can simulate in vivo organs and can therefore replace or support existing in vitro and in vivo models.","PeriodicalId":100198,"journal":{"name":"Brain Organoid and Systems Neuroscience Journal","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75351411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent developments in organoid technology have made it possible to study how hiPSC-derived CMs interact together, and this culture system mimics the tissue environment and behavior of the cardiac cells in our body. However, the similarities and differences between conventional 2-dimensional (2D) culture and 3-dimensional (3D) organoid culture systems for CM differentiation have been incompletely elucidated. To study how the individual microenvironment formed by each culture system affects the properties of CMs differentiated from hiPSCs, we conducted a comparative study between 2D monolayer and direct 3D cardiac organoid (hiCO) differentiation from hiPSCs throughout the sequential differentiation stages. Although identical differentiation cues were applied to hiPSCs, the 3D differentiation system strongly exhibited higher mesoderm commitment and cardiac induction than 2D monolayer differentiation. In the late stage of differentiation, the 3D hiCOs showed a higher frequency of a mature myofibrillar isoform switching in sarcomere structure of differentiated CMs than was observed in monolayer culture, although over 94% of cardiac troponin T-positive cells resulted at the end point of differentiation in both systems. Furthermore, the accelerated structural maturation in 3D hiCOs resulted in increased expression of cardiac-specific ion channel genes and Ca2+ transient properties, with a high signal amplitude and rapid contractility. The present study provides details surrounding the 2D and 3D culture methods for CM differentiation from iPSCs, and focuses on 3D cell culture as an improved strategy for approaching and applying cardiac maturation.","PeriodicalId":100198,"journal":{"name":"Brain Organoid and Systems Neuroscience Journal","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79147077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Organoids are a recent breakthrough in 3-dimensional (3D) in vitro tissue engineering that better reflect the physiological, morphological, and functional properties of in vivo organs (e.g., brain, heart, kidney, lung, and liver). Consequently, organoids are extensively used in various impactful biomedical applications including organ development, disease modeling, and clinical drug testing. However, organoid technology still has several limitations, including low reproducibility, vascularization, limited nutrient uptake and distribution (affecting the level of organoid maturation), lack of standardization, and intra-clonal variability. Efforts have been made to overcome these shortcomings of organoid culture. Microfluidic technology has successfully facilitated the establishment of organoid-on-a-chip systems, which effectively improve the structural and physiological features of organoids in a controlled manner. This review discusses the recent advances and developments in organoid-on-a-chip technology. We hope that this study will motivate researchers to explore the possible engagement between microfluidic devices and self-assembled 3D cell cultures to leverage the enhanced quality of organoids, which will have favorable impacts on future tissue regeneration and regenerative therapies.","PeriodicalId":100198,"journal":{"name":"Brain Organoid and Systems Neuroscience Journal","volume":"79 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76090375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
