Automated segmentation and evaluation algorithms have been demonstrated to enhance the simplicity and translational utility of organoid technology. However, there is a pressing need for the development of complex organoids that possess epithelium environmental elements, dense regional cell aggregation, and intraorganoid morphologies. Nevertheless, there has been limited progress, including both the construction of data sets and the development of algorithms, in the use of user-friendly microscopy to address such complex organoids. In this study, a data set of bright-field and living cell fluorescence images in paired forms and with temporal variance was constructed using droplet-engineered lung organoids. Additionally, a large model-based algorithm was developed. Both the organoid contours and intraorganoid morphologies were included in the data set, and their physical parameters were included and screened to form multiplex digital markers for organoid evaluation. The algorithm has been demonstrated to outperform existing methods and is therefore suitable for the evaluation of complex organoids. It is expected that the algorithm will facilitate the successful demonstration of AI in organoid evaluation and decision-making regarding their status.

Small-cell lung cancer (SCLC), an aggressive neuroendocrine tumor strongly associated with exposure to tobacco carcinogens, is characterized by early dissemination and dismal prognosis with a five-year overall survival of less than 7%. High-frequency gain-of-function mutations in oncogenes are rarely reported, and intratumor heterogeneity (ITH) remains to be determined in SCLC. Here, via multiomics analyses of 314 SCLCs, we found that the ASCL1/MKI67 and ASCL1/CRIP2 clusters accounted for 74.

Pancreatic ductal adenocarcinoma (PDAC) remains a highly aggressive malignancy with poor therapeutic outcomes due to its desmoplastic tumor microenvironment (TME), hindering drug and activated immune cell penetration. Cancer-associated fibroblasts (CAFs) are central in supporting tumor growth and forming a protective stroma. We propose a novel dual-therapy targeting the Hippo pathway and histone deacetylation, both involved in tumor progression, resistance, and stromal interactions, to overcome PDAC therapeutic resistance.

Accurate identification of tumor-specific markers is vital for developing chimeric antigen receptor (CAR)-based therapies. While cell surface antigens are seldom cancer-restricted, their post-translational modifications (PTMs), particularly aberrant carbohydrate structures, offer attractive alternatives. Among these, the sialyl-Tn (STn) antigen stands out for its prevalent presence in various epithelial tumors.

Food nutrition and safety are fundamental to the food industry, and the development of appropriate research models is crucial. Unlike traditional animal models, the innovative organoid/organ-on-a-chip model possess distinct human-like characteristics and genomic stability, which have garnered significant attention in food research. In this review, we conduct a comparative analysis between organoids and traditional animal and 2D cell models.

Enterohemorrhagic (EHEC), a pathotype within the Shiga toxin-producing (STEC) group, is a major etiological agent of severe gastrointestinal illness and life-threatening sequelae, including hemolytic uremic syndrome. Although insights into EHEC pathogenesis have been gained through traditional 2D cell culture systems and animal models, these platforms are limited in their ability to recapitulate human-specific physiological responses and tissue-level interactions. Recent progress in three-dimensional (3D) cell culture systems, such as spheroids, organoids, and organ-on-a-chip (OoC) technologies, has enabled more physiologically relevant models for investigating host-pathogen dynamics.
