In silico modeling of anterior foregut endoderm differentiation towards lung epithelial progenitors
NPJ Systems Biology and Applications 2026 Jan
Abstract
Directed differentiation of human induced pluripotent stem cells (iPSCs) into anterior foregut endoderm (AFE) and lung progenitors (LPs) has wide-ranging implications for lung developmental biology, disease modeling, and regenerative medicine. We expand on a previously developed mathematical modeling framework and apply it to the directed differentiation of AFE into LPs. A model-based approach guides experimental design, followed by a multistage model inference process: maximum likelihood estimation based on in vitro data and identifiability analyses to eliminate unidentifiable candidates, thereby guiding model selection. To the authors’ knowledge, this is the first mathematical model of the population dynamics of directed differentiation of AFE into LPs. The model suggests that the overall dynamics are primarily driven by AFE proliferation and differentiation into LPs. In silico experiments predict that daily media change nearly doubles LP yields compared to cultures without media replenishment. Moreover, the model suggests that higher split ratios on day 10 enhance yield per input cell, a measure of differentiation efficiency, by 26%. This work provides a blueprint for refining iPSC-based lung lineage differentiation protocols by combining empirical data and mathematical modeling.
CRISPR-engineered human lung organoids with a biomolecular condensate reporter enable mechanistic toxicity monitoring
Materials Today Bio 2026 Feb
Abstract
Understanding how chemical stress perturbs human lung physiology requires models that capture dynamic molecular responses in real time. Here, we established a CRISPR/Cas9-engineered human induced pluripotent stem cell (hiPSC)-derived lung organoid expressing endogenous G3BP1–mCherry, enabling live, non-destructive visualization of stress granule (SG) formation under toxicant exposure. The organoids recapitulated airway and alveolar epithelial diversity and displayed lamellar body-like ultrastructures, indicating advanced maturation. Time-lapse imaging revealed rapid and reversible SG dynamics across chemically distinct stressors, while cytotoxicity assays showed that these organoids are significantly more sensitive than conventional 2D or cancer-derived lung models. Importantly, SG dynamics were linked to exposure duration–dependent changes in epithelial barrier integrity, indicating that SG formation precedes overt epithelial injury and serves as an early indicator of toxicant-induced cellular stress. Integration with high-content screening enabled quantitative, image-based analysis of cellular stress phenotypes, greatly enhancing throughput and mechanistic insight, thereby provided next-generation New Approach Methodologies for lung toxicity assessment. Together, this hiPSC-derived lung organoid SG reporter platform links early molecular stress adaptation to tissue-level responses, offering a predictive and mechanistically informative framework for human-relevant lung toxicity evaluation.
Filovirus infection disrupts epithelial barrier function and ion transport in human iPSC-derived gut organoids
PLOS Pathogens 2025 Nov
Abstract
Gastrointestinal (GI) dysfunction, characterized by severe diarrhea and dehydration, is a central contributor to morbidity and mortality in filovirus disease in patients, yet the role of the epithelium in this clinical outcome remains poorly defined. Here, we employ induced pluripotent stem cell (iPSC)-derived human intestinal (HIOs) and colonic organoids (HCOs) to model Ebola virus (EBOV) and Marburg virus (MARV) infection. These organoids are permissive to filovirus infection and support viral replication. Bulk RNA sequencing revealed distinct intestinal and colonic epithelial responses, including apical and junctional disruption and a delayed virus-specific induction of interferon-stimulated genes. Moreover, infection impaired adenylate cyclase signaling and CFTR-mediated ion transport, providing mechanistic insight into virus-induced secretory diarrhea. This platform recapitulates key features of human GI pathology in filoviral disease and serves as a powerful system to dissect host-pathogen interactions and identify therapeutic targets. Author summaryEbola virus (EBOV) and Marburg virus (MARV) are among the most lethal viruses known. Infection with these viruses leads to severe disease and death. One of their most harmful effects is damage to the gastrointestinal tract, causing intense diarrhea and life-threatening dehydration. Yet, how these viruses affect the gut remains poorly understood. In this study, we used human mini-guts—small, three-dimensional tissues grown from stem cells that mimic the human intestinal and colonic epithelium—to investigate how these viruses interact with gut epithelial cells. We found that both EBOV and MARV infect and replicate in these tissues, disrupt key barrier structures, and interfere with the cells’ ability to regulate fluid secretion. These effects mirror the severe symptoms seen in patients. Our study provides new insight into how EBOV and MARV damage the gut and identifies specific cellular pathways that may be targeted for treatment. This research not only improves our understanding of EBOV and MARV infections but also offers new infection platforms for testing therapies aimed at protecting the gastrointestinal system during filovirus outbreaks.
