Open chromatin and transcriptome analysis of iPSCs differentiated into lung epithelium at air-liquid interface reveals key transcriptional drivers and processes (RNA-seq data)

Project description:The availability of robust protocols to differentiate induced pluripotent stem cells (iPSCs) into many human cell lineages has transformed research into the origins of human disease. The efficacy of differentiating iPSCs into specific cellular models is influenced by many factors including both intrinsic and extrinsic features. Among the most challenging models is the generation of human bronchial epithelium at air-liquid interface (HBE-ALI), which is the gold standard for many studies of respiratory diseases including cystic fibrosis. Here we perform open chromatin mapping by ATAC-seq and transcriptomics by RNA-seq in parallel, to define the functional genomics of key stages of the iPSC to HBE-ALI differentiation. Within open chromatin peaks the overrepresented motifs include the architectural protein CTCF at all stages, while motifs for the FOXA and GATA pioneer factors families are only seen at early stages, and those regulating key airway epithelial functions, such as EHF, are limited to later stages. The RNA-seq data illustrate dynamic pathways during the iPSC to HBE-ALI differentiation, and also the marked functional divergence of different iPSC lines at the ALI stages of differentiation. Moreover, a comparison of iPSC-derived and lung donor-derived HBE-ALI cultures reveals substantial differences between these models.

Air-Liquid-Interface Differentiated Human Nose Epithelium: A Robust Primary Tissue Culture Model of SARS-CoV-2 Infection.

Project description:The global urgency to uncover medical countermeasures to combat the COVID-19 pandemic caused by the severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) has revealed an unmet need for robust tissue culture models that faithfully recapitulate key features of human tissues and disease. Infection of the nose is considered the dominant initial site for SARS-CoV-2 infection and models that replicate this entry portal offer the greatest potential for examining and demonstrating the effectiveness of countermeasures designed to prevent or manage this highly communicable disease. Here, we test an air-liquid-interface (ALI) differentiated human nasal epithelium (HNE) culture system as a model of authentic SARS-CoV-2 infection. Progenitor cells (basal cells) were isolated from nasal turbinate brushings, expanded under conditionally reprogrammed cell (CRC) culture conditions and differentiated at ALI. Differentiated cells were inoculated with different SARS-CoV-2 clinical isolates. Infectious virus release into apical washes was determined by TCID50, while infected cells were visualized by immunofluorescence and confocal microscopy. We demonstrate robust, reproducible SARS-CoV-2 infection of ALI-HNE established from different donors. Viral entry and release occurred from the apical surface, and infection was primarily observed in ciliated cells. In contrast to the ancestral clinical isolate, the Delta variant caused considerable cell damage. Successful establishment of ALI-HNE is donor dependent. ALI-HNE recapitulate key features of human SARS-CoV-2 infection of the nose and can serve as a pre-clinical model without the need for invasive collection of human respiratory tissue samples.

Modeling dry eye with an air-liquid interface in corneal epithelium-on-a-chip

Project description:Dry eye syndrome (DES) is a complex ocular condition characterized by an unstable tear film and inadequate tear production, leading to tissue damage. Despite its common occurrence, there is currently no comprehensive in vitro model that accurately reproduce the cellular characteristics of DES. Here we modified a corneal epithelium-on-a-chip (CEpOC) model to recapitulate DES by subjecting HCE-T human corneal epithelial cells to an air-liquid (AL) interface stimulus. We then assessed the effects of AL stimulation both in the presence and absence of diclofenac (DCF). Transcriptomic analysis revealed distinct gene expression changes in response to AL and AL_DCF, affecting pathways related to development, epithelial structure, inflammation, and extracellular matrix remodeling. Both treatments upregulated PIEZO2, linked to corneal damage signaling, while downregulating OCLN, involved in cell-cell junctions. They increased the expression of inflammatory genes (e.g., IL6) and reduced mucin production genes (e.g., MUC16), reflecting dry eye characteristics. TGFB1, crucial for corneal wound healing, was slightly downregulated in AL_DCF, potentially affecting wound healing processes rather than reducing inflammation by DCF. Metabolomic analysis showed increased secretion of metabolites associated with cell damage and inflammation (e.g., methyl-2-oxovaleric acid, 3-methyl-2-oxobutanoic acid, lauroyl-carnitine) in response to AL and even more with AL_DCF, indicating a shift in cellular metabolism. This study showcases the utilization of AL stimulus within the CEpOC as a comprehensive approach to faithfully reproduce the cellular characteristics of DES.

Human ileum stem cell differentiation by air-liquid interface

Project description:Despite major advances with embryonic and induced pluripotent stem cells or lineage-committed, p63-expressing stem cells of stratified epithelia, we know less about the indigenous stem cells of the gastrointestinal tract, pancreas, liver, and other columnar epithelia which collectively resist cloning in their elemental states. Here we demonstrate the cloning of highly immature epithelial stem cells from defined regions of the human intestine and colon. In this study, we have isolated ileal stem cells and performed air-liquid interface method to induce differentiation of human ileal stem cells. The differentiated structure showed villi-like epithelia which contains enterocytes, goblet cells, endocrine cells and paneth cells.

scRNAseq of human primary nasal epithelium differentiated at air-liquid interface exposed to SARS-CoV2

Project description:The nasal epithelium is a plausible entry point for SARS-CoV-2, a site of pathogenesis and transmission, and may initiate the host response to SARS-CoV-2. Antiviral interferon responses are critical to outcome of SARS-CoV-2. Yet little is known about the interaction between SARS-CoV-2 and innate immunity in this tissue. Here we applied single-cell RNA sequencing and proteomics to a primary cell model of human primary nasal epithelium differentiated at air-liquid interface.
