Cell culture differentiation and proliferation conditions influence the in vitro regeneration of the human airway epithelium

ABSTRACT: The human airway mucociliary epithelium can be recapitulatedin vitro using primary cells cultured in an Air-Liquid Interface (ALI), a reliable surrogate to perform pathophysiological studies. As tremendous variations exist between media used for ALI-cultured human airway epithelial cells, our study aimed to evaluate at a single-cell level the impact of several media (e.g. BEGMTM, PneumaCultTM, “Half&Half” and “Clancy”) on cell type distribution. Our work revealed the impact of these media on cell composition, gene expression profile, cell signaling or epithelial shape. We also established that proliferation in PneumaCultTM-Ex Plus favored secretory cells fate, showing the key influence of proliferation media on late differentiation epithelial characteristics. Altogether, our data offer a comprehensive repertoire for evaluating the effects of culture conditions on airway epithelial differentiation and will help to choose the most relevant medium according to the phenomenon to be investigated such as cilia or mucus biology or viral infection. We detail useful parameters that should be explored to document airway epithelial cell fate and shaping.

MicroRNA signature during the time course of regeneration of the human airway mucociliary epithelium

Project description:The regeneration of the airway mucociliary epithelium involves several sequential events including migration, proliferation, polarization and final differentiation (i.e ciliogenesis). The airway mucociliary epithelium is consituted of three main cell types : ciliated cells, secretory cells and basal cells. We used microRNA microrrays to investigate the signature of microRNA during the four step of regeneration of the airway epithelium. Four time points (ALI-D0, ALI-D7, ALI-D14, ALI-D21) of regeneration of the airway epithelium for 3 donors.

Global transcriptomic analyses of pluripotent stem cell-derived airway epithelial cells at 1 and 3 days after infection with SARS-CoV-2

Project description:We performed transcriptomic profiling of human iPSC-derived airway epithelial cells after infection with SARS-Co-V2. Using a recently described protocol to first generate airway basal cells from iPSCs and sunsequently differentiate those basal cells (iBCs) into a mucociliary epithelium in air-liquid interface culture. In this experiment we generated airway epithelial cultures from two different iPSC lines ("BU3 NGPT" and "1566"). In stage 6 of this protocol (>D45) iBCs are identified and purified by sorting on NGFR+ cells, and purified cells are expanded and differentiated on Transwells in dual-SMAD inhibition media then transitioned to ALI media when >80% confluent. Apical chamber media is removed to initiate ALI to recapitulate a physiologically-relevant environment and stimulate differentiation. After 14 days, iBCs form a pseudostratified airway epithelium that displays morphologic, molecular, and functional similarities to primary human airway epithelial cells and is comprised of the major airway cell types of multi-ciliated, secretory, and basal cellscomposed of the major airway epithelial cell types, that is permissive to SARS-CoV-2 infection. We studied the response of these iPSC-derived airway epithelial cells to SARS-CoV-2 infection using RNA-Sequencing 1 and 3 days post infection (DPI).

Transcriptome analysis during the time course of regeneration of the human airway mucociliary epithelium

Project description:The regeneration of the airway mucociliary epithelium involves several sequential events including migration, proliferation, polarization and final differentiation (i.e ciliogenesis). We used microarrays to detail the global programme of gene expression that occurs during regeneration and ciliogenesis of the human airway mucociliary epithelium. The four time points of regeneration of the airway epithelium (ALI-D0 which corresponds to the end of proliferation step; ALI-D7 which corresponds to the polarization step; ALI-D14 which corresponds to the onset of ciliogenesis and ALI-D21 corresponding to the terminal differentiation step) for RNA extraction and hybridization on Affymetrix microarrays.

Do Airway Epithelium Air-liquid Cultures Represent the In Vivo Airway Epithelium Transcriptome?

Project description:Human airway epithelial cells cultured in vitro at air-liquid interface (ALI) form a pseudostratified epithelium that forms tight junctions and cilia, and produces mucin, and are widely used as a model of differentiation, injury, and repair. To assess how closely the transcriptome of ALI epithelium matches that of in vivo airway epithelial cells, we used microarrays to compare the transcriptome of human large airway epithelial cells cultured at ALI with the transcriptome of large airway epithelium obtained via bronchoscopy and brushing. Gene expression profiling showed global gene expression correlated well between ALI cells and brushed cells, but there were some differences. Gene expression patterns mirrored differences in proportions of cell types (ALI have higher percentages of basal cells, brushed cells have higher percentages of ciliated cells), with ALI cells expressing higher levels of basal cell-related genes and brushed cells expressing higher levels of cilia-related genes. Pathway analysis showed ALI cells had increased expression of cell cycle and proliferation genes, while brushed cells had increased expression of cytoskeletal organization and humoral immune response genes. Overall, ALI cells are a good representation of the in vivo airway epithelial transcriptome, but for some biologic questions, the differences in the in vitro vs in vivo environments need to be considered. Affymetrix arrays were used to assess the gene expression of large airway cells cultured in vitro at air-liquid interface (12 samples) and large airway epithelial cells obtained by fiberoptic bronchoscopy of 20 healthy nonsmokers. *** Air-liquid interface Samples not provided in this Series. ***

Transcription profiling of human airway epithelial cells sampled at multiple time points to examine mucociliary differentiation

Project description:Microarray analysis was performed to identify transcriptional changes that occur during mucociliary differentiation of human primary bronchial epithelial cells cultured at an air-liquid interface (ALI). Experiment Overall Design: Cells from three different donors were cultured and collected at 11 different time points from day 0 to day 28 of ALI culture.

Changes in microRNA and mRNA expression with differentiation of human bronchial epithelial cells [mRNA]

Project description:Normal human bronchial epithelial (NHBE) cells cultured in an air-liquid interface (ALI) system form a polarized, pseudostratified epithelium composed of basal, ciliated and goblet cells that closely resemble the in vivo airway epithelium structure. ALI cultures of NHBE cells provide a unique in vitro system to investigate airway epithelial biology, including developmental, structural and physiologic aspects. In this study, we wanted to investigate mRNA expression patterns during airway epithelium differentiation. By using microarrays, we studied the changes in expression of mRNAs in normal human bronchial epithelial cells as they differentiate from an undifferentiated monolayer to a differentiated pseudostratified epithelium after 28 days of air-liquid interface (ALI) culture, when epithelial cells differentially express basal, ciliated and goblet cell markers. Normal human bronchial epithelial cells were cultured in an air-liquid interface (ALI) system and harvested at three different time-points: subconfluent, confluent and day 28 of ALI. Samples were processed for total RNA extraction and hybridization on Affymetrix microarrays. All the experiments were performed by triplicate.

Direct exposure to SARS-CoV-2 and cigarette smoke increases infection severity and alters the stem cell-derived airway repair response

Project description:To study the effect of cigarette smoke exposure on Sars-Cov2 infection, we directly exposed mucociliary air-liquid interface (ALI) cultures derived from primary human nonsmoker airway basal stem cells (ABSCs) to short term cigarette smoke and infected them with live SARS-CoV-2. We set out to examine the underlying mechanisms governing the increased susceptibility of cigarette smoke exposed ALI cultures to SARS-CoV-2 infection by usingle cell profiling of the cultures, which showed that interferon response genes were induced in SARS-CoV-2 infected airway epithelial cells in ALI cultures but smoking exposure together with SARS-CoV-2 infection reduced the interferon response.
