Hyperoxia in FGF10 knock-down mice [AEC II cells]

ABSTRACT: Our previous data obtained by using immunohistochemistry showed, that Fgf10+/- (50% Fgf10 expression compared to WT) in hyperoxic condition at postnatal day 3 (P3) compared to WT has less vessel count in the lung and less muscularization of small capillaries in the lung. Furthermore, Fgf10+/- showed a drastic increase in mortality upon hyperoxic lung injury. Main question to be answer by this experiment is as followed: Does AEC II from Fgf10+/- mice in normoxia show different expression profiles at P3 compared to AEC II from WT? To adress this question we harvest lungs at P3 from WT and Fgf10+/- . For this the mice were sacrificed by Ketamin/ Dormitor ip, lungs were perfused transcardiac with PBS and directly frozen in liquid nitrogen.

Transcriptome analysis of influenza infected GFP+ AEC compared to bystander GFP- AEC

Project description:A GFP-expressing recombinant A/Puerto Rico/8/1934 influenza virus was used to infect C57BL/6 wild type mice and on day 3 post infection, lung alveolar epithelial cells (AEC) were isolated and sorted based on GFP expression. GFP+ AEC represent the infected AEC and GFP- AEC represent the bystander AEC. AEC were also sorted from uninfected mice to serve as controls.

Alveolar epithelial cells are competent producers of interstitial extracellular matrix with disease relevant plasticity in a human in vitro 3D model

Project description:The structure of alveoli is critical for proper lung function, the extracellular matrix (ECM) that forms these delicate structures need to be maintained throughout life, when this fails, patients suffer from conditions such as emphysema or lung fibrosis. The alveolar walls are lined by alveolar epithelial cells (AEC), and we herein set out to examine their potential to contribute to ECM remodeling in a human three-dimensional in vitro model based on human lung ECM. Cryopreserved type 2 AEC (AEC2) isolated from healthy lungs and lungs of patients with chronic obstructive pulmonary disease (COPD) were cultured in decellularized human lung slices over a period of 13 days. AEC2 from healthy lungs were treated with transforming growth factor ß1 (TGF-ß1) to evaluate the plasticity of their ECM production. Evaluation of phenotypic markers and expression of matrisome genes and proteins were performed by RNA-sequencing, mass spectrometry and immunohistochemistry. AEC2 in our model displayed an AEC marker profile similar to freshly isolated AEC2. COPD-derived AEC2 retained expression of known disease markers such as HLA-A throughout the culture period. AEC2 matrisome expression was found not to be limited to basement membrane components but included a complex set of structural proteins found in interstitial ECM. With TGF-ß1 stimuli, AEC2 showed a change in ECM production resembling what have previously been documented in mesenchymal cells, without loss of AEC marker expression. A previously unexplored potential of AEC to directly contribute to ECM turnover is revealed, motivating a re-evaluation of the role of AEC2 in pathological lung remodeling.

Disrupted transcripitonal network in ΔNp63 AEC tissue model [gene expression]

Project description:The transcriptional basis for disrupted epidermal differentiation arising from TP63 AEC mutations remains to be elucidated. Here we present an organotypic model of AEC dysfunction that phenocopies differentiation defects observed in AEC patient skin. Transcriptional analysis of model AEC tissue revealed impaired induction of differentiation regulators, including OVOL1, GRHL3, KLF4, PRDM1 and ZNF750. Genome wide binding analyses of TP63 during epidermal differentiation showed direct binding of OVOL1, GRHL3, and ZNF750 promoters suggesting AEC mutants prevent normal activation of these targets by direct transcriptional interference. Remarkably, exogenous ZNF750 restores impaired epidermal differentiation caused by AEC mutation. Thus, repression of ZNF750 is central to disrupted epidermal differentiation in model AEC tissue. Gene expression analysis: To establish a differentiation signature for primary human keratinocytes, with p63i-depleted, and ΔNp63α AEC mutants overexpressed, total RNA was isolated in biologic duplicate from cells in different conditions and hybridized to Affymetrix HG-U133 2.0 Plus arrays.
