Summary (written by the submitters)

Rationale: Bronchopulmonary Dysplasia (BPD) arises from disrupted lung development after preterm birth and produces structural deficits at every level of the respiratory tree. Lower airway disease is emerging as a clinically significant BPD phenotype with increased mortality, yet the molecular mechanisms whereby preterm birth disrupts airway development remain poorly defined.

Objectives: To develop a human model of lower airway disease following preterm birth and to define a molecular endotype of evolving BPD (eBPD) at baseline and in response to injury. Methods: An ex vivo organotypic Airway Epithelial Cell (AEC) model was combined with well-characterized pathologic and transcriptomic patient samples for quantitative immunohistochemistry and RNA sequencing analyses. Measurements and Main Results: Compared to AECs from healthy controls, eBPD-derived AECs exhibited reduced proliferation, impaired differentiation to ciliated epithelium, and expansion of a vimentin-positive population with a transcriptional profile associated with impaired AEC differentiation. Following hyperoxia exposure, eBPD-derived AECs mounted a robust vimentin response ex vivo, paralleling increased vimentin expression observed in airway cells from lung tissue from human infants with BPD. Conclusions: Using an organotypic model of neonatal airway differentiation, we demonstrate eBPD is associated with impaired AEC differentiation, increased vimentin-expression and concomitant loss of ciliated cells, and an exaggerated vimentin response to hyperoxic injury. These findings mimic the effects of prematurity in airway cells in human patients. These data support a mechanism whereby hyperoxia leads to impaired epithelial differentiation and associated lower airway dysfunction in BPD and inform future mechanistic studies interrogating the role of intermediate filaments in evolving BPD.

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1419759 and SRA study SRP675209. Searching any of these in the dataset finder brings you back here.

Study design

12 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 12 sample titles: 12 distinct titles with little repetition. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
