A temporal single cell atlas of dynamic chromatin accessibility during murine lung maturation.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Lung maturation involves intricate cellular differentiation and structural remodeling, yet the underlying epigenetic dynamics remain poorly characterized at single-cell resolution. Here we present HTL-ATAC-seq, an ultra-high-throughput, ligation-based single-cell ATAC-seq approach. Applying HTL-ATAC-seq to mouse lung tissue across 15 continuous postnatal time points, we construct a temporal chromatin accessibility atlas of 1,185,619 nuclei, identifying 129 distinct cell subclusters and 713,987 candidate chromatin regulatory elements. Temporal analysis reveals three distinct cellular maturation stages and 12 dynamic chromatin accessibility patterns, capturing the transition from structural morphogenesis to immune maturation. We uncover distinct transcription factor regulatory patterns between alveolar type 1 and 2 cells and identify a putative Sprr1a enhancer specifically active in alveolar type 1 cells. Finally, we identify time- and cell-type-specific cis-regulatory elements associated with lung disease-related gene sets. In this work, we provide a comprehensive resource for understanding the epigenetic mechanisms underlying lung maturation and lung disease-associated regulatory programs.
