Kinetics of the angiogenic response in lung endothelium following acute inflammatory injury with bleomycin.
Article in Experimental lung research, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
PURPOSE/
aimAngiogenesis is a central component of normal wound healing but it has not been fully characterized in lung repair following acute inflammatory injury. The current literature lacks vital information pertaining to the extent, timing, and location of this process. This information is necessary for examining mechanisms that drive normal lung repair in resolving acute inflammatory injury. The goal of our study was to formally characterize lung angiogenesis over a time course of bleomycin-induced lung injury. MATERIALS AND
methodsFemale C57BL/6 mice age 8-12 weeks were treated with a single dose of intratracheal bleomycin. Total lung endothelial cells were quantified with flow cytometry 0, 7, 14, 21, and 28 days following bleomycin administration, and endothelial cell replication was assessed using bromodeoxyuridine (BrdU) incorporation.
resultsEndothelial cell replication was maximal 14 days after bleomycin administration, while total lung endothelial cells peaked at day 21. Tissue analysis with stereology was performed to measure total lung vascular surface area in bleomycin at day 21 relative to controls and demonstrated a trend toward increased vasculature in the bleomycin group.
conclusionsAngiogenesis begins shortly after injury in the bleomycin model and leads to an expansion in the lung endothelial cell population that peaks at day 21. This study offers the first longitudinal examination of angiogenesis following acute inflammatory lung injury induced by bleomycin. Information provided in this study will be vital for further investigating mechanisms of angiogenesis in both normal and abnormal lung repair.
