Pvf1-Pvr-mediated crosstalk between trachea and gut guides intestinal stem cell migration to promote gut regeneration.
Article in Nature communications, 2025. 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
In adult tissues, stem cells (SCs) reside in specialized niches, where they remain relatively stationary state until activated by injury. While migration is essential for regeneration, mechanisms guiding SCs towards injury sites remain poorly understood due to challenges in tracking them in vivo. Here, we present an experimental framework to monitor intestinal SC (ISC) movement in real time during early gut regeneration. We identify the Drosophila PDGF-VEGF-related receptor, Pvr, as a critical regulator of this process, with ISC-specific Pvr depletion strongly impairing migration and regeneration. The ligand, Pvf1, produced by gut-associated trachea after damage, serves as a guidance cue directing ISCs towards injury sites. Our work highlights a critical role of gut-trachea crosstalk in guiding ISC migration during regeneration. As neovascularization of injury sites is a key feature of tissue repair in both flies and mammals, these findings could have broader implications for regenerative processes across diverse adult tissues.
