Upscaling: efficient generation of human lung organoids from induced pluripotent stem cells using a stirring bioreactor.
Article in Frontiers in bioengineering and biotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Introduction: Human induced pluripotent stem cells (iPSCs) can be successfully differentiated into complex (three-dimensional) lung spheroids or organoids and have thus proven to be promising in vitro tools that provide a robust system for simulating lung disease and modeling drug response. We previously described a very simple and practical protocol for producing iPSC-derived lung organoids (iPSC-LuOrgs) in ultra-low attachment plates without relying on a gel-like extracellular matrix. Methods: Here, we produced these organoids in a stirred-tank bioreactor equipped with a unique membrane stirrer and compared this type of up-scaled and more automated cultivation with the manual variant. Detailed morphological and molecular analyses, including single-cell RNA sequencing, of the differently generated LuOrgs were performed. Results: Just like in the manual variant, using the bioreactor morphologically comparable lung organoids could be obtained that showed a very similar cellular composition. This type of generation can also be considered as animal-component-free production. Discussion: These freely floating LuOrgs are now available in large numbers for the investigation of, for example, cancer therapy approaches as a new and patient-oriented in vitro platform.
