Improved functionality of hepatic spheroids cultured in acoustic levitation compared to existing 2D and 3D models.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Hepatic spheroids are of high interest in basic research, drug discovery and cell therapy. Existing methods for spheroid culture present advantages and drawbacks. An alternative technology is explored: the hepatic spheroid formation and culture in an acoustofluidic chip, using HepaRG cell line. Spheroid formation and morphology, cell viability, genetic stability, and hepatic functions are analyzed after 6 days of culture in acoustic levitation. They are compared to 2D culture and non-levitated 3D cultures. Sizes of the 25 spheroids created in a single acoustofluidic microphysiological system are homogeneous. The acoustic parameters in our system do not induce cell mortality nor DNA damage. Spheroids are cohesive and dense. From a functional point of view, hepatic spheroids obtained by acoustic levitation exhibit polarity markers, secrete albumin and express hepatic genes at higher levels compared to 2D and low attachment 3D cultures. In conclusion, this microphysiological system proves not only to be suitable for long-term culture of hepatic spheroids, but also to favor differentiation and functionality within 6 days of culture.
