Identification of hepatocyte-primed cholangiocytes in the homeostatic liver by in vivo lentiviral gene transfer to mice and non-human primates.
Article in Cell reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Liver regeneration is supported by hepatocytes and, in certain conditions, biliary epithelial cells (BECs). BECs are facultative liver stem cells that form organoids in culture and engraft in damaged livers. However, BEC heterogeneity in the homeostatic liver remains to be fully elucidated. Here, we exploit systemic lentiviral vector (LV) administration to achieve efficient and lifelong gene transfer to BECs in mice. We find that LV-marked BECs retain organoid formation potential and predominantly respond to liver damage; however, they are less clonogenic and display a hepatocyte-primed transcriptome compared to untransduced BECs. We thus identify a BEC subset committed to hepatocyte lineage in the absence of liver damage, characterized by a transcriptional network orchestrated by hepatocyte nuclear factor 4α. We also report in vivo targeting of such BECs in non-human primates. This work highlights intrinsic BEC heterogeneity and that in vivo LV gene transfer to the liver may persist following BEC-mediated repair of hepatic damage.
