Activation of canonical Wnt signaling is required for efficient direct reprogramming into human hepatic progenitor cells.
Article in Stem cell reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Direct reprogramming is a technique for elucidating the mechanisms that control cell-fate decisions and holds promise as a therapeutic strategy. We previously showed that a specific combination of three transcription factors (FOXA3, HNF1A, and HNF6) can induce direct reprogramming of human umbilical vein endothelial cells (HUVECs) into human induced hepatic progenitor cells (hiHepPCs). However, low reprogramming efficiency limits their application in research and therapy. Here, we show that activation of the canonical Wnt signaling pathway increases the reprogramming efficiency of HUVECs to hiHepPCs by rapidly inducing chromatin remodeling and gene expression changes in the transduced HUVECs. Moreover, endogenous Wnt activation, mainly mediated by WNT2B, is required for the initiation of direct reprogramming from HUVECs to hiHepPCs. Wnt activation that allows rapid induction of hiHepPCs enables efficient production of a large amount of hiHepPCs, which is an advantage in research and clinical applications using hiHepPCs and their descendants.
