Dynamic proteome profiling of differentiating human embryonic stem cells towards cardiomyocytes.
Article in Scientific reports, 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
The heart is the first functional organ to develop during embryogenesis, yet its cellular and molecular mechanisms remain incompletely understood. Proteomic studies of in vitro cardiomyogenesis have provided valuable insights, but most have focused on late-stage processes leading to cardiomyocyte specification. In this study, we profiled the proteome of differentiating cells at the mesendoderm (ME), cardiac mesoderm (CME), cardiac progenitor cell (CPC), and cardiomyocyte (C) stages using in-depth quantitative analysis via multiplexed tandem mass tag-based mass spectrometry. Unsupervised clustering of 4417 differentially expressed proteins revealed six main clusters corresponding to key biological processes at each differentiation stage. Transitional-specific proteins (TSPs), identified through pairwise comparisons of consecutive stages, were most abundant in CME, with 325 differentially expressed TSPs. Pathway enrichment analysis highlighted ferroptosis as a key process in CME specification, whereas sirtuin signaling was implicated in driving cardiomyocyte fate. This proteomic profiling expands the repertoire of potential biomarkers for each developmental stage toward cardiomyocyte specification. Overall, our stepwise proteome analysis of in vitro cardiomyocyte differentiation uncovers novel molecular mechanisms underlying heart development.
