Nuclear FGF2 orchestrates phase separation-mediated rDNA chromatin architecture to control BMSCs cell fate.
Article in Bone research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Ribosomal RNA (rRNA) synthesis is intricately tied to cellular growth and proliferation. Basic fibroblast growth factor (FGF2), a pivotal factor for bone marrow mesenchymal stem cells (BMSCs), can stimulates rRNA transcription, though the underlying mechanism remains unknown. Here, we demonstrate that the cytoplasm-nucleus translocation of FGF2 is determined by the stable nuclear localization motif. Meanwhile, the nuclear FGF2 regulates rRNA expression and BMSCs proliferation via phase separation. Next, through FGF2 related epigenomics and 3D genomes analysis, we identified chromatin architectures during BMSCs differentiation and aging. In the process, topologically associating domains (TADs) and chromatin loops profiling revealed the attenuated genomic interaction among proximal chromosomes 13, 14, 15, 21, and 22, where phase-separated FGF2 facilitates rDNA transcription depend on specific super-enhancers (SEs). Furthermore, we validated that FGF2 orchestrates rDNA chromatin architecture in coordination with STAT5. Together, these findings underscore the pivotal role of FGF2 in rDNA chromatin architectures, which determines BMSCs cell fate.
