Unveiling critical signaling pathways in the murine salivary gland and the role of midkine.
Article in iScience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Salivary gland (SG) development is a complex process involving coordinated signaling between epithelial and stromal cell populations. While some growth drivers and branching mechanisms are known, many intercellular communication pathways that underpin embryonic SG morphogenesis remain unidentified. We leveraged single cell RNA-sequencing datasets, from murine submandibular salivary glands at three embryonic stages to identify critical signaling networks. Using CellChat, we mapped global ligand-receptor interactions among different cell populations revealing an evolving signaling landscape during gland maturation. Our analysis highlighted both well-established and understudied pathways, including midkine (MDK) signaling. Functional experiments using embryonic SG explants demonstrated that MDK regulates branching morphogenesis via Rho-associated coiled coil containing protein kinase 1 (Rock1) signaling. Additionally, the key lineage driving transcription factor p63 was shown to act as primary mediator of the MDK/Rock1 axis. These findings uncover a comprehensive signaling code that guides SG development and offers new targets for follow-up studies into SG regeneration.
