PI3K-Akt signalling regulates Scx-lineage tenocytes and Tppp3-lineage paratenon sheath cells in neonatal tendon regeneration.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
Tendon injuries are frequently occurring disorders; it is clinically important to enhance tendon regeneration and prevent functional impairment post-injury. While tendon injuries in children heal quickly with minimal scarring, those in adults heal slowly and are accompanied by fibrotic scarring. Therefore, investigating the healing mechanisms after tendon injury, and identifying the factors that regulate the inherent regenerative capacity of tendons are promising approaches to promoting tendon regeneration. Here, we identify that the PI3K-Akt signalling pathway is preferentially upregulated in injured neonatal murine Achilles tendons. Inhibition of PI3K-Akt signalling in a neonatal murine Achilles tendon rupture model decreases cell proliferation and migration in both Scx-lineage intrinsic tenocytes and Tppp3-lineage extrinsic paratenon sheath cells. Moreover, the inhibition of PI3K-Akt signalling decreases stemness and promotes mature tenogenic differentiation in both Scx- and Tppp3-lineage cells. Collectively, these results suggest that PI3K-Akt signalling plays a pivotal role in neonatal tendon regeneration.
