1 · What the graph read from it

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.

2 · The registry

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

Poor cell engraftment in the myocardium is a limiting factor towards the use of bone marrow derived cells (BMCs) to treat myocardial infarction (MI). In order to enhance the engraftment of circulating BMCs in the myocardium following MI, we have developed in situ forming hyaluronic acid (HA) hydrogels with degradable crosslinks to sustain the release of recombinant stromal cell-derived factor-1 alpha (rSDF-1α) and HA to the injured myocardium. Both rSDF-1α and the crosslinkable HA macromer stimulate BMC chemotaxis up to 4-fold in vitro through CXCR4 and CD44 receptor signaling, respectively. Moreover, the HA macromer binds rSDF-1α with a dissociation constant of 36 ± 5 μM through electrostatic interaction. When formed into hydrogels via photoinitiated crosslinking, release of encapsulated rSDF-1α and crosslinked HA was sustained for over 7 days, and these molecules significantly increased BMC chemotaxis in vitro. When applied to the heart following experimental MI in mice, the HA gel containing rSDF-1α significantly increased the number of systemically infused BMCs in the heart by ~8.5 fold after 7 days, likely through both systemic and local effects of released molecules. We conclude that sustained release of rSDF-1α and HA from our engineered HA hydrogels enhances BMC homing to the remodeling myocardium better than delivery of rSDF-1α alone.
