Transmyocardial Revascularization Enhances Bone Marrow Stem Cell Engraftment in Infarcted Hearts Through SCF-C-kit and SDF-1-CXCR4 Signaling Axes.
Article in Stem cell reviews and reports, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundWe investigated the roles of stem cell factor (SCF)-c-kit and stromal derived factor-1 (SDF-1)-CXCR4 signaling axes in transmyocardial revascularization (TMR)-enhanced engraftment of transplanted bone marrow stem cells (BMSCs) in infarcted hearts.
methods3 weeks after LAD ligation, female Lewis rats underwent 10-channel needle-TMR, followed by daily IV injections of 1 million male donor BMSC for 5 days, either wild type (WT) or with knockdown (K/D) of c-kit or CXCR4, accomplished via a shRNA + plasmid in a lentiviral vector (N = 6/group).
resultsIn our rat infarct model, 3 days after last BMSC injection, the number of BMSCs that homed into infarct was affected by both TMR and donor cell type, with greater BMSC engraftment with TMR and with WT BMSC (TMR, cell type, and interaction, P < 0.05). At 1 week, these differences persisted (TMR and cell type, P < 0.05). At 3 days, TMR significantly upregulated transcription of c-kit (TMR, p < 0.05), SCF (TMR and cell type, P < 0.05), CXCR4 (TMR and cell type, p < 0.05), and SDF-1 (TMR and cell type, P < 0.05). At 1 week, we saw similar declines in expression of c-kit (cell type, P < 0.05), SCF (TMR, P < 0.05), CXCR4 (TMR and cell type, P < 0.05), and SDF-1 (TMR, P < 0.05). At 1 week, TMR improved LV ejection fraction (LVEF) (N = 5) when WT BMSCs were infused, but knockdown of either c-kit or CXCR4 completely abrogated this TMR-mediated augmentation of BMSC reparative effect (TMR and cell type, P < 0.05).
conclusionsDownregulation of either c-kit or CXCR4 in BMSC decreased engraftment of circulating BMSC and inhibited reparative effects of TMR.
