Controlled delivery of fibroblast growth factor-9 from biodegradable poly(ester amide) fibers for building functional neovasculature.
Article in Pharmaceutical research, 2014. 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
purposeFor building functional vasculature, controlled delivery of fibroblast growth factor-9 (FGF9) from electrospun fibers is an appealing strategy to overcome challenges associated with its short half-life. FGF9 sustained delivery could potentially drive muscularization of angiogenic sprouts and help regenerate stable functional neovasculature in ischemic vascular disease patients.
methodsElectrospinning parameters of FGF9-loaded poly(ester amide) (PEA) fibers have been optimized, using blend and emulsion electrospinning techniques. In vitro PEA matrix degradation, biocompatibility, FGF9 release kinetics, and bioactivity of the released FGF9 were evaluated. qPCR was employed to evaluate platelet-derived growth factor receptor-β (PDGFRβ) gene expression in NIH-3T3 fibroblasts, 10T1/2 cells, and human coronary artery smooth muscle cells cultured on PEA fibers at different FGF9 concentrations.
resultsLoaded PEA fibers exhibited controlled release of FGF9 over 28 days with limited burst effect while preserving FGF9 bioactivity. FGF9-loaded and unloaded electrospun fibers were found to support the proliferation of fibroblasts for five days even in serum-depleted conditions. Cells cultured on FGF9-supplemented PEA mats resulted in upregulation of PDGFRβ in concentration and cell type-dependent manner.
conclusionThis study supports the premise of controlled delivery of FGF9 from PEA electrospun fibers for potential therapeutic angiogenesis applications.
