Blood-derived smooth muscle cells as a target for gene delivery.
Article in Journal of vascular surgery, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveTo examine the feasibility of using blood-derived smooth muscle cells (BD-SMCs) as a target for to deliver therapeutic proteins. MATERIALS AND
methodsMononuclear cells (MNC) were isolated from peripheral blood. The outgrowth colonies from MNC culture were differentiated into BD-SMCs in media containing platelet-derived growth factor BB. Phenotypic characterization of BD-SMCs was assessed by immunocytochemistry. Cell proliferation, gene transfer efficiency with a retroviral vector, apoptosis, and the biological activity of the transduced gene product from the BD-SMCs were evaluated in vitro and in vivo in comparison with vascular derived SMC (VSMCs).
resultsBD-SMCs stained positive for SMC markers. No significant difference was observed between BD-SMCs and VSMCs in cell proliferation, migration, adhesiveness, and gene transfer efficiency. After BD-SMCs were transduced with a retroviral vector carrying the secreted alkaline phosphatase gene (SEAP), 174 +/- 50 mug biologically active SEAP was produced per 10(6) cells over 24 hours. After injecting 5 x 10(6) cells expressing SEAP intravenously into rabbits, SEAP concentration increased significantly in the circulation from 0.14 +/- 0.04 mug/ml to 2.34 +/- 0.16 mug/ml 3 days after cell injection (P < .01, n = 3). Circulating levels of SEAP decreased to 1.76 mug /ml 1 week later and remained at this level up to 8 weeks, then declined to pre-cell injection level at 12 weeks. VSMC in vivo gene expression data were equivalent.
conclusionBD-SMCs have similar characteristics to mature VSMCs and can be used as a novel target for gene transfer to deliver a therapeutic protein.
