Assessment of an engineered endothelium via single-photon emission computed tomography.
Article in Biotechnology and bioengineering, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The clinical translation of cell-based therapeutics often requires highly sensitive, non-invasive imaging tools to assess cell function and distribution in vivo. The objective of this research was to determine whether human Sodium-Iodide Symporter (hNIS) ectopic expression in endothelial cells (ECs) in combination with single-photon emission computed tomography (SPECT) is a feasible approach to non-invasively monitor the presence and viability of an engineered endothelium on expanded polytetrafluoroethylene (ePTFE). Human umbilical vein endothelial cells (HUVECs) were transduced with pLL3.7-hNIS via lentivirus with multiplicity of infection (MOI) of 0, 2, 5, and 10 (n = 4). Ectopic expression of hNIS in HUVECs via optimized lentiviral transduction (MOI 5) enabled cell uptake of a radioisotope that can be detected by SPECT without affecting endothelial cell viability, oxidative stress, or antithrombogenic functions. The viability and distribution of an engineered endothelium grown on ePTFE coated with the biodegradable elastomer poly(1, 8 octamethylene citrate) (POC) and exposed to fluid flow was successfully monitored non-invasively by SPECT. We report the feasibility of a non-invasive, highly sensitive and functional assessment of an engineered endothelium on ePTFE using a combination of SPECT and X-ray computed tomography (SPECT/CT) imaging and hNIS ectopic expression in ECs. This technology potentially allows for the non-invasive assessment of transplanted living cells in vascular conduits. Biotechnol. Bioeng. 2017;114: 2371-2377. © 2017 Wiley Periodicals, Inc.
