Newly established human liver cell line: a potential cell source for the bioartificial liver in the future.
Article in Human cell, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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 use of a bioartificial liver (BAL) device strongly depends on the development of human liver cell lines. The aim of this study was to establish and assess the potential use of the stable HepG2 cell line expressing human augmenter of liver regeneration (hALR). The cDNA encoding hALR protein was inserted into pcDNA3.1 to generate pcDNA3.1/hALR, following which pcDNA3.1/hALR was transfected to HepG2 to establish a cell line that stably expressed hALR (HepG2 hALR). A total of 800 million HepG2 hALR cells were loaded into laboratory-scale BAL bioreactors and cultured for 4 days, during which time the parameters of hepatocyte-specific function and general metabolism were determined. The cell line that stably expressed human ALR was successfully established. The expression of recombinant hALR was higher in the HepG2 hALR cell line than in the HepG2 cell line based on immunofluorescence and immunoblot assays. In samples removed from the BAL bioreactor on day 4, compared to HepG2 cells, HepG2 hALR cells produced significantly more alpha-fetoprotein (127.3 %; P < 0.05) and urea (128.8 %; P < 0.05) and eliminated more glucose (135.7 %; P < 0.05); the level of human albumin was also higher (117 %) in HepG2 hALR cells, but the difference was not significant (P > 0.05). After 24 h of culture, the mean lidocaine removal rate was 65.1 and 57.3 % in culture supernatants of HepG2 hALR and HepG2 cell lines, respectively (P < 0.01). Based on these results, we conclude that HepG2 hALR cells showed liver-specific functionality when cultured inside the bioreactor and would therefore be a potential cell source for BAL.
