Engraftment and Repopulation Potential of Late Gestation Fetal Rat Hepatocytes.
Article in Transplantation, 2017. 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
backgroundThe limited availability of donor organs has led to a search for alternatives to liver transplantation to restore liver function and bridge patients to transplantation. We have shown that the proliferation of late gestation (embryonic day 19) fetal rat hepatocytes is mitogen-independent and that mechanisms regulating mRNA translation, cell cycle progression, and gene expression differ from those of adult rat hepatocytes. In the present study, we investigated whether E19 fetal hepatocytes can engraft and repopulate an injured adult liver.
methodsFetal hepatocytes were isolated using a monoclonal antibody against a hepatic surface protein, leucine amino peptidase (LAP). LAP+ and LAP- fractions were analyzed by immunofluorescence and microarray. Immunopurified E19 liver cells from DPPIV+ rats were transplanted via splenic injection into partial hepatectomized DPPIV- rats that had been pretreated with mitomycin C.
resultsMore than a third of LAP+ fetal hepatocytes expressed ductal markers. Transcriptomic analysis revealed that these dual-expressing cells represent a population of less well-differentiated hepatocytes. Upon transplantation, LAP+ late gestation fetal hepatocytes formed hepatic, endothelial, and ductal colonies within 1 month. By 10 months, colonies derived from LAP+ cells increased so that up to 35% of the liver was repopulated by donor-derived cells.
conclusionsLate gestation fetal hepatocytes, despite being far along in the differentiation process, possess the capacity for extensive liver repopulation. This is likely related to the unexpected presence of a significant proportion of hepatocyte marker-positive cells maintaining a less well-differentiated phenotype.
