Hepatocyte production across embryonic stages in chicken: an in vitro approach.
Article in BMC veterinary research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundChicken hepatocytes are a valuable resource for cell-based assays and investigating the underlying mechanisms of diseases.
objectiveIn this study, we examined in vitro generation of chicken hepatocytes from three embryonic developmental stages.
methodsHepatocytes were isolated from 5-, 7-, and 10-day-old chicken embryos and cultured in DMEM/F12 + 10% FBS. After 3 days, we measured proliferation rate, the expression of hepatocyte-specific genes (AFP, ALP, FOXA2, CYP3A4, CXCR4, OCT4, NANOG, SOX17), enzyme activity (ALT, AST), albumin production, and urea secretion.
findingsMorphological examination of individual hepatocytes exhibited a characteristic hexagonal structure with prominent nuclei and nucleoli. E10 embryos exhibiting a markedly higher proliferation rate in comparison to those from E5 and E7 stages (until 20 days). Whereas, approximately 50% of E5 and E7 hepatocytes showed reduced proliferation after three days. In suspension culture, hepatocytes formed spheroids or hepatospheres. The expression of hepatocyte-specific genes (AFP, ALP, FOXA2, and CYP3A4) was higher in E10 compared to E5 hepatocytes. The expression of stemness/early developmental markers (CXCR4, OCT4, NANOG, and SOX17) was significantly lower in E10 than E5 hepatocytes. E10 hepatocytes revealed significantly increased ALT and AST expression and urea secretion. While, Albumin production was significantly lower in E10 hepatocytes.
conclusionOur results invested that E10 is the optimal developmental stage for the derivation and proliferation of chicken hepatocytes in vitro.
