Characterization and establishment of an immortalized rabbit ovary granulosa cell line for reproductive biology experiments.
Article in In vitro cellular & developmental biology. Animal, 2024. 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
Granulosa cells (GCs) are the key components of ovarian follicles and regulate the maturation, communication, growth, and development of oocytes. GCs have great potential as human therapeutic models and in livestock breeding. In this study, we established an immortalized cell line (Im-RGCs) by transforming primary rabbit granulosa cells (Pri-RGCs) with lentivirus-mediated simian virus 40 Large T (SV40LT). Morphologically, Im-RGCs were indistinguishable from Pri-RGCs and maintained intact cell structure as observed by H&E staining. Also, Im-RGCs exhibited no significant change in cell proliferation, viability, and growth. Furthermore, GC-specific markers, such as FSHR, StAR, CYP11A1, and CYP19A1, were examined by PCR, immunofluorescence, and Western blotting. ELISA and karyotype analysis showed that Im-RGCs can synthesize steroid hormones and maintain the normal number of chromosomes during the infinite passage. Furthermore, soft-agar cloning and nude mice tumorigenic experiments indicated the absence of any malignancy transformation in Im-RGCs. In conclusion, we successfully established the immortalized granulosa cell line of rabbit follicles that can be used for biological, animal husbandry, and female reproductive research.
