Engineering functional BMP-2 expressing teratoma-derived fibroblasts for enhancing osteogenesis.
Article in Scientific reports, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Bone morphogenetic protein 2 (BMP-2) is considered an effective growth factor for bone formation, and is used for making osteo-inductive scaffolds, but the related clinical investigations have shown low success rates. In this study, we genetically manipulated teratoma-derived fibroblast (TDF) cells by simultaneous introduction of BMP-2 and herpes simplex virus-thymidine kinase (HSV-tk) encoding genes. Self-production of BMP-2 in TDF cells strongly enhanced the alkaline phosphatase (ALP) activity, calcium content, and elevated the mRNA expression of osteogenic marker genes during in vitro osteogenesis. The bone formation volume was also remarkably enhanced in calvarial and femoral critical-size defect models. Ganciclovir (GCV) treatment induced apoptosis in TDF cells co-expressing HSV-tk and BMP-2, implying that HSV-tk suicide gene can modulate the side-effects of stem cell therapy, e.g., development of uncontrollable teratoma and tumor formation. Altogether, our findings revealed a safe and highly efficient technique with potential therapeutic applications for bone regeneration.
