BMP2 cross-linked by transglutaminase 2 to collagen-plla scaffold promotes osteogenic differentiation in mesenchymal stem cells.
Article in Biotechnology letters, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Transglutaminase 2 (TG2) was used to attach biologically-active BMP2 to collagen type I-coated poly-L-lactic acid (PLLA) nanofibrous scaffolds. Irreversibly cross-linked BMP2 retained its activity and induced Smad-dependent gene expression in cells seeded on PLLA-BMP2 scaffolds. These modified scaffolds promote osteogenic differentiation of human bone marrow-derived mesenchymal stem cells (hBMSCs) cultured in low-serum and growth factor free medium and support deposition of the calcified matrix and induction of the molecular osteogenic markers Runx2, osteopontin, osteonectin and bone sialoprotein. Importantly, the PLLA-BMP2 scaffolds did not support chondrogenic differentiation in hBMSCs as there was no expression of chondrogenic markers aggrecan, Sox 9, and collagen type II, and no deposition of cartilaginous glycosaminoglycan-rich matrix. Thus, TG2-mediated cross-linking of BMP2 to a scaffold is a novel approach to induce osteoblast-specific programming of hBMSCs in a spatially controlled manner.
