Effects of hypoxias and scaffold architecture on rabbit mesenchymal stem cell differentiation towards a nucleus pulposus-like phenotype.
Article in Biomaterials, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 33 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
Nucleus pulposus grafts are needed for patients requiring replacement of their degenerated intervertebral discs. Bone marrow-derived mesenchymal stem cells (MSCs) are a potential autologous stem cell source for the nucleus pulposus regeneration. One of the key issues of constructing functional nucleus pulposus using MSCs, however, is to differentiate MSCs into nucleus pulposus phenotype in vitro and to maintain their phenotypic stability in vivo. In this study, three-dimensional (3D) nanofibrous poly(l-lactide) (PLLA) scaffolds were seeded with multi-potent rabbit MSCs and the constructs were induced along nucleus pulposus development routes in a hypoxia chamber (2% O(2)) in the presence of TGF-β1. It was found that nanofibrous scaffold could support the differentiation of rabbit MSCs towards a nucleus pulposus-like phenotype in vitro, as evidenced by upregulated expression of a few important nucleus pulposus-associated genes (aggrecan, type II collagen and Sox-9), abundant deposition of extracellular matrix (glycosaminoglycan (GAG) and type II collagen), and the continuous expression of the nucleus pulposus-specific marker, hypoxia-inducible factor (HIF)-1α. The subcutaneous implantation results confirmed that hypoxic induction before implantation could help the constructs to retain their phenotype and resist calcification in vivo. Therefore, the above data showed the promise of using 3D nanofibrous scaffolds in combination with TGF-β1 and hypoxic induction to regenerate functional nucleus pulposus grafts for intervertebral disc replacement.
