Stem cell attraction via SDF-1α expressing fat tissue grafts.
Article in Journal of biomedical materials research. Part A, 2013. 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
Mesenchymal stromal cell (MSCs) are key cellular components for site-specific tissue regeneration. The chemokine stromal derived factor 1 alpha (SDF-1α) is known to attract stem cells via the C-X-C chemokine receptor-4 (CXCR4) receptor. The aim of the study was to develop a model for stem cell attraction using SDF-1α overexpressing fat tissue grafts. Murine MSCs were lentiviral transduced to express the genes for enhanced green fluorescent protein, firefly luciferace, and human CXCR4 (hCXCR4). Murine fat tissue was adenoviral transduced to express SDF-1α and red fluorescent protein transgenes. MSCs were cultured on transwells with SDF-1α containing supernatants from transduced fat tissue. The numbers of migrated MSCs in four groups (with hCXCR4 positive (+) or hCXCR4 negative (-) MSCs with or without SDF-1α containing supernatant) were investigated. After 36 h of culture, 9025 ± 925 cells migrated through the membrane of the transwells in group 1 (CXCR4+/SDF-1α+), 4817 ± 940 cells in group 2 (CXCR4-/SDF-1α+), 2050 ± 766 cells in group 3 (CXCR4+/SDF-1α-), and 2108 ± 426 cells in group 4 (CXCR4-/SDF-1α-). Both, the presence of SDF-1α and the expression of hCXCR4 significantly increased the migration rates (p < 0.0001). MSCs overexpressing the CXCR4 receptor by lentiviral transduction are highly attracted by medium from SDF-1α expressing fat tissue in vitro. Thus, SDF-1α activated tissue grafts may be a strategy to enhance site-specific musculoskeletal tissue regeneration.
