1 · What the graph read from it

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.

2 · The registry

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 stem cells (MSCs) are an attractive cell type for cartilage repair that can undergo chondrogenesis in a variety of three-dimensional (3D) scaffolds. Hyaluronic acid (HA) hydrogels provide a biologically relevant interface for cell encapsulation. While previous studies have shown that MSC-laden HA constructs can mature in vitro to match native mechanical properties using cells from animal sources, clinical application will depend on the successful translation of these findings to human cells. Though numerous studies have investigated chondrogenesis of human MSC (hMSC)-laden constructs, their functional outcomes were quite inferior to those using animal sources, and donor-specific responses to 3D HA hydrogels have not been fully investigated. To that end, hMSCs were derived from seven donors, and their ability to undergo chondrogenesis in pellet culture and HA hydrogels was evaluated. Given the initial observation of overt cell aggregation and/or gel contraction for some donors, the impact of variation in cell and HA macromer concentration on functional outcomes during chondrogenesis was evaluated using one young/healthy donor. The findings show marked differences in functional chondrogenesis of hMSCs in 3D HA hydrogels based on donor. Increasing cell density resulted in increased mechanical properties, but also promoted construct contraction. Increasing the macromer density generally stabilized construct dimensions and increased extracellular matrix production, but limited the distribution of formed matrix at the center of the construct and reduced mechanical properties. Collectively, these findings suggest that the use of hMSCs may require tuning of cell density and gel mechanics on a donor-by-donor basis to provide for the most robust tissue formation for clinical application.
