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

backgroundCulture protocols need to yield 100 million equine synovial fluid (SF)-derived mesenchymal stromal cells (SF-MSCs) in around 3 weeks are needed, before these cells can be evaluated as agents of articular repair in clinical trials.

objectivesTo investigate mass culture of equine SF-MSC culture protocols using nonwoven polyethylene terephthalate (PET) fabrics for the potential to meet the targets for clinical trials. STUDY

designIn vitro experiments.

methodsSF samples were collected from the carpal joints in thoroughbred racehorses (n = 21) undergoing arthroscopic surgery and cultured in 10% fetal bovine serum (FBS-protocol; n = 7) or 10% equine serum (ES-protocol; n = 7)-supplemented medium. Primary (P0) SF-MSCs were isolated by dish culture and then passaged on nonwoven PET fabrics in culture bottles at a seeding density of 1 × 10

resultsUnder the FBS and ES protocols, 0.84 ± 0.82 × 10 MAIN LIMITATIONS: Visualisation of SF-MSC attached to PET nonwoven fabric, counting of SF-MSCs attached to and detached from PET nonwoven fabric, and daily quantification of SF-MSC proliferating on fabrics.

conclusionsTo support progress to clinical trials, of a sufficient number (100 million) of equine SF-MSCs need to be harvested in around 3 weeks. These goals were achieved with the FBS protocol, but further optimisation is needed for the ES protocol. Our findings on in vitro MSCs amplification suggest that SF, a potential source for non-invasively collected MSCs, is available as a promising matrix for therapeutic strategies using autologous transplantation.
