Three-dimensional Collagen Scaffolds in Cultures of Olfactory Ensheathing Cells Used for Severed Spinal Cord Regeneration.

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
BACKGROUND/
aimThe regeneration of a completely damaged spinal cord is still a challenge in modern medicine. A promising treatment method is autologous transplantation of olfactory ensheathing cells (OECs). This study aimed primarily to test methods of culturing OECs with the use of materials and reagents that are certified for pharmaceutical use in the production of an advanced cell therapy product intended for humans. MATERIALS AND
methodsThe culture of OECs was performed using various modifications of the surface of the culture vessels (with fibronectin and poly-D-lysine). The number of cells was assessed after immunofluorescence staining using anti-fibronectin and anti-p75 NGF receptor antibodies. The study compared, in terms of surgical manipulations, scaffolds with OECs prepared based on 3 types of collagen: Acid Solubilized Telo Collagen and Pepsin Solubilized Atelocollagen, and the popular Corning collagen.
resultsWe have shown that when suspending OECs in collagen gel, it is much better to use acid-solubilized collagen (ASC) than pepsin-solubilized collagen (PSC) because the 3D collagen scaffold from ASC provides much easier handling of the product during a surgical procedure. We also found that the OEC cultures should be grown on the surface modified with fibronectin. Furthermore, we have also shown that the optimal concentration of fetal bovine serum (FBS) for culturing these cells should be around 10%.
conclusionThe culture of OECs based on reagents intended for human use can be successfully carried out, obtaining sufficient OECs content in the heterogeneous cell culture to produce a functional advanced therapy medicinal product.
