The effects of secretome of umbilical cord mesenchymal stem cells on regeneration of sciatic nerve defects in Sprague dawley rats.
Article in PloS one, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 and purposeCurrent treatments for peripheral nerve defects are suboptimal. Mesenchymal stem cell (MSC) implantation holds promise, with studies indicating their efficacy through the secretome. This study aims to assess the secretome's potency in regenerating peripheral nerve defects. ANIMALS AND
methodsTwenty-eight spraque dawley (SD) rats were divided into four groups, with a 10mm segmental sciatic nerve defect created. Group I received autografts, while Groups II, III, and IV had proximal and distal nerve stumps fixed with a conduit. Group II received MSC implantation, Group III received umbilical cord MSC secretome, and Group IV was treated with silicone conduits. Motoric recovery was assessed using the Sciatic Functional Index (SFI) at 6, 9, and 12 weeks. After 12 weeks, rats were sacrificed for measurements of gastrocnemius muscle weight ratio and sciatic nerve histomorphometry.
resultThe highest ratio of the gastrocnemius muscle were found in groups 1 and 3, namely 0.7 ± 0.06 and 0.7 ± 0.2 (p <0.001). The highest number of myelinated axons was found in group 1 and 3, namely 175.1 ± 15.9 and 168.9 ± 11.7 (p <0.001). The secretome had the similar effectiveness with autograft in promoting regeneration of the sciatic nerve defect.
interpretationThe secretome of the umbilical cord MSC can be a novel therapy in replacing autografts for the management of peripheral nerve defects.
