Intravenous administration exosomes derived from human amniotic mesenchymal stem cells improves neurological recovery after acute traumatic spinal cord injury in rats.

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
Objectives: Our previous study has showed that human amniotic mesenchymal stem cells (hAMSCs) transplantation improves neurological recovery after traumatic spinal cord injury (TSCI) in rats. However, less is known about the effects of exosomes derived from hAMSCs for TSCI. Here, we investigated whether hAMSCs-derived exosomes improve neurological recovery in TSCI rats and the underlying mechanisms. Materials and Methods: A rat traumatic spinal cord injury (TSCI) mode was established using a weight drop device. At 2 hr after TSCI, rats were administered either hAMSCs-derived exosomes or phosphate buffered saline via the tail vein. Locomotor recovery was evaluated by an open-field locomotor rating scale and gridwalk task. Spinal cord water content, hematoxylin and eosin (H&E) staining, Evans blue (EB) dye extravasation, immunofluorescence staining, and enzyme-linked immunosorbent were performed to elucidate the underlying mechanism. Results: hAMSCs-derived exosomes significantly reduced the numbers of ED1 Conclusion: Taken together, these findings demonstrate that hAMSCs-derived exosomes have favourable effects on rats after acute TSCI, and that they may serve as an alternative cell-free therapeutic approach for treating acute TSCI.
