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

introductionExosomes are nanoscale extracellular vesicles that widely participate in intercellular communication. An increasing number of studies have reported on the neuroprotective effects of stem cell-derived exosomes in brain diseases through various delivery methods. However, only a few reports are available on the delivery and uptake of stem cell-derived exosomes in the brains of mice of different ages.

methodsPKH-26-labelled mesenchymal stem cell-derived exosomes were collected, and their uptake was investigated in the brains of mice aged 2 weeks, 2 months, and >6 months, 24 hours after intranasal delivery.

resultsNo exosomes were distributed in the whole brains of 2-week-old mice after 24 hours of intranasal delivery. However, a small number of exosomes were found in the olfactory bulb, cortex, and hippocampus of 2-month-old mice, with no exosomes observed in the cerebellum. In contrast, a large number of exosomes were ingested in all brain regions, including the olfactory bulb, cortex, hippocampus, and cerebellum, of >6-month-old mice.

conclusionExosomes can enter the brains of adult mice through intranasal administration, but there are differences in the uptake rate among mice of different ages. These findings provide a theoretical basis for the future clinical administration of exosomes for treating brain disorders.
