Research overview

We assessed spontaneous motor function in a rat model of permanent middle cerebral artery occlusion (pMCAO) using motor function scores and magnetic resonance imaging (MRI). We assessed spontaneous motor function in a rat model of permanent middle cerebral artery occlusion (pMCAO) using motor function scores and magnetic resonance imaging (MRI).

Key findings

The analysis of alterations in the expression and functionality of brain-derived exosomal miRNAs within ischemic stroke lesions provides significant insights into the mechanisms that contribute to disease recovery.

We assessed spontaneous motor function in a rat model of permanent middle cerebral artery occlusion (pMCAO) using motor function scores and magnetic resonance imaging (MRI).

Brain-derived exosomes from the infarcted brain tissue of the animal model were extracted and high-throughput sequencing of them was performed followed by bioinformatics analysis for differentially expressed miRNAs target genes.

Real-time quantitative polymerase chain reaction (qRT-PCR) was used to measure expression levels of differentially expressed miRNAs at various time points.
