We investigated the therapeutic effect of the extracellular vesicles secreted by glial progenitor cells (GPC-EV) derived from human induced pluripotent stem cell in a traumatic brain injury model. The injury was modeled using the dosed concussion to the open brain method. The male Wistar rats were performed traumatic brain injury (TBI), and after 24 hours animals were randomly divided into two groups: group 1 — rats with intranasal administration of PBS (control), and group 2 — rats with similar administration of extracellular visicles (EV) derived from glial progenitor cells. PCR analysis of brain tissues ( cortex, striatum, hippocampus) were performed on postoperative day 7 and 14 to investigate genes associated with apoptosis, and inflammation.
Overall design
qPCR gene expression profiling. The brain tissue was collected at 7 and 14 days post-TBI, as indicated in the summary.
