Figure 1. The pMCAO model produced cortical infarcts where core, periinfarct, and contralateral areas were isolated for RNA extraction.

Sprague-Dawley rats were subjected to permanent middle cerebral artery occlusion with a 9-0 suture for 24 h or 3 d (a) Schematic drawing of brain areas used for tissue sampling and RNA extraction.
