While evidence suggests this can enhance stroke recovery, the underlying molecular mechanisms initiating the response are poorly understood. Here we identified changes in protein expression in the ipsilateral VZ early (4\u00a0h) after stroke to gain insight into the initial mechanisms involved in NPC activation post\u2010stroke.<\/jats:p><\/jats:sec><jats:sec><jats:title>Experimental design<\/jats:title><jats:p>Four hours after photothrombotic stroke (or sham surgery control) in the sensorimotor cortex, adult mice (10 stroke, 10 sham) were subjected to cardiac perfusion with PBS, and ipsilateral and contralateral VZ tissue was microdissected. Two separate sets of ipsilateral and contralateral VZ tissues (from 5 pooled surgery or 5 pooled sham mice) were analyzed simultaneously using 8\u2010plex iTRAQ.
