PAX6 and ischemia: PAX6 is a pro‐neurogenic transcription factor and highly expresses in reactive astrocytes following ischemia (Duan et al., 2015; Steliga et al., 2013), and it plays a key role in the conversion of astrocytes into neurons (Buffo et al., 2005; Heins et al., 2002; Kronenberg et al., 2010).
