NEUROD1 and stroke disorder: In the stroke-injured mice, there were significantly more XFP+ neurons in Neurod1 (2.78 ± 0.7% and 20.2 ± 3.1%, at day 21 and day 56, respectively) compared to Cre-injected brains (0.47 ± 0.26% and 4.67 ± 0.91%, at day 21 and day 56, respectively) (p = 0.031 for day 28 and p < 0.0001 for day 56) (Figure 2a).
