NEUROD1 and stroke disorder: For this experiment, 3 male beagle canine stroke models were used, 2 of which were given the treatment viruses “AAV9-GFAP(short)-Cre: 2.4E13 GC/mL and AAV9-CAG-DIO-NeuroD1-T2A-mRuby2: 1.0E13 GC/mL” meant to reprogram astrocytes into neurons and 1 of which was given the control viruses “AAV9-GFAP(short)-Cre: 2.4E13 GC/mL and AAV9-CAG-DIO-mRuby2: 2.5E13 GC/mL” meant to identify transduced cells.
