Additional file 1: Figure S 1. A) Representative sections of DDK staining following AAV-Gas6 injection into the hippocampus of C57Bl/6J mice demonstrates spread of virus throughout the hippocampus. Scale bar = 100 μm. B, C) Western blot for pAxl and Axl on hippocampal lysates from mice treated with either 1E10 vg/mL or 1E12 vg/mL AAV-Gas6 or AAV-control. N=3-4 per group, error bars represent mean +/- SEM. Unpaired two-tailed t-test, *p=0.0107, ***p=0.0007.
