The following experiments were performed in glial shNf-1/shTp53 glial cells serum starved 4 hr before assaying. Cells were expressing either Cas9 alone (control) or Cas9 and sgRNA targeting Atg7 (sgAtg7 #1 or #2). F: Cells stably expressing mCherry-Rab5 were stimulated with 20 ng/mL EGF for indicated times before immunofluorescence staining against EGFR. Scale bar: 10 μm.
