Mitochondrial clearance is preserved in unstressed Atg7^−/− transplant recipients. (A) Blood smears from Atg7^+/+ and Atg7^−/− transplant recipients, stained with Wright-Giemsa (original magnification, ×1000). Note the increased central pallor of the Atg7^−/− erythrocytes. (B) Flow cytometry of blood stained with MTR (top panels) or doubly stained with MTR and TO (bottom panels) from Atg7^+/+ and Atg7^−/− transplant recipients and Nix^−/− mice.
