Figure 3. Increased survival of neurons in MOR KO mice is not due to a detectable decrease in levels of apoptosis.

Quantitative analysis of (A) activated caspase-3-IR cells, (B) TUNEL-positive cells, and (C) pyknotic cells in the GCL. Representative images of (D) activated caspase-3 cells (indicated by white arrowhead), (E) TUNEL-positive cells (indicated by gray arrowheads), and (F) pyknotic cells (indicated by black arrows) in the GCL. Data for A–C are presented as mean ± SEM. Scale bar, 50 µm. Inset scale bar, 10 µm.
