Figure 6From: TNFA deletion alters apoptosis as well as caspase 3 and 4 expression during otitis mediaApoptosis in the ME mucosa during OM. A. Micrographs illustrating TUNEL-labeled cells in the ME mucosae of WT versus TNFA-/- mice after inoculation of the ME with NTHi. B. Percentage of apoptotic cells in the ME mucosa following NTHi injection. Values are means ± SD; asterisks indicate statistical significance (p ≤ 0.05); n = 6-10 for each group.Back to article page
