Secretagogin^−/− mice demonstrate successful loss of function. (A and A₁) Secretagogin⁺ neurons in wild-type RMSs typically expressed calretinin (black arrowheads). The white arrowhead points to a secretagogin⁺/calretinin⁻ neuron). (B–C₁) Secretagogin^−/− mice lacked secretagogin expression in both the olfactory bulb (B and B₁) and RMS (C and C₁). (Scale bars: 100 µm in C and C₁; 20 µm in B and B₁; 10 µm in A and A₁.)
