Fig. 3From: Septal contributions to olfactory bulb interneuron diversity in the embryonic mouse telencephalon: role of the homeobox gene Gsx2 Gsx2 germline knockout (KO) impairs the generation of septum-derived OB cells. a, b Gsx2 KO carrying the Zic3-lacZ allele showed a dramatic loss of βgal+ cells in the E18.5 OB. c, d Septum-derived (i.e. βgal+) and non-septum-derived (i.e. βgal−) Sp8+ interneurons were also severely compromised in the E18.5 Gsx2 KO OBBack to article page
