Results
Specimen 6a beta-3GnT1+/-: postnatal day 10; B3gnt2Gt(KST308)Byg/B3gnt2+, Or8a1btm2Mom/Or8a1b+ (more )
Structure Level Pattern Image Note
TS28: olfactory epithelium Present 6a beta-3GnT1+/-
Specimen 6a beta-3GnT1-/-: postnatal day 10; B3gnt2Gt(KST308)Byg/B3gnt2Gt(KST308)Byg, Or8a1btm2Mom/Or8a1b+ (more )
Structure Level Pattern Image Note
TS28: olfactory epithelium Present 6a beta-3GnT1-/- There was a reduction of labeled neurons in the mutant.
Specimen 6b beta-3GnT1+/-: postnatal day 10; B3gnt2Gt(KST308)Byg/B3gnt2+, Or8a1btm2Mom/Or8a1b+ (more )
Structure Level Pattern Image Note
TS28: main olfactory bulb olfactory nerve layer Present 6b beta-3GnT1+/-
TS28: main olfactory bulb glomerular layer Present Regionally restricted 6b beta-3GnT1+/- Labeled axons converge on a glomerulus on the dorsomedial surface of the extreme caudal olfactory bulb.
Specimen 6b beta-3GnT1-/-: postnatal day 10; B3gnt2Gt(KST308)Byg/B3gnt2Gt(KST308)Byg, Or8a1btm2Mom/Or8a1b+ (more )
Structure Level Pattern Image Note
TS28: main olfactory bulb olfactory nerve layer Present 6b beta-3GnT1-/- Labeled axons in the mutant primarily remain in the nerve layer and fail to converge on the typical glomerular position.
TS28: main olfactory bulb glomerular layer Absent 6b beta-3GnT1-/-
