Figure Lengend Snippet: Synapse formation and dendrite maturation in the Sema7A and PlxnC1 KOs. a Synapse markers within glomeruli in the Sema7A KO. OB sections of the WT and Sema7A KO at P5 and 8w were immunostained with antibodies against vGlut2 and GluR1, pre- and post-synaptic markers, respectively. Staining photos are shown for P5 sections. Signal intensities within the rI7 glomeruli were normalized by the pre-synaptic signals in the ONL and post synaptic signals in the EPL. Fluorescent signals of GL/ONL and GL/EPL in glomeruli are compared between the WT and Sema7A KO. Scale bars=25 μm. * p < 0.05, ** p < 0.01 (Student’s t -test). Error bars indicate SD ( n = 5, 6, 2, 3 animals). b Dendrite morphology of M/T cells in the Sema7A KO. EYFP-tagged rI7 glomeruli (green) were detected by immunostaining with anti-GFP antibodies. M/T cells (yellow) were visualized by Lucifer yellow (LY) injection into the rI7 glomeruli of the WT and Sema7A KO at P5 (left). The numbers of M/T cells with one dendrite (mature) and those with multiple dendrites (immature) to GL were counted for the rI7 glomeruli. The ratios (%) of mature (blue) and immature (white) M/T cells are shown (right): WT, 26/34 (76.5 %); KO, 8/34 cells (23.5 %). n = 20 glomeruli. Scale bar=10 μm. c Synapse markers within glomeruli in the PlxnC1 cKO. OB sections of the WT and PlxnC1 cKO at P5 and 8w were analyzed for synapse markers. Staining photos are shown for P5 sections. Signal intensities within the rI7 glomeruli were shown. Scale bars=25 μm. * p < 0.05, ** p < 0.01 (Student’s t -test). Error bars indicate SD ( n = 5, 5, 2, 3 animals). d Dendrite morphology in the PlxnC1 cKO. M/T cells (yellow) were visualized by LY injection into the rI7 glomeruli of the WT and PlxnC1 cKO at P5 (left). The ratios (%) of mature (blue) and immature (white) M/T cells are shown (right): WT, 24/31 (77.4 %); KO, 7/31 (22.6 %). n = 23 glomeruli. Scale bar=20 μm

Figure Lengend Snippet: Sema7A promotes dendrite maturation and synapse formation. Left, Sema7A levels in the MOR29B and MOR29A glomeruli. OB sections at P4 were immunostained with anti-Sema7A antibodies, and signal intensities of Sema7A are compared (see also Fig. ). * p < 0.05 (Student’s t -test). Error bars indicate standard deviation SD ( n = 8 glomeruli). Middle, Pre- and post-synaptic markers in the MOR29A and MOR29B glomeruli. OB sections at P4 were also immunostained with antibodies against vGlut2 and GluR1, pre- and post-synaptic markers, respectively. Relative fluorescent signals (MOR29B/MOR29A glomeruli) are compared. * p < 0.05 (Student’s t -test). Error bars indicate standard deviation SD ( n = 8 glomeruli). Right, Dendrite maturation of M/T cells in the MOR29A and MOR29B glomeruli. M/T-cell dendrites were visualized by LY injection into the MOR29A and MOR29B glomeruli at P4. The ratios (%) of mature and immature M/T cells in the MOR29A and MOR29B glomeruli are shown: MOR29A, 8/29 (27.6 %); MOR29B, 22/28 (78.6%). n = 16 glomeruli
