(A) Experimental design for NP-Ficoll immunization: 28 days post-SCI or post-laminectomy, mice were immunized with NP-Ficoll and the splenic tissue was analyzed at day 4.5. (B) Representative FACS gating strategy to identify NP-specific B cells. Dot plots show the frequency of Aqua−CD4−CD8−F4/80−Gr1−Igκ−Igλ+NP+ responding B cells among live singlets. (C) Total number of NP-specific B cells. (D) Total number of NP-specific IgM ASCs. For all data sets, n=5 for un-injured, n=7 for T9-Lam, n=6 for T9-SCI, n=7 for T3-Lam, and n=8 for T3-SCI. ** denotes significance at p<0.01.
