Figure 11. LSCM images of β1 integrin immuno-fluorescence at posterior suture branches. A-B: Paired fluorescent (A) and DIC (B) images of a posterior suture branch (arrows). The marked reduction in β1 integrin immuno-fluorescence was apparent in fiber ends at, and approaching the sutural region of fiber end migration. A and B are at identical maginificaiton. C-D: Higher magnification of paired fluorescent (C) and DIC (D) micrographs at a posterior suture branch. C: Approaching the suture, β-1 integrin was dispersed throughout the BMC (circled fiber end profiles). D: Within the nascent sutures (double-headed arrow), the paucity of label for β-1 integrin was apparent. C and D are at identical magnification.
