LGALS4 and acute lymphoblastic leukemia: We imaged the developing ALL using transgenic lines Tg (HGn39D:GFP)bc2Tg, also referred to as sill:GFP (sensory innervation of the lateral line), which labels the primary sensory afferent neurons of the lateral line; Tg (Brnc3:GFP)s356t, which labels hair cells (Figures 2A, C); and Tg (isl2b:Gal4)zc65, which labels many cranial sensory neurons (Figure 2B).
