(A) Live 3D images of wild-type and slbp1 mutant retinas with Tg[mfap4:tdTomato-CAAX; ath5:EGFP] at 49 hpf. Only mfap4:tdTomato-CAAX-positive ocular microglial precursors and peripheral macrophages are shown as surface-rendered objects. Original images are shown in Figure 4—figure supplement 2A. Scale bar: 30 μm. (B) Histogram of numbers of ocular microglial precursors in slbp1 mutants and wild-type siblings. mfap4-positive microglial precursors are significantly fewer in slbp1 mutants. Bars and lines indicate means ± SD. ***p < 0.001. (C) Live 3D images of wild-type and slbp1 mutant trunk with Tg[mfap4:tdTomato-CAAX; ath5:EGFP] at 49 hpf. Scale bar: 70 μm. (D) Histogram of numbers of trunk macrophages in slbp1 mutants and wild-type siblings. There is no significant difference in mfap4-positive macrophage number in trunks of slbp1 mutants. Bars and lines indicate means ± SD. (E) Live 3D images of retinas of Tg[rx1:gal4-VP16; mfap4:tdTomato-CAAX] embryos injected with one DNA construct encoding UAS:EGFP (left) or two DNA constructs encoding UAS:EGFP; UAS:myc-tagged NICD (right) at 44 hpf. Only mfap4:tdTomato-CAAX-positive ocular microglial precursors and peripheral macrophages are shown as surface-rendered objects. Original images are shown in Figure 4—figure supplement 2B. Scale bar: 30 μm. (F) Histogram of numbers of ocular microglial precursors in rx1:gal4-VP16; UAS:EGFP expressed and rx1:gal4-VP16; UAS:EGFP; UAS:myc-NICD expressed wild-type retinas. mfap4-positive microglia are significantly decreased in myc-NICD expressed retinas, compared with non-injection control and EGFP expressed control retinas. Bars and lines indicate means ± SD. *P < 0.05, ***P < 0.001. (G) Live 3D images of standard MO- and ath5 MO-injected retinas of Tg[mfap4:tdTomato-CAAX; ath5:EGFP] embryos at 49 hpf. Only mfap4:tdTomato-CAAX-positive ocular microglial precursors and peripheral macrophages are shown as surface-rendered objects. Original images are shown in Figure 4—figure supplement 2C. Scale bar: 30 μm. (H) Histogram of numbers of ocular microglial precursors in standard MO and ath5 MO-injected wild-type retinas. mfap4-positive microglial precursors are significantly less numerous in ath5 morphant retinas. Bars and lines indicate means ± SD. *p < 0.05.
