Macrophage chemoattraction by locally injected recombinant chemokines in cxcr3.2 mutant and wild-type siblings. Recombinant proteins or buffer (mock) were injected into the hindbrain ventricle at 30 hpf and macrophages accumulating in 3 hours within the hindbrain limits were counted as Lp-stained cells. Data were accumulated from three independent experiments. (A) Cxcl11aa (1.2 mg/ml). Sample size (n): 51, 60, 55, 60. (B) Cxcl11ae (0.5 mg/ml). Sample size (n): 54, 51, 42, 56. (C) Cxcl11af (0.5 mg/ml). Sample size (n): 47, 68, 39, 58. Error bars: median and interquartile range. Note that macrophage chemoattraction mediated by Cxcl11aa and Cxcl11af is abolished by cxcr3.2 mutation, whereas the chemoattraction mediated by Cxcl11ae is independent of cxcr3.2. ns, non-significant; **P<0.01; ***P<0.001.
