Trunk granuloma formation and induction of angiogenesis by M. marinum.
(A,B) Schematic representation of injection location and of granuloma expansion in zebrafish embryos/larvae upon injection of Mm into the trunk. (C–E) Longitudinal imaging of vascular and bacterial growth during development of a trunk granuloma in the Tg(kdrl:eGFP) line at 3, 4 and 5 dpi. (F–K) Formation of trunk granulomas and their vascularisation in a cxcr4b+/+ and cxcr4b−/− larva at 5 dpi. White arrows indicate sites of abnormal vascularisation associated to bacterial growth, notably largely initiated in the wt but rare in the mutant. See also Fig. 2 for quantification. Scale bars: 100 μm.
