We tested CXCL16 to recruit PMNs in a human normal synovial tissue (NL ST) severe combined immunodeficient (SCID) mouse chimera injected intragraft with gouty SF.

Fucosyltransferases synthesize fucosylated glycans and may play a major role in vascular biology. To examine the role of an alpha(1,2) fucosyltransferase (Fut2) in angiogenesis. We found that Fut2 mRNA and protein expression is inducible in human dermal microvascular endothelial cells (HMVECs). After finding that Fut2 is inducible in HMVECs, we examined if Fut2 contributes to angiogenesis. We found that Fut2 null endothelial cell (EC) migration and tube formation were significantly less compared to wild type (wt) ECs. Angiogenesis was impaired in Fut2 null compared to wt mice in the mouse Matrigel plug and the sponge granuloma angiogenesis assays. To assess the characteristics of Fut2 null ECs in vivo, we performed Matrigel plug angiogenesis assays in wt mice using Fut2 null and wt mouse ECs. We found a significant decrease in Fut2 null EC incorporation in neoangiogenesis compared to wt ECs. ERK1/2 activation, fibroblast growth factor receptor2, and vascular endothelial growth factor expression were less in Fut2 null ECs, suggesting a possible mechanism of impaired angiogenesis when Fut2 is lacking. These data suggest a novel role for Fut2 as a regulator of angiogenesis.
