Percentage reductiona of endothelial tube length in HUVE cells.

aReductions are calculated based on comparisons between the tube lengths of antibody treatments and no antibody treatments. Average tube length of the “No antibody” treatment was set to 100%.bThe negative value is indicative that the average tube length was 21.62% greater than that on the “ No antibody” treatment (therefore 121.62%) and therefore rather than a tube reduction an increase was observed.
