A, B In modified Boyden chamber experiments, confluent dermal HMVECs were stimulated with tumor cell-conditioned media (TC-CM)-that is, media conditioned by either LM2-4luc, SN12luc, or HT29luc tumor cells-and treated with 20 ng/mL Vasculotide vs. 400 ng/mL Ang1 (positive control) vs. PBS (negative control). Meta-analyses of treatment effects on dextran permeability (A) and tumor cell migration (B), where each datapoint represents the mean of an independent experiment, averaged over 2-3 biological replicates (inserts) per treatment group and normalized internally within that same experiment. Statistical significance of overall Ang1 or VT treatment effects was determined by paired t-tests, n = 11 (A) or 6 (B) experimental replicates.C Representative fluorescent images (10×) of 'extravasated' CMTPX-labeled TCs (red) fixed on membrane undersides.
