Direct comparison of the thin layer angiogenesis (TLA) assay with standard thick layer assay. Comparison of the average number of branches/field (manual count) formed by HUVEC (25,000 cells/cm2) in the presence or absence of VEGF (25 ng/ml) in the standard thick layer assay (A) and the TLA assay (B). **p < 0.01 vs. control as determined by student's paired t-test.
