μGels enable enhanced cell infiltration in dense fibrin ECMs compared with fibrin-only controls. Average migration speeds are shown for cells polymerized in fibrin alone, or various fibrin–μgel hybrid constructs. Box and whiskers plot shown, migration distance averaged from 5 measurements from n = 12 gels from 2 independent biological replicates (represented as median with 75th to 25th percentile with minimum and maximum). A two-way ANOVA with Bonferroni’s multiple comparisons test was performed and statistically significant differences were found between ±μgels (P < 0.0001) at each time point.
