Quantitative analysis of the Matrigel-based invasion assay of normal MCF 10A and neoplastic MDA-MB-231 cells infected with B. burgdorferi compared to uninfected cells after 72 h using 2 mg/mL concentration of Matrigel as described in Material and Methods. The p-value of the data < 0.05 is considered significant and is indicated by *. The error bar represents a standard error of mean (SEM). All experiments were performed a minimum of three independent times with at least six samples per experiment (n = 18).
