was conducted (EnVison+ System-HRP (DAB), DakoCytomation, Glostrup, Denmark) with
diaminobenzidine substrate, then counterstaining with hematoxylin. Positive stained cells were
counted from five randomly selected non-overlapping 200X fields.
Statistical analysis
Results of statistical analyses are expressed as means ± SEM. Differences among experimental
groups were confirmed by one-way ANOVA followed by Dunnett's test for individual
comparison of group means vs the control group. Survival analyses were compared by a log-
rank test. These calculations were performed with SigmaStat v3.10 (Systat Software Inc,
Richmond, CA). The null hypothesis was rejected when P < 0.05.NIH-PA Author Manuscript
