In a repeat of this experiment, tumors were first detected at nine days after implantation, and the tumor volumes in Pf4-Cre and Dicer1fl/fl/Pf4-Cre mice were 66.1 ± 9.8 mm3 and 104.0 ± 10.5 mm3, respectively, at this first time point–a 1.57-fold increase in tumor volume in platelet miRNA-depleted mice. Here, PF4 is linked to neoplasm.
