MKI67 and neoplasm: Tumor tissue formed by HOXA5-overexpressing cells showed much more HOXA5 staining (Fig. 3i, j, 2.83 ± 0.75 vs. 9.23 ± 1.55, p < 0.001; 1.53 ± 0.67 vs. 8.51 ± 1.43, p < 0.001) but weaker Ki67 staining (Fig. 3i, j, 10.50 ± 0.67 vs. 2.13 ± 1.10, p < 0.001; 11.00 ± 0.63 vs. 0.83 ± 0.48, p < 0.001) than those formed by the control cells.
