The original version of this article unfortunately contained a mistake. An error in Fig. 1C. The panel 769P CM-vector control and CM-let-7d were overlapped.

The corrected Fig. 1 is given in the following page.

Fig. 1.

The conditioned medium from let-7d-overexpressing RCC cells had no effects on the proliferation, migration and tube formation of HUVECs. a, b The cell proliferation assay showed that conditioned medium from let-7d transfected 786O and 769P cells had no significant influence on proliferation of HUVEC cells compared with that from vehicle control transfected cells. The data represent the mean ± SD of three independent experiments with triplicates of each group. c, d Boyden chamber assays were performed, showing that HUVEC cell migration was not significantly different in conditioned medium from let-7d-overexpressing 786O and 769P cells compared with that in conditioned medium from respective control cells. Original magnification: × 20. e, f Tube formation assay showed that the number of tubes formed by HUVEC cells in conditioned medium from let-7d-overex-pressing 786O and 769P cells was not significantly different from those in conditioned medium from respective control cells. Bar, 500 μm. The quantification results of migrated cells and number of tubes per well were plotted in the right. Results were displayed as the mean ± SD of three independent experiments with five random fields counted for each chamber/well. Different numbers between two groups were analyzed by two-tailed Student’s t test. *p < 0.05
