[Corrigendum] HIF-1α contributes to tube malformation of human lymphatic endothelial cells by upregulating VEGFR-3.

Subsequently to the publication of the above article, the authors have realized that Fig. 4 on p. 145 (showing the results from the colony formation assay) was published containing erroneous images in Fig. 4C. Essentially, incorrect images were selected to represent the negative control (NC) experiments owing to an altered shooting angle and incorrect naming of the files. The corrected version of Fig. 4, now showing the correct data for the NC experiments in Fig. 4C, is shown on the next page. The authors confirm that the error made in the presentation of Fig. 4 did not adversely affect either the results or the conclusions reported in this paper, and they are grateful to the Editor of for granting them this opportunity to publish a Corrigendum. They also apologise to the readership for any inconvenience caused. [International Journal of Oncology 54: 139-151, 2019; DOI: 10.3892/ijo.2018.4623].
