Correction to: A Tumor-on-a-Chip System with Bioprinted Blood and Lymphatic Vessel Pair (Advanced Functional Materials, (2019), 29, 31, (1807173), 10.1002/adfm.201807173)

DOI: 10.1002/adfm.201807173 In the original version of this article in Figure 6B, the right panels were accidentally placed in redundancy with the left panels. Upon further understanding of the issue, it was identified that for this specific set of data, the microscopy images were not saved correctly leading to the same set of images being collected for Figure 6B right panel at time points 60 min, 12 h, and 24 h. This error is now corrected in the updated Figure 6, where the entire right panels of images (including time point 5 min) have been replaced with an independent set of data collected for the same experimental group. 6 Figure (Figure presented.) Biomolecule and drug transport in the TOC-BBL. A) FITC, FITC–BSA, and FITC-dextran were examined for their diffusion profiles in the TOC-BBL under the two-channel configuration. B) The diffusions of DOX were examined in one-/two-channel configurations in the TOC-BBL. C) The comparisons of diffusion constants of various biomolecules and DOX measured in the TOC-BBL. * P < 0.01. These errors do not affect the conclusions of the report.
