Figure Lengend Snippet: Time-resolved imaging of vascular network development in vessel-on-chip by optical coherence tomography. A) Timeline of disease modeling. Vessel-on-chips were loaded and vessels were allowed to grow for 2 days. Thereafter, the vascular network was subjected to control medium, medium with high glucose and added TNF-α and IL-6, and VEGF medium for 3 more days. Vessel-on-chips were measured every day after day 2. B) Minimum intensity projections, showing the change in the vascular network in the control condition over the course of 5 days. C) Minimum intensity projections, displaying changes in vascular network for the high glucose condition on day 4 and 5. D) Minimum intensity projections, exhibiting changes in the vascular network for the VEGF condition on day 4 and 5. For a full overview of the process, see Fig. S2 in SI. Representative images shown, scale bar = 500 μm.
Article Snippet: On day 3, vascular specification was induced by adding 50 ng ml −1 vascular endothelial growth factor (VEGF) (Miltenyi Biotec, Germany) and 10 μM SB431542 (Tocris Bioscience, UK) in BPEL medium to the cells.
