The authors have advised that Figure 4 on page 9611 is incorrect. The images for Figure 4G and L (GelMA) and Figure 4I (GrG2) were mistakenly taken from the wrong image folders.
The correct Figure 4 is shown below. The authors apologize for these errors and advise they do not affect the results or conclusion of the paper.
Figure 4.
(A–E) Cell viability (Live/Dead assay) on Endothelial cells, (F–J) 3T3 fibroblast cells and (K–O) HaCat keratinocyte cells for control, blank GelMA hydrogel, 0.001 wt% rGO loaded GelMA hydrogel (GrG1), 0.002 wt% rGO loaded GelMA hydrogel (GrG2) and 0.004 wt% rGO loaded GelMA hydrogel (GrG4) respectively. Green channel depicts live cells, while red channels depict dead cells. (P) Quantitative comparison of the percentage of dead cells. The scale bar at the right lower corner is 1000 μm.
