Ink-H4-RGD showing good extrudability and biocompatibility in MDA-MB-231 WT cells. (A) Live/dead cell assay analysis using Calcein AM/Ethidium homodimer III staining. Results shown were representative of three independent experiments. Microscopic images were acquired and analysed by using Olympus Microscope IX71 and cellSens Standard software (version 1.16; Tokyo, Japan) respectively. (B) Post-printing cell viability of MDA-MB-231 WT cells, which is expressed as percent viability as analysed by NIH ImageJ software (1.43u; https://imagej.nih.gov/ij). (C) Extrusion pressure required for printing of bioinks.
