Potential sinking and accumulation of cells at the bottom of the cartridge in temperature-controlled inks like GelMA is one of their major drawbacks, as gelation proceeds slowly upon cooling (~ 20 min). This drawback is particularly noteworthy, as it results in inhomogeneous cell distribution in the printed construct. In the hybrid GelMA/bPE inks, the high viscosity and the high yield stress of the ink, both of which are attained nearly instantaneously after mixing of the polymeric components, prevented cell sedimentation in the cartridge prior to printing (analogous to the herbs in the "Italian dressing"). Therefore, the bioprinted constructs comprising hybrid GelMA/bPE hydrogels and HepG2 cells displayed a homogeneous vertical cell distribution as a result of immediate gelation in the cartridge as well as provision of adhesion sites (RGD) by the gelatin biopolymer (Figure and).
