How to flush channels in hydrogel with endothelial cells?
To flush channels in hydrogels with endothelial cells, various innovative techniques have been developed. One method involves creating hollow, perfusable channels by encapsulating polycaprolactone fibers in cell-laden hydrogels and physically removing them, allowing for the formation of interconnected grids or hierarchically branched patterns . Another approach includes fabricating biofunctionalized polyethylene glycol hydrogel microchannels with adjustable circular cross-sections, decorated with Au-nanoparticle arrays functionalized with biomolecules, enabling control over flow conditions and biomolecule density on the channel surface . Additionally, three-dimensional bio-printing technology has been utilized to engineer vascular structures within hydrogel scaffolds, where endothelial cells are seeded in tubular form within a collagen scaffold, creating fluidic channels connected to a perfusion system for stable flow conditions . These methods showcase advancements in creating perfusable channels in hydrogels with endothelial cells for various tissue engineering applications.
