Alginate-gelatin bioink for bioprinting of hela spheroids in alginate-gelatin hexagon shaped scaffolds

Generating a tissue model mimicking the cervix could be useful for studying treatment of precancerous lesions. In this work, bioprinting of hexagon shaped alginate-gelatin scaffolds laden with HeLa spheroids was presented. The three-dimensional (3D) printing system was designed to extrude alginate-gelatin bioink of different  viscosities at an extrusion rate of 1–5 mL/min and printing speed from 10 to 50 mm/s. The biophysical properties of the...
