FIG. 1.

Schematic illustration of the generation of cell arrays by LaBP. Step 1: The first HA–fibrinogen layer is blade-coated on the collector slide and subsequently wetted with the crosslinking agent; Step 2: The first (green spots) and second (red spots) cell types are printed in separated spot arrays at a defined distance to each other by means of LaBP; Step 3: The second HA–fibrinogen layer is blade-coated on top of the cell array and subsequently wetted by a crosslinking agent. LaBP, laser-assisted bioprinting. Color images available online at www.liebertonline.com/tec
