Laminar integration of scaffold sheets. (A) Scaffold pairs were prepared by overlaying one scaffold sheet atop another sheet of identical rectangular shape, so that 1/3 of their lengths overlapped. The sheets were then wetted with photo-initiator and photocrosslinked. (B) Without crosslinking, some of the scaffold pairs fell apart after washing, whereas crosslinked scaffold pairs remained intact. Blue lines suggested the boundary of overlapping regions. (C) Representative load-displacement curve of crosslinked scaffold pairs showed higher resistance to separation. (D) Crosslinked scaffold pairs showed significantly higher maximum load before separation compared to non-crosslinked pairs. **, p<0.01; n=6.
