(a) PEG-RGDS micropatterns (red) were fabricated using two-photon laser scanning lithography on a PEG-DA hydrogel surface (green).Fluorescently labelled HT1080s (yellow) were seeded onto surfaces and cells were observed to adhere and migrate on the PEG-RGDS micropatterns. (b) PEG-RGDS micropatterns (red) were fabricated using two-photon laser scanning lithography within an immobilized PEG-PQ hydrogel (green).Fluorescently labelled HT1080s (yellow) were photoencapsulated within a different PEG-PQ hydrogel with ubiquitous PEG-RGDS (purple). The cellularized hydrogel was immobilized directly adjacent to the patterned hydrogel, and HT1080s were observed to migrate into PEG-RGDS patterns.
