ABSTRACT
N-acryloylmorpholine (NAM) was photo-polymerized to produce the homopolymer poly(N-acryloylmorpholine) (PNAM). PNAM behaves as a physical hydrogel in aqueous solvents, doubling its dry weight over a 2 h period before undergoing dissolution following a second order exponential decay profile. In vitro cellular experiments using mouse myoblasts showed that PNAM acts as an effective spatial cell barrier for 38 h, with slow migration of cells into the PNAM area occurring between 45 and 73 h after cell seeding. At 80 h myoblasts fully occupied the area initially blocked by PNAM. Immunofluorescent staining of myoblasts adjacent to PNAM showed normal cytoskeletal structure and well developed focal adhesions indicating limited PNAM toxicity. This study shows that PNAM is an easy to synthesize physical hydrogel that acts as a temporal and spatial barrier to cell adhesion.
