제목 Micropatterning of Cells on MMA-based Amphiphilic Nonfouling Surface and its Application
초록 We investigated the stability of the cell patterns by periodically observing the cells by phase contrast optical microscopy for a month. For square FN patterns, the cell patterns were stable for at least two weeks, and a few connections of adjacent cells were observed after that time. However, some cells were confined to the underlying FN features even after a month. We believe that increasing the interfeature spacing for isolated features like squares should solve this problem. For the stripe patterns, the cells were confined to the FN pattern for up to a month. Compared with the use of bovine serum albumin (BSA) as a cell-repellent background, on which the cell patterns could only be maintained for 1 h, with no pattern remaining after 4 h incubation in serum-containing medium, and oligoethylene glycol-terminated thiols, whose application is limited to gold, the comb polymer’s applicability to diverse substrates such as polymers and metals (e.g., gold) as well as its ability to confine cells to the underlying cell-adhesive pattern for long periods of time indicates its potential to be a broadly suitable template for both short- and long-term cell patterning in a physiological milieu.
