Polymer microarray analysis using pancreatic CSCs to identify niche-mimicking polymer materials. A Twenty-six hit polymers whose CSC growth rate was over 3 and the four control polymers. Polymer names are listed on the x-axis in the order of “CSC growth rate”, and CSC specificity values were shown in the secondary axis. All fluorescent intensity values were listed in Additional file 2. PA: Polyacrylate, PU: Polyurethane. B Fluorescence images of cells at 18 and 48 h after culturing on the hit and control polymers. Scale bar = 200 μm. C Chemical structures of the identified hit and control polymers
