Proliferative activity of PA gels. The 8mM PA gels containing 5000 RINm5f cells/uL were assayed for cell proliferation by brdU incorporation and immunostaining followed by visualization of brdU+ cells (red) and total cells (DIC, grey) using confocal microscopy (a: control PA gel; b: GLP-1-mimetic PA gel). The GLP-1-mimetic PA gel at 10% or 100% with or without cytokines produces significantly higher proliferation than exendin-4 or control PA (c; error bars: 95%CI; * p<0.05, ** p<0.01 vs. control PA gel).
