A Synthetic Polymer, Poly(2-methacryloyloxyethyl phosphorylcholine-co-n-stearyl methacrylate), Stimulates Insulin Release from RINm5F Insulinoma Cells

抄録

A water-soluble phospholipid-like polymer, poly(2-methacryloyloxyethyl phosphorylcholine-co-n-stearyl methacrylate) (PMC₁₈, average molecular weight = 4.3×10⁴), at a concentration (0.5–5 mg/ml) showing no inhibition of cell proliferation, stimulated insulin release from RINm5F rat insulinoma cells in a concentration- and time-related manner. But poly(2-methacryloyloxyethyl phosphorylcholine) and other synthetic phospholipid-like polymers failed to stimulate insulin release.
