a Proliferation rate of MSCs cultured on TCPS as a reference, UV unexposed PMAn film (PMAn-UV), and UV exposed PMAn film (PMAn + UV) in serum contained culture media at day 5 and 7. MSCs were seeded at a density of 2 × 103 cells/cm2 at first (white box). b-d The optical microscopic images of MSCs cultured on three different substrates, TCPS, PMAn-UV, and PMAn + UV at day 7
