Characterization of HA-F127. (A) The appearance of 0.5%, 1.0%, 1.5%, 2.0%, 2.5%, 3.0%, 3.5%, 4.0% HA-F127. It was obvious that 0.5%, 1.0%, 1.5%, 2.0% HA-F127 did not solidified; (B) The gelation times of 2.5%, 3.0%, 3.5%, 4.0% HA-F127; (C) The TEM of 2.5%, 3.0%, 3.5%, 4.0% HA-F127; (D), (E), (F), and (G) The elastic modulus, swelling ratio, remaining ratio and release of 2.5%, 3.0%, 3.5%, 4.0% HA-F127, respectively. (H) The RMSCs proliferation in under different concentration of HA-F127.
