제목 Sustained Release of BDNF using Temperature Sensitive MPEG-PCL Hydrogels
초록 Methoxy poly(ethyleneglycol) (MPEG)-b-poly(ε-caprolactone) (PCL) diblock copolymer was synthesized by ring-opening of ε-caprolactone (ε-CL). The temperature sensitive behavior of the prepared MPEG-PCL diblock copolymer was examined in aqueous. The MPEG-PCL diblock copolymer was dissolved in water at 80 ℃. The formed sol became gel at 31 ℃ as the temperature increased. On further increase of the temperature, the gel changed to sol at 52 ℃. This indicates the diblock copolymer solutions at room temperature can form gel at body temperature. Brain derived neurotrophic factor (BDNF) loaded MPEG-PCL diblock copolymer solution was prepared to observe the release behavior of growth factor by ELISA. The release profile of BDNF in MPEG-PCL gel showed the sustained release for 20 days. So we confirmed that MPEG-PCL diblock copolymer solutions is useful as BDNF carriers.
