초록
항산화와 항염증으로 잘 알려진 헤스페리딘은 디스크 재생을 위해 효과적인 지지체로 제작하기 위해 사용하였다. 지지체는 poly(lactide-co-glycolic acid) (PLGA)에 헤스페리딘(0, 3, 5, 10%)을 첨가하여 염 침출법으로 제작하였고, 섬유륜 세포(AF)를 파종한 후 세포의 변화를 연구하였다. SEM, WST 그리고 RT-PCR 분석을 통해 세포의 부착과 증식, 세포의 표현형 분석을 실시하였다. 또한 면역조직화학염색을 통하여 AF세포의 생체 내 거동을 확인하였다. 그 결과, 5% 헤스페리딘이 함유된 PLGA 지지체가 가장 좋은 세포의 형태와 생체 적합성을 보여, 디스크 재생을 위한 지지체로서의 활용 가능성을 확인하였다.
Hesperidin, a well-known antioxidant and anti-inflammatory agent, was smartly used for designing efficient scaffolds for disc regeneration. The scaffolds were synthesized via a salt-leaching method by adding hesperidin (0, 3, 5, & 10%) to poly(lactide-co-glycolic acid) (PLGA) followed by a cellular behaviors study by seeding annulus fibrosus (AF) cells. The cellular adhesion, proliferation and phenotypes were further evaluated by SEM, WST and RT-PCR, respectively. Additionally, AF cell behavior was studied by immunohisto-chemical staining in vivo. Results showed that PLGA scaffold with 5% hesperidin are best suited for disc regeneration, showing good cellular morphology and biocompatibility.
