Abstract
In this study, duck's feet derived collagen (DC) and demineralized bone particles (DBP) sponges were prepared by mixing both the components on the ratio of 3:1, 1:1, and 1:3. The physio-chemical properties of the sponges were examined by measuring compressive strength, porosity, SEM, etc. In vitro biological characterizations such as cell attachment, proliferation and osteogenic differentiation of the as-prepared sponges were studied by inoculating the bone marrow-derived stem cells (BMSC) in ratio-specific DC/DBP sponges followed by SEM, MTT, ALP, RT-PCR & histological analysis by staining. We found that the 1:1 DC/DBP sponges displayed superior osteogenesis, thus can be envisioned as a potential, biomaterial for regeneration of bone.

본 연구에서는 오리발 콜라겐(duck's feet derived collagen, DC)과 탈미네랄화된 골분(demineralized bone particles, DBP)을 3:1, 1:1, 1:3 비율로 혼합하여 스펀지를 제조하였다. 제조한 스펀지의 특성분석을 위해 압축강도, 다공성, SEM 등을 측정하였으며, 골수 유래 줄기세포(BMSC)를 비율별 DC/DBP 스펀지에 파종하여, 세포 부착, 증식 및 골 분화를 확인하고자, SEM, MTT, ALP, RT-PCR 및 조직학적 염색을 통한 분석을 실시하였다. 그 결과, 1:1 DC/DBP 스펀지에서 골 분화 효과가 우수한 것을 확인하였으며, 이를 골 재생을 위한 생체재료로 활용할 수 있을 것으로 기대된다.

Keywords: duck's feet derived collagen (DC); demineralized bone particle (DBP); bone marrow stem cells (BMSc) osteogenesis
