    Demineralized bone particle(DBP) that affects to cell proliferation and differentiation has been used to clinical trial as natural material. hyalunonic acid(HA) called natural moisturizer can be used as biomaterials. In this study, we tried to design and characterize novel DBP-HA sponge. DBP-HA sponge were prepared by freeze-drying method after addition of 1 wt% HA solution into fabricated DBP sponge. Sponge was crosslinked with 1-ethyl-(3- 3-dimethyl aminopropyl) carbodiimide hydrochloride(EDC) solution with 50 mM concentration for 24 hrs and lyophilized. We seeded cells in DBP-HA sponge. Cellular attachment was assayed by 3-(4,5-dimethylthiazole-2-yl)- 2,5-diphenyltertazolium-bromide(MTT) test. DBP-HA sponges were characterized by scanning electron microscopy, fourier transeform infrared spectrometer and water ubsorption ability. We demonstrated presence of HA in DBP-HA sponge from C-O functional group observed by the FT-IR analysis. Moreover, we confirmed high water uptake ability and high cell viability in DBP-HA sponge. Therefore, we could expect that DBP-HA scaffolds are applicable for the tissue regeneration.
