| Outline of Final Research Achievements |
We thought that utilize DNA as biomaterial. There is an osteoplasty promotion function, and DNA has the characteristic that it becomes Jerry of the porosity if mixed with water by adjusting quantity of addition because it is porous. DNA Jerry, and it was injectable. DNA specifically couples cationic protamine in the helical structure. Protamine which let cytokine and cell adhesion protein covalently link in a cross linker to DNA electrostatically, and DNA lets scaffold materials. It was difficult to establish the technique that a conjugaion. Examined a correlation of ingredient of the additive and new osteoplasty ability from in vitro, an in vivo examination, and DNA having the environment that promotes osteoplasty. The new osteoplasty ability the bone defect on the rat skull with DNA Jerry and recognized the new bone when observed it in microCT . The cytotoxicity was relatively mild when performed HE dyeing. It was suggested that use alone acted on predominance for new bone.
