This invention being preparation possible from the cell where it picked from the patient regardless of to age formation, has had the regenerative capacity of the bone tissue which is superior, it is to offer the cell formulation which is effective to the regeneration of bone tissue. The not yet amount ossification bud cell which is obtained the not yet amount ossification bud cell which is obtained from the alveolus bone, the enzyme after treating the especially alveolus bone, by culturing has had the regenerative capacity of the bone tissue which is superior, as the cell formulation for bone tissue regeneration it is possible to utilize.本発明は、年齢層に関係なく患者から採取した細胞から調製可能であって、優れた骨組織の再生能を有しており骨組織の再生に有効な細胞製剤を提供することである。歯槽骨から得られた未分化骨芽細胞、特に歯槽骨を酵素処理した後に培養することにより得られる未分化骨芽細胞は、優れた骨組織の再生能を有しており、骨組織再生用の細胞製剤として利用することができる。
