    摘要: A demineralized bone matrix (DBM) or other matrix composition is provided that has been stabilized by lowering the pH of the composition, reducing the water content, adding water substitutes, and/or increasing the amount of deuterated water present in the composition in order to reduce the activity of endogenous degrading enzymes such as proteases. A hydrated form of a stabilized DBM composition may be stable up to a year at room temperature at acidic pH. The acidified DBM compositions may be further stabilized by the addition of a stabilizing agent such as deuterated water, water substitutes, polymers, protease inhibitors, glycerol or hydrogels.

    摘要: A malleable implant for implantation into living tissue is prepared having access means for cells into the interior of the implant. The implant is capable of being deformed under pressure required to insert the implant into an implant site. The access means can be hollow or solid. The solid comprises a material that more rapidly resorbs in vivo than the malleable implant to provide channels, or comprises a mechanically weak material that fractures under force at an implant site to produce channels or cracks. The access means may be inserted in the malleable implant at an implant site. A multilaminar structure may be formed having layers of malleable implant and layers of access means, or the access means may be heterogeneously distributed throughout the malleable implant. A kit can contain a powder such as calcium phosphate for making a paste implant material, and an access means insertable into the paste.
