23 Jul Biology source type calcified-layer containing cartilage tissue engineer bracket
Abstract
The invention discloses an engineering bracket made of biogenic cartilage tissue containing calcified layer bone. The bracket is a multi-layer structure, with one side of a substrate which contains at least one layer of acellular component and mainly takes II-typed collagen as main, the other side of subchondral bone structure containing at least one layer of acellular component and the middle of a calcified layer structure containing one acellular component. The calcified layer acellular structure removes the cell component structure and has the functions of normal calcified layer structure such as connection, stress decentralization, and separation of micro-environment between cartilage and subchondral bone. The engineering bracket is especially suitable for guiding the regeneration of bone and cartilage tissues and is beneficial for restoring the missing or destroyed bone and cartilage in vivo.
