23 Jul Injectable tissue engineering building method for regenerating dental pulp dentin
Abstract
The invention discloses an injectable tissue engineering building method for regenerating dental pulp dentin. The method comprises the following three steps: preparation of an injectable hyaluronic acid gel scaffold material, separation and cultivation of mesenchymal cells of tooth germs, building of cells and injectable scaffold material compounds in different microenvironments, material preparation of implants and histological detection. According to the method disclosed by the invention, the third generation of mesenchymal cells of tooth germs are seed cells for regenerating dentin pulp sample structures by using a tissue engineering method; TGF-beta1 plays a crucial role in building of the dentin pulp sample structures; meanwhile, the hyaluronic acid gel can be an injectable scaffold material and is suitable for injectable dental tissue engineering; the third generation of mesenchymal cells of tooth germs, the TGF-beta1 and the hyaluronic acid gel are combined and injected into an emedullated dental pulp cavity to build the injectable tissue engineering; thus, in situ regeneration of a dentin-pulp complex sample structure can be realized under the micro-trauma condition, and a new possibility is provided for in situ and physiological regeneration of the dentin-pulp complex in clinic.
