Abstract

The invention discloses a kit for verifying endodontium mesenchymal stem cells. The kit comprises a flow phenotype detection reagent set, cell fixation liquid, an ordinary culture medium, an adipogenesis induction and detection reagent set, an osteogenesis induction and detection reagent set and a chondrogenesis induction and detection reagent set. Usually, conventional osteogenesis induction and adipogenesis induction need about 24 days, consumed time is long, and induction efficiency is low; by the kit, the time for osteogenesis induction and adipogenesis induction is shortened to 18 days, induction efficiency is improved, and induction time is shortened; conventional flow detection mainly aims at universal surface markers of mesenchymal stem cells, but the endodontium mesenchymal stem cells have positively-expressed surface markers CD146 which are different from the surface markers of other mesenchymal stem cells; CD146 antibodies are added into the kit, and accordingly, accurate verification results can be acquired.

Description

technical field [0001] The invention relates to a kit, especially a kit for identifying dental pulp mesenchymal stem cells. Background technique [0002] At present, more and more studies are using dental pulp-isolated mesenchymal stem cells for clinical use, and the development prospects of dental pulp mesenchymal stem cells are getting better and better. The International Society for Cell Therapy (ISCT) stipulates that the identification of mesenchymal stem cells includes three aspects: morphology, flow phenotype, and ability to induce differentiation. Traditional mesenchymal stem cell identification methods are relatively mature, but the process of induction and differentiation takes a long time, and the induction efficiency is low, which affects the final cell identification results. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kit for identifying dental pulp mesenchymal stem cells which improves the in...
