The invention discloses a placenta stem cell bank construction method and a placenta tissue resuscitation method, and relates to placenta stem cell bank construction methods. The placenta stem cell bank construction method comprises the following steps: after non-bacterial cleaning treatment to placenta tissues of at least three parts, the steps of tissue peeling, further sterilizing, shearing to be thin, protecting using a refrigerant, programmed freezing, cryogenic temperature temporary storage, long term storage with nitrogen canisters, and the like are carried out, and the placenta tissue with biological activities can be preserved for a long term. The placenta tissue preserved through the method can be used for the construction of a stem cell bank, resuscitation, enzymic digestion, cultivation, expansion, quality inspection and the like are performed after selective tissue part resuscitation according to required cell types, so as to obtain placenta amniotic membrance epithelial cells, placenta amniotic membrance mesenchyme, placenta chorion mesenchymal stem cell, placenta decidua serotina mesenchymal stem cells and the like. The method provided by the invention has the advantages that operation steps are simplified, manual intervention errors are reduced, the efficiency is improved, more stem cell resources are preserved, and a basis is provided for further personalized stem cell customization.
