摘要：<正> In this report, we mainly covered the following aspects of "Tissue organ regeneration and replication in situ": 1) Procedures of tissue organ regeneration and replication and replication in clinical practice; 2) The discover and existence of Potential Regenerative Cell (PRC); 3) The proliferation, differentiation and regeneration law of Potential Regenerative Cells; 4) Study procedure on tissue organ regeneration and replication from PRCs in vitro based on the model of full skin organ regeneration in situ after extensive deep burns; 5) With the well-established model of tissue organ regeneration and replication and replication in vitro, set up the method and technology of searching life regenerative substances required in tissue organ regeneration and replication in situ.In this study, first, the whole human body is divided into 206 function units, which are the "Tissue Organ" in regeneration study. Then the histology foundation of tissue organ regeneration and replication in situ is set up. In order to
