Title: Concise review: Umbilical cord derived mesenchymal stem cell bank
Abstract: Mesenchymal stem cells (MSCs) are the most promising stem cells for clinical applications. MSCs are widely used in disease treatment in some different countries. Recently, some MSC banks are developed to cryopreserve MSCs from umbilical cord tissues, adipose tissues and bone marrow. This review aims to discuss some techniques, some advantages as well as disadvantages of umbilical cord derived mesenchymal stem cell banking (UCMSCB). From 2010 to date, there are more than 10 UCMSCBs established in the world. There are two methods to isolate UCMSCs including tissue culture and single cell culture. Then they are cryopreserved in the liquid nitrogen for long time. Although, UCMSCBs can provide more the choice to store the MSCs from umbilical cord, allogenic MSC transplantation with high efficacy in disease treatment suggests that UCMSCBs should change the with new approaches to use the cryopreserved samples.
