Human cord blood stem cells (CBSC) (Figure) are known to contain the most premature hematopoietic stem cells as well as mesenchymal stem cells. CBSCs have been clinically used as the source of hematopoietic stem cell transplantation for severe hematologic diseases like leukemia, and they are now widely used for research purposes in the medical and biological studies of regenerative medicine, drug development, epidemiology, infection, genetics and environmental studies.
This project provides fresh or frozen cord blood stem cells that are not suitable for transplant purpose and transferred from three cord blood banks of the Japan Cord Blood Bank Network (Tokyo, Tokai University and Hyogo CB Banks) with written consent to researchers through the RIKEN BRC.
