Transplantation of Ex-vivo Expanded Human Cord Blood Hematopoietic Stem Cells Expanded: Evaluation of Hematopoietic and Immunologic Reconstitution After a Reduced-intensity Conditioning Regimen

Detailed Summary

This program offers the opportunity to receive an allogeneic transplant to try to control the malignant hematologic in the absence of acceptable conventional donor and with a risk-benefit ratio equivalent to that which would be expected with a transplant from a more conventional donor. An economy of means in that this method could serve as an alternative to 2 units of placental blood transplantation. The current cost of disposal of a unit of placental blood from a bank is approximately 22000 € (Source: Biomedicine Agency, 2007 rates). The amplification process as controlled by "EFSAL" is 12000 €. Therefore, buying a unit and ex-vivo amplification is more economical. Moreover, the availability of placental blood is not infinite, and the use of one unit per patient will also save resources that can be valuable for certain groups of patients. In the longer term, methods of amplification of specific immunocompetent cells (from the fraction of CD 34 neg cells) are already being evaluated in the laboratory. They allow to consider a faster recovery, better and more targeted, including cells against the disease for which transplantation is performed.
