Multiplication of hematopoietic progenitor cells ex vivo and to compositions of hematopoietic growth factors

摘要

Patients suffering from certain types of cancer are treated by high-dose chemotherapy. In order to allow a recovery a process for the ex vivo expansion of peripheral blood progenitor cells is described, wherein CD 34+-cells are enriched and cultivated in a medium comprising IL-1, IL-3, IL-6, EPO and SCF. The ex vivo expanded peripheral blood progenitor cells can be administered to cancer patients after chemotherapy.
