Ex vivo expansion of cord blood hematopoietic progenitors is an attractive way to prepare a sufficient number of transplantable cells for cord blood transplantation in adult patients. The expanded cells need to have genetic stability. Karyotypic analysis of the expanded cells from cord blood CD34+ cells by 7-day culture with stem cell growth factor, interleukin (IL)-3, IL-6, granulocyte colony-stimulating factor, and erythropoietin was performed. Several-fold increases in total cell number and CFU-GM were 186.7 ± 62.1 and 27.1 ± 9.4 (mean ± standard deviation of data from 6 samples), respectively. Karyotypes were analyzed in 600 expanded cells in total, and all of them showed normal karyotypes. This observation suggests that multifactor supported expansion of cord blood cells may not induce karyotypic abnormality, although a limited number of ex vivo expanded cells were tested.
