Mobilized peripheral blood CD34+ cells express more amphotropic retrovirus receptor than bone marrow CD34+ cells.
BACKGROUND AND OBJECTIVE The increased susceptibility to gene transfer by amphotropic retroviral vectors of mobilized peripheral blood (PB) CD34+ cells compared to their bone marrow (BM) counterparts may depend, among other factors, on the level of expression of the amphotropic receptor on the progenitor cell. Using a previously described flow cytometry strategy, we have studied retrovirus bind...
متن کاملTransduction of primitive human hematopoietic cells with recombinant adenovirus vectors.
We have examined the ability of recombinant adenoviral vectors to transduce human hematopoietic cells. Our findings indicate that adenovirus readily infects a large proportion of CD34+ cells. Using adenovirus vectors that transduce either a lacZ or an alkaline phosphatase reporter gene, we observed up to 45% of total CD34+ cells infected. Upon more detailed analysis, we observed comparable leve...
متن کاملRetroviral transduction efficiency of G-CSF+SCF-mobilized peripheral blood CD34+ cells is superior to G-CSF or G-CSF+Flt3-L-mobilized cells in nonhuman primates.
Gene transfer experiments in nonhuman primates have been shown to be predictive of success in human clinical gene therapy trials. In most nonhuman primate studies, hematopoietic stem cells (HSCs) collected from the peripheral blood or bone marrow after administration of granulocyte colony-stimulating factor (G-CSF) + stem cell factor (SCF) have been used as targets, but this cytokine combinatio...
متن کاملRetrovirus-mediated gene transduction into canine peripheral blood repopulating cells.
Genetically marked peripheral blood progenitor cells were used to investigate their contribution to long-term hematopoietic reconstitution after autologous marrow and peripheral blood cell transplantation. After autologous marrow harvest and cryopreservation, canine peripheral blood progenitor cells were mobilized in three dogs by treatment with recombinant canine stem cell factor for 8 days. P...
متن کاملEfficient gene transfer into human CD34(+) cells by a retargeted adenovirus vector.
Efficient infection with adenovirus (Ad) vectors based on serotype 5 (Ad5) requires the presence of coxsackievirus-adenovirus receptors (CAR) and alpha(v) integrins on cells. The paucity of these cellular receptors is thought to be a limiting factor for Ad gene transfer into hematopoietic stem cells. In a systematic approach, we screened different Ad serotypes for interaction with noncycling hu...
