Abstract

The human glucocerebrosidase (GC) gene has been expressed in the progeny of murine hematopoietic stem cells following transduction of marrow with a retroviral vector (G2) containing the human GC cDNA. Murine marrow was transduced via co-cultivation following prestimulation in the presence or absence of recombinant IL-3 and IL-6. A high rate of gene transfer and expression (95%) was demonstrated in primary day 12 CFU-S foci following bone marrow transplantation (BMT) of G2-transduced marrow into lethally irradiated syngeneic recipient mice. Immunoreactive human GC protein was also documented in the CFU-S foci. Primary recipient mice were examined 4-6 months following BMT. A higher rate of gene transfer (87%) was seen in hematopoietic organs of recipients of prestimulated donor marrow compared with organs from initially unstimulated marrow (25%). A high rate of expression of human GC was also documented in the prestimulated organs (50%) when compared with the unstimulated group (25%). Secondary BMT was performed using marrow from the long-lived primary recipients. The human GC gene was present in 88% of secondary day 12 CFU-S foci examined in the prestimulated group versus 23% in the unstimulated group. Expression of the human GC gene was documented in secondary day 12 CFU-S foci, providing strong evidence of initial hematopoietic stem cell transduction.
