Abstract:
:Low in vivo transduction efficiency and safety concerns have been hurdles for effective hematopoietic stem cell (HSC) gene therapy. Here, we investigate whether the safety and efficiency of retroviral gene transfer into HSCs can be improved by using human allogeneic umbilical cord blood (UCB)-derived supplements instead of fetal bovine serum (FBS). When CD34(+) cells were cultured ex vivo in UCB-derived serum (CBS) or plasma (CBP), comparable or higher maintenance of HSCs was observed than in FBS and serum-free substitution medium (SFM) as assessed by the frequency of positive engraftment and the level of engraftment in NOD/SCID mice after transplantation of cultured cells. CBS and CBP also exhibited higher level stabilization of retroviral particles than SFM during in vitro culture of retrovirus pseudotyped with gibbon ape leukemia virus or vesicular stomatitis virus glycoprotein. Retroviral gene transfer into CD34(+) cells performed with CBS or CBP resulted in increased gene transfer into CD34(+) cells and increased transduction of reconstituted bone marrow cells compared to transfers with SFM or FBS. The increased transduction of bone marrow cells was associated with a larger number of transduced progenitors in the recipient mice. Significant oligoclonality in the transduced progenitors, as determined by ligation-mediated polymerase chain reaction, suggested efficient retroviral targeting of multiple HSCs in the CBS- or CBP-supplemented media. Combined, our results show that allogeneic UCB-derived serum or plasma is a safe and easily accessible serum supplement that can support efficient retroviral gene transfer into HSCs for the clinical-grade manipulation of HSCs.
