Lentivirus transduction of bone marrow hemopoietic precursor cells with Lin-c-kit+ phenotype ex vivo using a genetic construct containing green fluorescent protein gene.

We developed a technology of labeling bone marrow precursor cells with the Lin-c-kit+ phenotype in culture by green fluorescent protein gene using a lentivirus vector. The proposed system provides effective transduction of bone marrow precursor cells and high transgene expression level in vitro (27%). The integration of the transgene into the transduced cell genome in vivo was verified by the method of splenic colonies.
