Gene expression profiles after lentiviral transduction

Human mesenchymal stem cells (hMSCs) were transduced using lentivirus containing the the triple fusion reporter gene fluc-mrfp-ttk. Microarray studies of hMSCs after transduction with the triple reporter genes using lentivirus were performed to study the effects of transduction on stem cell properties using an oligonucleotide human microarray. Transduced cells were sorted by FACS. Cells with high and low signals were ftacrtionated, and gene expression profiles were determined. Keywords: comparative study In this study, 8 samples were experimentally evaluated. 2 samples were used as the control without undergoing any transduction. 2 samples were transduced with the virus containing only the backbone. 2 samples were transduced with the lentivirus containing the triple reporter and has high MGFP (>10^3), while 2 samples <10^3.
