Detection of potential morphological changes and fluorescence of Lowland Anoa derived cells following gene introduction using recombinant viral vectors. a Cell morphology of 4 cell lines; wild type; EGFP, cell line transduced with EGFP expressing virus, K4D, cell line transduced with mutant CDK4 and Cyclin D; K4DT, cell line transduced with cyclin D1, mutant CDK4 and TERT. b Detection of fluorescence in cells transduced with the recombinant lentiviral vector expressing enhanced green fluorescence protein (EGFP). Note that the fluorescence gene was introduced into the cells around 50 %. The morphologies of cells were obtained after 72 h from transduction with recombinant viral vectors
