Transduction of CXCR4 in mesenchymal stromal cells (MSCs) with reporter genes. (a) Fluc activity and quantitative bioluminescent imaging (BLI) data of CXCR4-transduced MSCs with different cell numbers. (b) Enhanced green fluorescent protein (eGFP) expression analysis by confocal microscopy imaging and (c) CXCR4 mRNA expression analysis by RT-PCR. (d) Protein expression of CXCR4 by Western blot analysis.
