Figure 4. Co-expression of the four fluorescent proteins in the fibroblast isolated from multi-transgenic piglets.

(A) Fibroblasts isolated from the ear tissue of a representative animal (Piglet 10) observed under a confocal microscope using appropriate filters. The scale bar represents 10 µm. (B) The fluorescence intensities of the four fluorescent proteins were measured. The results are shown as mean ± S.D.
