Sub-cellular localization of OCT4 in EPCs was stained with a polyclonal antibody against C-terminal domain of OCT4. A. Immunocytochemistry revealed a cytoplasmic immunoreactivity for EPCs. B. NT2 cells were used as a positive control and demonstrated a primarily nuclear immunoreactivity. C. Negative control slide, all the conditions were the same as A and B, except for the elimination of the primary antibodies. a, b, and c depict the phase-contrast counterparts of A, B and C, respectively.
