Immunofluorescent analysis of SSEA-3 (red) showing membrane staining of NCCIT cells (right panel) compared to a negative HeLa control (left panel). The cells were fixed with formalin for 15 minutes, washed, and then blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with a DyLight 650-conjugated SSEA-3 monoclonal antibody (Product # MA1-020-D650) in 3% BSA-PBS at a dilution of 1:20 and incubated for 1 hour at 37C in the dark. Nuclei (blue) were stained with DAPI. Images were taken at 60X magnification.

SSEA-3 (stage-specific embryonic antigen 3) is a cell surface antigen, expressed along with SSEA-4, TRA-1-60 and TRA-1-81 in embryonic stem cells, embryonal carcinoma cells, and induced pluripotent stem cells (iPS). In human cells, these surface markers are down-regulated during the differentiation process, while SSEA1 is absent in undifferentiated human stem cells and upregulated on the cell surface after retinoic acid mediated differentiation. Conversely, in mouse stem cells, SSEA-1 expression decreases with differentiation while SSEA-3 and SSEA-4 expression increase.
