Abstract: | The pluripotent mouse embryonal stem cell line BLC 1 and two transformants derived from it by DNA transformation (T1 and T2/K26) as well as the blastocyst-derived cell line BLC 3 were tested for the presence of cell surface antigens recognized by the monoclonal antibodies ECMA-7, anti-SSEA-1 and M 1/22.25, and intermediate filament proteins labeled by the monoclonal antibodies TROMA 1 and TROMA 2 using a three-step indirect immunofluorescence technique. According to present concepts and in agreement with previous data (Wobus et al., 1984a), the results obtained indicate that BLC 1, T1 and T2/K26 are undifferentiated embryonal stem cells, and BLC 3 is an endoderm-like cell line. |
