SCR002 | ES Cell Marker Sample Kit

Immunofluorescence staining of human ES cell colony (hES-4) cultured upon murine feeder cells with anti-TRA-1-81 (Catalogue No. MAB4381) monoclonal antibody (green). Cells within the colony are positive for TRA-1-81 expression. DAPI staining (blue) shows the nuclei of hES cells, which are surrounded by larger nuclei of murine feeder cells.

      Description ES Cell Marker Sample Kit
      Overview The ES Cell Marker Sample Kit includes six monoclonal antibodies for the analysis of ES cell marker expression.

      Introduction:

      Embryonic stem (ES) cells are derived from totipotent cells of the early mammalian embryo and are capable of unlimited, undifferentiated proliferation in vitro (Evans & Kaufman, 1981; Martin, 1981; Morrison SJ et al., 1981). Undifferentiated mouse ES cells can be maintained for extended periods in media containing the cytokine, Leukemia Inhibitory Factor (LIF) or CHEMICON®'s proprietary ES Cell culture reagent ESGROâ (Smith AG et al., 1988; Williams, RL 1988). Upon removal of LIF from the culture medium, in vitro, the mouse ES cells differentiate into cells derived from all three germ layers. In contrast, human ES cultures require mouse fibroblasts as feeder cells and cannot be maintained with LIF for self-renewal (Thomson JA & Marshall VS 1998; Shamblott MJ et al., 1998).

      The undifferentiated state of the ES cells is characterized by high level of expression of the POU transcription factor Octamer-4 (Oct-4) (Pesce M et al., 1998). This relationship between Oct-4 and pluripotency has seen this transcription factor emerge as a marker of pluripotent stem cells. Undifferentiated human and murine pluripotent Embryonic Stem (ES) and Embryonic Carcinoma (EC) cells express Oct-4. Additionally, murine Embryonic Germ (EG) cells are also known to express Oct-4. Following stem cell differentiation, the level of Oct-4 expression decreases.

      Pluripotent stem cells can also be characterized by the expression of a number of cell surface antigens. SSEA-1, a carbohydrate antigen, is a fucosylated derivative of type 2 polylactosamine and appears during late cleavage stages of mouse embryos. It is strongly expressed by undifferentiated, murine ES cells (Solter D, 1978; Gooi HC, 1981). Upon differentiation, murine ES cells are characterized by the loss of SSEA-1 expression and may be accompanied, in some instances, by the appearance of SSEA-3 and SSEA-4 (Solter D, 1979). In contrast, human ES and EC cells typically express SSEA-3 and SSEA-4 but not SSEA-1, while their differentiation is characterized by down regulation of SSEA-3 and SSEA-4 and an up regulation of SSEA-1 (Andrews PW, 1984; Fenderson BA, Andrews PW et al., 1987). Undifferentiated, human ES cells also express the keratan sulphate-associated antigens, TRA-1-60 and TRA-1-81 (Andrews PW, Banting GS et al., 1984).

      CHEMICON®'s ES Cell Marker Sample Kit (Catalog number SCR002) contains monoclonal antibodies for the detection of the cell-surface Stage-Specific Embryonic Antigens (SSEA-1, SSEA-3 & SSEA-4), expression of TRA-1-60, TRA-1-81 antigens and Oct-4. This kit permits the phenotypic analysis of the differentiation status of ES cells by determining stem cell marker expression.
