The stage-specific embryonic antigen 1 (SSEA-1) is a cell marker of primordial germ cells (PGCs). In the present study, it is shown that isolation and purification of PGCs from 8.5-11.5 days post coitum (dpc) embryos can be achieved by a immunomagnetic cell sorting method using SSEA-1 antibody-conjugated magnetic beads, and then the sorted PGCs can be used for long-term culture under strict culture conditions to derive embryonic germ (EG) cell lines. Five independent EG cell lines with male karyotypes have been established. They show both a strong alkaline phosphatase activity and expression of the SSEA-1 antigen, and are karyotypically stable with a modal number of chromosomes in more than 80% of the cells. One of the EG cell lines from 8.5-dpc embryos produced chimeras after injections of the cells into 8-cell host embryos. These procedures could provide a useful and simple method for isolation of undifferentiated cells from a heterogeneous cell population and for establishment of embryo-derived stem cell lines.

D018189 Immunomagnetic Separation A cell-separation technique where magnetizable microspheres or beads are first coated with monoclonal antibody, allowed to search and bind to target cells, and are then selectively removed when passed through a magnetic field. Among other applications, the technique is commonly used to remove tumor cells from the marrow (BONE MARROW PURGING) of patients who are to undergo autologous bone marrow transplantation.
