Early germ-like cells (GLCs) derived from human embryonic stem cells (hESCs) have presented new opportunities to study germ cell differentiation in vitro. However, differentiation conditions that facilitate the formation of haploid cells from the derived GLCs have eluded the field. The inability to propagate GLCs in culture is a further limitation, resulting in inconsistent rederivations of GLCs from hESCs with relatively few GLCs in these heterogeneous populations. Here we found in vitro conditions that enrich for DDX4/POU5F1+ GLCs (∼60%) and that has enabled continual propagation for >50 passages without loss of phenotype. Clonal isolation of single GLCs from these mixed cultures generated 3 GLC (>90% DDX4/POU5F1+) and 2 hESC (<0.1% DDX4+) lines that could be continually expanded without loss of phenotype. Differentiation of clonal GLC lines in serum resulted in expression of postmeiotic markers and >11% were haploid, ∼5-fold higher than previous studies. The robust clonal meiotic competent and incompetent GLC lines will be used to understand the factors controlling human germ cell meiosis and postmeiotic maturation.
