dc.description.abstractThe fusion of embryonic stem (ES) cells with differentiated somatic cells is an approach that reverses a somatic cell nucleus to a state of pluripotency. the resulting ES-somatic cell hybrids (ES-SCH) retain most of the properties of ES cells: differentiate into multiple cell types and have the ability to produce embryoid bodies (EB) and chimeras. However, it is still unknown whether ES-SCH will be able to complete the differentiation into germ cells (GC) in vitro similar to ES cells. Here, we show that near diploid ES-SCH, obtained by the fusion of mouse ES and spleen cells, were able to differentiate in vitro into presumptive GC. Differentiation of ES-SCH was induced through EB formation and by the addition of retinoic acid. Presumptive GC obtained reacted positively with anti-EMA, Vasa, Fragilis and Dazl antibodies and expressed GC-specific genes, such as Vasa, Stella, Dazl, Piwii 2, Tex 14, Bmp8b, Tdrd 1 and Rnf17. Fluorescent in situ hybridization analysis indicates chromosome reduction in the GC-like cells. Expression of meiotic and postmeiotic GC-specific genes such as Haprin, Acrosin, Scyp1, Scyp3 and Stra-8 were also detected. Transmission electron microscopy confirmed ES-SCH differentiation into presumptive GC. the presence of several autosomes and the X chromosome originated from the somatic'' partner did not prevent ES-SCH differentiation towards presumptive GC. Overall our study suggests an interesting in vitro model, which allows the study GC differentiation in reprogrammed somatic cells. (C) 2009 International Society of Differentiation.
