Identification and characterization of germ cell genes expressed in the F9 testicular teratoma stem cell line.

ABSTRACT: The F9 cell line, which was derived from a mouse testicular teratoma that originated from pluripotent germ cells, has been used as a model for differentiation. However, it is largely unknown whether F9 cells possess the characteristics of male germ cells. In the present study, we investigated spermatogenic stage- and cell type-specific gene expression in F9 cells. Analysis of previous microarray data showed that a large number of stage-regulated germ cell genes are expressed in F9 cells. Specifically, genes that are prominently expressed in spermatogonia and have transcriptional regulatory functions appear to be enriched in F9 cells. Our in silico and in vitro analyses identified several germ cell-specific or -predominant genes that are expressed in F9 cells. Among them, strong promoter ac
