Zebrafish primordial germ cell cultures derived from vasa::RFP transgenic embryos.

ABSTRACT: Although embryonic germ (EG) cell-mediated gene transfer has been successful in the mouse for more than a decade, this approach is limited in other species due to the difficulty of isolating the small numbers of progenitors of germ cell lineage (PGCs) from early-stage embryos and the lack of information on the in vitro culture requirements of the cells. In this study, methods were established for the culture of PGCs obtained from zebrafish embryos. Transgenic embryos that express the red fluorescent protein (RFP) under the control of the PGC-specific vasa promoter were used, making it possible to isolate pure populations of PGCs by fluorescence-activated cell sorting (FACS) and to optimize the culture conditions by counting the number of fluorescent PGC colonies produced in different media
