Figure 2: Immunofluorescence staining of FS101 and FS111 PC PGCs. (a) Confocal images of SSEA-1- (red) and CVH- (green) stained FS101 PGCs. (b) Higher magnification of FS101 cells (white square indicates the cells on (a)). (c) Confocal images of SSEA-1- (red) and CVH- (green) stained FS111 PGCs. (d) Higher magnification of the FS111 cells (white square indicates the cells on (c)). For nuclear staining (NS), we used TO-PRO-3 (blue). Scale bars: 25 μm (a, c) and 5 μm (b, d). PC PG cells: Partridge colour Hungarian chicken embryo-derived primordial germ cells.
