Figure 7From: Seminiferous tubule transfection in vitro to define post-meiotic gene regulationEYFP expression (green) in seminiferous tubules 24 h after transfection with an EYFP reporter plasmid driven from (A) the proacrosin gene promoter, (B) the protamine gene promoter, and (C) the SP-10 gene promoter. All nuclei are labelled with DAPI (blue), and mature sperm acrosomes are labelled using PNA (red).Back to article page
