Fig. 3: Flamenco exon and intron expression patterns.

a flamenco (flam) expression detected in the testis using a 1st exon probe. Expression is cytoplasmic. b flam expression detected using an intronic probe. Expression is primarily nuclear (Y-loop-like in spermatocytes). c flam transcripts detected both on (white arrows) and trailing (green arrows) elongated spermatid nuclei (magenta). d flam transcripts in secretory cells and lumen of accessory glands. Scale bars = 20 µm.
