Figure 4From: Molecular markers to characterize the hermaphroditic reproductive system of the planarian Schmidtea mediterraneaGenes upregulated in the sexual planarian that are expressed in the testes. (A-H) Single confocal sections showing FISH for genes (green) expressed in the testes. Nuclei are counterstained with DAPI (grey). (A-D) msy4, thmg-1, pde, and plastin transcripts are expressed in all germ cell types in the testes except mature sperm. (E) tkn-1 transcripts are enriched in spermatocytes. (F) tplh transcripts are enriched in spermatocytes and spermatids. (G and H) pp2 and pka transcripts are enriched in spermatids. Scale bar: 40 μm.Back to article page
