Fig. 2From: Transcriptome analysis reveals differentially expressed genes associated with germ cell and gonad development in the Southern bluefin tuna (Thunnus maccoyii)Southern bluefin tuna gonad histology. SBT ovary sections in maturation stages 1 and 3 are presented in images a and b, respectively. SBT testis in maturation stages 2 and 3 are presented in images c and d, respectively. Different spermatogonial germ cell populations are distinguished in images c–d: Sg – Spermatogonia types A and B (ASG/BSG), Sc – Spermatocytes, Sd – Spermatids, Sz – Spermatozoa. Sections were stained with H&E staining. 20x objective was used in all images. Detailed information regarding the image acquisition is provided in the ‘Methods’ sectionBack to article page
