Re-establishment of BTB in the recipient testes after repaired SSC transplantation. A, B Distribution of N-cadherin and JAM-A (all in green) were found to be different in different tubules, depending on the status of spermatogenesis and the differentiation status of repaired SSCs. Abnormal distribution of these proteins in empty tubules devoid of germ cells (a and g) was obviously noted and gradually returned to normalcy as showed in normal wild type control testis (e and k) following the appearance of spermatocytes (b and h), round spermatids (c and i), and elongated spermatids (d and j). Spermatocytes were labeled by anti-SCP3 antibody (red), and round spermatids and elongated spermatids were identified by the corresponding nucleus shape (blue). There were no germ cells in panels a, a’, f, g, g’, and l. The boxed areas in a–d and g–j are magnified and shown in a’–d’ and g’–j’. Scale bar = 50 μm in a–l and 10 μm in a’–d’ and g’–j’
