ac Fluorescence in situ hybridization (FISH) revealed chromosomes X, Y, and 18 in round spermatids generated from human SSCs by the 3D-I system (a), round spermatids from OA patients (b), and human SSCs of OA patients (c). Scale bars in ac = 10 μm. d FISH showed the percentages of normal chromosomes in round spermatids from human SSCs by 3D-I system, round spermatids from OA patients, and human SSCs from OA patients. The data shown in ad were presented from at least three independent experiments. e Multiplex real-time PCR displayed the expression of all eight specific STS markers from AZFa, AZFb and AZFc regions, including ZFX/ZFY, SRY, SY254, SY127, SY86, SY134, SY84, and SY255, in the round spermatids from human SSCs by 3D-I group (1st panel) and round spermatids of OA patients (2nd panel). DNA from normal human blood served as a positive control (3rd panel), and water substituting for DNA was used as a negative control (4th panel). The results shown in e were presented from three independent experiments
