Figure 6. Differentially expressed LncRNAs in human spermatogonia between OA and NOA patients. (A) The cluster heat map showed lncRNAs with an expression change fold ≥2 from microarray data (p<0.025) in human spermatogonia from OA patients compared with NOA patients. (B) Scatter plot illustrated the differentially expressed lncRNAs with an expression change fold ≥2 (p<0.025) in human spermatogonia from OA patients compared with NOA patients. (C–F) Real-time qPCR revealed the different expression levels of XIST, CDKN2B-AS1, MAL2 and CASC7 in human spermatogonia between OA and NOA patients. * denoted statistically significant differences (p< 0.05) in human spermatogonia between human OA and NOA patients.
