Figure 2: SSCs isolated from Tex11PM/Y mice are normal. (a) Flow cytometric analysis of the ratio of SSCs using CD146 antibody in 10-day-old WT and Tex11PM/Y testicular cells. Small black boxes represent the positive population of SSCs. (b) The ratio of CD146-positive cells in WT and Tex11PM/Y testicular cells (three mice per group) was scored. Error bar: s.d. Significance was determined by two-tailed, unpaired Student's t-test; NS: no significance. (c) Morphology of cultured WT and Tex11PM/Y SSCs. P2: passage 2. Scale bar = 100 μm. (d) Proliferation rate of WT and Tex11PM/Y SSCs during in vitro culture. The average values of three separate experiments are plotted. Error bar: s.d. Significance was determined by two-tailed, unpaired Student's t-test. (e) Expression of marker genes in WT and Tex11PM/Y SSCs. Id4 and Sohlh2 were used as undifferentiated marker genes, while Kit and Stra8 were used as differentiated marker genes. The av?erage values of three separate experiments are plotted; error bar: s.d. Significance was determined by two-tailed, unpaired Student's t-test; ***P < 0.001. (f) Immunostaining of PLZF in WT and Tex11PM/Y SSCs. Scale bar = 200 μm. (g) Scatter plot of log10-transformed average gene expression profiles. Global gene expression profiles of WT and Tex11PM/Y SSCs were obtained from RNA-seq analysis (r is the Pearson's correlation coefficient; yellow lines indicate two-fold upregulation and downregulation). (h) Heatmap correlation of SSC self-renewal genes in WT and Tex11PM/Y SSCs (r is the Pearson's correlation coefficient). WT: wild-type; Tex11: testis-expressed 11; SSCs: spermatogonial stem cells; s.d.: standard deviation; PLZF: promyelocytic leukemia zinc finger; SSC-A: Side Scatter-area; Id4: inhibitor of DNA binding 4; Sohlh2: spermatogenesis and oogenesis specific basic helix-loop-helix 2; Kit: Kit proto-oncogene; Stra8: stimulated by retinoic acid 8; Ret: ret proto-oncogene; Zbtb16: zinc finger and BTB domain containing 16; Pou5f1: POU class 5 homeobox 1; Etv5: ETS variant transcription factor 5; Gfra1: GDNF family receptor alpha 1; Foxo1: forkhead box O1; Taf4b: TATA-box binding protein associated factor 4b; T: brachyury; Lhx1: LIM homeobox 1; Bcl6b: BCL6B transcription repressor; Cxcr4: C-X-C motif chemokine receptor 4.
