Sentence examples for microscopy on testis from inspiring English sources

To study the distribution within the cells naturally expressing Sun3 (i.e. spermatids) we performed immunofluorescence microscopy on testis paraffin sections.

To this end, we performed immunofluorescence microscopy on testis paraffin sections using antibodies against yet known mammalian KASH proteins: Nesprins 1, 2, 3 and 4. Whereas Nesprins 2 and 4 were not detectable in any postmeiotic stage (not shown), Nesprins 1 and 3, both are actually present in spermatids as evidenced by immunofluorescence analysis (Figure 4A,B; see also below).

Defects in acrosome formation can be detected using a combination of PAS staining of testis section, and transmission electron microscopy on testis and sperm samples.

To find out whether Smc6-containing heterochromatin regions in non-meiotic germ cells also embed the centromeres, we performed co-immunofluorescence microscopy on testis section using an antibody against Smc6, CREST-serum and DAPI.

Because the timing and expression pattern of Smc6 in differentiating spermatogonia appears similar to the gradual development of heterochromatin during spermatogenesis, we performed co-immunofluorescence microscopy on testis sections using antibodies against Smc6, the heterochromatin marker H3K9me3 and DAPI as DNA-stain to determine specific cell types by nuclear morphology and tubular context.

Early stages of sperm development appear normal by standard phase-contrast microscopy of testis squash preparations (data not shown).

Using immunohistochemistry on testis sections and fluorescence-based microscopy on intact live seminiferous tubules, we show that CTCFL is only transiently present during spermatogenesis, prior to the onset of meiosis, when the protein co-localizes in nuclei with ubiquitously expressed CTCF.

More progressive effects on testis weight and histopathology were observed in the Fischer rats.

Until about 2010, research on sex determination (the differentiation of the embryonic bipotential gonad into a testis or an ovary) focused primarily on testis development (Uhlenhaut et al. 2009; Richardson 2013).

We performed new expression analyses on testis and brain tissue from XL, XB, and HXLXB.

Treatment had no obvious effect on testis and epididymis anatomy.
