Ribosomal RNA in mouse spermatocytes
Experimental Cell Research, 1974Abstract Several earlier autoradiographic observations have reported the absence or the very low rate of nuclear incorporation of RNA precursors in male gametocytes. The problem of ribosomal RNA synthesis in mouse spermatocytes was approached biochemically by using ionizing radiation which at low doses selectively destroys spermatogonia without ...

Flow Cytometry of Murine Spermatocytes
Current Protocols in Cytometry, 2015AbstractProtocols for purification of murine male germ cells by FACS based on Hoechst 33342 (Ho342) dye staining have been reported and optimized. However, the protocols are often challenging to follow, partly due to difficulties related to sample preparation, instrument parameters, data display, and selection strategies.

Spermatocytic Seminoma Associated with Rhabdomyosarcoma
American Journal of Clinical Pathology, 1990A case of spermatocytic seminoma intimately associated with rhabdomyosarcoma is reported. The patient, a 51-year-old man, presented with a two-year history of right-sided testicular enlargement. Orchiectomy was performed, and a large testicular tumor was excised.

Anaplastic variant of spermatocytic seminoma
Human Pathology, 1996Four examples of spermatocytic seminoma with a predominant anaplastic component occurred in men 33 to 43 years of age, without histories of cyptorchidism. The seminomas presented with painless testicular masses recognized 3 to 18 months before orchiectomy.

Multiple complexes in human spermatocytes
Chromosoma, 1978Multiple complexes develop during metaphase I in normal human spermatocytes. Usually they form two separate bodies about 1 micron in diameter, composed of tripartite units and a denser matrix. The tripartite units are structurally identical to the components of the central space of synaptonemal complexes (SCs).

Spermatocytic seminoma: An immunohistochemical study
Human Pathology, 1994Spermatocytic seminoma (SS) is an unusual germ cell tumor that behaves in an indolent fashion. Because orchiectomy alone in adequate treatment, it is important to distinguish SS from classic seminoma and other germ cell tumors. Light microscopic distinction usually is possible; however, occasional cases of SS exhibit atypical features, including the ...

Anaplastic variant of spermatocytic seminoma
Pathology - Research and Practice, 2007We report a case of a 56-year-old male with an anaplastic variant of spermatocytic seminoma of the left testis. Grossly, the tumor measured 10 x 7.5 x 6.5 cm and consisted of soft grayish-white tissue, which varied from fleshy to gelatinous with formation of some pseudocysts.

Immunofluorescence Analysis of Human Spermatocytes
2009New immunofluorescence techniques allow visual identification of human cells in various stages of meiotic prophase. Antibodies to the synaptonemal complex, the centromere and sites of recombination allow these stages of meiotic prophase to be identified.

Microinjection into crane-fly spermatocytes
Biochemistry and Cell Biology, 1993We were successful in microinjecting fluorescently labelled material into crane-fly spermatocytes. In our experiments, we obtained four results. (i) In most attempts, the membrane stretched around the micropipette and prevented entry of fluorescent material, even when the micropipette appeared to be pushed completely through the cell.
