Histological and anatomical study of the White Rooster: testis, epididymis and ductus deferens
This study was carried out to investigate the histological and anatomical description of the male genital tract in Iranian Native White Roosters (IWR). The seminiferous tubules had a dense and compact organization. An average of 12 layers of cells was seen in the seminiferous tubules epithelium. The spermatogonal cell layer showed some variation between different birds in 1-3 layers; however, t...
متن کاملDNA hypomethylation and germ cell-specific expression of testis-specific H2B histone gene.
Testis-specific H2B (TH2B) histone gene of rat is expressed during meiotic event of spermatogenic differentiation. The gene is unusual in that it has conserved the regulatory elements involved in the S phase-specific transcription of somatic H2B genes as well as the S phase-specific stabilization of histone mRNA. Genomic sequencing revealed that all analyzed CpG sites in the promoter region of ...
متن کاملIn Vitro Effect of Gold or Silver Nanoparticles on Meiotic and Postmeiotic Fractions of Rat Germinal Cells
The cytotoxicity of Au or Ag nanoparticles (NPs) on rat germinal cells was investigated in vitro. Rat germ cells separated by the STAPUT method in two different populations, pachytene spermatocytes (F5) and round spermatids (F3), were incubated (37°C, 60’-120’) with 60 μM, 125 μM, 250 μM and 500 μM of Au/Ag-NPs. Cell viability was assessed with the Eosin Y test. Au or Ag-NPs were investigated w...
متن کاملDUSP9 Modulates DNA Hypomethylation in Female Mouse Pluripotent Stem Cells.
Blastocyst-derived embryonic stem cells (ESCs) and gonad-derived embryonic germ cells (EGCs) represent two classic types of pluripotent cell lines, yet their molecular equivalence remains incompletely understood. Here, we compare genome-wide methylation patterns between isogenic ESC and EGC lines to define epigenetic similarities and differences. Surprisingly, we find that sex rather than cell ...
متن کاملHypomethylation of DNA during differentiation of friend erythroleukemia cells
DNA from mammalian cells has been shown to contain significant amounts of 5-methyl cytosine resulting from enzymatic transfer of methyl groups from s-adenosylmethionine to cytosine residues in the DNA polymer. The function of this modification is not known. We have found that DNA synthesized during chemically induced differentiation of friend erythroleukemia cells is hypomethylated, as measured...
