Obstruction of the vas deferens alters protein secretion by the rat caput epididymidal epithelium in vivo.
Obstruction of epididymal lumen fluid flow alters the intraluminal environment and potentially changes epididymal epithelial cell function when those functions are dependent on intraluminal regulatory molecules. This investigation tested the hypothesis that obstruction of the rat vas deferens alters caput epididymidal protein synthesis and secretion In vivo. Adult male rats were subjected to va...
متن کاملComparison of four methods to evaluate sperm DNA integrity between mouse caput and cauda epididymidis.
It is well known that transit through the epididymis involves an increase in the compaction of sperm chromatin, which acquires fully condensed status at the caput epididymidis. The purpose of this study was to compare the terminal deoxyribonucleotidyl transferase-mediated dUTP nick end-labelling (TUNEL) assay, the comet assay, the sperm chromatin structure assay (SCSA) and the sperm chromatin d...
متن کاملMouse spermatid nuclei can support full term development after premature chromosome condensation within mature oocytes.
The nucleus of round spermatids, the earliest haploid male germ cells, can participate in the formation of normal zygotes when incorporated into activated oocytes. In this study, we injected mouse round spermatids into homologous mature oocytes that were kept arrested at metaphase II to induce premature chromosome condensation (PCC) of the spermatid nuclei. After full condensation of the sperma...
متن کاملPotential of Mouse and Human Embryonic Fibroblasts to Support Mouse Embryo Development Following Exposure to Laboratory Temperature
Purpose: Present study was designed to evaluate the potential of co-culture systems to overcome deleterious effect of exposure of mouse 2-cell embryos to low temperature. Materials and Methods: 2-cell embryos were flushed from oviduct of super ovulated NMRI mice into HTF medium with 15% BSA. After washing 3 times with HBSS and with 15% BSA, embryos were exposed to laboratory temperature (LT) (...
متن کاملSperm-carried RNAs play critical roles in mouse embryonic development
Recently, numerous studies have reported that the mature sperm contains both coding and non-coding RNAs and the sperm delivers some RNAs to the oocyte at fertilization. However, the functions of the RNAs carried to the oocyte by sperm at fertilization in embryonic development remains a mystery. In this study, the mature spermatozoa were treated with lysolecithin, pronase and RNases (RNase A and...
