The aim of this study was to evaluate the effect of the addition of Ficoll 70 into the cryopreservation medium containing sucrose and dimethyl sulfoxide (DMSO) on rabbit spermatozoa characteristics following freezing/thawing. This large molecular weight polymer elevates the viscosity of medium and, therefore, could better protect spermatozoa during the(More)
The aim of the study was to examine sperm viability of Pinzgau bull insemination doses following longor short-term storage. Insemination doses, provided by Slovak Biological Services Inc. (Lužianky, Slovak Republic), were slow-frozen and stored in containers with liquid nitrogen for 1 18 years. The sperm samples were divided, according to the length of(More)
In this study, fresh and frozen-thawed semen of Nitra and Zobor rabbit breeds were evaluated for potential inter-breed or inter-male differences in sperm quality traits. Individual male semen from four rabbits of each breed were diluted (v:v; 1:1) in a freezing medium composed of a commercial diluent, 16% of dimethyl sulphoxide (DMSO), 4% of Ficoll 70 and(More)
This study was focused on the effect of cryopreservation on the state of actin cytoskeleton and development of rabbit pronuclear zygotes. Zygotes were collected from superovulated females and immediately used for 1) slow-freezing in a solution containing 1.5 M 1,2-propanediol and 0.2 M sucrose, or 2) vitrification in a solution containing 42.0% (v/v) of(More)
The isolation of amniotic fluid-derived mesenchymal stem cells (AF-MSCs) has been already shown in human and several other species including rabbit. However, prior to the preclinical research on various animal models it is desirable to define AF-MSCs by a panel of surface protein markers. Therefore, the aim of this preliminary study was to detect the(More)
Over the years, there has been much confusion in defining molecular markers of mesenchymal stem cells (MSCs) for other than human species due to a lack of species-specific antibodies. Therefore, the aim of our study was to define rabbit amniotic fluid-derived mesenchymal stem cells (rAF-MSCs) and to reflect upon the current identification of AF-MSCs by(More)
There is need for standardization of freezing-thawing protocol for rooster semen to minimize variability among results. Therefore, we aimed to compare effect of four different permeating cryoprotectants and two thawing temperatures (37 vs. 5°C) on sperm post-thaw motility and to analyse combined effect of the best permeating cryoprotectant (P-CPA) with one(More)
