In our study we investigated the effect of maternal restraint stress on preimplantation embryo development using a mouse model. We exposed hormonally stimulated (superovulated) and unstimulated (i.e. spontaneously ovulating) mouse females to restraint stress for 30 min three times a day during the preimplantation period. The stress exposure caused(More)
We found retardation of preimplantation embryo growth after exposure to maternal restraint stress during the preimplantation period in our previous study. In the present study, we evaluated the impact of preimplantation maternal restraint stress on the distribution of inner cell mass (ICM) and trophectoderm (TE) cells in mouse blastocysts, and its possible(More)
This study investigated the effects of maternal body condition on oocyte quality and zygote production. Additionally, we examined the possible consequences on somatic parameters and behavior of naturally delivered offspring. We used an experimental model based on overfeeding of outbred mice during intrauterine and early postnatal development to produce the(More)
The aim of our study was to develop a model producing obese mice in early adulthood (4-6 weeks) based on their over-nutrition during fetal and early postnatal development. The fertilized dams of the parental generation were fed the standard diet supplemented with high-energy nutritional product Ensure Plus during gestation and lactation. Delivered weanlings(More)
The aim of the present study was to compare overall patterns of metabolic activity of in vitro cultured preimplantation embryos isolated from normal and fat mice dams by means of non-invasive profiling of spent culture media using Raman spectroscopy. To produce females with two different types of body condition (normal and fat), a previously established(More)
The effect of maternal stress on blastocyst quality, with respect to maternal metabolic status, was investigated in this study. We exposed female mice with different amounts of body fat to restraint stress and examined their blastocyst quality. Blood concentrations of corticosterone, leptin, adiponectin, insulin and glucose were measured in these females.(More)
The aim of our study was to investigate the effect of maternal obesity on the quality and developmental capabilities of in vivo-derived preimplantation embryos. A two-generation dietary model, based on mice overfeeding during intrauterine and early postnatal development, was used to produce four types of female animals: with physiological (7%-8%), slightly(More)
