introduction: the origin of neonatal oocyte development is unknown. however, estrogen plays an essential role during development of the female reproductive system. anastrozole is used as both ovulation stimulating and an anticancer drug. the aim of this study was to evaluate the impact of anastrozole on follicular development and differentiation in mice. materials and methods: in the present st...

organotypic spinal cord slices from neonatal mammals could be a powerful model for evaluation of cell survival but also cell death mechanisms. the aim of this study was to establish an in vitro model for investigating cell survival and mechanism involved in cell death in neonatal spinal cord slices. the spinal cord was sliced and incubated into culture medium. the mtt assay was carried out to a...

background: amniotic membrane derived stem cells (amscs) have considerable advantages to use in regenerative medicine and their anti- inflammatory effects, growth factor secretion and differentiation potential make them suitable candidates for stem cell therapy of nervous system. the developing and neonatal brain contains a spectrum of growth factors to direct development of endogenous and dono...

introduction: lactate dehydrogenase is one of the cardiac enzyme markers, studied in vivo. in the present study, activity and kinetic properties of enzyme extracted from cardiomycytes derived from mouse embyronic stem cell in vitro were compared with enzyme extracted mouse neonatal from cardiomyocytes in vivo. material and methods: mouse embryonic stem cells were cultured and differentiated and...

BACKGROUND Current knowledge indicates that oxidative damage and the following inflammation is pivotal pathway for myocardial cell death. In recent decades, hydrogen sulfide (H2S) has been identified as a novel endogenous vasodilator and neuromodulator due to its antioxidation capacity. However, whether H2S pretreatment in neonatal mouse cardiomyocytes is a protection effect against oxidative s...

introduction: this study was performed to investigate the effect of vitrification procedure using ethyleneglycol as cryoprotectant on the follicular morphology of neonatal ovarian tissue of mouse after thawing andautotransplantation. material and methods: ovaries from 3 weeks neonate nmri mice were excised then vitrified in asolution of dmem medium containing ficol 70, sucrose, acetanied and et...

The mouse represents the model of choice to study the biological function of mammalian genes through mutation of its genome. However, the biggest challenge of mouse geneticists remains the phenotypic analysis of mouse mutants. A survey of mouse mutant databases reveals a surprisingly high number of gene mutations leading to neonatal death. These genetically modified mouse mutants have been inst...

Neonatal studies in different mouse strains reveal that early life colonization affects the development of adaptive immunity in mice. The nonobese diabetic (NOD) mouse spontaneously develops autoimmune diabetes, but neonatal studies of NOD mice are lacking. We hypothesized that NOD mice deviate from another much used mouse strain, C57BL/6, with respect to postnatal microbiota and/or hematopoies...
