Morphological and morphometric study of early-cleavage mice embryos resulting from in vitro fertilization at different cleavage stages after vitrification
The aim of this study was to examine the possible morphological and morphometric changes resulting from vitrification of embryos at the cleavage stage. In this study, 30 mice early-cleavage embryos at different stages of cleavage, resulting from in vitro fertilization (IVF) techniques, were examined before and after vitrification. Digital images were taken from embryos before and after vitrific...
متن کاملCleavage of Human Embryos: Options and Diversity
In order to estimate the diversity of embryo cleavage relatives to embryo progress (blastocyst formation), time-lapse imaging data of preimplantation human embryo development were used. This retrospective study is focused on the topographic features and time parameters of the cleavages, with particular emphasis on the lengths of cleavage cycles and the genealogy of blastomeres in 2- to 8-cell h...
متن کاملTiming of The First Zygotic Cleavage Affects Post-Vitrification Viability of Murine Embryos Produced In Vivo
Background Timing of the first zygotic cleavage is an accurate predictor of embryo quality. Embryos that cleaved early (EC) have been shown to exhibit higher developmental viability compared to those that cleaved at a later period (LC). However, the viability of EC embryos in comparison to LC embryos after vitrification is unknown. The present study aims to investigate the post-vitrification de...
متن کاملCleavage and Gastrulation in Drosophila Embryos
The cytoskeleton guides early embryogenesis in Drosophila, which is characterized by a series of rapid synchronous syncytial nuclear divisions that occur in the absence of cytokinesis. Following these divisions, individual cells are produced in a process called cellularization, and these cells are rearranged during the process of gastrulation to produce an embryo composed of three primordial ti...
متن کاملO-23: Transfer of Blastocysts Derived from Frozen Thawed Cleavage Stage Embryos Improved Ongoing Pregnancy
Background: The aim of our study was to compare the resulting from transfer of embryos that cryopereserved in cleavage stage after thawing and transfer of embryos after thawing and culture in sequentional media until blastocyst formation. Materials and Methods: In this prospective clinical study, we have evaluated 128 cycles in women undergone in vitro fertilization (IVF) or intracytoplasmic sp...
