A novel method for transmission electron microscopy study of cytoplasmic fragments from preimplantation human embryos [PDF]

open access: yes, 2016
Transmission electron microscopy (TEM) is the main tool for exploring the intracellular damage and organelle distribution. The cause of producing embryo cytoplsamic fragmentation is not completely understood.

IGF1-mediated human embryonic stem cell self-renewal recapitulates the embryonic niche

open access: yesNature Communications, 2020
The signals regulating the establishment and maintenance of the pluripotent epiblast in human embryos are unclear. Here, the authors use a bioinformatics approach to identify the role of IGF1 in human embryo development, and from this, propose a culture ...

Fixed versus flexible antagonist protocol in women with predicted high ovarian response except PCOS: a randomized controlled trial

open access: yesBMC Pregnancy and Childbirth, 2021
Background No previous study directly compares the fixed day-5 initiation versus the flexible initiation of GnRH antagonist administration in IVF/ICSI for those patients who are predicted as high ovarian responders without PCOS.

An immunological approach of sperm sexing and different methods for identification of X- and Y-chromosome bearing sperm [PDF]

open access: yesVeterinary World, 2017
Separation of X- and Y-chromosome bearing sperm has been practiced for selection of desired sex of offspring to increase the profit in livestock industries. At present, fluorescence-activated cell sorter is the only successful method for separation of X-

Digital Three-Dimensional Atlas of Quail Development Using High-Resolution MRI [PDF]

open access: yes, 2007
We present an archetypal set of three-dimensional digital atlases of the quail embryo based on microscopic magnetic resonance imaging (µMRI). The atlases are composed of three modules: (1) images of fixed ex ovo quail, ranging in age from embryonic day 5

Endometrial stromal cells of women with recurrent miscarriage fail to discriminate between high- and low-quality human embryos [PDF]

open access: yes, 2012
Background The aetiology of recurrent miscarriage (RM) remains largely unexplained. Women with RM have a shorter time to pregnancy interval than normally fertile women, which may be due to more frequent implantation of non-viable embryos.

Truncated C-terminus of fibrillin-1 induces Marfanoid-progeroid-lipodystrophy (MPL) syndrome in rabbit

open access: yesDisease Models & Mechanisms, 2018
Various clinical differences have been observed between patients with the FBN1 gene mutation and those with the classical Marfan phenotype. Although FBN1 knockout (KO) or dominant-negative mutant mice are widely used as an animal model for Marfan ...
