Modeling human trophoblast, the placental epithelium at the maternal fetal interface. [PDF]
, 2020 Appropriate human trophoblast lineage specification and differentiation is crucial for the establishment of normal placentation and maintenance of pregnancy. However, due to the lack of proper modeling systems, the molecular mechanisms of these processes

Assessment of aneuploidy concordance between clinical trophectoderm biopsy and blastocyst
Human Reproduction, 2018 STUDY QUESTION Is a clinical trophectoderm (TE) biopsy a suitable predictor of chromosomal aneuploidy in blastocysts? SUMMARY ANSWER In the analyzed group of blastocysts, a clinical TE biopsy was an excellent representative of blastocyst karyotype in ...

Transient Sperm Starvation Improves the Outcome of Assisted Reproductive Technologies
Frontiers in Cell and Developmental Biology, 2019 To become fertile, mammalian sperm must undergo a series of biochemical and physiological changes known as capacitation. These changes involve crosstalk between metabolic and signaling pathways and can be recapitulated in vitro.

Agouti C57BL/6N embryonic stem cells for mouse genetic resources. [PDF]
, 2009 We report the characterization of a highly germline competent C57BL/6N mouse embryonic stem cell line, JM8. To simplify breeding schemes, the dominant agouti coat color gene was restored in JM8 cells by targeted repair of the C57BL/6 nonagouti mutation ...

Future Perspectives of POSEIDON Stratification for Clinical Practice and Research
Frontiers in Endocrinology, 2019 A total of 50% of patients undergoing IVF treatment has previously been estimated to fulfill the POSEIDON classification criteria; importantly, although the reproductive prognosis differs between patients, POSEIDON patients share the same characteristic ...

Regulated mitochondrial DNA replication during oocyte maturation is essential for successful porcine embryonic development. [PDF]
, 2006 Cellular ATP is mainly generated through mitochondrial oxidative phosphorylation, which is dependent on mitochondrial DNA (mtDNA). We have previously demonstrated the importance of oocyte mtDNA for porcine and human fertilization.

Genetic Normalization of Differentiating Aneuploid Human Embryos [PDF]
, 2011 Early embryogenesis involves a series of dynamic processes, many of which are currently not well described or understood. Aneuploidy and aneuploid mosaicism, a mixture of aneuploid and euploid cells within one embryo, in early embryonic development are ...
