Co-culture systems have been designed to overcome the embryonic developmental arrest
observed in vitro in conventional culture media. Oviduct and uterine epithelial cells can …

In the present study, the effects of glucose and/or glycine on the in vitro development of Day
5 (Day 0= IVF) porcine blastocysts were determined. The addition of 2.5–10 mM glucose to …

In the first of two experiments, utilization of [1-14C] pyruvate by 8-cell and blastocyst-stage
embryos derived in vivo was examined during a 3-h incubation in HEPES-buffered synthetic …

Alcohol is a known teratogen that causes a broad variety of developmental anomalies,
including fetal growth retardation, craniofacial anomalies, and neurological disorders. The …

Until now, full-term development of mouse embryos reconstructed from somatic nuclei has
been convincingly achieved only when a piezoimpact pipette drive unit is used for the …

One‐cell mouse embryos that block at the 2‐cell stage can progress to the morula stage in
CZB medium, but fail to cavitate and then swell and lyse. A 1‐min exposure to 27 mM …

Embryotrophic factors from human oviductal cells were partially purified by liquid
chromatographic methods. The conditioned medium from human oviductal cell culture was …

Regarding bull fertility, establishing an association between in vitro findings and field fertility
requires a multi-parametric approach that measures the integrity of various structures and …

In mouse blastocysts six facilitative glucose transporter isoforms (GLUT) 1–4, 8 and 9 are
expressed. We have used the mouse embryonic stem (ES) cell line D3 and spontaneously …

The present study was undertaken to examine the effects of various transition metal ion
chelators, both polyaminocarboxylates (including nitrilotriacetate (NTA) …
