We now know that cancer is many different diseases, with great variation even within a
single histological subtype. With the current emphasis on developing personalized …

Contents Despite major efforts directed at improving the yield of blastocysts from immature
oocytes in vitro, the quality of such blastocysts continually lags behind that of blastocysts …

We have previously shown that, while the intrinsic quality of the oocyte is the main factor
affecting blastocyst yield during bovine embryo development in vitro, the main factor …

The long-term developmental and behavioral consequences of mammalian embryo culture
are unknown. By altering the culture medium with the addition of FCS, we wanted to …

The birth of 'Dolly', the first mammal cloned from an adult donor cell, has sparked a flurry of
research activities to improve cloning technology and to understand the underlying …

Recent data have demonstrated that fast‐cleaving embryos produced in vitro are more likely
to develop to blastocyst stage, and that the postfertilization culture system used impacts …

The objective was to evaluate the structural and functional quality of bull sperm after sexing
by flow cytometry. Frozen non-sexed (NS), sexed for X (SX) and sexed for Y (SY) sperm from …

Negative energy balance (NEB) during early lactation in dairy cows leads to an altered
metabolic state that has major effects on the production of IGF family members. Low IGF-I …

The ratio of male/female embryos may be modified by environmental factors such as
maternal diet in vivo and the composition of embryo culture media in vitro. We have used …

Procedures for in vitro embryo production in cattle have not been optimized. In the current
experiment, we utilized a 3× 3 factorial design to test whether the proportion of embryos …
