In vitro culture systems are determinant in embryo development and can impact not only blastocyst rates and viability but also the offspring. One of the main factors influenced by changes in these systems is the embryonic metabolism. At the earliest stages of embryo development, the energetic requirements are mainly maintained by oxidative phosphorylation through high consumption of pyruv…
The effects of the in vitro system on the development of the pre-implantation embryo are determinant for its viability and post-transfer success. Modifications in this system have been suggested, especially in relation to the increase of energy metabolism by the modulation of substrates such as glucose, pyruvate and several amino acids. However, the impact of these supplements may be beyo…
In vitro production of bovine embryos is still considered a low-efficiency biotechnology, once the technique has, on average, lower pregnancy rates when compared to in vivo. Although the in vitro culture system tries to mimic what occurs in vivo, embryos end up being exposed to various stress factors that they would usually do not suffer inside the reproductive tract. In addition to intri…

Modifications of the in vitro embryo production system may be determinant for the adequate development of the pre-implantation embryo. Modifications related to energy metabolism, such as increased or decreased availability of substrates, may have consequences not only in survival but also in molecular control of the embryo. At the beginning of development, pyruvate and to some extent lact…
The ability to develop embryos up to blastocyst stage without any contact with the maternal reproductive tract hypothesized that the oviduct would be minor and inessential at the early stage of. Today, however, it is widely known that the embryo-oviduct interaction, or interaction with oviductal cells' products, can impact the embryo in different ways, especially regarding epigenetic char…
The oviduct is the anatomical region where life begins in most mammal species, as it is the meeting point between sperm and oocytes for fertilization, in addition to providing the appropriate environment for early embryonic development. The reproductive events that occur in the oviduct depend on synchronized signaling processes, which involve communication between the different types of c…
In vitro maturation (MIV) is one of the primordial steps for the success of in vitro production (PIV) of bovine Embrys, since there is the triggering of severe processes that collaborate for the development and the quality of the future embryo. Epigenetic reprogramming is one of the processes carried out in MIV, in which the bovine oocyte goes through an intense regulation of Epigenetic m…
The in vitro culture system of embryos is crucial to determine its ability to reach the blastocyst stage and, in particular, its viability and success after transfer. Changes in this system are often employed and many of them are based in the addition of carbohydrates and amino acids as supplements of culture medium. However, this supplementation is usually in different concentrations tha…

The epigenetic reprogramming that occurs during the earliest stages of the embryonic development has been described as crucial for the initial events of cell specification and differentiation. Recently, the metabolic status of the embryo has gained attention as one of the main factors coordinating epigenetic events. For this present proposal, we start from previous results with the hypoth…
The existence of early embryomaternal communication already in the oviducts has been for too long underestimated. It is observed that the oviducts are cyclically prepared to receive a pregnancy in each estrous cycle, but when the embryo is indeed present, it is now known that a two-way communication is established between the oviductal cells and the embryo. Even though this communication …
During the first cleavages of bovine embryos, the DNA demethylation (active and passive) occurs and will be responsible for the production of totipotent cells, until around 8-16 cells. Then the DNA of these embryos must be methylated again until, at the blastocyst stage, when its blastomeres are classified as pluripotent and differentiated as belonging to the internal cell mass or trophec…

Embryos with high amounts of lipids have their development impaired, with increased embryo death and lower survival after cryopreservation. Additionally, the lipid content is associated with lower pregnancy rates and low success cryopreservation of IVP embryos when compared to embryos produced in vivo. A component which is present in both lipid droplets as the membranes is cholesterol, wh…
