Inflammatory Bowel Disease (IBD) and other non-communicable diseases (NCDs) are responsible for 73.4% (4.1 million people) of annual deaths on the planet. NCDs involving a global burden of economic looses (2011 to 2030) estimated at 47 trillion dollars (5% of gross global product) and so recognized as one of the current biggest global problems. These diseases share, in their etiology and …
Reproductive processes involve complex and finely orchestrated events that allow for the maintenance and propagation of species. Currently, scientific and technological advances allow research to be conducted globally, which may represent a revolution in the understanding of the mechanisms involved in these processes. In addition to elucidating the key events of these processes, there may…

In vitro maturation (IVM) restricts the use of hormones in vivo preventing excessive spending and handling of the animal, and the harmful iatrogenic effects of ovarian overstimulation. However, the IVM systems are not comparably efficient to physiological events that occur in vivo, mainly concerning the synchronization between the nuclear and cytoplasmic maturation of the oocyte. Removed …

Embryo quality plays an important role in selecting the embryo with the greatest potential for implantation and, consequently, for establishing pregnancy. In order to select the best embryos, embryologists have classification systems based on morphological aspects and visual analysis. However, the methodology used to categorize different degrees of quality is prone to variability and subj…
In cattle, the in vitro embryo production (IVEP) represents a crucial biotechnology for the reproduction and genetic improvement of herds, given the global economic importance of livestock. However, despite the growing interest and investment in this field, IVEP still faces significant challenges, such as the low production rate and the quality of embryos, which are still distinct from th…
In the bovine species, in vitro embryo production (IVP) is a biotechnology in growing demand in recent years, with constant search for the development of technical innovations or inputs. The ultimate goal is to improve the quality of the embryo (blastocyst) and, consequently, its ability to tolerate cryopreservation and sustain full term pregnancy. However, one of the inherent problems of…
Within the biotechnology of assisted animal reproduction, in vitro production of bovine embryos is a national highlight. However, the technique induces iatrogenic changes in the embryos produced. Markedly, this is reflected in the cryotolerance of in vitro produced (IVP) embryos and in their altered lipid composition in the plasma membrane and cytoplasm. Among the most recent approaches t…
The bovine embryonic development, both in vivo derived and in vitro produced, involves basic aspects of cell differentiation. Throughout embryonic development, the cells that compose the inner cell mass (ICM) differentiate into two new cell lineages: epiblast (origin of germ-layers) and hypoblast (origin of extraembryonic tissues). The fibroblast growth factor (FGF) acts in differentiatio…

Early embryonic mortality, caused by failures in maternal-fetal recognition in the first three weeks after fertilization represents a major cause of reproductive inefficiency in the cattle industry. During this pre-implantation period, the conceptus (embryo and its associated extra-embryonic membranes) present in the uterine lumen must secrete molecules, such as interferon-tau (IFNT), tha…
After the emergence of induced cell reprogramming, performed through the addition of "Yamanaka" transcription factors (Oct4, Sox2, Klf4 and cMyc) to somatic cells, the amount of researches regarding the generation and maintenance of pluripotency has increased greatly. Still, further investigations on the pluripotent state of these cells are still demanding, since different protocols, char…
In vitro maturation (IVM) does not use superstimulatory hormones in vivo, thereby preventing, overspending and animal handling, in addition to the harmful iatrogenic effects of ovarian overstimulation. However, the efficiency of IVM systems do not meet full expectations due to the inability to simulate the physiological events that occur in vivo (i.e. synchronization between nuclear and c…
