Special Issue Information

Dear Colleagues,

In embryology, we monitor how the oocyte is fertilized and how it divides to create a community of cells that change shape, cleave, move to new destinations, and communicate with each other using a variety of molecular signals. We aim to determine how the embryo constructs itself with the hope of eventually understanding how the body and organs are built and how malformations arise.

Most studies carried out on early embryonic development have focused on inbred mice, but studies using domestic animals have also significantly contributed to the rapid progress seen in this field. It has been emphasized that many aspects of early development in domestic animals are similar to those in human development, and therefore a better knowledge of this process in livestock could also better our understanding of human development. Additionally, research on differences in early embryo development between various species of domestic animals is of particular interest, not only for basic veterinary research but also for veterinary clinicians.

Veterinary medicine contributes important data to the understanding of the generation of male and female germ cells, the fertilization process and the development of stem cells. Additionally, the interactions between embryo(s) and their maternal environment, which are the basis of successful pregnancy (embryo–maternal interactions), are of particular interest for this Special Issue. Contributions focused on all the abovementioned areas (either in the form of original papers or reviews) are welcome in this Special Issue, “The Development of Embryos in Livestock and Embryo-Maternal Interactions”.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Veterinary Sciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs).

Pigs have the highest percentage of embryonic death not associated with specific diseases of all livestock species, at 20–45%. During gestation processes, a series of complex alterations can arise, including embryonic migration and elongation, maternal immunological recognition of pregnancy, and embryonic competition for implantation sites and subsequent nutrition requirements and development. Immune cells and cytokines act as mediators between other molecules in highly complex interactions between various cell types. However, other non-immune cells, such as trophoblast cells, are important in immune pregnancy regulation. Numerous studies have shed light on the crucial roles of several cytokines that regulate the inflammatory processes that characterize the interface between the fetus and the mother throughout normal porcine gestation, but most of these reports are limited to the implantational and peri-implantational periods. Increase in some proinflammatory cytokines have been found in other gestational periods, such as placental remodeling. Porcine immune changes during delivery have not been studied as deeply as in other species. This review details some of the immune system cells actively involved in the fetomaternal interface during porcine gestation, as well as the principal cells, cytokines, and molecules, such as antibodies, that play crucial roles in sow pregnancy, both in early and mid-to-late gestation.
