Special Issue Information

Dear Colleagues,

In 1921, two Canadians—Dr. F. Banting and his student C.H. Best—discovered the hormone insulin from canine pancreatic extracts. Furthermore, they showed that high blood glucose levels returned to within the normal range upon the injection of insulin. Almost 100 years later, animals—dogs in particular—have been evolved from experimental or working animals into intimate family members living in close proximity to their owners. This has resulted in high medical care systems for these animals, especially in the Western world. Moreover, production animals are now housed at far larger farms and at higher densities than ever before. This presents an enormous risk to these animals once a microbiological outbreaks occurs. The realization that some of these outbreaks (e.g., Q-fever, SARS) can directly affect the people working with and/or living adjacent to these animals led to the One Health concept. Etiologies and disease progressions are highly similar between humans and animals, and diseases affect humans, animals, and the environment vice versa.

The One Health concept was followed by the One Medicine concept, focusing on the similarities in etiology, molecular biology, disease progression, and treatment modalities for humans and animals. This meant that the molecular and cell-biological innovations used in the laboratory setting in experimental animals (C. elegans, zebrafish, and rodent models) to benefit human medicine are crucial and may be applicable to progress veterinary science as well. It is anticipated that these technical innovations will lead to breakthroughs in modern biomedicine. In order to appreciate these innovations and to provide veterinarians and translational biomedical researchers with the potential of these technologies to advance their field of interest, this Special Issue is devoted to “Molecular and Cell-Biological Innovations to Advance Veterinary Animal Research”. The authors are invited to describe the innovations and make clear to novices and experienced veterinarian researchers how this can be implemented in clinical practice in the near future.

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). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Severe and chronic low back pain is often associated with intervertebral disc (IVD) degeneration. While imposing a considerable socio-economic burden worldwide, IVD degeneration is also severely impacting on the quality of life of affected individuals. Cell-based regenerative medicine approaches have moved into clinical trials, yet IVD cell identities in the mature disc remain to be fully elucidated and tissue heterogeneity exists, requiring a better characterization of IVD cells. The bovine coccygeal IVD is an accepted research model to study IVD mechano-biology and disc homeostasis. Recently, we identified novel IVD biomarkers in the outer annulus fibrosus (AF) and nucleus pulposus (NP) of the mature bovine coccygeal IVD through RNA in situ hybridization (AP-RISH) and z-proportion test. Here we follow up on Lam1, Thy1, Gli1, Gli3, Noto, Ptprc, Scx, Sox2 and Zscan10 with fluorescent RNA in situ hybridization (FL-RISH) and confocal microscopy. This permits sub-cellular transcript localization and the addition of quantitative single-cell derived values of mRNA expression levels to our previous analysis. Lastly, we used a Gaussian mixture modeling approach for the exploratory analysis of IVD cells. This work complements our earlier cell population proportion-based study, confirms the previously proposed biomarkers and indicates even further heterogeneity of cells in the outer AF and NP of a mature IVD.
