Cell-based Therapies and Medical Devices for Regenerative Medicine: from Veterinary Medicine to Men

The research group evidences a strong and reference activity aiming the Regenerative Medicine and Tissue Engineering as critical areas of the Biomedicine and Biotechnology in a perspective of One Health. The main research projects are focused in tissue regeneration, associating innovate biomaterials to autologous/ allogenic/ xenogenic stem cells, from extra-fetal sources, like the umbilical cord blood and matrix, the bone marrow, the synovia membrane and dental pulp.

A successful demonstration is followed by the establishment of collaboration with biotechnology and pharmaceutical industries working as partners, for product development, protection of intellectual property, validation in different animal models, in a long time-scale trials and further, the future application in clinics. Excellent examples of specific programs with the Industry are: 1) Regeneration of neuromuscular tissue - an Integrative Approach; 2) Nanostructured hybrid hydrogels and synthetic bone substitutes: multifunctional injectable hydrogels for bone regeneration; 3) Development of molecular and cell-based therapies activities for Veterinary and Human Clinical Applications; 4) Pre-clinical and clinical trials of cell-based therapies and medical devices for Veterinary and Human Clinical Applications.

The multidisciplinary team, including Veterinaries, Engineers, Medical Doctors that through Experimental Surgery have a crucial role in the development of biomaterials/medical devices and cell-based therapies, allows a close share of knowledge between biomaterials design, development of cellular systems, and surgeons’ needs, with an extensive experience in advanced therapy medicinal product (ATMP) development in the bio-industry point of view, with a clear vision of what is required regulatory wise to achieve a translational final production for Animals and Humans.

Recognized scientific achievements include scientific publications, higher education and training and already 3 products in the market (cell-based therapies from dental pulp and Whärton’s jelly, and a synthetic bone substitute) and an international patent - Regenera, in the final stage of proof-of-concept for horses and companion animals.

Welfare, quality and safety of fish

Seafood is one of the food groups whose consumption is most encouraged by current nutritionists, as a result of its recognized benefits to human health. As a food of the future, in addition to sustainability, it is important to improve the methods for evaluating its quality and food safety.

The ongoing research at the Laboratory of Fish Technology of the Department of Aquatic Production of ICBAS focuses mainly on the development of new sensory, chemical and microbiological methods to assess the freshness of fish and identify its origin and authenticity. Measures to assess and improve animal welfare in aquaculture and the management and use of waste from their production are also research areas.

In sensory analysis, new tables under the 'Quality Index Method' have been created, for several aquatic species with relevance in Portugal.

In the area of chemistry, work was carried out for the nutritional and toxicological characterization (16 different elements) of species at the top of the food chain, presumably more problematic.

In microbiology, studies have been made to characterize the fish microflora, as well as the development of new microbiological techniques for characterization and identification of the origin of aquaculture species.

Waste management studies have been focused on the identification of sources, characterization of waste and its use as ingredient in feeds for animals, especially from aquaculture.

The work has also included the characterization of animal welfare in aquaculture fish, especially slaughter methods and improvement of their efficiency.

In the area of certification, a list of international systems for the certification of aquatic products and the main products was made, and technical support has been given to seafood companies in the creation of this type of systems for Portuguese products.

A balanced and healthy environment will support the growth of healthy aquatic beings, which will be adequate food items, providing health to animals and humans, confirming the modern vision of One Health we all want for our future world.

The ecology of antimicrobial resistance

Microbiology has made a decisive contribution to the development of the One Health, particularly when combined with advanced microbial genomic tools. Through them, we can investigate outbreaks (e.g. Salmonella spp., Campylobacter jejuni), monitor variants of pathogenic microorganisms or understand the global circulation of bacteria and resistance genes between the human, animal and environmental biome. In fact, the bacterial species that we are most concerned about in terms of resistance (ESKAPE*) share three characteristics: (i) can colonize more than one animal species, (ii) behave mostly like commensal (e.g., are able to colonize the intestine or skin of humans and animals without causing any disease), and (iii) have a remarkable eco-resistance, being able to survive on inert surfaces, in soil or in water for a long time. Therefore, they are able to “travel” between different hosts, demonstrating that without a holistic view we will not be able to contain them.

Under this perspective, the microLAB Laboratory of the Aquatic Production Department of ICBAS – in collaboration with companies, institutions and other research groups – has been studying:

1. The presence of multi-resistant Enterobacteriaceae in different animal populations (chickens, gulls, birds of prey, wolves, bivalves, sea urchins, rabbits, dogs and cats), in humans (pet owners) and in the environment (stations of wastewater treatment, rivers, beaches, lakes and city fountains);

2. The antibacterial activity of hundreds of chemical compounds isolated in cyanobacteria and marine fungi or modified/generated by chemical synthesis processes, provided by collaborating research groups;

3. The phylogenetic proximity between bacteria isolated from humans and bacteria obtained from trains and buses (Staphylococcus aureus resistant to methicillin-MRSA) or in chickens and dogs (Campylobacter jejuni).

*Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacter spp.
