Special Issue Information

Dear Colleagues,

Collagen is the main fibrous structural protein in the extracellular matrix and connective tissue of animals. It is a primary building block of bones, tendons, skin, hair, nails, cartilage, and all joints in the body. It is also considered a "glue” that holds the body together. The production of collagen begins to slow down and cell structures start losing their strength as we get older. Supplementing with collagen is a vital way to help our body revive and stay youthful. Recently, collagen-based biomedical materials have developed an important and clinically effective materials that have gained wide acceptance. However, collagen extraction from land animal source is complex, time consuming and expensive. Hence, marine sources have started to be researched and found to be the most convenient and safest source for obtaining collagen. Another reason for favouring this source is due to the concern over adverse inflammatory and immunologic response and prevalence of various diseases among land animals which causes health complications.

Marine source has also got plenty advantages over the land animal sources such as: (1) High content of collagen; (2) environment friendly; (3) presence of biological contaminants and toxins almost negligible; (4) low inflammatory response; (5) greater absorption due to low molecular weight; (6) less significant religious and ethical constrains; (7) minor regulatory and quality control problems; (8) metabolically compatible, and much more. This source includes the use of marine invertebrates and vertebrates, such as sponges, coralline red algae, sea urchin, octopus, squid, jellyfish, cuttlefish, star fish, sea anemone, and prawn. Therefore, a huge source of marine collagen is expected to make a great contribution to marine biotechnology products and medical applications.

As a Guest Editor of this Special Issue of Marine Drugs, I invite you to submit recent advances in all the aspects of marine collagen, including original work or reviews and new innovations on the biological sources and their promising applications in medical and related fields.

Collagen is a natural and abundant polymer that serves multiple functions in both invertebrates and vertebrates. As collagen is the natural scaffolding for cells, collagen-based hydrogels are regarded as ideal materials for tissue engineering applications since they can mimic the natural cellular microenvironment. Chondrosia reniformis is a marine demosponge particularly rich in collagen, characterized by the presence of labile interfibrillar crosslinks similarly to those described in the mutable collagenous tissues (MCTs) of echinoderms. As a result single fibrils can be isolated using calcium-chelating and disulphide-reducing chemicals. In the present work we firstly describe a new extraction method that directly produces a highly hydrated hydrogel with interesting self-healing properties. The materials obtained were then biochemically and rheologically characterized. Our investigation has shown that the developed extraction procedure is able to extract collagen as well as other proteins and Glycosaminoglycans (GAG)-like molecules that give the collagenous hydrogel interesting and new rheological properties when compared to other described collagenous materials. The present work motivates further in-depth investigations towards the development of a new class of injectable collagenous hydrogels with tailored specifications. Full article

In search of alternative and safer sources of collagen for biomedical applications, the marine demosponges Axinella cannabina and Suberites carnosus, collected from the Aegean and the Ionian Seas, respectively, were comparatively studied for their insoluble collagen, intercellular collagen, and spongin-like collagen content. The isolated collagenous materials were morphologically, physicochemically, and biophysically characterized. Using scanning electron microscopy and transmission electron microscopy the fibrous morphology of the isolated collagens was confirmed, whereas the amino acid analysis, in conjunction with infrared spectroscopy studies, verified the characteristic for the collagen amino acid profile and its secondary structure. Furthermore, the isoelectric point and thermal behavior were determined by titration and differential scanning calorimetry, in combination with circular dichroism spectroscopic studies, respectively.
