Special Issue Information

Dear Colleagues,

In recent years, there has been rapidly growing interest in biomaterials for various in vitro and in vivo biomedical research and applications. Among these, collagen-based biomaterials have gained prominence, particularly in fields such as tissue engineering. However, the use of mammalian collagen presents challenges, including religious constraints, allergic or autoimmune reactions, and the risk of disease transmission from animals.

In recent decades, marine collagen (MC) has emerged as a promising alternative biomaterial for pharmacological and biomedical applications. Marine organisms provide a rich source of collagen, and MC offers several advantages over mammalian collagen, including water solubility, easy extractability, low immunogenicity, safety, biocompatibility, biodegradability, antimicrobial activity, functionality, and lower production costs. Due to its unique characteristics and physicobiochemical properties, MC holds tremendous potential as a scaffold biomaterial in tissue engineering, regenerative medicine, drug delivery systems, and therapeutic applications.

This Special Issue, "Marine Collagen: From Biological Insights to Biomedical Breakthroughs," invites submissions that explore the latest developments, advancements, trends, challenges, and future perspectives in this exciting field. We welcome contributions from various areas of multidisciplinary research, ranging from fundamental studies (including extraction, purification, characterization, fabrication, and experimentation) to biotechnological, pharmacological, biomedical, and therapeutic applications of MC. Additionally, comprehensive review papers are also encouraged for submission.

We look forward to receiving valuable contributions to this Special Issue.

Research increasingly highlights jellyfish as a sustainable alternative to other animal species, particularly for its collagen, which has versatile applications in blue biotechnology. This review explores the properties of jellyfish-derived collagen, extraction techniques, and its diverse industrial applications based on the current scientific literature. With a particular focus on research in the Mediterranean Sea, we underscore the role of the order Rhizostomeae as jellyfish species with high collagen content and provide an overview of the main sources for jellyfish harvesting, including active fishing, by-catch, and aquaculture. In the Mediterranean basin, the blooming species Rhizostoma pulmo, Cotylorhiza tuberculata, and Rhopilema nomadica represent a valuable opportunity to harness their nutraceutical benefits, as well as their potential for the development of biomaterials in tissue engineering and regenerative medicine. Although jellyfish fishing is not yet well-established in the region, ongoing collaborative projects with fishermen’s guilds are focused on promoting circular and blue economy strategies to valorize jellyfish as an innovative resource. Additionally, jellyfish aquaculture emerges as a promising alternative for ensuring a sustainable supply, with the Rhizostomeae Cassiopea spp. demonstrating significant potential for biotechnological applications.

Collagen is a structural protein found in the connective tissues of terrestrial and marine animals. Its diverse functional attributes span its applications in several industries, including food, supplements, cosmetics, and pharmaceuticals. Typically derived from mammalian sources, collagen and its derivatives, including gelatin and collagen peptides, are essential for the food and supplement industries. Recently, marine collagen has emerged as a viable mammalian collagen alternative due to its unique functionality and sustainability. Marine vertebrates and invertebrates are reliable sources of marine collagen. Some marine organisms are promising sustainable sources of collagen for nutritional applications. Recent research highlights significant advances in marine collagen extraction, processing, and novel applications. Hence, recent interest has propelled research in identifying novel collagen sources and advancing technologies to produce marine collagen-based products. Considering the recent scientific interest in marine collagen, this review provides an overview of recent progress in marine collagen production, including novel sources, innovative processing technologies, nutritional and functional properties, safety and quality control, current challenges, and future research directions. The review highlights certain challenges, including unpleasant odor, flavor, color, insufficient supply, and inconsistent quality of marine collagen. Future research should focus on increasing the collagen extraction yield, improving the smell and flavor, and developing novel delivery systems to increase bioavailability and functionality.
