This study aimed to examine thematic shifts in biomaterials research related to wound healing and to evaluate the emerging role of marine-derived materials. A total of 4,316 Web of Science publications (1990–2024) were analyzed using Latent Dirichlet Allocation. Topic modeling revealed a transition from pre-2008 focus on scaffold structure and in vitro cellular interactions toward post-2008 themes emphasizing in vivo evaluation, functional hydrogels, antimicrobial systems, and regenerative tissue engineering. Marine-derived collagens, particularly fish collagen, have gained increasing attention due to their biocompatibility, biodegradability, and ethical advantages; however, they remain underrepresented compared with mammalian sources. For transparency, the token ‘marine’ appeared in 34 abstracts overall (0.79% of the corpus). When stratified by period, it appeared in 0/297 abstracts before 2008 (0.0%) and in 34/4019 abstracts between 2008–2024 (0.85%), indicating an increase in explicit mention after 2008, while remaining a low-frequency signal. Therefore, ‘marine’ was interpreted as a secondary, qualitative signal rather than a dominant topic-forming term. Standardized extraction methods, interspecies comparative studies, and long-term in vivo safety assessments are needed to support their translational use. Strengthening interdisciplinary collaborations will accelerate their integration into clinical and veterinary practice.
