Comparison of Different Methods for Spongin-like Collagen Extraction from Marine Sponges (Chondrilla caribensis and Aplysina fulva): Physicochemical Properties and In Vitro Biological Analysis [PDF]

Membranes, 2021
This study aimed to compare different protocols (Protocol 1: P1; Protocol 2: P2; Protocol 3: P3; Protocol 4: P4) for the extraction of spongin-like collagen (SC) from marine sponges. The SEM micrographs demonstrated a fibrillar structure for the extracts

Bioglass-Reinforced Spongin-Like Collagen Scaffolds for Osteoporotic Bone Tissue Engineering [PDF]

ACS Omega
Osteoporotic fractures pose a significant clinical challenge due to impaired bone regeneration. In this study, composite scaffolds based on Bioglass 45S5 (BG) and marine-derived spongin-like collagen (SPG) were developed and analyzed. Characterization techniques included scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy ...

Adsorption of C.I. Natural Red 4 onto Spongin Skeleton of Marine Demosponge [PDF]

Materials, 2014
C.I. Natural Red 4 dye, also known as carmine or cochineal, was adsorbed onto the surface of spongin-based fibrous skeleton of Hippospongia communis marine demosponge for the first time. The influence of the initial concentration of dye, the contact time,

Different Species of Marine Sponges Diverge in Osteogenic Potential When Therapeutically Applied as Natural Scaffolds for Bone Regeneration in Rats [PDF]

Journal of Functional Biomaterials, 2023
A highly porous structure, and an inorganic (biosilica) and collagen-like organic content (spongin) makes marine sponges potential candidates to be used as natural scaffolds in bone tissue engineering.
