Therapeutic potency of marine collagen/pectin scaffolds - Fabrication, Characterization and Evaluation
Abstract
Skin is an important vital organ that must be given proper care and protection from external damage and harmful microbes. If injured, it must be treated with an ideal wound dressing material with potent hemostatic and non-toxic properties. In the present study, fish collagen (FC) was extracted from the fins and tails of Black pomfret (Parastromateus niger). The isolated fish collagen was homogenized with pectin (P) and freeze dried to obtain fish collagen/pectin (FC/P) scaffolds. Scanning electron microscopic analysis showed the porous nature of scaffolds with intermittent holes. UV-Visible and Fourier infrared spectroscopic analyses demonstrated the physicochemical properties of FC/P scaffolds. Hemolytic assay performed using human blood demonstrated the percentage of hemolysis as 0.5 %. In vitro blood clotting assay carried out to determine the hemostatic behaviour displayed the formation of blood clot within 60 seconds in the presence of FC/P scaffolds. 95 % of cells were viable with the highest concentration of FC/P scaffold used for MTT (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide) assay. Scratch wound assay demonstrated complete closure of wound in FC/P scaffold treated cells after 48 hours of treatment. Chick embryo chorioallantoic membrane (CAM) assay showed the development of new blood vessels within 6 hours of incubation with the FC/P scaffolds, thereby proving their angiogenic potency. These results indicate the potential use of FC/P scaffolds as…
