Introduction
The activation of wound healing in crab shells has been a subject of interest due to the unique properties of various compounds derived from these shells. Research has focused on the use of chitosan, hydroxyapatite, collagenase, and other bioactive molecules extracted from crab shells to enhance wound healing and tissue regeneration.
Key Insights
-
Chitosan and Hydroxyapatite for Tissue Regeneration:
- The combination of chitosan gel and hydroxyapatite from crab shells significantly enhances periodontal tissue regeneration by reducing proinflammatory cytokines (IL-1) and increasing bone morphogenetic protein-2 (BMP-2) expression.
- Chitosan extracted from freshwater crab shells accelerates wound healing by shortening the inflammatory phase and promoting faster tissue regeneration.
-
Chitin and Chitosan Membranes for Wound Healing:
- Chitin membranes from soft-shell crab carapaces support cell attachment, proliferation, and migration, improving epidermis surface homogeneity and accelerating epidermis-dermis re-attachment.
- Chitosan membranes show excellent tensile strength and ultimate strain, making them superior to common wound healing membranes from cellulose and collagen.
-
Collagenase for Wound Debridement:
- Collagenase from the Kamchatka crab is highly effective for debridement of infected wounds, enhancing the healing process when applied with gauze or gelevin .
-
Hydroxyapatite for Bone Repair:
- Hydroxyapatite derived from crab shells increases the expression of bone sialoprotein (BSP) and dentine matrix protein-1 (DMP1), promoting bone regeneration in dental socket preservation.
- Nano composite porous 3D scaffolds made from crab shells accelerate bone healing in experimentally induced bone defects in dogs.
-
Phenoloxidase Activity for Exoskeleton Wound Healing:
- Chitin-binding antimicrobial peptides from horseshoe crabs convert hemocyanin to phenoloxidase, which may function as a trigger for exoskeleton wound healing.
Conclusion
Research indicates that compounds derived from crab shells, such as chitosan, hydroxyapatite, and collagenase, significantly enhance wound healing and tissue regeneration. Chitosan and hydroxyapatite are particularly effective in reducing inflammation and promoting bone and tissue regeneration. Chitin membranes support cell proliferation and wound closure, while collagenase is effective for wound debridement. Additionally, hydroxyapatite scaffolds from crab shells show promise in bone repair, and phenoloxidase activity triggered by antimicrobial peptides aids in exoskeleton wound healing. These findings highlight the potential of crab shell-derived materials in medical applications for wound healing and tissue regeneration.
