Silk structure and degradation

- The immunogenicity of fibroin and sericin had no essential difference.
- In the process of in vitro and in vivo degradation of silk, the role of the enzyme is not significant, and tissue liquid has no impact on the in vivo degradation of silk.
- The In vivo degradation of silk is not a uniform process, and it is related to cell mobilization.
- The in vivo degradation of silk is related to phagocytotic activity and fibroblasts may be involved in this process to secrete collagen.
- PBS is the optimal choice of degradation solution for studying in vitro degradation properties of biological materials.
