  • Title: Non-bioengineered silk fibroin protein 3D scaffolds for potential biotechnological and tissue engineering applications.
    Author: Mandal BB, Kundu SC.
    Journal: Macromol Biosci; 2008 Sep 09; 8(9):807-18. PubMed ID: 18702171.
    Abstract:
    This paper describes a new source for fabricating high-strength, non-bioengineered silk gland fibroin 3D scaffolds from Indian tropical tasar silkworm, Antheraea mylitta using SDS for dissolution. The scaffolds were fabricated by freeze drying at different prefreezing temperatures for pore size and porosity optimization. Superior mechanical properties with compressive strength in the range of 972 kPa were observed. The matrices were degraded by proteases within 28 d of incubation. Biocompatibility was assessed by feline fibroblast culture in vitro and confocal microscopy further confirmed adherence, spreading, and proliferation of primary dermal fibroblasts. Results indicate nonmulberry 3D silk gland fibroin protein as an inexpensive, high-strength, slow biodegradable, biocompatible, and alternative natural biomaterial. [Figure: see text].
