Abstract

The surgically induced angiogenesis by means of arteriovenous (AV) loops represents a powerful method to significantly enhance vascularization of biomaterials. Regarding tissue engineering applications, spider silk is a promising biomaterial with a good biocompatibility and slow biodegradation. This study aims at investigating vascularization as well as de novo tissue formation of fibrous matrices made of electro-spun (ES) or wet-spun (WS) engineered ADF4(C16) spider silks in the rat AV loop model. Either ES or WS spider silk fibrous matrices were filled into Teflon chambers. Intrinsic vascularization was induced by means of an AV loop. After 4 weeks of vascularization, de novo tissue formation and biocompatibility were analyzed. Regardless of their significantly differing fiber diameters, both ES and WS eADF4(C16) fiber matrices displayed a good biocompatibility and initiated de novo tissue formation as well as vessel formation. Both matrices demonstrated partial vascularization originating from the AV loop, with more vessels in spider silk matrices with lower fiber diameters. We were able to demonstrate intrinsic vascularization of spider silk fibrous matrices by means of the AV loop. Moreover, our study indicates that the adjustment of the fiber diameter of engineered spider silks enables new possibilities to optimize vascularization.
