Modelling oxygen diffusion and cell growth in a porous, vascularising scaffold for soft tissue engineering applications

Soft tissue engineering presents significant challenges compared to other tissue engineering disciplines such as bone, cartilage or skin engineering. The very high cell density in most soft tissues, often combined with large implant dimensions, means that the supply of oxygen is a critical factor in the success or failure of a soft tissue scaffold. A model is presented for oxygen diffusion in a 15-60 mm diameter dome-shaped scaffold fed by a blood vessel loop at its base. This model incorporates simple models for vascular growth, cell migration and the effect of cell density on the effective oxygen diffusivity. The model shows that the dynamic, homogeneous cell seeding method often employed in small-scale applications is not applicable in the case of larger scale scaffolds such as these. Instead, we propose the implantation of a small biopsy of tissue close to a blood supply within the scaffold as a technique more likely to be successful.

Structure and ultrastructure of the silk glands and spinneret of Helicoverpa armigera (Hubner) (Lepidoptera : Noctuidae)

This study provides comprehensive documentation of silk production in the pest moth Helicoverpa armigera from gland secretion to extrusion of silk thread. The structure of the silk glands, accessory structures and extrusion apparatus are reported. The general schema of the paired silk glands follows that found for Lepidoptera. Morphology of the duct, silk press, muscle attachments and spigot are presented as a three-dimensional reconstruction and the cuticular crescent-shaped profile of the silk press is demonstrated in both open and closed forms with attendant muscle blocks, allowing advances in our knowledge of how the silk press functions to regulate the extrusion of silk. Growth of the spigot across instars is documented showing a distinctive developmental pattern for this extrusion device. Its shape and structure are related to use and load-bearing activity.

The absolute structural requirement for a proline in the P3 '-position of Bowman-Birk protease inhibitors is surmounted in the minimized SFTI-1 scaffold

SFTI-1 is a small cyclic peptide from sunflower seeds that is one of the most potent trypsin inhibitors of any naturally occurring peptide and is related to the Bowman-Birk family of inhibitors (BBIs). BBIs are involved in the defense mechanisms of plants and also have potential as cancer chemopreventive agents. At only 14 amino acids in size, SFTI-1 is thought to be a highly optimized scaffold of the BBI active site region, and thus it is of interest to examine its important structural and functional features. In this study, a suite of 12 alanine mutants of SFTI-1 has been synthesized, and their structures and activities have been determined. SFTI-1 incorporates a binding loop that is clasped together with a disulfide bond and a secondary peptide loop making up the circular backbone. We show here that the secondary loop stabilizes the binding loop to the consequences of sequence variations. In particular, full-length BBIs have a conserved cis-proline that has been shown previously to be required for well defined structure and potent activity, but we show here that the SFTI-1 scaffold can accommodate mutation of this residue and still have a well defined native-like conformation and nanomolar activity in inhibiting trypsin. Among the Ala mutants, the most significant structural perturbation occurred when Asp(14) was mutated, and it appears that this residue is important in stabilizing the trans peptide bond preceding Pro(13) and is thus a key residue in maintaining the highly constrained structure of SFTI-1. This aspartic acid residue is thought to be involved in the cyclization mechanism associated with excision of SFTI-1 from its 58-amino acid precursor. Overall, this mutational analysis of SFTI-1 clearly defines the optimized nature of the SFTI-1 scaffold and demonstrates the importance of the secondary loop in maintaining the active conformation of the binding loop.
