Where technology & law meet: Open Access research on data security & its regulation ...

Strathprints makes available Open Access scholarly outputs exploring both the technical aspects of computer security, but also the regulation of existing or emerging technologies. A research specialism of the Department of Computer & Information Sciences (CIS) is computer security. Researchers explore issues surrounding web intrusion detection techniques, malware characteristics, textual steganography and trusted systems. Digital forensics and cyber crime are also a focus.

Meanwhile, the School of Law and its Centre for Internet Law & Policy undertake studies on Internet governance. An important component of this work is consideration of privacy and data protection questions and the increasing focus on cybercrime and 'cyberterrorism'.

Abstract

The therapeutic success of haematopoetic stem and progenitor cell (HSPC) transplantation is critically dependent on HSPC engraftment in the bone marrow. Gradients of stromal cell-derived factor 1 (SDF1) direct HSPC homing, both in vitro and in vivo. Potentially, regulating the delivery levels of exogenous SDF1 applied to the bone marrow could augment HSPC engraftment. Thus, the aim of the present study was to revise the ability of biocompatible hydrogels to direct HSPC migration in vitro. The delivery system of choice is based on heparin cross-linked with collagen1. We confirm that hydrogel is capable of trapping and releasing SDF1 and using it to generate a protein gradient in transendothelial migration experiments. The use of SDF1-functionalised hydrogel to produce a chemokine gradient revealed, sustained and increased HSPC migration when compared to diffusible SDF1 controls. In conclusion, regulating SDF1 gradients with heparin-containing hydrogels may offer valuable options to direct site-specific migration of HSPC.
