Stejskalova A, Oliva Jorge N, England F, Almquist Bet al., 2019, Biologically inspired, cell-selective release of aptamer-trapped growth factors by traction forces, Advanced Materials, Vol: 31, ISSN: 0935-9648

Biomaterial scaffolds that are designed to incorporate dynamic, spatiotemporal information have the potential to interface with cells and tissues to direct behavior. Here we describe a bioinspired, programmable nanotechnology-based platform that harnesses cellular traction forces to activate growth factors, eliminating the need for exogenous triggers (e.g. light), spatially diffuse triggers (e.g. enzymes, pH changes) or passive activation (e.g. hydrolysis). We use flexible aptamer technology to create modular, synthetic mimics of the Large Latent Complex that restrains TGF-β1. This flexible nanotechnology-based approach is shown here to work with both platelet-derived growth factor-BB (PDGF-BB) and vascular endothelial growth factor (VEGF-165), integrate with glass coverslips, polyacrylamide gels, and collagen scaffolds, enable activation by various cells (e.g. primary human dermal fibroblasts, HMEC-1 endothelial cells) and unlock fundamentally new capabilities such as selective activation of growth factors by differing cell types (e.g. activation by smooth muscle cells but not fibroblasts) within clinically relevant collagen sponges.

Artzi N, Oliva N, Puron C, Shitreet S, Artzi S, Ramos AB, Groothuis A, Sahagian G, Edelman ERet al., 2011, In vivo and in vitro tracking of erosion in biodegradable materials using non-invasive fluorescence imaging, Nature Materials, Vol: 10, Pages: 704-709, ISSN: 1476-1122

The design of erodible biomaterials relies on the ability to program the in vivo retention time, which necessitates real-time monitoring of erosion. However, in vivo performance cannot always be predicted by traditional determination of in vitro erosion1,2, and standard methods sacrifice samples or animals3, preventing sequential measures of the same specimen. We harnessed non-invasive fluorescence imaging to sequentially follow in vivo material-mass loss to model the degradation of materials hydrolytically (PEG:dextran hydrogel) and enzymatically (collagen). Hydrogel erosion rates in vivo and in vitro correlated, enabling the prediction of in vivo erosion of new material formulations from in vitro data. Collagen in vivo erosion was used to infer physiologic in vitro conditions that mimic erosive in vivo environments. This approach enables rapid in vitro screening of materials, and can be extended to simultaneously determine drug release and material erosion from a drug-eluting scaffold, or cell viability and material fate in tissue-engineering formulations.
