Funding Sources - We are grateful for the generous support of the following  funding agencies for supporting our research.

The glioma cell brain slice invasion model. Human U118 glioma cells stably expressing green fluorescent protein (GFP) were delivered with a micropipette onto a mouse brain slice. Photographs were taken at the indicated times using an inverted fluorescent microscope. The white line denotes the boundary between the cell delivery site and the adjacent brain tissue. Magnification is 20X.

Nanoparticle formulations designed to minimize non-specific binding enable improved penetration and dispersion within tissues.  Here, nanoparticles with very dense PEG coatings (green) are shown penetrating within brain tissue in vivo.  Uncoated particles (red) with hydrophobic and negative charge surface regions display limited dispersion within brain tissue.  Minimizing the non-specific bindings of therapeutic formulations is a foundational principle of our work (Nance and Woodworth et al., Science Translational Medicine, 2012; Schneider et al., Biomaterials, 2015; Wadajkar et al., Journal of Controlled Release, 2017).
