Macroporous Hydrogels for Stable Sequestration and Sustained Release of Vascular Endothelial Growth Factor and Basic Fibroblast Growth Factor Using Nucleic Acid Aptamers.

ABSTRACT: Macroporous hydrogels have been widely studied for biological and biomedical applications such as drug delivery and tissue engineering. However, these hydrogels cannot stably sequester molecules of interest due to their high permeability. The purpose of this work was to study the feasibility of using two aptamers to sequester two protein drugs, quantify the apparent diffusivity of protein drugs in aptamer-functionalized macroporous hydrogels, and evaluate the function of aptamer-functionalized macroporous hydrogels in controlling protein release for angiogenesis. Vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) were used as model proteins. The data show that anti-VEGF and anti-bFGF aptamers could be uniformly incorporated into macroporous hydrogels for st
