摘要
Nanofibrous materials made from bioabsorbable and biocompatible polymers have promising applications as tissue-engineered scaffolds. Genetic analysis of human umbilical vein endothelial cells (HUVEC) that attached to Poly(glycolide) (PGA) nanoifibrous materials prepared via electrospinning methods demonstrated high expression of Integrin v and VEGF receptor genes, which are known angiogenesis markers. In order to improve the function of the PGA nanofibrous materials for tissue engineering applications, we used a micro-patterned template instead of a flat collector in the electrospinning process. "Micro-patterned nanofibrous material" demonstrated uniformly sized dents with diameters of 200 micrometers and depths of 36 micrometers. The dents were regularly spaced, with a 250 micrometer space between two dents. These sizes are similar to that of the template. We will discuss further applications of this designable micro-patterned nanofibrous biomaterial.
