Abstract

Vascular endothelial growth factor (VEGF) has an ability to induce the migration of human umbilical vein endothelial cells (HUVEC). The objective of this study is to prepare several patterns of gelatin hydrogels for VEGF release and evaluate the 3-dimensional pattern of HUVEC migration in Matrigel by VEGF release. VEGF was incorporated into the gelatin hydrogel sheet to achieve the sustained release and generate the concentration gradient of VEGF. When Matrigel was put on the gelatin hydrogel sheet incorporating VEGF, the VEGF was released into the Matrigel to form a gradient pattern of VEGF concentration in the Matrigel with time and the area of VEGF released by the Matrigel depended upon the position of gelatin hydrogel sheet put on. In addition, HUVEC were seeded on the surface of Matrigel to evaluate the ability of VEGF released to enhance the cell migration into the Matrigel. HUVEC were migrated with time into the Matrigel to the direction and the position of VEGF released. It is concluded that the VEGF release induces the migration of HUVEC in Matrigel based on the concentration gradient and the position of VEGF formed in Matrigel.
