Development of Micro-Patterned 2.5-D Scaffold Using Micro-End-Milling

摘要

We fabricated micro-patterned 2.5-D scaffolds using micro-end-milling with controlled pore and island sizes and interconnectivity to determine the effects of the micro-patterns on the cell culturing process. Micro-end-milling can easily realize a high aspect ratio and accuracy, and can be applied to various materials, including those that are biocompatible and biodegradable. Sixteen types of micro-patterned scaffolds were designed and fabricated using the micro-end-milling process. Fibroblasts were seeded and cultured to examine the viability of the developed micro-patterned scaffolds and their absorbed cell adhesion. The results confirmed that the fabricated micro-patterns functioned successfully as scaffolds.
