Overview
This protocol focuses on utilizing the inherent ability of stem cells to take cue from their surrounding extracellular matrix and be induced to differentiate into multiple phenotypes. The overall goal is to create a composite matrix made from natural biomaterials that can deliver and differentiate stem cells to assist in wound healing.
