Tissue engineering is a promising aspect of regenerative medicine that is aimed at constructing functional tissues and organs. While progresses in tissue engineering have led successful clinic applications, challenges remain for more complex tissues/organs that require concerted efforts from multiple types of cells. One of the key issues in building replacements for complex tissues/organs is to mimic the organ’s complex natural organization using a mixture of engineered materials and living cells [1]. Electrospinning has shown promise as a technique to create the microenvironment necessary for cell growth and proliferation for tissue engineering applications[2–4], while multiple fabrication methods have been developed to manipulate live cells(e.g. cell printing) [5–7]. To this end, a system integrating polymer electrospinning technique and pressure-driven cell deposition method is currently under development for forming hybrid tissue constructs with living cells and polymers. This study focuses on examining morphology of electrospun fibers as function of processing parameters including working distance and solution flow rate.
