Abstract

This conference proceeding describes the culturing and expansion of mouse induced pluripotent stem cells (iPSCs) in hydrogel core-shell microfiber; the core consists of iPSCs and extracellular matrix (ECM) proteins, and the shell is composed of calcium alginate. This culture system is established by using a microfluidic co-axial device. The mouse iPSCs in this feeder-free 3D culture system expand with sustained pluripotency for nine days, even though their expansion ratio decrease to almost half of that when cultured by conventional 2D system on feeder cells. We believe that this feeder-free 3D culture system would be useful to obtain high-quality iPSCs to apply them in various fields including pharmaceutical and medicine, where contamination of feeder cells need to be avoided.
