Abstract

Human pluripotent stem cells (hPSCs) hold great promise for applications in regenerative medicine and pharmaceutical development. Such applications require cell culture methods and reagents that are chemically defined, xeno-free, scalable, and low-cost. Herein, we describe non-mechanical passaging of hPSCs on spider silk films under chemically defined and xeno-free conditions. The cells were dissociated into single cells or small aggregates using Accutase or enzyme-free dissociation buffer and then passaged to spider silk films, where they expanded in monolayers until they covered the surface. Cells cultured over 10 passages on spider silk film remained karyotypically normal and pluripotent. In conclusion, a novel method for passaging dissociated hPSCs under conditions that are compatible with clinical applications is presented. The method is cost-efficient and may be useful for both research and clinical applications.
