Abstract

Here, we describe how to efficiently direct human pluripotent stem cells (hPSCs) differentiation into self-renewing epicardial cells in a completely defined, xeno-free system by temporal modulation of regulators of canonical Wnt signaling. Appropriate differentiation-stage-specific application of Gsk3 inhibitor, Wnt inhibitor, and Gsk3 inhibitor (GiWiGi) is sufficient to produce cells expressing epicardial markers and exhibiting epicardial phenotypes with a high yield and purity from multiple hPSC lines in 16 d. Characterization of differentiated cells is performed via flow cytometry and immunostaining to assess quantitative expression and localization of epicardial cell-specific proteins. In vitro differentiation into fibroblasts and smooth muscle cells (SMCs) is also described. In addition, culture in the presence of transforming growth factor (TGF)-β inhibitors allows long-term expansion of hPSC-derived epicardial cells (for at least 25 population doublings). Functional human epicardial cells differentiated via this protocol may constitute a potential cell source for heart disease modeling, drug screening, and cell-based therapeutic applications.
