Myocardial fibrosis is a hallmark of cardiac remodeling, which can progressively lead to heart failure, a leading cause of death worldwide. The effector cells of fibrosis in the heart are cardiac fibroblasts (CFs). There is currently no effective therapeutic strategy clinically available to specifically attenuate maladaptive responses of CFs. Large-scale applications such as high-throughput drug screening are difficult due to the limited availability of human primary CFs, thus limiting the development of future treatments. Here, we describe a robust induction protocol that can be used to generate a scalable, consistent, genetically defined source of quiescent CFs from human induced pluripotent stem cells for cardiac fibrosis modeling, drug discovery, and tissue engineering.
