Abstract:
Cardiac fibroblasts and fibrosis contribute to the pathogenesis of heart failure, a prevalent cause of mortality. Therefore, a majority of the existing information regarding cardiac fibroblasts is focused on their function and behavior after heart injury. Less is understood about the signaling and transcriptional networks required for the development and homeostatic roles of these cells. This review is devoted to describing our current understanding of cardiac fibroblast development. I detail cardiac fibroblast formation during embryogenesis including the discovery of a second embryonic origin for cardiac fibroblasts. Additional information is provided regarding the roles of the genes essential for cardiac fibroblast development. It should be noted that many questions remain regarding the cell-fate specification of these fibroblast progenitors, and it is hoped that this review will provide a basis for future studies regarding this topic.
